Is the oil blowback line(from top of cam cover) going to a oil catch can or to the manifold? If its in the stock position (to the manifold) try putting in a oil catchcan.

Check the breathers on your rocker cover, and make sure your pcv valve is opening up properly.

Sounds wierd that it's coming from your dip stick.

4agte's ABSOLUTELY LOVE TO BREATH, if you have just the std one breather, ditch it. i've upgraded my entire breathing system, cause i needed more

(i have a pair of red cam covers that were on my old engine that are for sale, can also provide -8 lines with the fittings and a small simota catch can :lol: )

would having the original breather system cause oil / vapours to come out when the BOV vents? or is that likely to be a problem on the turbo side? just noticed a fine mist coming out every so often...

could possibly, as the vapours from catch can go back to before the throttle body. and when that shuts, go out the bov. but at same time could possibly be the front seal on turbo

i do have a oil catch can allready and have sealed up the inlet valve piece and just have 1 goin frm the stanard 4age cam cover to a oil catch should i put 4agze cam cover on my 4age 1 pvc mite not owrk..

i got told if u have the inlet 1 goin into oil catch can wen turbo the boost gets forced into the catch can and can make it leak?

im just really hoping it isnt my piston rings because the motor is rebuilt

i took it to a shop to get tuned and got it back saying i have a masive inlet leak and turbo blowin and water leak so i was wondering if it was because ov a blowing turbo and inlet leak on a brand new motor if that would be why?

please if you guys could help because 4age turbos are new to me well turbos are lol

Sounds like your turbo is toast and you need to make sure you've bolted up the inlet manifold and throttle body properly.

Might pay to check your cam timing....if its a new engine cam timing might be a bit off and that can cause excessive breathing.
