6.2l Pcv Catch Can

[DaveH71]

Just thought id throw this on here, its a PCV catch can i bought. Just a husky brand mini air line oil seperator. Has a cintered brass filter. Got it at home depot for 12$. As you can see at only 50 miles on it there is already a little bit of oil inside at the very bottom and the whole inside of the plastic container has an oil coating. Probably be a good idea on any engine. If you do decide to go with this filter make sure you plug the bottom drain somehow or else it will create a vacuum leak. I just melted it shut and put a vacuum cap over it to be safe. Works great and is only 12$.

i've always wondered, what happens to the oil if the catch can wasen't there?

[DaveH71]

If the catch can isn't there all that lovely oil coats the inside of your intake manifold and intake ports and everything else in its path till its gets to the combustion chamber. Id recommend this be done on any motor especially the L series motors. They seem to be real oil eaters.

i don't consume barely any oil

[DaveH71]

Probably not a significant amount that you would notice on the dipstick but trust me its getting sucked in there. I just prefer too keep my engine as clean as possible.

[DaveH71]

So i was playing around with my catch can again and i think i came up with a better way to mount it, looks a little cleaner now. Plus i can use my engine cover.

Not bad, you have given me an idea.

[DaveH71]

oh yeah forgot to mention i put a pad of industrial strength Velcro on the back of the filter itself to hold it to the engine cover. The zip ties are mainly to keep the filter level and flush to the cover.

Are there any downsides to doing this mod? Would heat affect the piece over time? How did you connect the hose to the existing PCV hose? Did you require cutting the stock hose? What diameter tubing did you use to splice the oil separator in there?

 

Sorry for all the questions, but I'm interested in doing this. Thanks

[DaveH71]

No down sides that i could think of, except maybe having to unscrew the catch can and clean it every now and then but thats to simple. I just used hose clamps and 3/8 fuel line hose from autozone to run the line. Connected it to the valve cover port with a clamp. Then cut the stock pcv hose back till there was about 3 or 4 inches left were it goes into the intake and clamped the rubber hose onto that. I dont see heat effecting anything. Its a solid piece of aluminum and nothing is in contact with anything that gets hot at all. Hope this helps.

Just a couple of other examples for your consideration:

Here is a pic of what comes out of the catch can on my mates mazdaspeed3, this about 2 months worth, take about a day to settle out into layers, pretty gross

I don't get it.. Whats the purpose?

[BigBlueLB756]

Keeps the inside of the intake manifold cleaner. Oil mist condensate from the PC opening gets deposited on the interior surfaces and is drawn into the combustion chambers, where it supposedly is burned. It can coke up on the heads of the intake valves. Doesn't hurt to catch it before it gets to the manifold. Some choose to; some choose not to; your choice.

I was under the impression that synthetic oils had a higher vaporization point than 'dino' oils and would be somewhat less of a concern in the intake system.
