Oil catch can electricity kwh


What he said. Why are you trying to run it this way, anyway?As far as I understand it there are two points where oil vapor gets introduced back into the intake system. The PCV system where it enters back into the intake and at the Valve cover where it is also introduced back into the intake just at a different point. I’d like to eliminate oil vapors getting introduced into the intake gunking stuff up over time. The motor I swapped into the car has over 100,000 miles on it. Even though the cylinders still had some crosshatch and weren’t scored I can’t say what condition the rings are in without doing a leak test. Granted it may be overkill and I realize that this is more for those that are boosting the cylinder pressure hence more blowby but I would like to install one mainly for piece of mind besides……I got a killer deal on a 3 port mishimoto style catch can!!! 2 input ports and one output port.

Check me on this please. I plan on running a hose from the PCV valve to the catch can. Does the valve need to be operational or do I hollow it out and use the body more for sealing up the port? My guess is to leave it operational as it meters how much pressure is in the crankcase although from what I’ve read negative crankcase pressure is what is desirable. If this is so and it won’t mess up the engines operation I can go to the JY and grab a PCV and hollow it out. If I can find a good deal on AN fittings then I will go that route but if not then I’ll just use some sort of clamp. Maybe a Gates Power Grip heat shrink clamp……

The PCV valve actually allows a metered amount of air to be drawn through the engine, mix with crankcase fumes & water vapor and introduced back into the intake manifold. There, it’s mixed with the fresh incoming air, and burnt off with the next combustion cycle. It’s ment to burn off moisture and oil/gas fumes from the crankase so things don’t get all rusty and sludgy. If you’ve ever worked on a pre-1964 engine that was not taken care of, you’ll know what I mean.

The valve cover breather element is basically open to atmosphere, so you can leave it stock or put a little filter on it. Whatever you do, air should be able to flow through it. DO NOT run it to the oil catch can. If that is done, it will create negative pressure in the crankase and no fumes will be evacuated. There shouldn’t be any air going out the valve cover element unless the PCV valve or hose is blocked.

Also, I verified the airflow on my own car by removing the hose to the breather element and placing my finger over the end of it. There was definate suction, and after about 10 seconds a horrible screaching sound started. Sounded like an alternator or water pump bearing about to sieze. Not sure what was going on (maybe air being sucked past a seal), but I don’t think these engine were made to be run in a vacuum.

The only time the gasses are evacuated is when the engine is not at idle (low vac). At idle, the vc breather is sucking the fresh air in and im is applying vacuum on the PCV (the rattling ball is sucked up to close the valve). PCV is an emissions system, I doubt you’ll have issues running it like you want to. I don’t even have a catch can on my turbo setup, somple a hose that’s pointed to the bottom of the engine bay (with gutted pcv valve) and exposed vc breather.So just to be clear, I have a 3 port catch can. I was under the impression that the VC was also expelling gases but Brent set me straight on that. Since the only area that needs to be ventilated is the PCV then I will need to plug one of the inputs and run the output to where the PCV normally exits into the intake manifold correct? I was basing the 3 hole CC by a picture that Anthony(AntMachining) had posted. He had two hoses in going out to atmosphere. I had looked for that picture but have not been able to find it. I tried to go from memory and thought that one of the inputs was from the VC but obviously that is wrong. My guess is that since he has a turbo he is exhausting gases from there along withe the PCV?

Question. Would it be advisable to stick a piece of stainless steel wool inside the oil collection chamber to condense the oil and gas vapor? The Mishimoto unit only uses a baffle to condense the vapors although it does use a brass fine mesh to filter out anything vapor left but I’d like to try and catch that vapor prior to it hitting the filter.
