how to repair valve cover threads ?
hey guys I took my head to a machine shop a while back and had a valve job done & got a broken stud removed out of the head.
However I think they damaged the threads while removing it because I went to put my valve cover on and come to find out There’s no threads in the hole, the bolt won’t even catch, it just sinks straight down.
A heal a coil that fits the bolt won’t go into the head because there’s that little sleeve on the top.
Whats the best way to go about replacing threads/fixes ? I’ve never had to do this before
thanks In advance

Re: how to repair valve cover threads ?
That's tough dude. So I've only heard of this once but it's risky since this is a major component to keeping the head and block together tightly.
friend of mine did this and worked for about 2years then sold it so not sure if it worked passed that. Again, risky.
He welded the hole shut completely as solid as he could get it basically like a "fill" and then drilled, tapped and re-threaded it. Again, risky since you never really know how completely filled the hole can be but if you have NO other options, **** it go for it. I've seen worse try and get done but it's your motor not mine. I'd replace the damn thing with one that threads are good, that's only way you know for sure you'll be good.
