Would you guys see a problem with using non-factory nuts on the exhaust manifold studs? I'm missing one and another is starting to come lose, so I was going to run to True Value tomorrow and see what I could get in a grade 7ish nut to replace them with and some lock washers also. I was also thinking of using some locks from there on my exhaust manifold to turbo bolts. Any ideas or comment would be appreciated.

Thanks

grade 8 is better, but I am not sure what factory uses

The turbo to exhaust manifold bolts are the ones that really scare me since they are grade 11 I really just don't want to put them on there and not be able to get them off ever again. Could that happen?

when replacing my turbo, i lost two of the nuts for the exhaust manifold so i just went to farm and fleet and bought some regular metric nuts. i also used lock washers too, but im not sure what kind either are. they work fine as long as they get tight enough (kinda tough on that bottom right stud though)

That's the one I'm missing... Thanks all, Should be fun

good luck man
