i have serious blow by coming out the lil breather cone on the VC...when i take the oil cap off with her running i can blow a quarter at least 6 feet in the air from the blow by...its blowing oil all over the engine bay...my question is what causes this...i was getting the car turbo street tuned when it started...

 

rings

 

Sounds like a stock engine with to much ignition timing cracked the piston ringslands and poof excessive blow by

 

yea its a stock gsr...damn too much timing....so maybe get another tuner....cuz it happened when i was getting the car street tuned.

 

Ummm, sure.. after you get a mechanic to put new pistons and rings in it.

 

new tuner is in needed becuase he shoulda been watchin for that while street tuning, and pistons and rings

 

did you have any breather/ventilation to begin with ?

 

You are going to need a rebuild or a new motor. Your not going to get out easy on this one. If its blowing that much oil out then the problem is serious.

 

i build my own motors...i already have the rings and bearings...and im looking for a set of pistons just in case the ringlands are cracked. ok so new tuner it is then.

 

no i didnt know i needed one for a stock motor.

 

Since you build your own motors, you should know that no matter if its built or not a boosted motor needs a breather.

 

well i had the stock pcv **** on it....i didnt kno i needed the aftermarket catch can....i have to read up on that and familiarize myself with it...any suggestions on the crank vent??

 

endyne kit aint bad for the buck ... tank might fill up fast on you tho

 

what happens when it fills up....

 

It'll overflow and be restricted for further venting...like a little kid blowing through his straw into his drink..lol

and I have two buddies with 400+ b series and both are using the stock black box...I don't see how they do it..no blown gaskets or anything.
I blew about about an inch of oil pan gasket out when I had my block vent hoses kinda pinched into a Monster can my bore/hone came out a little loose tho, see sig.
