Cracked manifold, worth fixing?

[MAKG]

Might it be worth a drive to Philadelphia for this?

I've been known to drive to Stockton (over 3 hours, one way) if I'm having trouble finding a part. 'Cause that's the best self-service domestic light truck yard I know of. There is a much closer very good full service yard, but it costs three times as much (or more).

You think theres more junkyards near Philthy? Or do mean to Allan's? They're not quite the same. Allan is north, 2.5hrs, Philly is south, 1.5hrs.

Either way, I'm not driving anywhere. Neighbor's BII, neighbor can drive. And I'm sure he'll choose car-part.com over that. I'm just acting as a walking talking Chilton's guide, tool rental, and promoter of peace between father and son.

However, I really do want to go to the yards with Allan but it will be for my personal purposes only. Wifes been saying no for a year or more now. She knows I would come back $500-$1K poorer with shot springs in the Ranger.

I've got a set off of a 92 4.0L if they are any good to you you can have for the price of shipping. The mating surfaces are pretty rust tho.

Do you know if they work on a 2.9? The rust doesn't matter because we're using gaskets.

I tried gaskets on a 2.9L once and they only lasted about two months before they burned out and started leaking.

I have a set of 2.9 gaskets i will check and see if they will work for the 4.0 manifold

If this is an older vehicle, get a good manifold from the junkyard. It's not very expensive and a dang sight less work.

Yes, or maybe buy one from the bb here. That fix it in a packet isn't going to last, chances are.

Sorry your junkyard sucks so bad, look for a better one.

While I agree with this general consensus, I don't think its informed on any of our parts. I thought windshield repair kits were junk too until I found one that pushes the glue in by force instead of gravity. My neighbor is currently leaning towards trying it.

Ya pays your money and ya takes yer chances. Sometimes the cheap way out works and sometimes you do the fix twice.

It can be welded but it will require a lot of prep.

First you need to drill a SMALL hole at each end of the crack. Then heat the manifold up
and peen the crack. Then wire brush the area to be welded. Take your electrodes for welding cast and do it up. If you do it right it will not fail. Good Luck

Ditto. I did one a year ago on a Dodge Dakota and it's still leak free today. Cleaned the hell out of it and sprayed it down with brake clean to degrease it. Drilled a small hole at each end, filed the crack into a small grove, heated it to about 400 degrees and layed into to it with a mig welder. I had all of 20 mintues into it compared to buying a $100 manifold.
