Pretty sure ive dropped a lifter in the vette. First noticed a fairly quiet ticking noise yesterday, and on a cold start this morning heard it again, a bit louder, and with a metallic click. Now that ive heard it a bit more closely im fairly certain ive got a lifter thats decided to go south on me, possibly spun in its bore (being rollers, thats no good ) or maybe lost the needle bearing on the rocker or some such.
Teardown to start this weekend after a few more tests, hopefully with pics to go with it. If its a lifter...it may be time for a cam
