Rod Bearing problem, My car knocks....and my mechanic said i spun the rod bearing.. Options

[BeefyT]

I starved my engine of oil and now i spun my rod bearing ....does anybody know how much or what u have to do to fix it?

The bearing shouldn't be that expensive.
You can order them singly from Toyota, somewhere around $20 each IIRC?
You'll also have to get
exhaust gasket
FIPG [sealant for your oil pan]

Total parts anywhere from say $40 - $60 [VERY rough guess]

Labor I would guess to be 2 - 3 hours x whatever the labor rate of the shop is.

2-3 hrs to replace a piston rod bearing Jeremy??

I don't know about you but if I were to change out a rod bearing I'd have to either take the head off or the crank out to get the piston out. And if you're only taking out one piston it's easier to just take the head off so the other pistons have something to stay connected to. but if you're going through all that you may as well do them all, and since you're going that far into the engine you may as well rebuild the whole thing.

the Toyota dealer I work at, that is definitely not a 2-3 hr job. just pulling the head off pays about 6-8hrs of labor.

The bearing is FULLY replaceable as long as the crank isn't scored and the rod is undamaged.
If it JUST started knocking there's a good chance the crank and rod are ok, situation depending.
You can drop the pan and inspect for relatively little money.
Saves the hassle and $$$ if they are ok.
It's not a guaranteed fix, but it's doable, and rather common [or used to be before labor got as expensive as it is now].

Not piston rod bearing, connecting rod bearing.
Drop whatever is in the way of the pan, drop the pan, remove bearing cap, inspect crank journal and rod, replace bearing if both surfaces are good, reseal pan, reinstall whatever was in the way.

yes, piston connecting rod Jeremy, I'm talking about the same thing you are.

I figured you would come up with some crazy way to do it. But if you spun a rod bearing chances are it's not just the bottom one on the cap. so you would still need to push the piston up and get to the other bearing that goes on the rod side itself. and I can see how cutting corners like that would potentially cause way more of a hassle than it's worth. and I can tell you if you went to a Toyota dealer, there is no way in hell they would do it that way. and if you're taking it anywhere else (like a PepBoys or something) to do that kind of job, good luck having your car run again. Jeremy's idea is a better way to check the condition of the crank yourself and try to replace that one bearing yourself that way.

Point being to whoever started this thread, it's time to either get a used engine and drop it in or rebuild this one yourself. It's not as hard as it sounds.
