So I just got my 408 iron block back from the machine shop last week, i decided to lift it up today to put my ls1 oil pan deflector/ windage tray (i've heard it called both) on ( it isn't fitting right which is another problem...). well, long story short, this is what i found laying right near where the reluctor wheel sits:

it can't fall out of a installed cap and rod. it was either in the bag, or stuck to somthing and fell off? Is it missing form any any rods, any one of them more loose?

so should i just go try to shake every connecting rod? doesn't cam bearings look just like it? it wasn't in the bag, i put that new trash bag over it the first day i got it back and had it sitting. i tried to look at the rods, but i just couldn't see anything but red heat from being so pissed that i paid nearly 1K for this assembly.

cam bearings are solid circles. not two pieces like a rod bearing. It is possible during engine assembly a bearing fell out then the builder torqued the cap down and didn't notice it. However, I would think they would notice when they turned the engine over. Put a socket on the crankshaft and rock the crank back and forth. You should be able to hear if one bearing is out.

I'd try to move the rods around, or spin the motor over and listen for a clunk. Cam bearings are round, they wont just fall and hit the ground.

lol thanks guys, I will try to fool around with it in the morning. How many cam bearings should there be? I will check to see how many are left that the builders took out of the block when they built it and see how many i'm missing.

There are either 5 or 6 cam bearings but that isn't a cam bearing. It's def a rod bearing. I would start there instead. This is the reason I build my own ****!! Not trying to be a dick but a well known sponser on this site screwed up my car big time and wouldn't take ownership of the damage!! Instead they JB welded where they snapped off the nipple from the radiator instead of replacing it. Not to mention crossing over to coolant lines. Between the 2 things it caused my $8000.00 build to over heat and blow the motor!!

oops sorry i meant rod bearings/

ouch! man that sucks, i'm not willing to risk continuing to get this block mounted until i'm sure it wasn't a bearing from in the car. I just know i didn't sit the block down on top of a bearing. and it was submerged in oil too.

WTF damn. I'd be having words with that machine shop, make them disassemble the **** to check. It's not like there are extra bearings in the sets.

Bring it back to who built it, have them inspect it and give you some sort of written warranty.

What's the part number and brand of the bearing shell youve found?

check all the rods.

When i assemble a motor i always have an extra rod bearing pair. I mic it and use it to check bearing clearance and torque the rod the bolts the 1st time. All so i dont damage the actual bearing im going to leave in the motor. Your builder also may employ the same process and dropped the extra and over looked it. But leaving it in..... not so good as far as quality control.

I can not rremember what part number the bearings are, they came with the new TSP 408 rotating assembly i bought. It looks like the edges of the bearing are scratched a little bit. how can this happen already? i haven't even turned the crank by hand. I got the block from the shop and loaded it into a pickup, when i got to my house, it was loaded off the truck via enigine lift, and sat down in my garage on top of a cardboard box and wrapped in a trash bag ever since. now that i remember, after i posted a thread about a freeze plug being on the block, i tried to tap up with a socket and pulley type system to fit in the small space, and the socket fell through. it made it's way clear to the ground and i saw nothing when i picked it up. then again i didn't have to pick the block up to get it. a socket shouldn't be able to knock a bearing out should it?

also, i shook the rods and they all felt the same as far as stability. honestly, i don't know what the hell i'm looking for. I'd hate to have to take a 2 hour drive to drop the block off again for nothing. but stuff shouldn't be falling out of a block thats potentially going to make 900-1000hp.

if a rod bearing is missing in the rod there will be tons of play and be obvious even to someone who isnt experieced.... move each rod up and down left to right and just make sure there is no play. i think i would make those guys come out to your garage and verify everything is ok for you. although if you start it and there is a bearing missing thank them for the new motor they're going to buy you and be sure to go bigger cubes.

no a socket couldnt knock a bearing out.

IMO if you are assembling this yourself and don't know if youre missing something, don't you think you should probably consult with someone locally, not just rambling about random 'what-ifs' on the interwebs?

This video should help you out this lt1 has a spun bearing so if you are missing one it should make the same sound but even louder. I'm not trying to be a dick so i apologize in advance but who is assembling the rest of the engine? If you arent sure how many rod bearings your engine has and how to to check to make sure they're all there maybe you should let someone finish the motor for you...
