Oil comes out the back when I start it on the trailer???

1995 sea doo spi.......Rebuilt carb.....new black fuel lines.....new plugs, compression at 145, runs great on the trailer. Took it to the lake on Thursday but it was a no wake lake so I could only putt around. Tried to start it on Saturday and it acted like it was flooded. So I put gas in the carb and it took a little bit but it finally started but was running rough and I had the throttle at wide open. After a few seconds it started to clear up and ran great. There was a lot of smoke which I expected but I didn't expect to see a puddle of oil on the ground in the back and oil splattered on the wall of my garage??? It was running good on the trailer so I took it out to a lake yesterday, a different lake where I could actually open it up. Ran good for approximately 10 minutes and died, got towed in and it never started again. I fear that if I pour gas into the carb again it will do the same thing as before, thoughts on this??
 
I have 2 older skis and from what I know about them, you did load it up. I know this because I had this happen to me on both skis.( even the oil splatter on the garage wall) As far as why it died again? I can only assume you didn't change the plugs and she loaded up on you again. Pull the plugs, dry out the engine, put in new plugs. Good luck
 
The crank shaft seal could be going bad which allows oil to seep into the engine while being stored.

Pinch the line that runs from the oil tank next time it is stored with a pinch clamp. Remove the clamp before you start it. If little to no smoke then you know the seal is going bad.

Pretty common issue. Pinching it hurts nothing. Just remember to remove it before start up.

I'd hang my lanyard on it just so I wouldn't forget to remove it.

The previous owner eliminated the oil lines and just uses premix gas. If its loading up, it could just be a carb adjustment??

Some engines, and I don't know which, MUST keep the oil tank as that is what lubes the lower end. [MENTION=16022]Dr Honda[/MENTION] can clarify and/or correct me.

Lots have the oil bypass but still have the oil tank and must keep the tank. It just isn't used for the running of the engine.

Maybe, could be a leaky needle and seat, pop off not set right, also Coastiejoe is trying to give you some good advice about the oil tank. Did the PO know what he was doing when he bypassed the tank, if not that may have something to do with the engine shutting down while running good. You need to check and recheck everything and wait for one of the people that can really advise you on your particular ski setup. There are a lot of people here that are more than willing to help, do what they say and you will work through your problem.
 
I would be willing to hook up the oil tank. Looks like two hoses which shouldn't be tough but there are two light blue wires that have been cut, where do they hook up too? I have a feeling that it'd loading up because it's getting too much oil and after running for a few minutes it just floods the plugs. I am using a 32:1 premix with some probably less than desirable oil.

I don't believe I've seen a no wake lake down here in Ga. So is it a lake that they are trying to keeping boaters out of?
 
My knowledge is not good enough to advise too far, I am new to skis myself, not to mechanics. If you do not have a shop manual I suggest you go here and download shop, operators and parts manuals for free, seedoomanuals.net . There will be someone along shortly that can advise you. I do know that these engines are sensitive, lubrication is just the oil that is in the gas, too much oil fouls plugs, too little oil fries engine, the wrong type oil can fry engine. If you study this forum you will find lots of info, I have learned a lot just by reading existing posts, some are the stickies that are at the top. I will say that I would not run anymore until you are sure you have the proper oil and mixture. Pull plugs and check condition, fouled, oil soaked. Does engine turn over easily, is compression still good, what are the numbers, what engine do you have, all of this will help diagnose your problem. Hope you get your problem resolved soon.

The purchasing owner probably looped the oil lines. Or at least I hope that's what they did. Make sure the lines are at least looped and and where the lines meet is higher than the lowest point ofthe engine because the oil is gravity fed to the rotary gears, then work on finding an oil tank. As to your original problem it sounds like a crank seal but it could be other things.
 
The tank is still there...should the pump still be hooked up or not? It was hooked up when I took the carb off for the rebuild so I just kept it hooked up.

This is what I was speculating to him in my post.

I tried to explain it but he didn't seem to receptive.

You NEVER know what the PO did and they are often wrong, mistaken or lying to you.

But,,, all we can do is try to help. They have to want it for it to be worth a darn.

I have seen posts go PAGES before the poster finally looks at certain things. I think that is where we are in this case.
 
Obviously I'm confused on why my ski runs for 10 minutes then wont start. When I do get it started, oil blows out the back. I'm also not making the correlation between the lil tank and my issue. I appreciate the advice, please don't take my ignorance as disrespect.
 
maybe a couple pics would help.

Ok let me break it down because I can see you don't know why a leaking seal would cause your problem. The counterbalance cavity it separated from the crankcase by a seal. The oil is gravity fed from the oil tank into the counterbalance cavity so if the seal is leaking oil will condtantly get into your crankcase, so when you fire it up you have an excessive amount of oil your mixture.
 
Too much fuel can cause flooding, and also spooge, which is oil in the exhaust(oil puddle should be in crankcase but too much fuel pushes this oil out the exhaust. (Running on trailer is not a way to judge this, or most anything, except to confirm the engine runs, and on both cylinders) A leaky crank seal (if rotary valve engine) can leak oil into the crankcase, excess oil will come out exhaust.

Don't run your ski in the garage, it will blow oil on the wall.

Adding gas to an already flooded engine makes it more flooded. Fuel flooding is often a carburetor problem.

I'm guessing your plugs may be fouled.

You have to keep oil in your oil tank in the case it's an rotary valve engine, the rotary valve driven gear must run in an oil bath else it will be ruined.

I didn't take it as disrespect. A few people gave what I felt as sound device and I felt you didn't try their suggestions. Probably because you didn't understand what they were saying.

And that's fine as we have all been there done that and have the T-shirt to prove our learning curves.

My point is, unless you check and or confirm things we simply can't help.

We are potentially 1000 miles away from you. You MUST be our eyes. We can't assume anything and neither should you.

All the info you can provide will help us help you

I mean no disrespect either. Just stating what I have seen countless times as the owner KNOWS or think they know something so they either don't check it or say what they think we want to hear.

Again, sorry I in offended you,,,
 
Yeah my oil tank is dry. The PO apparently didn't know what he was doing.

I have read so many posts today I do not recall if you have done a compression test?

If so, what were your numbers.

Without the tank doing its job I am now worried about your engine regardless of any other issue at this time.
