Oil catch can.

[Robert Horne]

I seen an item that may be useful to catch the blowby smoke coming from our engines. Found these on ebay, "an oil catch can kit", for about $20. When I turn off my engine in my 38, I see a little smoke coming out of the breather on the oil filler/breather tube.

What are you going to do with it after you catch it?? A PCV system would address most engines in fairly good condition.

[Robert Horne]

I think the catch can would condense the smoke into a liquid, instead of the smoke going into the atmosphere, or back into the engine. One could drain the oil after so much time.

Also available is a dual tank for oil catching and coolant recovery, for only $650.

A PCV system would take care of bypass smoke when the engine is running, but after I turn my engine off, smoke comes out of the oil breather inlet for a couple of minutes. This smoke ends up on the underside of my hood. I am trying to address some type of catch can to catch/eliminate the smoke.

Check out the oil breather on this old Dodge.

That looks like a waterproof millitary setup. Try VPW.

I think I'll let Mother Nature catch mine, after all this is where it came from anyhow. What kind of Enviromental Footprint are we trying to reduce here.

Most of us only drive these cars 1,000 -2,000 miles a year anyhow.

I personally would never connect anything to my Flathead that didn't come with it "Stock". This is only my personal opinion and not meant to rile the sensitive types here. If your Motor has heavy Blow by maybe you should try opening it up and repairing it. I have had several old Flat Head Chryslers and they all smoked a little when shut off, its a fact of Chryslerdom. I guess running 6 foot Flat Screen TV's all over the house with no one in the room while burning some shitty flourecent bulbs is more enviromentally correct.

Geez, I dont know what to say except I agree.

Now back in the 60's I had an old 57 Plymouth (Wish I had it today ) and it had so much blow by and I did not have any extra cash. So with a little ingenuity I just ran a hose back to the rear end of the car and let it out there!!! Nice fix!!!!!!!!!!! I think all us old guys here have done something kind of Mickey Mouse at one time or another with cars we have had in the pass and hay if it worked it was ok!!!!!

Wouldn't a closed PCV system keep your hood clean. Just get a sealed Oil fill cap and plumb it to your air cleaner. The vapors should condense in your air filter.

VPW has options as well.

The catch can you showed doesn't seem like it would work after the engine was shut off and there was no vacuum.

Take care

As a interesting, at least to me, side note the Second Chance Garage article failed to mention that positive crankcase ventilation (PCV) systems were originally developed not to fight smog but to increase engine life. Here are a couple of patents, the first from the 1920s where the inventor uses the exhaust system to create ventilation flow through the crankcase, to compensate for too much flow under some conditions he has a valve actuated by a linkage from the carburetor.

A weird one was filed in 1930 that uses a fan built into the camshaft gear to move air through the crankcase:

In this next patent, filed in 1938, the inventor seems to have specified the modern system with ventilation flow being achieved using manifold vacuum and using a vacuum sensitive valve to control for engine load and speed.

Here is a photo of a "stock" Dodge breather, that is sold at Vintage Power Wagons, which may catch or condense some of the blowby smoke. Simply all I am trying to do is keep a little blowby smoke from under my hood, and the engine bay. My 36, 48, and 56 do not have heavy blowby, but do have a little blowby.

I do not have flat screen TV of any size, but I do have flourescent bulbs that I do not use very much because I have sunlight piped into my shop....

After enjoying a little refreshment, I discovered one solution to my oil smoke

catch can idea, was to install a bottle to catch the smoke, and after the bottle

got empty, I said o heck, just put a cork in it..
