I did a search on this subject and didn't find the answer I'm looking for. I installed some Crane 1.7 RR's a few months ago and they seem to be really noisy after it warms up - kinda chimes right in with the exhaust leaks, but that's another story...
When I put them in, the engine wasn't hot by the time I got around to adjusting them. They all went in without any shims at all. I adjusted one cylinder at a time, made sure both valves were closed, tightened till the push rod just stopped turning, then cranked it down tight. Each one tightened 1/2 to 5/8 of a turn after the push rod stopped.
Does that sound like I did it right, or do I need to go back and re-adjust them with the engine warm?
