Chocolate Milk Coolant.

Check the tranny oil level...

Maybe pressure test the cooling system to see where it's getting into the oil.

I would suspect heads.

Anthony, I think you got yourself a "problem" as it were.........


In a marine engine with water in the oil, it's suggested that the block & heads be pressurized with 15-20 psi air and see if it holds. If it doesn't, then listen for the hiss or use soapy water on the outside and look for bubbles.

You do this by isolating the block and heads (cooling system wise) by disconnecting the jacketed exhaust manifolds and risers oil coolers and/or other external cooling system connections


On this engine, the same principal applies as long as the intake manifold (if it's removed) doesn't have cooling system ports in it. just block off all the outside openings and disconnect hoses (&plug the holes) to the EGR and oil coolers.


You're just treating the block and heads as a big air tank with several openings. block them all except for 2 where you connect a gage and a valve/fitting to your air compressor.

pump it up to 20 psi or so and close the valve and listen.

If the block is cracked, you'll hear it. If it's external you'll probably see it. and if it's internal you'll hear it in the oil fill tube etc........

APR to about MAY is about the time the "boat" people are discovering that their inboard or I/O boat has a cracked block (milk-shake oil) because someone didn't winterize correctly (or at all!!)

Screw me once- shame on you, screw me twice.....

Your previous experience with these coolers/seals have convinced me to never put a Dorman product on any of my vehicles unless it's an emergency and even then only if it can be replaced again in less than a half hour.

 

I would check oil cooler.

 

Cascade liquid dishwasher soap does a better job of getting the oil out of coolant system without foaming.

 

^^^^^ What he said.

FWIW, it seems the biggest issue with the Dorman cooler has been the gaskets and not the actual cooler itself.

Josh

 

The purple color tells me only one thing. They changed the color of the dye in they
put in the gasket compound. Not the compound it's self.
So the big question is will it leak ?

I think if I had to use that cooler I would use Ford gaskets all around.

Sean

 

Or re-use the old OEM gaskets....
