5 bolt valve cover leaks

I was hoping if they hit the intake like mine did he would notice that pretty easy, and he doesn't have a leak on that side so probably not the issue.

Cork haskets won't do it, been there
Gluing them won't
Tightening the hell out of them won't
Making sure they are flat won't

The problem on factory style heads is that the rail has an approximate 1/8 arch to it front to back and the cover is straight. (without the gasket set it on and push down on the back of the cover) the front pops up about 1/4 or more.
Same if you push down on the front (the back pops up 1/4 inch) and it's not warped valve covers.


I did mine exactly the same as Swifter is doing and mine are dry as a bone in the the AZ desert, but if I tell how I did it in a public post there will be a shitstorm of posts saying how stupid my solution was, how it couldn't possibly work, or that I should spend a bunch of money on machining so I can run Fabbed covers on stock heads that I don't even need. (I have stock heads and valvetrain) and I did it for the look and possibly needing them on a different motor because I got a GREAT deal on them.

This was before I put the headers on about 8 months ago, and they are still bone dry, so it can be done.
As long as you accept and deal with the arch of the valve cover surface on the factory head.

This is the problem, the valve cover rails on SBM and BBM are almost never flat,they have a serious arch in them preventing them from ever sealing with a cast valve cover that doesnt flex like a stamped cover. I mill the rails flat and it takes care of the problem every time.





Yayyyyyy, more leaky and defective valve covers!!! :-(

Here ya go boys and girls ... read up on the "crapsmanship" I've been discovering on aluminum MPs.

So far, more than 60 OWNERS have reported similar or worse problems. Yikes ...



Your photo clearly shows what happens when people try to crank the snot out of the bolts in an attempt to get them to seal when the heads themselves are the problem and not flat. You can't make cast aluminum flex and not expect it to crack exactly like in your photo. Its an obvious problem when you take the time to look instead of blaming QC at MP.
