spun rod bearing

TONY! · 02-08-2006, 07:13 PM

I can't see how it is possible to have a good connecting rod after it has had a bearing spin inside of it.
I know that the Toyota bearings (OEM) are made up of different layers of metal, but the outside of the bearings is iron, if I am not mistaken.
Some aftermarket bearings are all aluminum.

Back to the OEM type, if those ever spun, I would bet my money that they did do some damage to the rod, and a good chance that the crank may need to be cut also.

my spun bearing ruined my rod and skuffed up the crank. the crank is regrindable but chances are youll have to get a new rod. Im also debating wether to rebuild mine or replace it with a jdm motor.

I took some pictures to help people see why I believe what I do.

Here are two rods: One in good shape and one that is not good.

Compare the difference:

I have to make a part 2 post because I exceeded my limit...

& More comparo pics:

I would conclude that if one were to have rod knock, they need to get that whole motor out and fix it that way. I can't see how just changing bearings will fix the problem.

Hope that helps people do things the only way I see being fixed properly.
