blow off, blow-by
anyone ever have thier blow-by sensor on the water pump that regulates engine pressures go bad? I'm running a stage 3 plus rude charger and today at the lake the engine shut down acting like it ran out of fuel, it would restart almost every time only to die again right away, when I got the ski to shore I noticed that the catch can for the engine blow off was full of what looks like oil but I think its fuel. anybody?

It was half full, Iam using the ecu that auto regulates the fuel mixture. my compression is great all the way across, we did put a dry break on the ski last night and I thought that maybe the fuel screen became clogged and was causing my problem it definatley is starving for fuel

yes, but the big thing is the sensor that sits on top of the water pump (held on by 2 bolts) is getting very hot and buzzing, when hooked up to b.u.d.s. sometimes it will throw a coil code... but it has fire on all cylinders. if you rev the ski it will eventually starve out of fuel and die

We welded a 3/4 male fitting in the Rocker cover.....
Our Ski runs over 330hp and 14.5lbs boost
Our Rings are fine, Compression is fine!
Same deal Fuel and Oil in catch can after every Race.......
Even with the above setup......I dont have the answer but it has never caused me an engine failure or problem yet.....Drain it after each ride and keep the oil topped up....
Check the Following:
Seal behind the Supercharger
Oil too High.

this ski is making some great horse power with that rude s/c, what is the tops valve? is it located under the valve cover? my catch can is mounted up near the gas cap so it is much higher
