OK Guys, I need a little help.....Not to bore you with all the details, I have a the following modifications to my RXT:
New Seadoo Engine
Upgraded 255hp Supercharger
42lb Bosch Fuel Injectors
R&D Aquavein Intake Grate
Resinator Romoved (Added Stainless "J" free flow exhaust pipe)
Rear Air Intake
Now to the problem......When I first took the Seadoo out in the water to start breaking it in (15min varying throttle up to 4500rpms and letting sit to cool down and repeating the process 2 more times), it ran fine. After I pulled it out of the water the checked the engine compartment I noticed a little oil leaking from a rubber gromet with 2 wires going into it ( I was told this was where the magneto goes). I informed my engine guy, he looked at it and said the engine was building compression and it was pushing a little oil out of that gromet. He cleaned around the gromet and sealed it with water sealer and said that more than likely the rings and seals hadn't seated good yet which could be the compression issue and the next time out to pull the dipstick out a little to let the engine breathe. I did that and took it out on the water Saturday and did the same riding, this time up to 5500rpms X3 (got a total of 5 1/2hrs on new engine now) and when I docked the Seadoo and checked the engine compartment, it had blowed oil out the dipstick tibe and oil was all over the plastic cover on top of the engine. Now I've read several different postings and see it could possibly be the TOPS valve stuck closed which could be causing the compression but, I'm not sure.
My question is.....Is there a way to test the TOPS valve? Could it be that the rings/seals still aren't seated good (got a total of 5 1/2hrs on new engine now)? If I was to add a oil catch can would that allow the engine to breathe and eliminate the issue?
As always, thanks for the advise!
