When I drive my car in boost for the most part it's fine with no smoke or very little smoke...

However after boost the car will spit out a puff of smoke...

The motor was built and broken in...has 195 compression across the board with 9.0:1 compression pistons...

I'm guessing its the pcv system b/c it's ghetto rigged b/c I don't have a full understanding from it...

Anyone could help???

 

Help

 

its hard to say but thats usually your rings. its kinda of normal after heavy load to let out a little puff...to a certain extent tho

 

Yeah true a little smoke no big deal, and it's funny b/c it doesn't do it everytime...

Could be the rings? The compression seems good, wouldn't the compressiin be outta wack with bad rings? The car has about 1200 miles on the rebuild..rings for sure should have been seated by now...

My break-in process consisted of about 15 mins at idle to make sure everything was ok. Drove it stock ecu stock injectors and no boost for about 800miles, then mase got here from florida and we did a compression test and it was 180 across the board which was ok so we tuned it to 12psi and it drove well, don't know if it was doing the smoke thing tho...from there we did another compression test and it was at 195 accross the board...so it rose like the rings weren't seated but it has been about 1200 miles since the rebuild and there shouldn't be any reason they haven't been.

 

 

No help maybe more info is required???

 

could the carbon build up yield a higher compression #'s?

I got 100 miles on my rebuild, stock injectors, stock ecu all turbo goodies but I drive it like a baby, NO BOOST. I did notice the other day very little smoke coming out of the valve cover breather at idle. Now this could be cause I dripped oil around there when I was refilling the oil.

I'm not sure if this is normal, but when things do heat up they vaporize anything thing that's on them. I thought at idle the PCV was in VAC sucking in air, I think there's a long thread about this. Im going to do a compression test tomorrow just so I have piece of mind.

bump for this guy, I think we are in the same boat.

 

alot depends on the clearances used for the build

 

Earl built the motor pretty tite...I seriously doubt it's the bottom end...unless I messed something up in the breakin.

 

valve guides or seals or both

 

I'll try the valve guides I guess...the valve seals are new oem.

if you do guides you have to buy new seals any how , they cant reuse them

are you going to pull the head your self?

 

I dunno yet...prolly sean so I don't fugg shi up.

 

I had this same problem with my d16Z6 a couple of days ago. I pulled all of the plugs to look for oil/oil burning on them with no luck. Then I pulled the turbo and saw that the turbo was starting to leak oil through the exhaust side seal.

 

Well...the turbo was off and it was still smoking thru the manifold so even without the turbo in place same problem so it's def. something internally not right.

 

smoking is good.
