Loosing Water

Alright all,

Seem to have a problem with the car, it's using a lot of water, there's no apparent leaks and the oil is clear. Just wondering if anyone knows the Rover V8 engine well and may know what the problem is.

Head gasket blown pressuring system and blowing it out while driving?

Or liners have slipped?

When you say liners do you mean the cylinder liners. It's strange because the car never gets hot, doesn't matter how hard you drive her the temperature sits at 65 or lower.

Yes the cylinder liners. Later versions had a top hat liner to prevent this. 65 is cold even for a race tuned RV8 which run with a 74 deg thermostat.

There is no radiator cap, there's an aluminium tank with a screw on cap, inside the cap there's a small toggle that must be the pressure release valve but it doesn't blow out of there. At what age did they start using the top hat liners?

Alright all,

Saw my local rover specialists today, says it will be the head gasket, the tvr engines are heavily modified and he's never known a liner leak, to confirm this he's told me to take the plugs out and look at the piston tops, he said 7 will be black and one will be bright and shiny and washed clean so it's off to the shed I go to have a look

 

By the way somebody have the firing order for a Rover V8 handy in case I mix the plug leads up

So much for that idea, can hardly get the plug leads off, no chance of getting the plugs out, I'd have to take the exhaust manifold off to get in its that tight

It's already got plug extenders on, its because the manifold goes forward horizontally along the line of the plugs and there's two metal water pipes just above them combined with the angle of the plugs means there's no room to use the ratchet, if you put the extension bar on you can't get in for the inner wing and that's just on one side, the other sides got even more junk in the road

 

Cheers Mark
