i just picked up a 99 ls1 block, guy told me it had a spun bearing, got it apart today and it did.. #8 rod bearing and #4 main bearing spun .. block looks good. still needs specd out but crank on #8 rod is f*ck up... i have some pics, and i get some advice please...thanks for your time

 

Should be able to turn the crank .010 under but have your machinist inspect the block

 

Yep crank can be turned down and polished.

 

cool thanks for the help... any idea what machine works gonna run..

 

How long is a piece of rope?

Answer this question correctly, and we'll tell you how much your local machine shop charges for labor.

 

Yeah crank needs to be turned and I would have the block checked to make sure its still good. Price is going to depend on where you take it.

 

thanks dick... if i wanted a smart *** answer i would have asked for one... could have said something like below but had to be an *** about it.. its ok thats what i get for asking

thanks for your help...

 

Welcome to LS1tech. Don't take it personally, you get good answers here, sometimes folks are going for a joke or making a point. Harm is generally not intended.

 

I know i jus read ppls comments like that all the time, first one i have got... just gets old... i kinda understand where he is coming from there is alot of stupid questions with easy answers.. i was jus looking for a quick guess-tament from someone who has had similar work done before...

 

You'll want to grow thicker skin, or learn how to spell and communicate.

 

Oh no he didnt!! HA!

Classic advice for the boards, I personally was moved by the rope question!

Seriously though, machine work in Oklahoma City is cheaper than New York plus the chics have bigger ****. Call your local machine shop for a quote. If your in Oklahoma I would suggest Folks Machine shop in Norman, OK.

might want to find the cause of the spun bearing as well

lack of oil?
lack of servicing?
excessive heat?
failed oil pump?
failed relief springs?

additionally if these bearings are spun check tolerances and condition of the rest of the motor

 

That's it, I'm moving to OKC!

 

Thanks.. im gonna guess lack of oil maybe... by some means bc cam bearings aren't the prettiest... didnt come with cam/oil pump.. only lifters and rotating assembly...

 

probably a good thing they aren't included, at least you know the condition of parts you put into the motor

 

That's a good bit of info. I'd speculate that the prior owner botched a cam install and/or installed the oil pump wrong which caused the bearing failure.

Make sure the oil passages in the block get flushed out thoroughly.

 

the guy i got it from said it had an aftermarket cam in it... he pulled it out and put it in his car... good idea prolly not but.. not mine.. did come with a rollmaster double roller timing set.. doesnt look used at all and 2 spacer shims for the oil pump.. wondering if they had something to do with it, btw sry about yesterday had a shitty day wasnt in a good mood...
