OK. I need some assistance. I have a 1999 Express Cruiser, 454's fresh water cooled, in-boards. I started the motors last weekend and I had an oil slick running out of my through hull exhaust. I also found that I had some antifreeze in the bulge. I replaced about 3/4 of a gallon of antifreeze in the heat exchanger today. I pulled the hoses on my oil cooler and found it milky. The dip stick showed clean oil. I ordered and replace the oil cooler and found that I had also had milky oil by the oil filter confirming that I got water in my motor.
Today, I changed my oil twice and it's just as milky as it was when I started. My fear is that perhaps I now have a head gasket issue as well. I pressure tested the heat exchanger, and it dropped about a pound every 4 minutes but I could not find a leak.
Questions:
- Is there any way to test or figure out what is getting in the oil, water or antifreeze?
- The motor is running perfect, and I alway's believed that if it was a blown head gasket that there would be lots of steam and the motor would run sporadically. Is this true?
- I will pull off the raw water hose from the oil cooler tomorrow to ensure there is no oil in the water, but there's no oil slick in the exhaust so I'm assuming I'm ok there.
- What should be my next steps? Compression tests? Run the motor and see if I can find a antifreeze leak?
Any assistance wold be greatly appreciated!!!!
Thanks
Chris
