Thread: 426 Hemi Oil In Water

Tweet

There is an oil passage that takes oil to the rockers. I doubt that's what's causing the problem, but it's just possible.
If it runs well, you could try waterglass in the rad. Flathead Jack sells it for cracked Flatties. I have used it with good results on freeze-cracked engines, though nothing high performance. It might not hold up to the stresses a Hemi could put on it.

Kurt, I understand with what you are saying, and usually would agree, but this is an orginal Hemi car from 1966. It then becomes a whole new ball game because of the worth of those number matching Mopar's. The internals of the engine are easily replaced and at no disadvantage. The block however is the verifible part of this equation. If and that may be a very big "IF" it can be saved it should be simply because it add's so much value to the car.

I know severeal folks with original Hemi cars, a couple of Chargers and a Road Runner or two. I personaly have a Hemi Cuda. Some of these folks and I include myself in that some, like to drive our cars. The number matching engine means so much as to value of these cars that some folks pull out the orginal Hemi and replace it with a Mopar Performance 426 to do that driving, store the orginal Hemi until they decide to sell. Seems like a lot of trouble but when you are talking about a motor worth as a number's matching engine for a Hemi Charger you are talking $25,000 to $75,000 dollars worth of value just in the motor alone. Yea you need to save one if you can.
