Ok a mate of mine is running a stock ECU on his FRST. he has just re-shelled his RST, engine has been out for around 2years, as he rebuilt he shell from new. he had rebuilt the engine just before he taken his rst off the road, he went and fitted the engine and turned it over by hand, got it running and RAN it back in, then check the comprestion, he went to ford fair and poped his head gaskit, the car before had no smoke, at all. bar fuel smoke, he has rebuilt the head and went had it all tested, the head tested, came back fine. fitted the head and ran the car, it started to smoke like a coal engine from a train, when he gives it some shit it clears, when he lets off wait 30-50seconds and it puffs, like a mean PROPER puff, fills the road. it smells like burnt oil. Its not blue, its not black, its a fade of white. it smells like oil and wanter mixed, such as burning smell.

ok,

hes not having any problems on boost, its all fine, its boosting up as it should and is holding a good 10psi of safe boost, but, i removed his oil breather system and that had alot of gunk inside, removed that and cleaned it up. used a compressor, i also remove all oil pips from the turbo ect. removed anything that may have oil or air going throw it, there all clean, we taken it out last night and its not cleared, on tick over it smokes when hes been driving, but after 2-3min it clears, and nothing. and same with start up.

there is no play in the turbo shaft, no in and out play other than the normal up and down VERY little play, like normal shafts are.

its burning oil of course, its chuffing real bad and is rather funny at times lol. but hes getting fed up, he wants to make sure my advice is correct as hes only owned the car 18months and is the first RST hes owned. rebuilt.

i told him that the oil bearings inside the turbo ''which is what he thought also but wasnt sure'' is causing all the smoke ''on over run''

am i correct in saying so? that its the oil bearings inside the turbo that have gone, there is no leak from the mainfold or turbo btw

it does sound like the turbo, is it still on a T2? if so they normally suffer on the fiesta's, they wear the seal, shaft groove & bearing housing normally.

oh and also, the engine has not had an oil change since the HG went, dont ask why, im just a mate and i like to let him make his own mind up and try repair his own car, so he gets more from it, but when he needs me im there. rather than me take over as i wanna see him have the joys of building his own motor. and having the good will to build it even better if there would be a next time.

oh and it dont look like HG smell, or puff, its chuffing like a coal train, which has made a rather good joke.

''Dont forget to fill up your coal engine''

''Ay mate, thats old school Coal mechine''

''Asda is selling some cheapo coal bro, Get down there''

''Whys your car smoking so bad?? ive just fitted my new coal powerd engine''

''Dude, its bad to smoke, your car must be on 60fags every time you run your car''

we've had some cracks regards his smoky joe, But now its time to become more serious and find the problem and get it fixed

forget the turbo, it's rings, on boost the pressure in the cylinders will stop oil being drawn into the bores, off boost the vac the pistons create will draw oil through into the cylinder, this is what is causing the problem.

oil leak in the turbo should be showing lots of oil in the exhaust housing and on boost would be far worse, check for thrust bearing damage, i.e. in and out movement of the shaft.

also pull turbo off and do general checks, if there is oil in the exhaust ports of the head, then it's rings, if there is oil in exhaust housing, then turbo.

when i poped a hole in my piston and smashed 2 rings mine wasnt as bad tbh. smoke a little on over run but was low on compression.

i really never thought of that, i suppose its because of it being on over run'' but then again, that makes no different does it?

i think'' hes going to be compression testing it, and then removing the turbo, the last thing i wanna do is say. its ya turbo, and he buys/rebuilds a new one and its not, i rather get advice and work throw it, i have simple/s or kinda advance know how on RSt's but im not exspert.
