Anyone know if the studs for the motor mount at the frame is the same size as the exhaust manifold studs at the head? I have a strip one on the drivers side.

exhaust manifold studs are coarse thread on the head side and fine for the exhaust manifold side.

I believe that the motor mount are same thread both sides.

You will find something that will work at the VW parts counter, or a muffler place.

Will fit, correct thread for head, a bit longer. The VW stud has same thread each side, so you need to get a stud nut from them too. They don't use fine on the manifold side.

The stud in the chassis for the engine mounts are 8x 1.25. Coarse thread. I am sure they are welded into the chassis. It is a PITA to fix.
You might try using a 7x1 die to put some threads on it if it is badly stripped. Or a 5/16 coarse American die, as 5/16 is slightly smaller than 8mm.
Exhaust studs in the head are 8x1.25 head and 8x1 manifold. Centerline sells 8x1 brass nuts, I think. But if I understand you correctly, that is not where you are having the problem.

Before seeing your post I tried the double nut trick to back out the stud but stopped when it felt like I might break it.........making a difficult job worst.

Instead I did a stop gap measure till I figure out if I'm going to take it to the repair shop to fix.

What I did was tighten the nut down till it started to spin in place and put on a second nut and tighten it down on the first one. I was able to re tighten the first nut a little more then finished up with tightening the second again. Got it real tight.............thnik it will work???

As long as the second nut is tight, forget about it until the engine is out sometime in the future. I can't tell you how many times I have replaced engine mounts and found that the bottom nuts are not there. Makes changing a bit quicker and does not seem to create any problems. Only have to put them back on. I think you are good to go!

The second nut is tight...........

Erik your idea sounds better then what I did but I think I'm better off leaving it alone.

Thanks for all the help
