Thread: first run after rebuild

Tweet

If you have had the engine running for a while you may see metal in the oil upon draining. Look for those tell tail greyish silver streaks or maybe some very small metal fragments in the drain pan. A magnet is very helpful here if you have one. Run your magnet around in the pan to see if it picks up anything. Moly prelube from the cam can look like metal in the oil so the magnet will confirm it. Unless you have a catastrophic failure such as a broken rod bolt you won't see any damage until you disassemble the entire engine and look at the bearings. Hope this help!

Also cant you look at the spark plugs for little metal fragments,with a magnifier glass and see the rusults of detonation,or does that take miles and miles ?

You won't see that until the pistons begin to disassemble themselves and he may not have run the motor hard enough to get there yet.

I hoped to find something obvious, but...this...
well...I'm lucky that, besides leaving some scratchmarks on the counterweights, there wasn't any other damage done to the bottom-end, because, seeing this, I realise it could have ended much worse!

The other thing I found...a little bit of water in the oilpan, mmm...it looks like it came inside through the distributer shaft...
I'm having a closer look into that this week.
grtz,
