Oil Pump ? I'm Not So Sure. But I do concure something executed an "Unauthorized Rapid Disassembly". Looking at the larger curled bronze pieces resembles that of Valve Guides. Something became overstressed real quick. I am very curious of your further investigation results.

 

Just main bearings due to lack of oil pressure, caused by loss of 2 qts of oil and left hand turns, I noticed drops down to 20psi in left turns.

With that said, I'm now looking for a good h23 crank. I have 2 h22a1 cranks to trade.

 

 

Wow. I am so sorry to see an engine hurting so, but I'm not so overly confident thats the full extent of your damage, as the shavings and pieces in the oilpan are more than babit bearing material. I would advise not to limit this to a crank and bearings renewal, rather consider a full overhaul.

 

Ouch!

My first thought was valve guides as well from the loom of some of those bits in there, but curled bearing material may explain it as well.

I would assume you are doing a full rebuild to ensure everything else is in good shape, and all contamination from this event is cleaned out?


From what I have found, it is usually easier to find someone selling a complete H23A1 or at least the shortblock, than to just find the crank. Might do this myself, as I buggered up the pulley bolt threads a bit installing my ATI damper.

 

Yea, a complete tear down, cleaning and inspection is in order.

 

Prolly going to throw an f20b in it so I can get back out on track for the time being... It's gonna be painfully slow. Maybe it will make me a better driver.
