1jz rattle

[suprachris]

I have a 1j mk3. Just go it running. After building temp I get a rattle in the top passenger side. Can't decide where it's coming from. Already changed the tensioner pulley bearing. If you you tube 1jz rattle you will fine a stock soared with the same sound. It's not rpm dependant. If I give it the slightest if throttle it goes away. I will be inspecting the timing bet tensioner tonight
Was curious if anyone else here has the same issue. 1jz non vvti. Thanks in advance.

I have not found the source of the tapping yet. It's not a rod, or valve issue. The sound is the loudest at the timing cover backing plate. Cam caps are quite, middle and lower part of the bock sound great. On cold start and at operating temp. I'm at a loss, have not pulled cam gears off yet to see if the backing plate is hitting the cams. Guess it could be that if it was damaged in shipping. Some how I doubt it.
