How do these bearings look?

[Midn1ght Driv3r]

These are only pictures of the outer cam bearing, and one mediocre picture of an internal one. Wasn't really sure how to get good detail on them, so I apologize for the crappy photos. Does anyone have tips for taking these pictures? I can run my finger over them and I can't really feel anything knicked.

From what you can make out do they seem okay to reuse?

I'm also going to be posting pictures of my main and connecting rod bearings tomorrow for the same stuff, they hopefully will pick up a little better.

Looks like there is either grit or something right in the center of this one. I don't like the looks of that.

Bearings are cheap, I'd replace them instead of assembling the motor and worrying about them failing on you constantly.

yeah what edsel said.

without mic'n em you cant really tell how good of shape they are, i do see debris embeded into the babit which is its job to keep the debrid from damaging the rest of the surface/journal etc.

problem is i can readily see grit and debris everywhere and its impossible to clean everything and clean the oil passages with those bearings in place...you can try but thats sorta at the "do i care if this much $$$ goes up in smoke" decision.

id say mic the journals and the bearing to see what the clearance is then decide but with how much grit i see in the crevices/etc i personally would want to pull it all apart.

what motor?

It's a 2.8 v6 stock fiero motor. There's not that much power to it, so I figured if getting the block mic'd would be more than a couple hundred, I would just go pick up something a little bigger and better and not waste my time with it

...just the bearings....i can see how you wanna be cheap but cheap is never cheap in the long run...just the tow back home from a blown motor can negate any savings.

it may be worth it to get a good shortblock that you dont need to futz with.

we picked up an 80-100k 03 3400 for 400$ on Clist a year back...the deals are there so at the least keep looking while you toss that motor together...it could be fine but cleaning that grit out would be challenging to say the least.

These connecting rod bearings were supposedly brand new and only ran for a couple seconds before the previous owner swapped the bearings.







I think these are bad...




The destroyed cam journal:


Definitely not sure where I'm going to go now.
