Just about to refit my turbo, its held on to the manifold by 3 M8 studs, How can i make sure they don't come loose? was going thinking about locktight but will it take the heat or is them coming loose not a real problem on diesels? i could also lock two nuts on
Its not a problem usually do them up tight and they be fine
just wound them up tight then put 2nd nuts on them, hope they will be fine as its really hard to access them on a 307
Go get some new nuts from pug? They look to be special locking ones.
You can get locking nuts that use a metal insert instead of the nylon so they dont melt, I used copper lock nuts on my manifold and they never came loose.
