Honda 25 oil level

[fla.sailor]

Hey folks,

The oil level on my honda 25 HP (4 stroke) has risen since I last changed the oil (400 miles). When I say risen, I mean almost to the point of almost to the point of coming out of the dip stick tube!!

Any suggestions/ideas? I've been told that it might be a fuel pump issue(?).

Thanks!

could also be simply you laid it down on the wrong side these engines can only be laid down on one side, yes/no?

Dennis,

I have a 15hp Honda and a few years ago I noticed that the oil level had gone up. I called a bunch of places and got a lot of different opinions. Many offers to "drop it off".........you know what that means?

I finally found an ex-outboard repair man (Honda) who asked a few questions first.

As it turns out I was very careful to close the tank vent each time we stopped the boat to cast at "that" spot. Don't want gas fumes collecting in the bottom of the Jon boat.......how paranoid is that when with the kids.

Well, what happens in the Honda is that the sun shining on the tank makes the air warm and............you don't need the physics explanation.........the gas gets forced into the engine.

I don't remember the pathway.....well maybe.......if an intake valve is partly open the gas is forced (over time) past the rings. Don't ask me how it gets past he carb - but it does.

Maybe this is your problem. The heating and cooling of your tank, even in a locker.

Cure for sure - disconnect the fuel line when not in use.

Thanks for an idea! I'll disconnect next weekend and see what happens - this has to be cheaper than the ole, "drop it off"

CHeeRS!

Is your oil clear and not emulsified (sort of a caramel color)? If its emulsified, then its water getting in and pushing the oil up. If that is the case then stop using it and get it fixed ASAP.

Nice clear oil (Ames), no water - been there done that with an ole truck!

thanks for the suggestion!
