Turbo Adapter seals

[Chatmanboy]

If the bottom seal on the adapter is cracked can that cause a good amout of oil to leak? i thought it was my oil drain pipe because that had a crack i fixed it but oil is still leaking on the exhaust and have my car smoking from the bottom... So can that be the problem?

Which adapter are you speaking of?

Have you checked to see if one of your valve covers or the rear intake seal is leaking? If they are leaking they will drip down to the crossover pipe.

I had this same situation three different times from three different sources. Here the are in the order the occurred and how it was fixed.

1. Oil pan gasket. Replaced with a Cometic gasket as I recall.

2. Valve cover gaskets. Machined the valve cover contact point on the heads flat and reinstalled new gaskets.

3. Leaking transmission line. Replaced transmission lines.

The dye test is the oil will show you where the oil is keaking from. Good luck, Brad

Brad's right. Get some of the oil dye and you can see where the oil's coming from.

You can get the dye from any parts store? The adapter that connects the Turbo to the intake. So I will check the valve covers because its definitely oil has the transmission leak but fixed that also.

At AZ it's on the A/C murph. I think we charge somewhere around $6 for the bottle.

There should not be any oil near the cone adapter that connects the Turbo to the Intake. (no oil flows there)

 

[racemybuick]

in total agreement with Herb on that one!! NO oil should be in our on that adapter from turbo to intake unless you tossed a seal in the turbo... (I had that happen once...)...


Anyway, what side is the oil leaking on? Is it leaking on the manifold or crossover?

OK. Its on the passenger side leaking down to the crossover pipes

 

[Boost231]

also some times you get a leak on the back of the intake where it meets the block and heads. you can look down by the knock sensor and see if there is oil in that area

 

[TurboRegal84]

Sounds like it is the valve cover or the rear of the intake leaking.
