    With the way the previous owner "fixed" this car, the worn bearings don't surprise me. He probably ran it hot and never changed the oil... Or just never changed the oil at all.

    You need the instalation tool for the rear main. The main bearings are shot what did the rods look like??

    Thanks Joe. I have not looked at the rod bearings yet, perhaps tonight. I just couldn't take any more bad news after seeing those mains last night I picked up some plastigage, so we will see how bad it is.

    Might as well rebuild her. I can find out about the cost for a crank for you.

    Ugh! All I wanted was new head gaskets... LOL

    Here is the #8 lower Rod bearing... I only pulled that one... Just in case you guys thought I could get away with it...???



    The plastigage showed it to be in the "good" range... .0015 inch... They look scored, but are very smooth, unlike the mains...

    My understanding is that the rod bearings have a tendency to lose there shape on the bottom end when you re-assemble. Be sure to check them (for roundness).

    The main bearing journals are a bit scored, but the one rod bearing journal I exposed looked very good. Vincent, why did you put that in my head?

    What should I do? Can I polish the main journals and be okay? If I run my fingernail across it I can definitely feel where it is dug.

    Are you saying if the plasti-gage looks okay I should be able to re-use them? How do I check for roundness?

    If I had pulled a main and rod bearing out of that engine and seen the same wear/dirt patten, gotten the same results with Plastigage, there would be no hesitation to polish all the journals with crocus cloth and install a new set of stock sized main and rod bearing shells.

    I would not reuse rod bearings if you unbolted the cap. The crush factor on those bearings is too great, and it WILL fail if you reuse it. You will need new rod bolts as well. Try polishing the scored journal as Sub suggested, but I think you may need a new crankshaft if the score is deep enough to catch your fingernail.

    I have a 99 STS with a cracked block that I am replacing with a different engine. If the crank out of my bad engine is still in good shape, you are welcome to it if you decide to go down that road.

    That's a very kind offer. Is your old engine out already? I am over "budget" on this whole project already, so that would be a huge help if I need to get a crank.

    I agree, after sleeping on it, it would be silly to try to reuse the rod bearings now that I have opened one. I actually expected them to be in the same shape as the mains, so I was surprised the one I checked was smooth and tight. I will polish the main journals and plastigage the mains as Sub said. Are the rod bearing bolts dealer-only? I didn't see a listing for them on the Rockauto website.

    Rod bolts are dealer only. Try Rippy or gmpartsgiant.com or gmpartsdirect.com

    The engine is 'halfway' out. The previous owner had headgasket problems and tried to fix it. When he got the heads off, he noticed a crack in the block in between the cylinders. I acquired it at that point since he couldn't spend the money on a new engine.

    I should have it out soon.

    Hey Crest,
    I read on one of your posts that you go through quite a few cars (buying and selling them often). If this is what comes out of your hands and you do this kind of thorough work, it would be a blessing to get one's hands on a car that has been through your hands. Just sayin'.

    Thanks Glenn. I always did pride myself in dealing in top quality cars.

    But if I had to do this kind of work to all the cars I bought and sold I'd have been in the poorhouse long ago. I did more buying and selling in the past than now. This job is strictly a labor of love. A love for the car and a love for learning/gaining experience.

    I dont want to bring up any more work or $$$$ but why not rering it while your in it this deep. If you do rering only use gm rings, I have seen horror stories on here about non gm rings. Did you pull all the rod caps yet?? On mine I used Clevite Bearings from Rock Auto.
