HELP....... Just got my engine back together and installed. i got it runnng today and heard some valve noise. i pulled the cover and found two of my rockers loose. one of the lash caps appears to have fallen down my oil passage. Drained the oil lookng for the cap to no aval.

WHAT DO DO NOW???? i have a Canton pan i know there are some baffels in the pan not sure if i'll even be able to get to it. Do i need to pull the engine again? is there any thing else i can do?
