Help-49C has water in the oil

I didn"t find any cracks in the head or block, but when I fired it back up and ran for 5 min, I already had water in the oil.

Anyone have any idea what I missed? What are the most common areas to have water get into the motor. Where should I look for cracks? Anything I can do about it, short of getting a new block?

Thanks in advance for the help.

You see, all the ac gas blocks from WD-45, on back tend to crack between the sleeves and it is not a mechanical problem, it just lets some coolant get in the oil..

Just flush the water jacket out until it has no dirt and get it dry and hose in enough Permatex to coat the Entire water jacket bottom.. let it flow all the way around the sleeves and you won't ever have a leak there again..problem gone for ever...! Ron.

Sounds to me that you have water getting past the orings on the bottom of the sleeves. Did these get looked at or changed when it was down?

that is what I would be looking at happy holidyas

How do you repair this?

Thanks.
