This one really has me puzzled, Here's the scoop.

2003 Aquatrax Turbo, I just bought the thing recently,(my first ski). It was a basket case, hasn't run in probably 5 years. Well, we fixed the corroded wire harness, frozen Turbo, and fabricated an aftermarket waste gate actuator to replace the original one that was a blob of rust. New oil, New plugs, cleaned her up and she ran.

We ran it on our test stand for a couple of days, about an hour total. Got it running real nice, idles fine. Well, when we got done cleaning her to take her out on the water, I decided to run it one more time just to make sure. That is when all of the sudden at about 4000 rpm, oil shoots out from the O-ring seal on the oil filter. WTF ?? :dunno:

I took of the filter, reset the seal, and replaced the filter, except this time I tightened it on a little more than normal. When the engine was revved, you could see the filter move. Well, it blew out again.

I put a different oil filter on it, (Wicks car filter), to see if maybe I just had a bad filter. Started her up and she blew the seal out of the bottom of this filter too.

I need somebody who's a lot smarter than I am to tell me what's going on here. I'm not familier with this type of engine or how the oil pressure is regulated.

I would guess it either has to do with a pressure relief valve for the oil pump, (if it has one), or maybe something is clogging an oil passage.

Any help would be greatly appreciated.

Thanks

My guess would be an oil pressure relief valve like you said. Don't know if this applies to Honda, but many skis have this type of valve (and you are right it is usually in the oil pump) that has a spring type system that controls the oil pressure. If this part got corroded like other parts of the engine, it could be causing too much pressure.

You need a service manual to see if you have a valve like this or not. Bad news it will probably be a beeatch to get to.
