If it is the head gasket leaking,whats the worst that can occur if the vehicle is continously driven like this,other than the oil seepage? 4977699-007.JPG (249 downloads)

Granted when it went i was reving her help to 6000 playing around then the nest day i start her up and coolant poored out of the head gasket area. It could go many miles before the head gasket let out but it is a game of chance and a sign it needs to be replaced.

Up top near where the valve cover fastens to the head is dry,as is the ledge next to it. The engine is slanted the opposite way of the leak as well,so I think if the leak was coming from the valve cover it would be very noticeable.The leak is coming from somewhere under the mounting area of the inake/Exhaust to the cylinder head as seen in the pic attached(Reference the red arrow) 4978209-008.JPG (247 downloads)

The pushrods are on the other side so the head gasket shouldn't have oil in that area...I haven't been able to find a good schematic of the oil gallery, it's possible that it's in that area but I thunk it's near the back of the engine... Maybe mention \6 in the thread title to draw in the guys that know the engine better...

Make sure it's not the valve cover gasket leaking and wicking down. The valve cover looks like it may be leaking toward the rear. How much oil is the motor using? I would not be overly concerned unless it uses enough that you might run it out. "Everybody funny, now you funny too."

Quote: Well it can't be an intake gasket on a /6 for one thing Well, techinically no, there is no oil sealed by the gasket. However, I have seen stains like that from leaking exhaust and even intake ports. The exhaust side leaks a mixture of oil/carbon/condensation/unburnt gas and the intake side will leak a mixture of gas/oil/carbon. Don't be afraid even if it is a head gasket. Changing gaskets on a Slant looks intimidating, but it ain't brain surgery. Biggest thing to do is before you start soak all the manifold nuts with PB Blaster for a few days. It will make life a lot easier. "Everybody funny, now you funny too."

A set of those stupid flex extensions and one of those universal jointed sockets helps a lot. I'd agree with slantzilla though, my block had a lot of staining around the driver side of the block from the exhaust. I used a feeler gauge and felt around the gasket area, come to find out some of the gasket was blown out. I didn't even hear an exhaust tick.

I know someone who pulled the Slant out of his race car and replaced a leaking rear main that turned out to be the back end of the valve cover gasket. "Everybody funny, now you funny too."
