Cam bearing wear?

[3400-95-Modified]

Should I replace these??

I have the resources to do it myself, I'm just not sure if its necessary...

[Superdave]

eeek.. yes. Deffenetly replace those!

they are not rough in any way they feel completely smooth, but if you say so then I'll do em. I'm just unsure.

The top half is what they look like when they are brand new, only the bottoms show this wear.

the knicks, scratches and little pieces of metal on the right side are pretty bad.. you might want to consider having the block tanked to make sure any of that metal is out of the system.

it's like $30 for the bearings.. pretty cheap.

Um, I dont see any metal, but I know what you mean by the knicks and scratches... As far as tanking the block... this is still a short block with heads on it... i wasnt about to take it that far down.

I think you understand when I say I only have so much money to play with...

I rechecked what your talking about, that looks like an uneven surface that was on the bearing that wore off that way, I couldnt get that piece off the surface and it had no edge really.

More pics 4 angles.

Is that copper showing on the sides? Mine were showing copper on the bottoms so I had them replace, and the block tanked. I wanted all the oil galleies cleaned out. But I did a complete refresh.

Its like a copper color but there is no wear in that area at all, I'm not sure if that was the original color of the bearing in that spot, because right below where that is you can see almost where that color wore off and went back to the typical silver.

Only wear pattern on these is the bottoms how they have marks, and thats probably due to the cam and the LS6 springs.

I popped off cylinder 1 rod cap and those bearings look BRAND new still so I 'm not worried about the lower end at all. Lower slug holes also show no scuffing from the piston skirts so I'm thinking that part is a-ok for now.

well all are out... that was not fun beating on my block with a damn rod and hammer... something so fragile seems to have a rather rough process to install/uninstall them.

[SappySE107]

Yeah, its quite a process to r and r them. Your old bearings didn't look very good to me, and copper color = replace.

[ForcedFirebird]

They were trashed.

Did you replace them with small block bearings (wider than the 60*'s but are the same diameter)?

[3400-95-Modified]

no going back in with stock ones, Also the copper color on them were in the non worn areas... there was only one spot on one of the B bearings that had a slight spot of copper showing through, so I guess its good to do them.

Also going back in seems like it will be mucho easier, install both B's one from front and one from rear and then do the A in the rear and the 1 up front... it was just removing them that was hard... it was like impossible to get them out of the cam area once pounded out, I needed to pull them back through the bores... not easy, till they collapsed a little.

Be careful putting the cam back in. That front bearing had some bad gouges where some monkey had scraped a lobe across it. Don't do that to your new bearings. It can be avoided by taking your time when putting the cam in.

I think that was done coming out, But I could be wrong...

You calling me a monkey!!! LOL
