So, I changed the valve cover gasket and bolts etc. Some of the bolts went in nicely at 10 nm, some won't grip at all and keep turning forever. I guess someone at some point has stripped some threads in the block?

What to do?

I would be taking them back out and inspecting the threads. I would be helicoiling them and using new bolts if it was my car.

M20 or M5x?

M20s should have studs?

If the threads are stripped you will need an M6 helicoil insert.

Thanks. It's an M42. All the bolts are brand new from BMW (as were the gaskets)


An M6 helicoil insert, I'll have to research that.

Easy to use? Do I have to tap them in or drill them or owt?

Can you get them upside down?

Should I do all the threads or just the buggered ones?

They are easy to use, if you buy a helicoil kit, they come with everything you need. This is the kit I've got

They are pretty self explanatory, but I'm sure there is a decent guide on YouTube.

I would inspect the threads, and only do the ones that need doing.
