i recently did a compression test wet and dry... 150 across.. what do you guys think... i thought i was the turbo cuz i did find oil in the charge pipes.. so i sent the turbo to get rebuilt and clean out all the pipes.. but its still smoking.. anyone have some advise

 

Valve seals or guides. Fuel washing cylinders. Bad PCV.

What color is the smoke?

 

Are you running a stock GSR block? Compression should be well above 150 if you are..

 

i know this has nothing to do with your prob.. butt where in el paso u from?? i lived there for a long time

 

you're right !!, it has nothing to do with it...yum yum LOL

Adrian,

1. your compression should be above 180ish on dry...
2. have someone follow you when you're driving, if smoke comes out at full throttle, it's usually your rings

if smokes comes out while deccelerating, it's usually valve guide seals
3. is it a bluish colored smoke ?
4. get leakdown tested, see if it's rings or valves

people say that its kinda of blackish some say blueish.. i check the pcv and also cleaned it out.. it looks fine..the block is done lowered the compression to 8:1 they said 150 was fine..
turbo crx i live in east el paso
the car usually smokes when i take off in first or when i coming to a stop.. i took it to the track and still hit constant times.. my mph went up 2mph..

 

Yep it sounds like your rings have seen better days. What is probably happening is that small amounts of oil are makeing there way thru the ring seals, its called oil blow by (dont quote me on that) but anyhow yes it would be a good time to replace those with a good set. The smoke you see is from the oil being burned up by the intense heat of your exhaust.

 

thanks to all of u.. i guess the best thing to do now is tear the block and rebuild it.. and once again thanks

 

nice to see someone local. do you go to the sunday night drags at the airport? i am from cruces.

 

i really dont go to the airport.. its a waste of time.. my opinion.. were usually at the illegals or thunder alley which i think already closed...

 

did u ever determine what it was???

and how hard/expensive is a valve seal change??and what could/would cause them to leak?

 

im getting smoke too w/ my turbo, yeah theres no smoke when im on boost or at idle, i usually see a puff when im slowly accelerating.

how hard is it to change valve seals and piston rings? where to get and how much will they cost.
