Re: Engine Oil Leaking into Exhaust manifold
When you replaced the valve cover gasket. Did you use gasket sealant? I know on both my Mx's that on the left lower corner, it leaks like a MF. And leaks down on the Alt. It's clean as a whistle with the sealant.

Re: Engine Oil Leaking into Exhaust manifold
I don't see why a leaking Valve Cover could get engine oil into the exhaust manifold, a leaking valve cover would just pour the oil out in the engine bay or in the spark plug holes
maybe it's a sticking valve or something ?

Re: Engine Oil Leaking into Exhaust manifold
You could buy a Compression gauge, and test the compression on the engine, they are pretty cheap, I payed 25$ for mine, and I'm from Denmark, so in the states it's properly a lot less ![Razz :P](./images/smilies/icon_razz.gif)
and it's really easy to test, just disconnect the Distributer and remove all the spark plugs, and screw the gauge in and crank the engine![Smile :)](./images/smilies/icon_smile.gif)

Re: Engine Oil Leaking into Exhaust manifold
Thanks a lot for your responses , in related to the compression testing what exactly will it reveal ?
