I'm purchasing parts to do the job next weekend. 2 weeks ago I just got my valve covers/valve cover gaskets/grommets replaced, so they're all brand new (free work after I purchased from the dealer).

Since the parts are new, do you still recommend a new set?

Thanks,

 

As long as they were properly installed, they should be fine to reuse.

Replace only if you had oil leaks. My covers have been off twice with no leaks.

 

You should be fine, of course clean and inspect. Don't forget to use a dab of sealant where the jtis calls for.
