oil in air intake
 
Yanmar 2gm won't start since installing new starter, I've been working on other engine projects since the new starter like changing oil, fuel filters, changing zincs replacing worn hoses, and bleeding the lines. This past weekend I noticed oil coming out of the air intake. Any advice?

Of all that work, bleeding the fuel lines is probably the most likely, IMHO. Try again?

Do you mean the oil breather is dripping oil? That's not terribly uncommon if it's a very little. If a notable amount, you may have blockage or blow by in the cylinders. If she ran well very recently and before you began this work, I would doubt either. Can I assume you are certain you didn't overfill the oil?

Edit: did you flip a compression release lever intentionally to bleed or by accident?

I'm with Minnewaska--I'd check the oil level--2GM takes 2 quarts I believe.
