Alright so... I had the standard stock exhaust manifold to downpipe leak.
Replaced with LCE header then did valve adjustment... Now there is an apparent sound in the top end that's super weird/haven't heard before on a 22r or RE.

I'm not sure it was not there before, may not have been audible.

Basically it sounds almost like a plastic oil can cap bouncing around in the valve cover.

It goes away once warmed up well.

Thoughts>>>???

The motor only has about 18k. Prior owner did the swap and as I have gone through other things have found A LOT of loose bolts and "havent swapped a motor before".

 

** seems to be around the rear exhaust valve area

 

I have not had an LCW header before but on other headers I have dealt with, it sounds like a weed whacker hitting the exhaust pipe. Never know what previous owners have done. I just go thru everything starting my way at the front and work to the back.
