it made weird sounds and the oil pressure was really low. It sounded like the bottom end came apart. but I took apart the top end of the motor and everything was good looking, nothing was damaged so I guess Im gonna take everything else apart tommorrow. Any ideas on what it is, any suggestions?

 

It probably ate a bearing

 

rod or main? because that was my first thought, Im going to pull the motor this week and find out but after it sounded like hell in the block, it starts right up and idles with the ms4 cam so I have no idea. but has anything like this happened to anyone else?

 

Mine sounded like a monkey with a stick and a coffee can. It turned out to be #5 and #6 rod bearings toasted and took the crank with it

 

damn that sounds bad, I shure as hell hope the bearings didnt take my crank with them as well. if so **** it im goin bigger cubes.

 

rod bearing......mine sounded like something loose flopping around in the bottom end

 

seeing if my sig pic works

 

are rod bearings expensive?

 

the part isn't expensive but you have to take apart your motor to get to them...thats when it becomes expensive

 

federal mogul are only like 35.00
labor about 1000.00
do it yourself

 

so as long as you tear the motor down yourself its not really that expensive right? Sorry to hijack the thread. This is my last question here. Just figured the OP might want to know this stuff too

 

I ate up number 5 and 6 and 1/2 3/4 were pretty close to the same.

 

i smoked 1/2 7/8 others were fine

your oil should also look like metallic paint

 

Seems like Ls1’s are bad about eating bearings for some reason. Friend of mine’s ls1 just ate one for breakfast. (not sure what cyl)

 

The big issue is after pulling the engine, and even after you break it down is to inspect and then check clearances and make sure its with in recommended servicing specifications.

I.E. checking the crank and making sure if it needs to be cut, polished, or if its fine. And that if you have to put a oversized bearing, generally a machine shop will do all of them to keep it simple and for future servicing.

Yank it and check it, fix if needed,
