Engine messed up. Replace or rebuild?

[old man jimmy]

Sorry, I miss read you statement. I thought you lost oil pressure.. Did he by any chance tell you your motor was "out of time?" if so you're timing chain may have jumped a link from the jolt. I guess I got the "no oil" in my head from your earlier post about no oil to the rockers. The chain should be in good shape if it was rebuilt 30k ago. I can't imagine anybody building a motor and not replacing the chain and gears. The original cam gear had nylon coated teeth, and they got brittle and broke apart with age. Everything is just a guess, can't tell much without checking it out. But back to you're original question. If he wants 800. to fix it. I would go with a crate 350. Last one I got was around a grand, and had 3 yr. guarentee.
