So another good ole baffle removal from our valve covers. I just took mine off today, got the OEM rivets off and took out the baffles, and there no surprise how much build up was inside.

I am not sure if anyone has installed rivets instead of tapping new threads and using allen or button type fasteners, but I tested the rivets in the holes and they hold very tight, even after drilling them out, the base of the rivet did not loosen. I will be using rivets and posting up pictures and updating the thread. The cover will be complete tomorrow, just have to clean the cover tomorrow and baffles.

 

i drilled and tapped mine for allen head bolts. Just easy to remove if you ever want to do it again. MR2's came like that from the factory, they dont even lock wire them or anything. Just a dab of thread locker i believe.

 

That is a very good idea you mentioned, I riveted the holes last night, but the allens would also be a good idea.. hmm, they're easy to get out, maybe I will go with allens. I am curious if rivets are more reliable then a bolt?

Maybe someone can chime in.

 

Bolts are easily the better choice. You wouldn't use rivets to put an engine together, right?

 

Rivets I believe are a good choice too. I would want some engineering behind a lot of it to know if a bolt it is better the valve cover is done and red locktight around each rivets, I even tested taking rivets out and it was very snug in its corresponding hole.
