Very slight oil over fill...problem?
Hi folks -
In doing an oil change on my Yanmar, (3YHM, 30hp is the model - I think - it's an '05 engine), I slightly overfilled the sump.
The oil level is about 1/8 inch or so above the high mark. This is a couple of days after the change, on a cold engine check. The engine was run for a few minutes after the change with no issues.
Not having ever overfilled an engine with oil, by any amount, is this something to be worried about - or should I just promise to be more careful next time?
Thanks -
Bill

Aloha Bill,
I don't think that that amount will be a problem. I wouldn't be too concerned but if it does bother you is it hard to drain just a bit?
Kind regards,
JohnL

Aloha!
I thought about it, (draining a bit), but it would be a bit of pain. It's not like I'm losing sleep over it; I just thought I'd get some opinions to see if I should be losing sleep over it!
Thanks -
Bill

A "little" oil over aint nuthin. Even if you "really" overfilled it, I couldn't see it being an issue. Excess oil will find it's way out of the system into... who knows.
But wherever it goes, a little oil nevr hurt nuthin... Exxon Valdez - Wikipedia, the free encyclopedia
Cheers
Bill

Don't worry about it.
2 quarts over would have it burping out and/or it would be inhaling it into the air intake and burning it.
You can probably be over as much as 1/2 quart without a problem.
I have been there before with a 3HM35F. No biggie.

A mate of mine had his brand new Landcruiser serviced. It was overfilled and on the way home, the excess oil somehow came back into the air intake and the motor ran away. He simply had to pull over to the side of the road and let it rev itself into destruction. He had a two year battle to get reimbursed for the destruction of the motor. an eighth of an inch over should not be a problem

if it worry's you. get another filter and swap them out. The new dry filter will lower the oil volume to below the high mark. running between the marks is acceptable.

Wouldn't changing the filter be a bit messy with a full crankcase? seems to me that pumping some out would be less of a pain (and mess).

changing the filter is a mess with an empty crankcase
oil is held in the filter and in the associated oil passages. Anytime a filter is removed oil dribbles out. A few min with paper towels and 409 fix it every time

As I said earlier, I'm not really worried about it; it is a very slight over fill. I was just wondering if it's a mistake that needs to be corrected.
From the input I've gotten here, (and from other places), it sounds as if I'm alright.
Thanks to all who've replied -

Agreed no action is needed. Just be more careful next time.
Regarding significantly overfilling, the biggest worry is filling the crankcase to the point where the crankshaft whips the oil into an aerated froth, producing inadequate lubrication and increasing bearing wear.
If the rings are in trouble and the walls are scored up, then I'd worry about a runaway engine, too. A thick rag over the air filter will smother in the intake and stop the engine (thin rag, open air intake pipe, Bad, Bad, Bad!). Worry more about inadequate lubrication.

Hey Bill, First let me express my envy over your boat--sweet. And then let me asssure you that the dipstick is likely as not to have been machined/stamped to far looser tolerances than you could imagine. Do not even give it a second thought.
