PCV VALVE... Really?

Mo, Also I'm thinking the system should be designed with continuous uphill plumbing so that oil drains back into the engine during shut down periods.

You need a catch can in the system. Hose goes downhill to can and then back uphill again. Empty the can every now and then.

Exactly

Exactly Joe.

I dunno if I am ready to ditch my PCV for a Li'l Stanker, but I may get one of those to ventilate my holding tank!!!!

I have a spare blower motor sitting in my garage. Agreed Neil... ...What about a smaller blower motor used in conjunction with a small hose such as heater hose. It couldn't help but solve that problem. Smaller hose would draw less power, and could be rigged to come on with ignition switch.

The only problem would be were to put the exhaust. If I had to do it I think I'd make another through hull in the transom for it. Currently my blower is what I consider noisy and exhausts in the cockpit... so I don't think exhausting blow-into the cockpit is a plan. Smaller motor should be quiet as well and it wouldn't need much to move air / blow-by through the hose.

Hi Mo,

I was wondering if you run your blower while the engine is running? I have the blower wired to the ACC position of a new ignition switch - like a car radio. That means it is ON all the time when the engine is running. I thought that was a safety requirement.

I have two engine compartment ducts running to topside cowlings: one to draw air IN and another to draw air OUT. The IN side points forward to the cockpit. The OUT cowling points over the stern, so there is no engine smell.

Also, on draining the gunk/oil out of the hose - wow! You must have a serious problem. Most of this is vapor, no? I haven't noticed any residue yet. But I will keep an eye on it now that you thought of this. Thanks. <-- (Actually rats! now I have one more thing to worry about!)
