/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?

If you VERY CAREFULLY dress the surfaces with a large flat file, getting any burrs out, clean it with brake cleaner of laquer thinner, over fill the holes with JB Weld, and again file it flat, it should work. It's a factory authorized repair for pitting in BMW heads, and I do it with Wasserboxer heads all the time. Works well, within reason. So Called "Turbo" valve covers will require some pretty extensive machining to achieve clearance at the suspension console. Early aluminum SC lower covers might be better, assuming they're flat. Are you sure it's the covers and not the rocker shafts? The Cap'n
