Engine Clanking -WTF!!!

Oh shit! :( Good luck with everything.

Deffinetly an option man. If the cylinder walls aren't scored You can hone the bitch with a powerdrill and drop in a new piston.

Is it going to be as tight a clearance as the other 3? No, but It'll get you down the road through the summer and then some. Is the rod OK?

I hope much metal didn't make it through your oil pump, turbo, bearings, etc.

Maybe when I get everything cleaned up in there, I'll try and get one of you smarter engine folks over here and take a look, and give me some words of wisdom.

If the cylinder walls don't have any major scoring that your fingernail would catch on, you can rehone it and drop a new piston in there. It really depends on the condition of the cylinder wall. Being that the piston has an actual hole in it, metal fragments are most likely in your pan. If that's the case, than you might be able to get away with honing that cylinder, but if any metal got through the pickup screen and filter and into your bearings, a full rebuild might be best because you'd have to pull the motor anyways. I'll try and find a minute to get up there. Keep me informed on what you find.

Before I saw the findings, I asked my uncle (the most mechanically capable person I know) how or why this would have happened, and he thought something foreign entered the cylinder, piston pushed it against a valve/hit spark plug, then the cam trying to open the stuck valve breaks rocker arm, etc. I wonder if something got in there?

I personally have honed/installed a new piston and ring set into a cylinder with three giant gouges in the thrust side of the wall, probably.050" deep, and the car had 155 compression in that cylinder and didnt use excessive oil.

I sprayed some brake cleaner on the walls real quick and got the walls pretty clean of oil. There are definatly little marks in there. I can feel them with my fingernail. I'm thinking nothing that couldn't get machined out though. But also not sure if a little hone dealy on a drill would get it out though. :(

Hmmm... you live in Shoreview right? You're not all that far from me. Maybe someday if you don't mind, you should stop out here for just a minute and see how my walls compare with the ones you did.

Your best bet is to run a hone through the cyllinder, then re check it. You could possibly get away with just throwing a new piston in that cyllinder (best case scenario) And as others have said, it's prettymuch guaranteed that there's metal shavings in your pan, so you can hope the oil pump didn't pick any of it up

[Halon]

I'll have to take a good look at the oil pan when I pull it off. I didn't think the oil looked too bad when I drained it out. Anything not perfect in it I was kind of blaming that on the old dirty drain pan that I used (should have cleaned it out before hand).

Is there anyway to pump a ton of oil through the motor to try and flush as much of that stuff out of there as possible before cranking her over?

[MustGoFaster]

Dam dude that sucks.

Spin the oil pump with a drill. But I would pull the pan and clean it first. Be sure to put something in place to catch the oil that would be going to the head. But you will still push some oil into the bearings as well.

You can get away with a fair amount on a motor. It may not be the best it can be, but running ok is better than in the garage broken. Be sure to have the rod checked as well.
