I FOUND A CRACK IN MY MAGNUS INTAKE MANIFOLD WHEN I REMOVED THE INTAKE I FOUND CYLINDER NUMBER 2 AND 3 HAVE SLIGHT OIL INSIDE THE RUNNES ( VALVES LOOK CLEAN)

THIS IS A FULLY REBUILD HEAD OVERZISE VALVES VITRON STEM AND NEW VALVE GUIDES THE CAR HAS 4000 KM SINCE THE HEAD REBUILD

THE OTHERE STRANGE TING IS I FOUND OIL INSIDE THE EXHAUST PORT NUMBER 2 KNOW I HAVE A LEAK FROM THE EXHAUST STUD ( OIL GALLERY)

THere was no blue or black smoke of the exhaust, only when BOOSTING THERE WAS BLACK SMOKE FROM GOING RICH

Any ideas are welcomed
 
It's a possibility the seals on your turbo are done. Is there oil in your intercooler/pipes?

no oil ### so ever in the interccoler or pipes TB IS SUPER CLEAN, THERE IS SOME OIL WHERE THE MANIFOLD RUNNER MEETS THE HEAD ITS TRANGE THAT THE VALVES ARE SUPER CLEAN, SPARK PLUGS ARE CLEAN TO

IF THERE WERE A LEAK AT THE GUIDES AND OR SEALS YOU WILL SEE IT ON THE VALVES AND ON THE SPARK PLUGS RIGHT ???

THE OTHER THING IS THE CAR NEVER SMOKED FROM THE EXHAUST ONLY ON BOOST IT WAS SUPER BLACK ( RUNNING RICH )


TURBO IS A EVO3 16G SUPER CLEAN NO OIL INSIDE
 
What guides were installed? Bronze or iron replacement? What height were the guides installed?

How much boost? What cams are you running?

So the you have oil in #2 runner, and you think it is from the stud. The only exhaust many stud into oil is the bottom center, and that goes into an oil return port.

I do not see how that is getting into #2 runner. the outside of the head would have oil all over it.

thats the strange ting the mid runner has a little oil from the stud, however runner 2 has a loot more oil inside it


Upgraded Viton Valve Stem Seals

thats the rebuild gasket kit that im using right know, im using a FEELPRO headgasket compsite becouse i had no money to resurface the block
 
Dobt they are the good Viton, the good viton is blue in color.

You will get blue smoke at start up, and long idle time periods, stoplights, drive ups if the valve seals are bad.

Blue smoke all the time is rings or turbo.

Still what cams do you have installed?
What height are the guides installed?
 
Bad PCV valve. Sucking oil in to intake manifold from crank case.

i dont have a PCV I HAVE A FULL RACE CACH CAN

no blue smoke ### so ever even when idleing for a long time

im using DELTA REGRINDS 272 264

I have no idea idea about height its my friend that did it at his garage and this kid knows his stuff regarding 4g63


CAN IT be that the VITRONs are cheap????

Well I know my stuff about the 4g too.

Now you are getting in to the sketchy area.

Your friend, this kid that knows his suff regarding the 4g63.

He has the equipment to change the guides and cut the valve seats in his gararge?

If you ask, he should be able to tell you.

Ask him at what height he set the guides, to tall and the spring retainer can be hitting the valve seal.

thanks, the reason im saying this is because we had all the tools and the manuals for dsms at my old work place so we did all the job there


i can always take out the head and see ???!!!

Ok. I have no idea what a psv or psc is, so that explains why I've never heard of a full race cach can. LOL

Are you trying to say that you have two -6AN lines coming from the VC into a single can that is vented to atmosphere (a filter on top of an empty can)?
 
So your old work place was a machine shop?

I know a few diffrent ways oil can end up in the runners from bad guides or bad guide installs.

Did you read the links I posted?

i removed the pvc and use a 6an fetting, the can is vented to atmosphere


here is very little to almost no oil water in it can
 
Aside from the catch can setup (which is not the best by far)...

I just re-read this thread in detail, and it just doesn't add up. Everything from the IC pipe to the TB, the intake valves, and the spark plugs are "super clean", and the car isn't blowing any oil-related smoke at all. But, there is oil in the intake runners.

So, how is there oil in an intake runner when it doesn't show up anywhere on either side of it, and it isn't getting into the engine and being burned (which would cause blue or blue/white smoke)? :hmm:

The only logical conclusion I can come to is that everything isn't really "super clean" and there actually is some smoke, or there was a film of oil in the intake to begin with, but not enough to be burned off.

when i removed my magnus intake there was oil inside the runers of the intake manifold and inside the intake side of the head

and yes intercooler pipeing, intercooler tb are super clean i meen no sign of oil nothing even the exhaust there is no liquid

the intake dose have a little oil film inside it however IT IS inside the runners only

SO do i take the head appart or not ?
 
Assuming that the oil is getting back into the intake from reversion through the head, the only likely culprit would be valve stem seals...but I would expect at least some smoke when the car is first started.

With the right tools, you can replace the valve stem seals without removing the head. But, you may also have some cracked or improperly installed guides as Bogus alluded to.

well i em changeing the timing belt and installing a new tranmission

so the engine will get out of the car anyway

my last question is shodent there be more oil inside the valves ( combustion chamber) and on the pistons because right new there is nothing exept for some carbon build up
