Me too. I'm not sure if they bearing could have been badly chewed up from less than 5 minutes of run time, but... Hoping the damage isn't too bad.

I removed everything from the engine last night; she's ready for the engine hoist later tonight haha. I suppose there isn't any sense in ordering new bearings yet until I see what has happened.

IF I had to do it again, I would buy the sleeve specific for my size bore, if not for convenience, then peace of mind that the rings/bore wouldn't be damaged
I second that.

I don't want an aluminum paperweight because I didn't follow the proper documentation. All I know is that the key to a good motor is precision in measurements and torque.

I want to build it properly. Appreciate everyone's guidance on all of this.
You sound like me on my current posts haha

Exactly. See what the damage is and go from there.

Ok - something i've noticed while tearing everything apart... On the driver's side, I stuck my finger into the hollowed out back side of the intake and exhaust cams. I felt little metal slivers in there, but not in the drivers side. Both heads are off.

What is the best way to clean the heads out of all the metal flakes? I don't have a parts washer unfortunately. Is there some way I can clean them out well at home/in garage?

If you have shavings in your heads I would not trust a diy cleaning solution. Have a pro do it.

Last thing you want to do is rebuild it, and having skimped on cleaning, spin another bearing.

This is sound ^^.

Just remember if you can see shavings anywhere where oil flows, you need to disassemble EVERYTHING and have it (heads & block & oil pump) thoroughly cleaned. If you can see it there, just think about the oil galleys that you cant see into that have had shavings pumped through with the oil.

I would also flush AVCS lines and Turbo feed and return lines, oil pan etc. You dont ANY possibility of bearing contamination when you put it back together

Thanks for the advice guys. Ill see what sort of places are around here that can clean it up. Is there a certain cleaning process I should ask for?

There is a thread about disassembling and AVCS cam gears somewhere, you will need to do that too to get the metal out of them. Did you find a spun bearing or the source of the metal yet?

Not yet. Just pulled the wrist poston covers. Pulling the pistons next!

Ok, so this is interesting ...

Check out these photos first I suppose!












It looks like a minor amount of damage to the bearings and crank as far as the mains go ( i'm not an expert of course ).

When I grab the connecting rods by the little end and wiggle side to side, they all move a tiny bit as expected but no clunking etc. When tugging on any of the rods, nothing really feels out of place. They all have the same tiny amount of play.

I'll remove the rods from the crank and take a look next... So far I haven't really seen the culprit?

Oh... And I read about this trick in the "tricks of the trade" thread, and dang it worked SO WELL. The wrist pistons glide out like nobody's business, and you don't scrape up the inside of the pin, etc.

been following your thread for a bit now. sorry for the luck. makes me a little more cautious about doing this whole process myself in a few weeks. good luck in getting it going again soon. about the oil priming bit......have you checked to see if the turbo sent anything through there? I've always read that you should wait for oil to come out of the oil feed hose to the turbo because that is the point furthest from the pump in the oiling system. seems like you did everything right in re-reading your thread. just guessing and trying to throw something else out there that may be worth taking a look at.

Yeah, im hoping to identify if there simply wasnt enough oil pressure on initial start or what. None of the bearings spun, but bearings are scuffed up a bit...

Or... there could have been metal hidden all up in the heads after machine work. Posting pictures of rod bearings soon

Looks like oil starvation to me. Maybe oil pump did not wk or maybe no oil on rod bearings on start up. Did u use oil or engine assembly lube on rod bearings?

red line assembly lube or the bearings. Applied liberally.

I was watching a YOUTUBE video and Subaru master tech used motor oil. I have no idea if that matters or not bit it looks like bearings did not get oil in a timely matter.
