I've started to notice a bit of timing chain noise on my rebuilt L20b. It sounds like a diesel. Motor probably has around 800-1000 miles on it. I installed a new OSK timing set on it with new guides, tensioner, chain, upper and lower sprockets, etc...
I've been hearing a noise that I thought was valves/rockers. Breaking out my stethoscope, It's clearly the timing chain. Specifically down by the lower sprocket/oiler. Post rebuild I had great oil pressure. I have not checked it since, but I'll do that tonight for sure. I've popped off the valve cover and looked at the chain, everything is tight. I didn't bump the starter to see if it slacked up. I'll do that tonight as well. My guess is that might not be a good test anyway since the tensioner would not have any oil pressure.
Anyone have any thoughts on this? I'm going to put 600+ miles on this engine starting tomorrow.. I'm not too worried because the chain is still tight, and everything is new. If the oil pressure is good, I'm rockin it.
Oil changed 100 miles ago.
