Using Oil advice needed
Help and advise needed
i have a 2007 RXP, open loop cooling. I am loosening a lot of oil and think it must be passing in the oil cooler or head gasket gone letting the oil in to the cooling system then out. Lots of oil around ski when sat in water.
As as anybody seen this before and if so what do you think it could be.

Could be the water pump shaft seal too...

I would check the driveshaft seal/boot. Put your hand down in front of the driveshaft, and check the bottom of the black rubber boot. If that seal is leaking, it will drip oil into the bottom, and the siphon bilge will pull that oily water out the back, leaving an oil slick near the ski like you describe.
Best thing is to clean/dry the engine well, then check closely for leaks after running it. They don't usually leak when not running. First thing I would check is the driveshaft seal, they do leak sometimes, especially after pulling the driveshaft and putting it back in.

I have pulled the Scer hose and found some oil in there. There was also a very small amount in intercooler.
I have attached a few photos.
Do you think it could be the seal in the Scer. I am running a mini rude with about 20 hours on it. I think it has the oem seal fitted in there.
I topped the oil up last time I was out on ski and had to put around 2l oil in yesterday again. Did about 60-90mins on ski and oil light came on. Oil was at bottom of the stick again.
Took the spark plugs out and they look ok, so I am not thinking it is passing up the bores. No oil in catch can just a small amount of water.

I would say your front oil seal in the Scer is bad...Time to replace it with a Viton...

Sounds like snoman is right on the SC seal, But if you are also seeing an oil sheen after sitting in the water, your Oil cooler is leaking as well. My RXP is open loop, and noticed the same thing when sitting after shutdown, and at idle while doing sharp turnsi Could see drops of oil coming from rear water dump, then sheen on the water. Changed it out, and no more leaks.

is there oil in your cooling system? I find it hard to believe the supercharger seal would cause that much oil to be lost in such a short time, anything is possible though.
If your oil is infact making its way into the cooling system, its very possible the PTO cover gasket is bad. I had this happen to me one time.

If your open loop your waterpump shaft is rusted and the seals are shot.
