Thread: 426 Hemi Oil In Water

Tweet

Gymbo; I would tear that thing down and take a real good look at it.
I don't know how old that motor is not only that If there was no Anti-
Freez in it. The head head gasget could be gone too.
That's where I would look first before thinking the worst.
It's just like Pope said but I would give it a good looking at.
I used to play with the big block dodges back in the day,
but they started getting to expensive for me.
If the block is cracked I wouldn't even mess with it.
Save what you can and toss the block.
We had several 426 hemi's that we tried to have
fixed or welded and all of them would just crack again.

i diddnt think a head gasket could cause oil in the water. how could it? is there oil galleries in the head? i thhought the oil went up top via push rods. i dont have much experience in hemis so please forgive me. i will look at the head gaskets.
Thanks,

While you will need to look at ever possiblity, I wouldn't think your problem is caused by a head gasket. There also are more ways other than welding to fix a cracked block. If that is the problem.

With the price of orginal Hemi cars going through the roof, and if this is the orginal Hemi block the last thing in the world you want to do is throw it away. Any number matching Hemi, that is all numbers orginal to the car, is worth 10's of thousands more with the correct block.

The first thing is to determine were the problem is. Then and only then can you make a choice on __How to TRY and fix it. Welding is one way but it is only one way. Good luck!!

Kurt, you can't be serious, toss a Hemi block??? I agree with Roland 110%, especially if this is a numbers matching engine block, only a fool would toss it. If it isn't cracked in a 'load bearing' place, it can be usually be saved. I used to own and race numerous Hemi cars in my younger days, I've seen Hemi blocks with holes punched in the side from broken rods that have been repaired and used again.

Gymbo, the first thing you've got to do is disassemble the engine carefully to locate the source of the leak. If necessary, have the oil passages pressure checked to locate the leak. If this is a numbers matching block, take Roland's advice, do whatever it takes to save it.
