And let's keep it that way!

 

Just to give everyone a quick update. I removed the filter from the separator and have noted an increase in oil being caught. I gathered more oil in one week than I did in more than a month that the filter was in the separator. As someone mentioned in the thread, the filter was holding the oil in it and allowing it to vaporize and get back into PCV system. Thanks for the tip!

 

Bad idea... the crankcase builds up pressure while the engine is running. In the old days the fumes were vented via the breather cap on the valve covers. With that whole "emmission" thing they started to vent the fumes and oil back into the engine through the PVC valve to be more environmently freindly. If you plug up the PVC valve the pressure from the engine will start to blow out your engine seals. I still can't belive the amount of oil I've been collecting with the addition of this mod. The pinging seems to have gone away for the most part now.

And to whoever is keeping the "Greenpeace most wanted list" the correct spelling is Kirk.

 

^^^ I know its a bad idea, I was just making a joke. But you can remove it beacuse some have done it and I already stated how to do it in this thread.

 

[QUOTE]OK, so, how bout we gut the pcv valve, and vent it to air via a long hose that runs to the bottom of the engine compart, then plug up the hole where it went to intake. From what i've heard this won't even trip a code....secondly, you can just replace the original hose in 5 min for inspection..... I will try it this coming weekend and let you guys know how it goes. Seems like this could be a $0 answer to the blowby prollem.

I'm working on a plan for an external evac unit for the crankcase, one that doesn't use engine vacuum, so therefore could create even more of a vacuum in the crankcase, with NO risk of oil heading back into the combustion chamber. It also has a canister that you empty. Plus, on all out race cars, this can be good for 5-10 horses..... (big v8's) maybe it could help? I'll keep ya'll posted. My dad has built one of these before and offered to show me when i go visit on thanksgiving =) He swears its ultra cheep too. We'll see.

[QUOTE=Jasovanni]Keep us posted, I'm curious.

 

update:

now I know why the little reservoirs say "don't use synthetic oil"....it appears that the synthetic that I use is actually slowly melting/dissolving the plastic reservoir. Nothing big, but when I emptied it the oil was kind of "milky" looking and the plastic was eaten away a little. (and the oil in my pan is brand new, and "clean" so it's not a coolant leak or anything).

might have to switch to a metal reservoir if I'm gonna continue with synthetic oil....

 

hmmm, maxima engines don't have any plastic parts on the INSIDE do they.......

Yeah they do. Your connecting rods are lined with polyvinyl chloride.

 

im doing this to my car tomorow. when i took off my intake manifold it was not too oily, but there was residue non the less. i wonder where im going to mount it though. need to find a spot first i guess.

 

anyone done this mod to drain directly back to the oil pan? That's what i'm working on now.

 

Hm, that's an interesting idea... Can't wait to see how you did it...

 

are their any objections to gutting the pcv valve and venting to air?

ATTENTION

I'm withdrawing my support for this ebay catch can. I installed mine this past summer, took it off today to see how much oil was collected and found it bone dry. There was a thin layer of oil on the inside walls, but none collected. The tubes got darker and darker so I assume it was still getting through. If you do this mod, stick to the oil/water separator or some catch can with a baffle. This one just has two holes in the top. The input is sucked right back out of the output.

 

Genious and original... props! :-D

 

My version of this mod:



It's been a week since the install and there is about a 1/2 inch of oil in the container. I am using Mobil 1 and I'm worried about the warning label regarding synthetic oil. I will try to empty the bowl often to keep the syn-oil from damaging the bowl.

 

I also have the same catch can and I always wonder why I couldn't see the oil in the indicator tube.

 

Update, I actually check my ebay catch can today and there was quite a bit of oil in my it. Although I still couldn't see the oil in the oil level indicator. To be safe, I bought a home depot catch can and put it in series with the ebay one.

 

I bought the bigger of the 2 filter/resivors, has any one mounted one of these yet, im having a hard time figuring out how and where to mount it. Also should i leave the filters in it or just take them out?

 

I took it out and I get more oil collected...

 

wow a lot of posts.. but if i'm not mistaken, BLOWBY occurs when air/fuel gets into your crankcase, causing your motor oil to turn into SLUDGE, eating away your block. ??

 

different kind of blowby

 

I did this on my 98 4runner and it worked like a charm. To bad the car was totaled a month later

 

Like night and day.

 

You're kidding, right? Oil separaters flow in one direction. If you use one in the opposite direction, the oil will flow through the filter first, then will drop into the bowl if it does at all. It may just pile up in the hose and return to the PCV when you sut down your engine.

However, seeing as you took your filter out, it appears as though you just made a glass window to view oil passing through on it's way to the intake manifold

To the person who took out their filter and said that they are catching more oil, you're probably letting more get by also.

Enough of meflaming on you guys. Here is a pic of my setup. I routed a hose from the bottom of the catch jar to the bottom of the car to assist in draining.

Hey, Edward Lee, what are you using to mount it in that position?

 

Absolutely Nothing. The Exit hose is suppoted by the metal tube and the other end is sort of supported by the hose. It feels pretty secure and I don't plan on it giving me any problems. The really cool part of my setup is the drain hose that allows me to drain the oil from the bottom, right by the tranny pan.

 

i wanted to bring this thread back up...

can anybody confirm if the filter is better or worse? in terms of catching more oil....i currently have no filter attached to it, and in only 1 day of driving...i'm getting more oil than i thought.....and my return hose is still very clean looking...

 

well, if you're collecting lots of oil, you're prolly fine. I was getting only a few drops of oil in the first week with no filter, then caught more with it on, but I have the smaller of the two filters....

Least you guys dont have a turbo. My turboed altima would fill up every oil change with about 3/4 of a quart. Have you ever seen oil thats been stuck in a catch can for a few months. Maybe my car was a exception but that was the nastest oil ive ever seen. It looked all chunky and you can actually see where the oil and water separated. The oil in your home depot catch can looks like oil

 

Nice idea.
Hmmm.... why bother with the PCV anyway, why not plug the inlet manifold port and just put a line from the PCV to the exhaust pipe instead... haha

 

This thread and the write-up both are really useful.
