I have an option to buy a 4bt with a 4 speed bread van. Thing is the engine has a knock. The guy wants $850 for the VAN. How much would it cost me to rebuild this thing on my own with all CUMMINS parts. Im not in a hurry to get the engine together or anything so down time isnt an issue. Also where could I get the parts? Im not sure what is wrong with the engine so give me a few scenarios please. I have not heard it run all he told me was it had a knock.

Thanks in advance.

Try google or ripbay

Rebuild kits are around a 1400 bucks in canada and more than likely half that in the states.
If it is a pin knocking you should have an easy fix. If it is the crank - you need to add in the cost on having the crank turned.
850 is a decent price if the block is not a total pile of pooh.

It's really hard to say,but i have spent over $5000.00 on overhauling my 4BT which i used aftermarket parts where ever i could.It probably could have been cheaper just to use it as a core and get a rebuild from Cummins.

I would highly recommend just finding a better engine. Your time is money, and after you throw new parts at it, you would be better off finding a better or new engine.

The lure of buying something cheap, and fixing it up for little money is a myth. I wished I would have just bought a better engine first, then I would be money ahead.

Hard to say ,take a chance and see what you get .The worst case you have extra parts .

Aluminum body?

$850?

you'll get that back in scrap. at the least you'll have parts, as stated. If you have space for an engine-tranny.

I think you should just tell me where the van is located. I need the flywheel. It will cost you $billions to rebuild it.:D

Seriously, if you are looking to build it, you can easily make that money back in scrap cash.

I'll drive right to VA for the flywheel....

Rebuild kits are commonly a little over $500. Pretty stout crank, not likely in need of turning.

Never know: if it's a guy that knows nothing about diesels he might think it has a knock but just doesn't know what a 4bt sounds like!

Gotta agree with what's been said here. At $850 you'd be able to scrap the body / frame and probably make a profit.

I think JimmieD might have something there..

Unless you're familiar with diesels, and specifically with these B series Cummins, you'd think the thing is coming unglued if you were comparing it to say a Duramax or Powerstroke or even older indirect injection engines.

If it's not too far from the house, I'd say go and take a listen. May be purring like a kitten and the current owner doesn't realize it.

I agree with Machman. Go start it. It might run great. Just say 'yeh, this thing is hammering like the hounds of hell, I'll guess I could give you $500 for scrap' Then drive it home.

$850 for the scrap alluminum? What are you guys getting per pound for the alluminum? Sounds a bit high to me?

I don't know what it's going for in your area, but folks in the past have been able to get over $1K for the scrap metal in the vans.

Of course, your mileage may vary, not to be taken internally, externally, or existentially, this post AS IS..

Buying a van for cheap and cutting it up for scrap is a bit of work and often times you can sell them complete without engine for considerably more than scrap price. Price per pound anyone? Your dollar amounts seem high???

Cleaned sheet is bring .60 a pound in Youngstown.

I wouldn't doubt theres 1500 to 2500 pounds of aluminum there. 2000 pounds would get 1200 bucks :D

Cars are bringing 240 a ton right now. :eek: makes it hard to buy a used cheap car

Those things can have fuel knock as well, which is a fairly cheap fix so long as there is no damage to the pistons. Those engines are pretty solid and it could have nothing more than a bad injector. You could do a tear down if you have the time and check it all out. Worst case is you have to rebuild and best case is it is perfectly fine and you put a new set of gaskets and injectors then go 200K miles.
