/6 valve cover leak......still Options

[Dr Evil]

So I got the new silicon covered valve cover gaskets and put them on last time I ran the car hoping that this would solve the oil incontenance my engine is suffereing.....nope. Then I recalled that I may have been expecting a bit too much from these new fangled gaskets. My old valve cover has some corrosion on the mating surface that is potentially the cause, or at least an exacerbating factor of this leak. That plus the tooling marks on the head probably did it in. Thus, I just scored a good deal on some turbo valve covers (they realy have come down in price for new, though) and hope to have them in by Fri.

Some thoughts about hte other part of this problem, the mating surface of the cam towers.
Q: Could I fill in any tooling marks with a filler of some sort and sand smooth? ex; quick steel, jb weld, etc.

So long as this compound is not heat sensitive and can withstand oil I think it would work.

Comments?

Evil one,

Did you set the valve cover on a flat surface yet? Had a couple cars come to me with leaks and the lower covers were "warped".

Typically you should be able to get a non leaking seal with the standard thicker graphite gaskets. There is some manual out there that says to torque the nuts down to something like 6lbs which just doesn't cut it. They need 40-45lbs torqued from the inside out in the typical cross pattern.

If you have a 4 1/2 grinder and want to put on turbo valve covers. Grind away until you can put the cover on with the engine in the car. Easy. Done a few, takes about 15 minutes to do both and you only take off just what you need.
