my breather hole is shooting out grey smoke on my b16 head like never before like crazy. but none is coming out the exhaust just the breather. and it spits out a lil oil too. what could be wrong?

 

bhumpppp

 

Pcv valve could be plugged up?

 

Don't sound to good. I'm seen other people with similar issues and had cracked ringlands. I would do a compression test and leak down test if possible and post the #'s.

 

where is the pcv valve on a b16 head?

 

x2 happend to me when i over boosted a few weeks ago...thats not a good sign

compression test time

does it sound like a subaru??

 

this happen to me whit stock CTR pistons using the NOS, one piston crack betwen rings. Now i use SRP slugs and Eagle rods. Check the compression in the all four pistons, it's has to be similar, make a leak down test and looking for a oil wet spark plug.

 

This happened to me on two motors, my first was a b16a on boost (compression test fail), took it out replaced it with a b18a on boost and its starting to do the same thing accept now its leaking oil out of cylinder 4s exhaust port and getting into my wastegate! no good! Maybe rings, a head gasket, or valve seals?

 

usually it's cracked ringlands that cause that, but it's not guaranteed to be that so make sure you do a leak down test.

 

also done this to a motor. cracked ring lands often have you blowing smoke out the exhaust as well since cylinder oil is getting burned like gangbusters.

 

what if i use "engine restorer" from the auto parts store? will it seal up the seals?

 

NO!!!!!!!!!

 

To late to use restore lol. That stuff never works. You have either burned thr rings or cracked the rings. Do the comp test and post results.

 

if i get new rings on a rebuild, do they have to be wiseco rings since i have wiseco pistons?
