The new turbos don't look very new

DixonM · Aug 7, 2022

Looks like painted up old turbos to me. They didn't even replace the turbo drain pipe it is rusty and has some oil residue on it if i were rebuilding the motor and installing different turbos I would have changed that out to eliminate one more possible leak or failure.

What causes them to pit like that? Wintertime metal etching road surface spray? I got a Cat reman for my 3126B and other then the tag on it and the scars on the paint from them throwing it in the box still wet it looked close to new. Could tell the iron exhaust side was used.
As far as the manifold nuts and studs are concerned maybe those guys have a trade secret and found out that is the way to keep them from breaking like usual.

I’d me more pissed they got yellow paint on my black frame or anything else that should not have overspray on it because masking it off was to hard for them. But that’s the details person I am. Lol!

Looks like they used 10x more paint on every surface than the mcallister cat rebuild i had done did for mine 6+ years ago. They didnt bother to clean anything up so any paint they used stayed there by dumb luck, mine almost looks everything is just barely oversprayed

I'm working on the truck now (replacing the batteries) and I took some more photos of the turbos and the manifold studs.

First 2 photos are the top turbo. 3rd photo is the bottom. And a more close up of the studs. Can someone tell how can the manifold nuts be fixed? Do the studs need to be replaced? Were they simply driven to far in?

I don't know anything about CAT motors. What gets me is some of the yellow left on the bottom of the turbo in your first pic.

And the silver over spray on the yellow inlet.

Just sayin.

So are they good or should I run them for a while and replace them with better turbos in the near future? I was looking into those BullyDog or PTI turbos. Want more power out of it, since I currently have Cat's lowest tune - 435hp.

As far as over spray, I'm not really concerned. It's an ugly 9400, not a show truck by any means. Plus it's underneath the hood. Some time in the future, I'll take my truck to a body shop for a frame restoration and I'll ask them to cover that up. There's a shop I know in Jeffersonville IN, across the river from Louisville that specializes in frame restorations of heavy vehicles.

If you want more power there is no reason to change turbos. That compound setup can handle 700-800 easily. Just need more fuel

So the question of the turbos has been settled - reman Garrett's, I'll run them.

I'm glad you guys brought up the studs issue. I'm talking with the shop about that now.

I am mechanically inclined but not a mechanic by any means. So maybe there's something else I missed. I've added another photo from the other side, maybe you guys can spot other issues that need attention while I'm still off duty.
