I keep getting oil in the intake of my GT35 BB turbo. The turbo is brand new and hardly run any high bar yet. My mechanic say that the oil pressure is too high due to the balancers removal...Has any one have any idea what could be the problem?
are you plumbing bak your rocker cover lines bak into the intake pipe? how old is the motor? its pretty common for 4G's to have blow bye.. hence thats probably why u have oil there.

No my rocket cover lines go to a catch tank. The motor has been rebuild last year and probably you are right man. Time for another engine. Thanks.

I did compretion test and check for any blow by but the engine is ok, so i am guesing is the turbo, i change the oil line because it was too big to a smaller one and now is less oil but i still getting smoke when the turbo is on boost...is it possible that i damage the sealers???
wat color is the smoke? tingey blue? if so thats turbo seals..
if any other color its probably engine related.. could b stem seals etc..

The smoke is kind of white-blue...so it must be the seals but you have any idea why? Mabe too much oil preshure? The turbo is brand new.
what sort of turbo? roller/bush? where are you getting the oil feed from? whats your oil pressure set at? (stock? modified?)

what size line are you using?
disconnect the oil feed hose and hold the nut on the comp wheel so it cant spin and run the car at idle with the oil feed hose going to a container. run car for 15 seconds. then multiply the amount in the container by 4. that will be how much oil is being fed to it per minute.
aim for 1-1.2 litres per minute.
if its more than that you will need to put a restrictor in the feed line.
also, make sure the oil drain is large size and is totaly gravity fed and isnt kinked or crimped etc or at some stupid angle.
valve guides could possibly be fuked thats y u got blow by
