Does anyone know how to fix a damaged valve cover?

 

How much damage?

 

I have a few with everything from stripped threads to chunks missing.

 

Chunks missing=good luck
stripped threads? I assume you mean for the spark plug cover? Get a drill and a tap, or possibly just chase the threads and be careful.

 

A spark plug cover would be an ignition coil, he is referring to the valve cover, which covers the internals of the head. Best thing to do is have a machine shop helicoil the threads for you unless your really good with a drill. For chunks missing, I believe your only solution would be to find a new valve cover or use some JB weld as welding is out of question with it being made of magnesium.

 

lol spark plugs thread into the head not the valve cover, all the valve cover is, is a cover... you cant fix ones that have chunks missing. stripped threads he means where the spark plug cover goes.. you can retap those pretty easily

 

thanks everyone. But I still don't have the answer I am looking for.
Here's the next question then, what to do with the damaged valve cover? I know Mg is an expensive metal. Any ideas or past experiences ?

 

Fixing the holes where the spark plug cover bolts to the valve cover can be done by carefully taping the holes with larger threads as mentioned before. I would think that replacing it with a cheap used one would be less expensive and better looking than having it "repaired" by welding.

 

I would buy a new one dude.

 

+1 buy a new one!!

 

Take it to a metal recycler, you may get some kind of $ out of it.

 

Buy a new one. when i got my car all spark plug cover blots were stripped and i found a valve cover for a 100 and you can get it painted a nice color before hand
