How the heck..........

7 posts in this topic

I changed the oil in my Yammi 115 4-stroke last night. When I finished draining the oil, I noticed that there was almost 6.5 quarts in the bucket. The motor capacity is listed at 4.8 quarts......

Ok so they put too much in, right.......

Wrong...The oil smelled badly of gasoline.

How the hell did 2 quarts of gasoline get into the crankcase?????????

Motor runs fine.....so I can rule out bad ring or blown cylinder.

Any thoughts from the motorheads in the audience?????

Motor is a 2001 and is under warranty. I am dropping it off tomorrow to be looked at, but wanted to see if anyone else has had this happen and what was the prognosis?

A friend of mine has the same motor, he also had some gas odor in the oil, you could smell it on the dip stick, a mech. told him he may not be running high enough rpms often enough, or in other words use wot more often. we also noticed that if the motor is not perfectly level, it would show on the dip stick that there was either more oil in it or less, mabey it had too much put in??

Imagine that your Chevrolet Mech. told you on your 2001 Silverado that if you didn't run it at WOT frequently that straight gasoline would creep into the crankcase.

This is a horrible reason and explanation.
Obviously there is a problem with your motor.

Let us know what the dealer finds,

Motor is sitting at Pierz in Shakopee. I changed the oil myself and ran it on Friday....Didn't notice any odor after about an hour of operation.

The guy at Pierz just said keep an eye on it and bring it in if it happens again. Gee that makes me feel better!!

I'll post it if they find anything.

I have a 1987 dodge pickup that does the same thing. I change the oil in it,and about a week later there is gas in the oil.If I parked on a hill the gas would just pour in,kinda like a siphon hose. I finally found out that it was the carb causing this problem.
I assume you have a FI engine?? If so the choke could be sticking or not adjusted properly. That would cause more fuel than is being burned to enter your engine. Causing it to leak down into the engine.
It might be a good idea to unhook the fuel line near the engine,while trailering. You should not have to but it could save your engine.
Just my 2 cents worth

    • Well yeah but can you name a vehicle built for off road including any domestic pickup truck that doesn't have issues with rust. Fenders, rockers, frames etc. If you play in the mud and salt you need to maintain them. UTVs are no different. Ask yourself why Polaris would put the air filter canister intake in the rear wheel well so it is sucking in the air from the dustiest area they could possibly draw it from resulting in a 4k bill when the motor grenades.    Jeeps are fun, used ones can be had at a reasonable price but by their nature you need to be careful when you purchase because if the previous owner drove them the way they were marketed then they may have some issues.   But the aftermarket has an amazing amount of mods,upgrades and accessories to make your Jeep into anything you want and because the generally go 10 years between major design changes there are a large number of parts available if you need them.     
    • Anyfish it's still points and way better than a zero for points! Congrats on the fine eating bird.
    • Pick up a Jake morning.  Not going help the team score, if at all.  But it sure will taste good.
    • It's been very quiet in the woods the past few days.  Some gobbling this morning.
    • Nice! Way to go! Hope I'm able to get out and enjoy hunting when I'm that age.
    • Well, one of the advantages to owning a Jeep is there are always plenty of Jeep owners out there looking for parts, so if you get ahold of one with a bad frame, you could always part it out and sell the parts to another Jeep owner who believes they have a good frame....      
    • I am saying if you go mudding or off-roading you will plug any of the drain holes they could put in there anyway. Not much different from the weep holes they put in the rear fenderwells and rockers of trucks.  I suppose it may have benefit to those who stay on pavement.
    • They put holes in the sides of the frame, so salt and mud could get in, but no holes in the bottom so they could drain, so not sure if that was planned, or just p*ss poor engineering.  They probably didn't really care as long as they outlasted the warranty period.        
    • Drain holes just end up getting plugged with mud and debris anyway.
