phase signal: checked wiring and gap. all ok. phase signal still missing at high rpm. anything else to try apart from new sensor? where to buy one?

smoke: engine smokes when revving up after being on idle. no smoke or fumes under oil cap or in breather system. compression check ok. no smoke on start up (valve guide/stem seals ok). new turbo. thinking it must be turbo oil drain pipe partially blocked, mate who fitted trbo didn't check it.

any ideas please folk?

 

re smoke: checked turbo oil drain and it was clear. removed oil feed from turbo and opened wastegate and ran the engine. still smoked when revving up after being on idle for a while i think that has eliminated the turbo as a possible cause.

checked the breather. hose from black block breather to red and black 3 way valve thing was cracked, and hose from 3 way to inlet plenum cracked and missing one way valve. will try and get these new from ford and see if it helps

 

If I were you I would just get aftermarket breather...

 

Nick,

Personally i dont like the iea of plumbing all that misty oil cr@p back into the engine, all it does is serve to feed the engine with some oil as well...probably hence the smoke....

Like Azrael i'd say get a decent breather on it...

 

thanks for the replies and consideration so far.

i don't like putting crap back into the engine either, but when i removed the oil separator and filter and hoses there was no crap in them.

the engine doesn't really breath through there when it's running - it just smokes out of the exhaust

i don't want to replace all the breather system on what is a std engine if i don't have to. i just wonder if the missing one way valve and cracked old hoses can case pressurisation somewhere in the engine which pushes oil somewhere during idle that then burns when revved.

Azrael, did you ever stop your escos from smoking? i was following your sad story and it sounds very mch like what i have with this car. was it your turbo for sure? i think it can't be the turbo because we stopped the oil flow to the turbo and it still smokes.

 

From you describtion it seams to me more like valve stem seals, but I can tell my story.

In the end it was fixed by Garett dealership changing whole turbine core and exhaust housing under warranty. They did custom dual oil seal on teh exhaust side for me as they said Cossie engine has turbo slightly leaning to the rear which makes oil gather under the rear seal.

When I had those prblems turbo was leaking so badly there was actually some oil in the exhaust housing all the time so it didn't stop to smoke after being disconnected from oil feed. But at least in theory even with oil feed removed if crank case pressurises the engine can bereath through oil return and smoke through there....

I hope I helped at least a bit.

 

mate mine did the same and it turned out to be the oil control rings.
a compression test will not pick up on oil rings you need to do a cylinder leak test

 

thanks mates, that's a few things to check on then. have ordered new breather parts, will fit them and see if it helps. if not, will do the valve stem oil seals as the car was sitting for a while and they have probably hardened.

we rebuilt the bottom end (but stupidly didn't overhaul the head when we had it off) and checked the rings and they were in spec.

 

When a friend of mine had greys fitted, they were overfuelling at idle. The car would idle fine, but blip the throttle and there was loads of dark coloured smoke. I know your engine is standard, but could your water temp sensor have failed, causing a rich mixture, which could also cause the high end misfire ? After sitting at idle for a few minutes, without blipping the throttle, what colour are your spark plugs ? If they're sooted up, would consider a new water temp sensor.

 

water temp sensor is fine jon. have had an s8 plugged in which shows you the actual temp and fault codes like that. thanks anyway jon

 

Nick,

I take it you're not getting an error codes for the misfire?

 

wih the s8 fitted, i get a phase count missing error, but no misfire or cut out. put the L6 back in and it's back. don't know if it's the phase sensor problem causing it. had a phase sensor problem on my other cossie, but that is running L8 and didn't suffer any misfire or anything. maybe it's because L6 is not as sophisticated?

 

I remember that the L6 doesn't give out the same Error codes as that of the L8...

Perhaps that is saying something.....

Level 1 and level 6 ECU's share the same codes:

Code Fault / faulty part
1+1 Inductive REV/TDP sensor
1+2 Inductive distributor phase sensor
1+3 Ignition timing signal (ECU internal)
2+1 Inlet air temperature sensor (short circuited)
2+2 Inlet air temperature sensor (open circuit)
2+3 Coolant temperature sensor (short circuited)
3+1 Coolant temperature sensor (open circuit)
3+2 MAP sensor (short circuited)
3+3 MAP sensor (open circuit)

Level 8 ECU's have these codes:

Code Fault / faulty part
1+1 Inductive REV/TDP sensor
1+2 Inductive distributor phase sensor
1+3 Ignition timing signal (ECU internal)
2+1 Inlet air temperature sensor
2+2 Knock sensor
2+3 Coolant temperature sensor
3+1 Heated HEGO sensor (lambda sonde)
3+2 MAP sensor
3+3 Throttle position sensor
