I'd just take it down all the way and clean it up from there.
It's probably it great shape overall, but I can't imagine leaving some of that dirt/grime inside the engine.
Good luck

Just finished disassembling an 80k mile 5.3. Looked very nice on the outside.
Was replaced because of white goo under pass side head.

The pan had at least 2" of grey/black paste in the sump. There was a divot where the pickup sat. Ha!
Glop came out of the filter. Sludge city under the valley cover.
Rod and main bearings were perfect! Bored excellent. Pistons fine.
Amazing.
I saw evidence of a weeping head gasket. Cam bearings pitted.

Will go back together with a few new gaskets, LS1 cam and a turbo.

That is crazy that none of the rod bearings had an issue.


I was going to pull the heads and check the cylinder walls. If they look good. I was going to leave the rod and main bearings in place.

This motor isn't really sludgy it just had a layer of mud on it and in the valley cover. The truck it came out of was a railroad truck. Strictly dirt road driving only

One thing that is kind of weird is that the front (the first three)rockers and push rods have a layer of rust on them. Any ideas what would cause that? I'm assuming pressure washing without covering things.

from your previous post, you went from "I bought it from a guy.. No yard to take it to. He is going to refund me some of the money" to "true scumbag".

Can we assume that the seller decided to not refund any of the money at this point? Or did something else happen to lower the sellers status?

Yep, no money for me. He decided there were way too many "variables". To be fair I have had the motor for a month and half. I work out of town a lot and have two small kids, so time is tight. I has been stored in my garage on a stand since the day I got it. He went from it ran well in his ad and was maintained well to how was I supposed to know it was bad. He also said he gave me a fair price. I agree if the motor was what he said it was. It would have been an awesome price There is no way that motor ran well with the rust in the cylinders like that. The head gaskets slid off in one piece, so I think both of them were leaking. I cleaned the cylinders out with blue shop towel and WD40. It looks a little more promising than earlier pics but it will need some machine work I'm sure
Oh well. Lesson learned

I know if has been a while since I have posted on this.

I have been tearing the motor down and the bottom end looks perfect. The bearings look new. The crank looks perfect also.







Once cleaning all of the mud out of the cylinder walls. I think I might be able to do a quick ball hone job. I'm going to have the block hot tanked etc and see where I'm at after that

whispers....403...408.....time..

I picked up my short block for $200 from an auto salvage. At first it was $300 till I tried turning the crank over in front of them and then it dropped to $200. I got it home knowing it was going to be torn into anyways. Pulled the pan and windage tray and found #8 piston rod looked like a pretzel. I figure it had been from a hydrolock. So I had my machine shop look it over and had them bore them out to 4.005" I was in a hurry at the time and trying to get it back together. Long story short...on test drive I had rod bolt failure and it ate the crank and several bearings. Lucky my cam survived. So it's now a 403ci.

I never went any further with it. I was half temped to hone it and throw it back together. It is still in my garage. I have everything I need for the swap
It is supposed to go in my 95 caprice wagon that lost its built 4l60e today.
Not sure what my next plan is. I travel for work a ton and have smaller kids. I just haven't had a lot of time.

I'm not giving up on this thing quite yet. I ran a ball hone through it(400 grit) last night and cleaned up well I think I'm going to slam it together and run it. I can drag a fingernail and nothing catches.
