Hi, first time poster and not sure if I'm in the right place but I have a reco LS1 with mild cam and after driving for 10 - 15 mins I get a loud tick coming from the rear passenger side of the engine. If I turn the engine off and wait 30 secs give or take, then start it again the tick will fade away after a few seconds. This has happened all three times I've taken it for a drive. Btw the engine hasn't even done a 100 kilometres yet. Does anyone have a theory on this?
