two questions.
did you check the valve lash, and adjust accordingly? maybe the engine is fine, just needs a valve adjustment? the insight engine does tick, especially b4 warmup.
have you tried rev matching and double clutching yet? works like a charm to keep from grinding for many insighters, unless of course your tranny is too far gone. the 2-3 synchro is the first to go, but since purchasing my car a few months ago, I have double clutched all shifts, and rev matched all downshifts, and I can honestly say that it would appear that this practice brings synchro wear to a relative halt.
Otherwise, let the schucking commence.
