4-stroke engines of any sort in my experience will leak oil of tipped on the wrong side. The crank case venting goes to the intake manifold so that crankcase fumes will be burned in the engine and so pollute the air less. The crankcase must be vented to allow for piston displacement, especially in a one-cylinder engine, but in all of them because of combustion gasses that blow past the piston rings, among other reasons. So follow the instructions! --Gary Hyde Pullman, WA gmhyde1@mac.com M17 #637 'Hydeaway 2' "...There's nothing quite like messing about in boats..." On Aug 14, 2006, at 6:25 PM, William B.

Bob,
I'm no engineer, but there is certainly a good reason for not sealing the crankcase on a four-stroke outboard. Maybe heat-induced expansion. Maybe something else. But it couldn't have been an oversight.
After viewing the amazing Honda video, I would never question their engineering. (see the email and link below - even if you don't have broadband, it's worth the download time.)

Dear SWSers, I just had to forward to you this email from my son. Ken
From: bryan murphy To: kgmurphy@comcast.net Subject: Honda Commercial
Dad, This is the ad I was telling you about:
There are no computer graphics or digital tricks in the film. Everything you see really happened in real time exactly as you see it. The film took 606 takes. On the first 605 takes, something, usually very minor, didn't work.
They would then have to set the whole thing up again. The crew spent weeks shooting night and day. By the time it was over, they were ready to change professions. The film cost six million dollars and took three months to complete including full engineering of the sequence.
In addition, it's two minutes long, so every time Honda airs the film on British television, they're shelling out big bucks.
However, it is fast becoming the most downloaded advertisement in Internet history.
Honda executives figure the ad will soon pay for itself simply in "free viewings." (Honda isn't paying a dime to have you watch this commercial!). When the ad was pitched to senior executives, they signed off on it immediately without any hesitation - including the costs.
There are six and only six hand-made Accords in the world. To the horror of Honda engineers, the filmmakers disassembled two of them to make the film.
Everything you see in the film (aside from the walls, floor, ramp, and complete Honda Accord) are parts from those two cars. The voiceover is Garrison Keillor. When the ad was shown to Honda executives, they liked it and commented on how amazing computer graphics have gotten. They fell off their chairs when they found out it was for real.
Oh, and about those funky windshield wipers. On the new Accords, the windshield wipers have water sensors and are designed to start doing their thing automatically as soon as they become wet.

Outboard motors that leak oil into the cylinder in certain positions and consequently won't start are in my view fatally flawed because they will inevitably end up on the incorrect side occasionally. Sounds like Honda didn't think things through when making the transition from 2 to 4 cycle. I wonder what the company has to say for itself. Have they fixed the flaw? Someone who owns one should write the company on behalf of the group. As it is, they are getting a lot of really bad publicity among Montgomery fans.
Don't you just hate things that don't work?
