excessive amount of smoke after rebuilt (and more)HELP!
 
Long story sort,

I had a rebuilt done less than 3000miles ago (changed ALL seals) and then I blew up one of the apex seal. The guy who took the engine apart changed Only the broken apex seal. Donīt know is that a suicide or should I have replaced all O-ring too, even they are allmost new?? Anyway now the car smokes a lot especially during idle but on a highway donīt see or smell smoke or maybe it just fades in the air. Compressions are 120/105 I know the difference is big but the reading are good. Canīt say is the smoke blue but it smells oil..

I also have difficulties to zero the timing. Feel like thereīs not enough space to rotate the distributor to zero the timing. If I take the CAS up and turn it one tooth (one way or the other) I canīt even see the timing marks.!?? And my ilde being +1000rpm doesnīt make it any easier.
When timing is allmost zero(2-3mm from the mark) car starts good and the idle is stable but when we finally got the timing to zero(at least we thought) idle is very rough and the car hardly runs.

Whatīs my next step to solve this smoke problem and did I have a bad rebuilt or is there still hope?

is your car turbocharged? if so it may be a bad turbo

I take it the rotor housing wasn't damanged when the tip let go?

If I remember right the housings were ok but there was i few small scratch on the front or rear housing (donīt remember which one) but it is fixed now. But could those scratches been able to damage side seal or the O-rings?

I donīt think itīs the turbo even Iīd hope it would be rather that than the engine. Turbo is allmost new... but everything is possible.

What is the easiest way to check the turbo and the engine. What should I see if I take the DP off of the turbo? Or do I have to take the manifold off to see if thereīs oil in the exhaust ports?

if the scratches were in the oil seal tract then they could have damaged the oil seals or at least they could be trapping oil and allowing it to pass to the combustion chamber each pass and allow it to burn.

checking the engine for oil seal issues is usually as easy and pulling the plugs and reading them.

How much oil are you losing?

I checked the plugs and they looked ok at least to me.

Donīt know exactly but donīt have seals in my mid silencer and itīs leaking oil so I would think Iīm loosing quite a lot..? If I have oil in my IC piping doesīit refer to turbo or the engine or can you make any conclusion?

bump...

i seem to have the same probably. can't figure out what it is.

except mines its a 89 TII with a fresh rebuilt... have a little over 100 miles on it so far... it was smoking when i got it back from the rebuilt, thought it was the turbo so got that swapped.. but still smokes during idle like before the turbo was changed.
