Fresh rebuild crank won’t turn after installing in truck. (2 Viewers)

@Fj80oregon So is the spun bearing the fundamental cause of the failure or a symptom of some other issue? Lots said about oil pump and priming and I kind of agree with @cruisermatt that the oil pump wasn't the issue but is a random bearing spinning for no reason likely?

Some years ago there was a Mud member who had a new short block that suffered some sort of serious engine damage shortly after start-up. IIRC @cruiserdan was able to get a warranty replacement short block for that customer. FWIW

I don’t know for sure. The bearing spinning is for sure the failure just don’t know what caused it. Even the spun bearing had oil on it along with crank journal. Going to talk with Toyota, all the other bearings had plenty of oil so its just odd that one decided to spin. I have seen severely neglected engines with lots of wear on all bearings, piston skirts and cylinder bores and they still ran relatively well and spun freely.

Wow that is a genuinely large amount of damage.

Any updates?

Update from Toyota?

New block inbound! Toyota agreed something failed, either the oil journal was clogged in #7 or a piece of debris from machining got into the journal. If other bearings were damaged or any other damage was done then it would be on me. Thankfully Toyota stands behind their product and was very accommodating. Now just have to wait for one to land in the USA.

Solid. Glad it worked out.

Onward.

Will you change your mind and do the supercharger again?

Not sure have a couple rebuilds going on and a whole turbo set up to put on a truck so I might put it on this green truck and try the turbo route.

Looks really good.
1) does it turn?
2) assuming it does turn - I'd still lube the b-jesus out of it!!!

I'm mostly teasing you; you are my rebuilding HERO!
GOOD LUCK!
