Smoking Cosworth

Hi chaps.

I have a problem with my 2lt cosworth engine and I cant way it up.

I was getting the car ready for mot and left it ticking over.

once it warmed up it started to smoke white smoke it was that bad that I thought I would have to cancel the test, and then it stopped.

So I took it for mot passed no problem.

I noticed while the emission test was going on it was starting to smoke again but luckly the test was over and the engine was turned of.

Drove it back from test centfre no probs.

So today we went for a ride out went to my mates about 4 miles away slight smoking.

We set of on a run drove about 50 miles stopping in traffic and lights no smoke at all car ran ok.

Left the car for an hour or so drove back to my mates had a cuppa drove home no smoke.

Stopped on the street whilst the wife moved other car of the drive smoked like a traction engine.

Dont under stand why it seems to be intermitant.

It has a brand new turbo techics turbo only done about 300 miles.

can any one help.

One other thing the engines in a kit car and the ECU is be hind the shelf were I had put my phone, whilst we were out the phone went off and the engine cut out , as soon as the wife answered the phone moved it away from the ECU engine ok again.

I have recently had a Mondeo do this, plugged my code reader in & the Lambda readings were all over the place, took it to my local mot station for them to tell me the emissions readings, the Hydrocarbons were off the scale, replaced the valve stem oil seals (head in situ) emissions then dropped to just above pass, replaced the poisoned Lambda sensor & all returned to normal.

White smoke is probably steam, suspect headgasket is going or anywhere water is near the inlet system. Is the intercooler water cooled or perhaps the turbo, I don't know the cossie set up? As for the cutting out it sounds like the ECU box is not shielded from RF interference. It the ECU is a metal box then grounding it to the chassis may help, if not then shielding in an earthed metal box will have the same effect. Best of luck with the steam, sounds expensive to me?

I had the stem seals done with new guids and valves, i went on suday to whitby did about 120 miles and streched its legs a bit didnt seem to have a problem its been a week or 2 since it last did it, you would think if it was head gasget or stems or oil rings it would do it all the time not just when its stood cos if it did it when driving it would be like a fog rolling in behind me. The daft thing is it might not do it for a nother week or so.

Ive been told that it could be oil breather thats not letting the engine breath and biulding up pressure pushing oil up the rings but why when stood.

My friend had this on a Punto Turbo... The turbo was letting oil past the seals due to reduced back pressure from fitting a Decat & straight through pipe.. his did it all the time though.

my mate had an escort Rs turbo and the oil sels had gone, i would have sed if it were more like thick white smoke the turbo or something was burning oil but if it were more steam like it could be head gasket ?

 

maybe
