S.O.S

Well the Kroil would not free them up so I finally broke out the hack saw. Sure enough, a leak about half way down.

I'm sure I'll find plenty of good uses for the Kroil.

I sent an email off to your guys at Crow to enquirer about price and time line. I suspect the location of the crack is unreachable to the typical welder?

Now, before I spend money on repairs I guess I need to think about a few things like....

Is the cost of the repair worth repairing or do I spend money on new ones, or find some good used ones?

Do I check out the rest of the engine before I spend any money at all on the manifold? I can always pull the intake without any real money loss.

I would wait on the intake, it was fine until it got hot.

you ran it in the drive long before you but it in the water, and if the oil looked good before the on water test then I doubt the intake is an issue.

Dave get on here and ask if someone has any,someone just sold a pair for 100.00. Would not hurt to ask

These look quite a bit different than mine. Wonder if they would work?

Dave,
I spotted those manifolds on ebay too. They may have come off a H/M engine but are not the same. They look more like Edlebrocks.

Definitely not the same. I do have a lead on some. Contacted the guy selling that previously mentioned HM engine on ebay. He claims to have some. BTW, he wants $2,500 for that engine. Sounds a bit steep to me.

Sorry Dave! just got your message, give me a ring 269 506 1249 Jeff

David,
I would put both manifolds on you're getting from Jeff. With the loss of cooling water and the burn through on the one side, you don't want to take the chance that the other side is ready to go as well.

When you get the manifolds, take a look at the mating surface condition (riser elbows too). Then take a flat file to them and see how well they clean up.
EDIT: Besides the gaskets, I'd get some Permatex non hardening #2 "form-a-gasket" on both sides. I would not use RTV on them.

Considering the cost is pretty low on engine/manifold gaskets, I'd go with new ones.

David,
The outside is easy with a scissors but inside holes get harder the smaller they get. For round holes for bolts a gasket/leather punch works great but in a pinch, get a small pipe nipple. 3/8 pipe works for 3/8 bolts great. Grind the end to a sharp edge, place the gasket on a block of wood, center the pipe nipple over the hole you want to punch and wack it!!! Now, you have the oval shaped water jacket holes - I'd hole punch the ends and then cut hole to hole with the scissors. Clean up on rough inside edges I use a small sanding drum in the Dremel.

David,
With the exception of the outside of the gasket, all the holes inside can't be traced. You're going to have to get the kid's compass out and do some layout work! Lay out one, cut it and if it fits then use it as a template for the second.

Are you going to change out both manifolds right away?

Thought I would keep y'all updated.

I'm at a standstill again. Never received the manifolds Jeff was going to send me and I can't seem to get a hold of him. Not bad-mouthing him mind you, he could be out of the country or something for all I know.

I was shooting for getting the Mustang back on the water by the 4th. Not sure where to go from here. Do I spend $500 to have the Crow guy restore the cracked one? That sounds OK but what if the problem is deeper, then I just spent $500 on one manifold I can't use. And for that price it almost makes sense to buy two new ones, but them they would not be the cool HM ones.

This guy still has these for sale,
manifolds
I asked him for more info and pics. They do look like Edelbrocks but the logo on top almost looks like it says HM. Not even sure if they would work. Don't know how much he wants for them either. He asked me what I would give for them.

Anyway, before I would spend $500 or more on manifolds I would pop off that intake and hope it's the water in oil problem. If it looks OK then I would probably not spend any real money on manifolds for fear of deeper problems.

Don't see why not.Not sure how the water hooks up,there must be another fitting on that front cover. Pete would know how to connect them up. New ones are $640.

These have relisted as well.

They are apparently HM.
