17 wake pro 230 eating oil

[Zigzag]

Need some help here, have a 17 wake pro 230 that is losing oil. No oil in hull and not smoking but lost 3q in 6hrs operation time. Thanks in advance

Does the 2017 230 engine still have a TOPS valve? I've see these valves malfunction and cause excessive crankcase pressure and consequently high oil consumption.

Don't think so but not 100

Did some reading; Yes there is a "TOPS" valve, but now it's called the "Blow-by" valve. It's on the back of the cylinder head. The same test on the older engine would work ... pull the dipstick, and install a pressure gauge; run the engine (not more than 2 min out of the water) and see what your crankcase pressure is. It should be below 4 PSI; when I checked two older skis this week, the pressure was zero PSI.

It's probably best to do this test on the boat ramp.

The engine only has a changeable capacity of around 3 to 3.5 L. If you are loosing that much oil, it should be very visible to where it is going.

It is either

1.. leaking to the bilge. (This amount of oil should be easily visible in the bilge.)
2.. Burning it internally. (Bad rings or valve seals. Either way you would often see blue smoke, which may be hard to see in the water. Try running it on land on the hose)
3.. Burning it through the intake either from the Supercharger seal or the TOPS valve. (Both of these would heavily coat the intake plumbing. The TOPS would coat just below the actual intake filter)
4.. Loosing it to the coolant system. (This would be visible in the coolant tank)

Like mentioned above, the TOPS is a likely candidate.

Looks like oil under tops valve, going to get in there today. Thanks for the help, will update
