ok i started a home made project on a 86 crx not too long ago,
but the point is that after driving around for like 10 mins my car starts smoking alot at the stop lights unless if i have it reved up a lil higher. and once i take off it stops smoking and continues on normal.
and the motor is rebuilt with turbo pistons
its a D16A1 DOHC from a 89 integra

any good guesses????

 

maybe your turbo seals are shot.

 

or your valve seals

 

do you have a restrictor in the turbo oil feed? if not, check out one from ATP turbo , or many other places.

 

turbo seals are a possibility, but you said it only does it at a stop, when its idling. Oil pressure increases as the motor increases rpm's, so your smoking problem would most likely get alot worse when you accelerate. you have alot of vacuum at idle, maybe your pulling oil through some shot valve seals and burning it up in the chamber.

 

cant be valve seals becouse the motor is rebuilt like i said at first. and for the restrictor, it has one already. and right now its gotten worse to the point where it smoke most of the time now. but i did unplug the oil feed line and the smoking stoped, so for sure it has to do with the turbo.
so probably turbo seal??? cuz the turbo is used
or any other theories??

 

oh yea and also, its water cooled? does that have to do anything with it? should i connect the water line?

 

Turbo is shot.. replace with known working unit.

 

that feed line is HUGE!!! a turbo does not need that much oil. get a -3 line and a restrictor fitting.

 

wheres your intercooler man?

 

thats what i'm wondering

or he's just going to wrap that pipe with dry ice

 

oh the intercooler wasnt on at the time for that picture, that was before i blew the motor and had to rebuild it. but it does have one, just aint that big though

so then... i need and even smaller restrictor than what i already have??
my oil press is 20 idle and 40 full throttle if thats any help?

thats pretty low....

you have a restrictor now? what size is it?

 

is that pressure at the turbo, or pre-restrictor.

the feed line will work, if you've got a restictor, its not big deal

 

well just ordered the rebuild kit for the turbo so hopefully ill b good.
doesnt smoke with out it so ill make sure i update yall once its back in.
thx 4 the advise 2 every1 who spend there time throwing in a guess
