    Question RTX 255 oil in coolant expansion tank

    I just purchased a Sea-Doo RTX 255 2009 which had 40 hours on it. Ran wonderful and we p have put 14 hours on it. No sign of problems until I loaded on the trailer I noticed milky white substance coming out of the drain holes in the back of the ski. I immediately opened up the engine compartment and noticed the coolant tank was full of a mixture of oil and coolant. Pulled the dipstick and there is no apparent water into the engine. My question would be a head gasket failure or I saw online where it may be a water pump seal were oil may get into the coolant system. I would appreciate anybody's expertise in this area and appreciate your thoughts. Thank you Tony

    I had the same problem. I thought it was the oil cooler and ended up being the water pump seal as you stated.
