PCV Oil Catch Can, see what your engine is burning!

[BlazerLT]

Yea, it works wonders and you will be SHOCKED if you saw the light brown condensation it is getting out of my engine lately in this colder weather.

Half full of this stuff every week.

nothing has been 'caught' in at least over a month ...

doesn't seem to matter wheather it's 'city' or 'highway' miles ...

weather has been 30 - 45 Farenheit lately ...

Nothing wrong with nothing coming into it.

Often when you change your oil you will see an accumulation until the oil level settles to a point where the crank is not slapping the oil enough to cause the oil to froth and a bit and be carried in the air.

Remember 30f is not that cold at all, the cold temps I am talking about are much colder than that.

You having nothing in the catchcan is a good thing.

Im putting two on mine, found the crap in the garage for the install today.
I should see alot , the driver side crankcase vent tube was full of nasty nasties, so hopefully this will cure that problem.

Actually only use one, two will not do a better job all will actually hinder the cleaning efficiency if you hinder the vacuum too much. The vacuum is the key to sucking up all that vapour and getting it out of the system.

Install one and only one and if you want, just install one large one if you are worrying about capacity. You can get larger more industrial air/water separators. People do use them in this application.

All I know is that I do love to see the crap in the vial rther than in the valve covers. The milky water/fuel/oil mixtures would be going back into my intake and if you saw the stuff you wouldn't be happy.

Ive got two PCV ports, and it wont hinder anything, put 30 psi of air thru it, got 30psi on the gauge on the other end, i gutted mine and only left the diaphram on top.



On the TBI motor there are two of these "PCV" hoses, one to the baseplate of the TBI and one to the slip collar around the top( the one that sucks in oil from the top to make your injectors that awful brown)I wasnt worried about capacity just the fact i have two of these lines and the one that dumps oil from the top is the worst of the two for the engine.

You sure there is two?

One is for fresh air going into the block and one is the pcv gas return.

same here. i love this thing. though one week the stuff thats trapt will be thick and dark brown, the next it will be a runny light brown. im usually dumping it out once every 2 weeks. i try to clean the filter but it looks the same anyway.

I have the same results, sometimes just oil, sometimes runny light brown water mixed with fuel and oil.

The colder the temperature, the lighter the trapped slurry.

I have a 2000 with 95,000 mi. I changed my intake gasket set yesterday (OH, what fun!) I don't run the PCV "filter" setup ....yet. There was a layer of NASTY, oily dirty crud all over the inside of the intake. On the floor of the manifold, the stuff was prob.1/16" deep or more. Used 2 cans of carb cleaner on it.
Would it be safe to assume the build up is from the blow by etc from the PCV valve, which most of would be removed by the filter/ seperator?

[BlazerLT]

No, that stuff all over everything was probably coolant mixing with the oil.

Moderators: Please don't lock this thread, I am just checking in with an update.

Ok, just checking in after close to a year with this mod.

Nothing but great things to report.

1.) I have to dump it every 3 months or so.
2.) No restriction at all. Fitler is intact and is flowing perfectly. I just cleaned it and not one thing came out of it. It is stained brown, but not one bit of restriction or plugging has occured during the last year.

System is working great! And I am glad that my engine isn't burning all this oil I am dumping.

Anyone else have anything to report?

[ZL1power69]

it was performing well on my 95. dumped it every 2-3 months when the fluid level came up to the filter. The filter was a solid brown but still did not affect function. I just sold that truck so im looking to rig one up on my new one. LT, do you have any pics/suggestions on how to rig one up on a 96+ engine? i have an idea of where to place the seperator but don't know where to route the hoses for best flow.

[BlazerLT]

Very easy, I believe some of the photos in this thread are from 1996+ engines. You just have to work on the driver's side instead of the passengers.

[ZL1power69]

yea i found the pics. doesn't look to hard, although, id like to have it someplace out of the way instead of above the distributor. another project for another day.
