How can i stop the oil leak from my M&A valve cover, it seems to be leaking in the back on both sides..then the oil will leak down the block and onto the crossover pipe...I hate seeing the oil smoke at the stop light...does anyone else have this problem :fragez:

What kind of gasket are you using and how tight are you tightening the bolts? They should be snug and then maybe another turn at most

I ran M&A's on the 87 for 2 yrs w/ no problems. I used a rubber type of gasket from NAPA i think. Trim it to fit the cut outs on the valve covers as necesary and glue them on w/ 3M weatherstrip adhesive. 8001 is the yellow, not sure of the black part number. Let the glue dry and then reinstall and try not to frig up the gasket when installing. If your still running a/c, its a bitch but can be done.
Good Luck

I also glue the gaskets to the cover w/ "gorilla snot".
when I put them on, I always tighten the lower bolts first, then the tops...works for me..... :rock:

Since the orginal rubber gasket ripped, i`ve been using the Ultra Black gasket maker around the heads then placed a cork type valve cover gasket on top of that..I thought it would seal :albert: but it still leaks, I want to get it fix before i drop the engine in 2-morrow...I will go to napa and see with they have today

I gave up on cork after last year. I tried what you did in frustration and it didnt work either. I am trying the Fel Pro rubber gaskets this year, and if they dont work I am getting the ones with the metal reinforcement next.
My leak was the same as yours, right onto the crossover. Smoke city!

Try buying stainless 1/4 20 rod, cut to length and make studs, 1/4 20 nuts and washers, and better clamping force, If motor is out of car you can slide the gasket over the studs.

Whats the difference between using studs and tightening the bolts? Wont both just distort the valve cover and cause leaks? I can see where studs help in an application like holding cylinder heads on, but I dont know if the same applies here where the bolts arent tightened as much

Rubber, no sealant IMO.

Funny, the TTA valve covers have an embedded rubber gasket and mine have been off more times than I can count and they still don't leak. Granted us TTA guys don't have any options for better heads but at least we don't leak oil everywhere :add_schac
Anyways, with a cast aluminum valve cover, the easiest way to get it to seal is to glue a rubber gasket to the cover, let it cure, then install it. Under no circumstances would I ever use cork unless it is a Harley and we all know they leak anyways (actually, they just mark their territory).
