Ok 318la. Has 8-10* of slop in the timing chain. Try just replacing it and maybe eat the time and gaskets if that doesnt get it running or tear it down for a possible re-ring/seal job or worst case senario total rebuild?
Opinions?
Needs a chain and gears. Can you do a compression test or a leakdown? That will help you decide. It won't tell you how far the bearings are gone though. I would tear it down. A re-ring, bearings and gaskets may be all it needs.
