Rod Knock Question

[MasterFrmMO88]

Okay, here we go. My engine recently developed rod knock. It started when I first started up the car and the bearings were dry. I shut it off and haven't driven it since then. I'm hoping that, since it was running that long that the crank didn't get damaged and I'll roll new bearings into it.

Here's my dilemma. I have the oil pan off and saw wear the number three rod is black from the shaved bearing. I pulled the cap on it and now I'm trying to get the bearing off. It's stuck. Best case scenario is that its the capillary action of the oil holding it to the crank. Worst case scenario is that the heat from the engine fused the two bearings together (I dont think this is the case as oil still seeps through the joint in the bearings a little bit) Anyone have any good suggestions as to how I can get the bearing off without damaging the crank?

get a peice of brass and shock the bearings off(strike the brass with a hammer, be wish for a ok journal.

have you tryed turning the motor by hand?

best case scenario now is when you get that bearing off, hopefully you can polish the crank and put in a new bearing. check the clearances tho with some plastigauge. Let us know how it goes.

Turns out the bearing had spun inside the connecting rod mashing the tabs down and those bonded each half of the bearing together. I spun it around to the side of the bearing that didn't have the tabs on it and used a very small flat bladed screw driver to ease them apart (didn't use hardly any pressure getting it in between the halves as I'm really paranoid about ruining the crank, that would be a very bad thing for my daily driver).

Anyway, onto the important part. Got the bearing off and, to my very happy surprise, I have no noticeable grooves on the crankshaft, mostly just some burnt oil. I took a piece of 800 grit cloth and got most of the oil off but I'm afraid to go too far with polishing until I find out the gap clearance. All the plastigage went with my dad to our racing garage which is twenty minutes away so that will have to wait until tomorrow.

Got the plastigage done and its still in factory specs at just over .001" so that's good news. So I'm going to try and put it back together with the new bearings in and see what happens. Can't be any worse than having a car with a disassembled bottom end.
