Sparepart

I will also be needing to replace the shock absorbers on an EXMO at some time in the future, they are okay at the moment. The last postings regarding this, I believe, were in the thread https://www.rhocar.org/index.php?/forums/topic/27038-exmo-suspension/page/4/. Might help.

This is an old chestnut. I have picked up lots of scraps of info from this and other forums over the years. In my amalgamated text file I have the following line. 'I' OR 'L' stamped next to number 4 spark plug hole= a leaded head most likely to be 1979 - 1982 in age. Now you are wondering about the age of your engine. Find the engine number stamped on the offside, near the front, should also match the V5 document. It should start with two capital letters. Then look at the attached screen grab from Burton Power to find the month and year of manufacture. For example my engine number has FR (June 1985) .... notice another FR in Oct 1966 .. cant be for a Pinto though. Oh! yes, also this assumes that the cylinder head and block are the original pairing.

All the comments on rear would be the same. Car on level, to just get a rear wheel off on one side use a scissor jack longways and thin piece of protective ply wood as close to the hub end of the trailing arm as you can get. Wheel will soon come up enough to remove, suspension is still compressed. To get both rear wheels up, use a small trolly jack under the differential with again ply wood to protect the casing. If you use a fixed lifting jack here then dont prevent the front wheels from from moving back, otherwise the jack might start to tilt. This takes a longer lift because the suspension has to travel fully down before the wheels lift, and I think a little postive camber develops. On the Exmo you have to be careful because the original design just used some nylon rope to stop the trailing arms reaching a point where they foul the static "yolk" and the springs pop out. If you have coilovers then I assume your car will rely on the full extension travel stop of the shock absorbers to prevent a similar thing happening. Depending on your jack you might need to drive the rear up on some strips of wood to get enogh clearance under the diff. In this position the car will not really be safe to do anything really because its like a wobbly triangle. So to make it safe I do what is described above, and use a piece of 2x4 wider than the body and place it just forward of the rear subframe, just in front of the thin piece of SS that sticks vertically down. I then put axle stands under each end of the wood. As for the front then I don't know for a series 3, probably one wheel up for a wheel change would be somewhere like at the inner end of the radius arm.

I think you will find that the manual attached above by dandan62 is the one issued for the S7. I say this because the tiny section on rear suspension indicates the use of the donor springs in the same place on the trailing arms ( I think the series 3 has coilovers at rear) and right near the end there is a copy of an insurance quote for the vehicle from Adrian Flux dated 24/6/93 (bit blurred) "in respect of the Robin Hood S7". Having said this, however, there is a lot that is the same in this manual for both S3 and S7 (and Exmo) the differences will be mostly in the front suspension design. I think that from the Exmo on, there were only build videos on VHS as IanS says.

This is very close to me, a short bike ride even ...... but alas, I will be trail running down at Dell Quay with BBQ after. Any way the EXMO is not on the road yet, the engine is at Banda Engineering in Portsmouth, just been reconditioned, awaiting collection. Enjoy your breakfast.

Just to be clear, in the image, the open hole below the coolant drain plug, is an oil LEVEL sensor position, not pressure. It was fitted on high end Ford models with this engine. The normal level sensor is of course the dipstick.

I attach a photo of a 205 block, exhaust side, there are two holes, the higher (here with plug in) is the coolant drain plug, the lower hole (sensor missing) is for the oil level sensor which was fitted on the Ghia versions of the Sierra. If you still have the Ghia loom complete there will be a plug for the sensor with wiring to take the sensor signal to the "Auxiliary Warning System", this was a swish display just above the gear lever on the dash that had all sort of warning lights, door ajar, washer fluid low, brake pad wear, fuel range ..... etc. I'm guessing that you don't have the AWS, or even the Ghia loom..... If it is the oil level sensor that you are looking at, it will have been left there becase it blocks a hole out of which oil will splash when the engine is running.

In the attached diagram, d and e are the temp gauge and fuel gauge, you can see that they both draw power from f, the voltage stabiliser. This power then runs to earth via the sensors, 27 is the fuel gauge sender unit and 26 is coolant temp sensor. As you can see it is only these two gauges that use the stabilised voltage, so if the stabilser fails these gauges will malfunction. You could also test that power is getting to the stabiliser, check F8 in the fusebox, and for power on the Black/Yellow wire to the instrument cluster, with the ignition on. Actually if there is no power on black/yellow other things wont work, like the oil pressure warning light (j/28), so if this is working there should be power to the stabiliser.

I bought an Exmo, it has a SS tank, and as dandan says the RHE tanks of this era were SS, just plonk a magnet on your tank to confirm. In which case welding on the alloy neck is not possible. You might consider bolting it on though. I see that Burton Power sell various sized pre drilled and nutted rings that can go inside the tank. They are designed to go with their Aero filler caps..... so not in the tank in their application ..... but they have welded nuts and are "horseshoe" type so could go inside a tank. The link below is to their catalog page, at the bottom, I think the ring for the 2.25 inch cap might do. You can buy a sheet of nitrile/cork gasket material and cut your own gasket. Anyway just a thought, would need more detailed investigation. https://view.publitas.com/burtonpower/2023-catalogue-pages/page/58

Since I have been totally rebuilding, I have removed the tank and washed it out with detergent, so I did the flange work during this, all debris was washed out and also vacuum cleaner round interior of seams. Now, if you are going to buy the Ford fuel tank grommet, I don't think that you need to pay the £45 quids that you mention. I did some deeper investigation. If you start with a Ford parts catalogue (link below) you can find that a Mk1 Sierra fuel tank grommet has two possible reference numbers, i.e. 72GB9072AB and 1492183 and also you can see that this part was fitted to other Ford cars, Granada, Escort, even Ka I think, anyway it's the part number thats important. Then if you Google something like "Ford 1492183" you will see that a grommet can be obtained for around £16. Below I include a link to the online parts catalogue I used (Select Sierra Mk1, and then scroll down to the section on petrol tank, then look at the diagram and see the grommet item number 10, then follow the link on the right to the part information that shows description and other Ford cars to which it was fitted). Below there is also a link to one of the £45 offerings, and you can see that in details they show the part number as just "149" which I think must be on purpose to obscure the full part number from web search...... or am I being cynical. Also a link to a cheaper provider of the same part. I hope this helps. https://www.fordopedia.org/ https://www.ebay.co.uk/itm/125331672244 https://www.ebay.co.uk/p/1709767924

I also had petrol fumes at the rear using the RHE supplied "box" type tank with the Sierra filler pipe rammed through the hole in the tank using the Sierra rubber grommet. As you say a new grommet is expensive, and didn't work too well. Now I am rebuilding the car, and have made a large bore filler flanged SS pipe to bolt onto the tank, and cut back the plastic Sierra filler pipe below the breather to allow for a flexible connection to the new pipe on the tank. I attach some photos of what I am hoping will fix the problem. There is an inner ring with a slot that has nuts welded to the lower face (not visible in snap) this was carefully manoevered into the tank and the flanged pipe sealed and bolted down with a cork gasket as shown. So there is no attempt to weld anything on the thin SS of the tank, all the welding is the flange to the pipe, which I did with MIG (should really be TIG) but I have tested its "Petrol tightness" by bolting it to a flat plate and filling the pipe with petrol and checking for any signs of seepage, left overnight without problem. I am also hoping that this will cure the other problem I had, that of having to fill the tank very slowly lest petrol climbing in the filler neck shut off the fuel pump at the filling station.

Just FYI, the Exmo build instructions used the same mounting hole and bush as used on the Sierra, the one that has a the bolt head that is scraping, as on your car. This means that the subframe is not rigidly fixed to the bodyshell, there can be some movement via the rubber in the bush, probably good for absorbing vibrations etc. Not long after I had mounted the subframe as per these instructions I received a build update from RHE telling me that some cars had failed SVA due to this small possible movement and safety concerns about bush failure leading to the subframe coming adrift. The new instruction was to bolt the subframe directly to the big steel plates using M12 high tensile bolts, on on each side. This involved opening a hole in the lower part of the subframe large enough to get a socket wrench head to the underside of the subframe plate through which the bolt protruded. The message to use a really tight nylock nut here and check it pre MOT every year was repeated several times. Consequently the bolt through the original Sierra bush became redundant.

You have fixed it, and I am still puzzling about what was scraping what ?, was something coming into contact with the road ? I am just curious.

Possibly a frivolous comment, but perhaps there is no air getting into the petrol tank, so after a while the pump is not able to extract any liquid petrol. I would have thought that if the tank is sealed, at some point the partial pressure would mean that when the pump sucks, the petrol starts to vapourise and either the pump pumps vapour or the petrol just moves back and fore in the pipe. I suppose you would hear a hiss when taking the filler cap off, if this were the case.

The pickup pipe in the tank has filter on the end. Could be a layer of crap in the bottom of the tank made up of reatively heavy bits, when the pump sucks the petrol up the bits are gradually picked up on the outside of the filter mesh until no more petrol flows. Then, left idle, the bits drop off under their own weight. You could run the engine until it stops and then as quick as you can pull out the gauge/pickup pipe to examine the filter.

In the original Sierra systems the pulsed input feed needed by the tachometer is a green wire that connects to the low tension (12v) connector on the coil. On the coil, apart from the thick HT lead going to the distrubutor, there should be a single (normally black) wire that comes from the ignition switch. The other connector would have two wires connected (normally green), one of which goes to whatever ECU you are using, and the other to the tachometer. When the ignition is on the the green wires should be live. The tachometer will have 3 connectors, one to earth, one to a constant 12v (with the ignition on), one with the pulsed feed from the ignition coil (probably green). So you need to get out a volt meter and check the wires that have not been connected, or visually look for the one from the ignition coil (probably green) that is probably not connected to the tachometer.

This is just a suggestion, I've not tried this, however have you considered fitting a smaller ball. That is chop off the current one thats too large, drill a hole and fit a smaller ball to match the Ford cable that you have. Various sized balls are available, they are used by RC model builders for example see the links below. https://www.ebay.co.uk/itm/154109713879 https://www.ebay.co.uk/itm/284753072675

Okay,Okay, I was a bit lisdexic with the numerals, I am a dislexic, agnostic, insomniac, I lie awake at night doubting the existence of dog.

I am exhuming this old thread because I have a very similar question I'd like to share. I have a 2.0 L Pinto, from a 1968 Sierra, I'd always thought it was a leaded head and have been using additives. Now I have it out of the car ready for reconditioning, I thought I'd check it for what is stamped on the head. As per advice in this thread I looked at the flat face next to number four spark plug, and saw a sort of asterisk stamped, so assumed a leaded head. However on cleaning up a similar face near number 4 exhaust port I see a letter stamped, which with the head in its normal orientation looks like an odd shaped "d", Turning the photo I took upside down, the letter looks more like a P. I have searched in loads of forums for use of a letter "d" in a pinto head to no avail. So I am now assuming that this head might be an unleaded head with the letter "P" stamped upside down near number 4 exhaust port. What do other members think ? ... photos attached.

£325 is the correct amount at the moment, see:- https://www.gov.uk/vehicle-tax-rate-tables/rates-for-cars-and-light-goods-vehicles-registered-before-1-march-2001

Well, ... to be PEDANTIC, the early kits used a Mini bodyshell for the passenger compartment. You indicate that both were built after 2000, so it's obviously unlikely that one used an old (ca. 1985) kit. However, if such a "Mini" kit had been used, then it might have retained the original Mini number as a "radically modified vehicle". For info, my car is like the A reg Beauford, built in 2000 yet having a C reg number like the donor vehicle.

Assuming that your engine is not running and you have a brake servo then the hiss is possibly the diaphragm in the servo forcing air somewhere like back to the inlet manifold. Disconnect the vacuum pipe and listen if the hiss changes or disappears. If this is the case then it can be ignored from the point of view of bleeding the brakes.

I have the same behaviour on an Exmo, obviously no use to you to know this, however in the days of SVA it wasn't an issue, the tester made no comment about having to unwind the steering to straighten out from a turn. I now know that most of the problem was related to the really poor bearing set up on top of the strut, causing lots of friction. As mentioned above by agent_z anything you can do to push the bottom wishbone forward and the top one back is going to help. If you have bushes that are pressed into the wishbones then perhaps you can press them off center to get some adjustment. Also I suppose that a lowering of the back of the car would have some effect on the angle of castor at the front, do you have any rear ride height adjustment, or raise the front as well. Oh yes, something else I found was at the universal joint where the column is connected ot the rack. When the weight was off the front wheels I could easily move from lock to lock just by pushing/pulling on the wheels. However when the car was back on the ground, the pressure on that UJ means that the small amount of play in it caused the top of the lock nut to slightly foul on a bit of poor casting on the yoke. Just a few strokes of a file to remove the casting mark and the steering was much free-er.

Out of interest I have done a bit of Googling, I found records of 3 RS Daytona Spyders, SAN 948S is the car that features earlier in this post, currently it is on SORN, so not on the road. 978 DJU is taxed so most likely on the road. There was also one in Holland NV-82_ST. One came up for sale on e-Bay as an unfinished project, this was a while ago, however the seller appears to be still active, they have a comment from a customer in the last six months. The seller's handle is "daytonalovercars", I attach a pdf of the ebay page showing this seller, so she/he can be contacted via ebay, and might know what happened to the kit. daytonalovercars-on-ebay.pdf

An early MGB roadster, bought as a project, everything I did to make it good brought more grief. Me towing it home with dad piloting it, he started the engine, to get heat from the heater, who knows what happened, but the next time I ran it, the big end bearings were grumbling and the oil pressure low. Replacing the bearings from below, engine in situ, sump off, one of the pistons dropped past the rings in the bore. Rear weel arches were replaced, this was expected, what was not was that going over a sleeping policeman both rear shock absorbers, the type with an arm, twisted up the chassis mounting point rather that move the arm, leaving them hanging in the air and the car bouncing down the road. Even though I had the clutch replaced, a little while later the slave cylinder rubbers burst and deposited all the fluid under the car leaving me stranded. Then as you might expect the main bearings started to rumble. The Twin SUs were never in balance for more than a week. There's lots more. Eventually I was surprised that a garage took it in part exchange for a Mk1 Ford Capri, what a relief.
