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

[BlazerLT]

Since I have been on my vacation, I have installed a PCv catch can on my Blazer. You won't believe the amount of oil this thing is catching. Only 300 miles and it is half full.

What is half full you might say? Well, this...

You will absolutely drop your jaw when you seen how much oil your engine is burning normally. Want to get your engine cleaner, stop the oil from gumming up your intake and your valves!

[JC327]

Ahh, I want one of those. Excellent.

[BlazerLT]

You should see the amount of gas laden oil I am collecting, it is ridiculous.

Imagine, that amount of oil constantly being burned in your engine.

[BlazerLT]

Just as an update do you guys want to see a small video of this in action?

Do you want to see how much oil is in there after 500 miles?

Just as a teaser, it is much more than in this example photo.

[BlazerLT]

Ok, here is the video you guys requested.

Let me know what you think guys. These are my photos this time.

cant see from the photos ... u got any kind of brace or mount? however, I can see the cable ties ...

seems like alot of hose ...

do u think a mount is necessary?

Nah, not necessary at all. There is a lot of hose seeing I didn't want any sharp bends to crimp the lines and restrict the flow.

This whole system installed in 5 minutes total.

Here is what you will need:

-Air Compressor Air/Water Separator
-Two 1/4" thread to 3/8" tube connectors.
-Four 1/2" hose clamps
-5-6 Cable Ties
-5-10 minutes worth of time.
-Teflon thread sealing tape for the fitting being screwed into the separator.
-depending on setup, 4-7 feet of 3/8" fuel line

You can get everything at Home Depot other than the 3/8 fuel line which you can get at you local auto supply store.

Works mint, and also, the oil that is caught DOES NOT get added back into the engine. You might think it is oil, but it is also a good portion fuel and contaminents.

After installing you will notice that you engine over time will start to run smoother and smoother as the carbon depostits are slowly burned out of the combustion chamber seeing there is nothing more being added to keep the deposits forming. Also, this will extend plug life considerably.

Hope you guy enjoy this, I love it, better in that plastic vial than in my intake fouling my plugs.

couple questions for ya LT;
-does this completely eliminate the pcv valve?
-if so, how is this system conected to where the valve would have been (can't see it in the pics)
-whatever is collected in the system, is it just discarded?
-because this system is removing oil from the engine, do you need to keep adding oil every so often?
-where does this thing actually hang in relation to the engine (toward the radiator, next to the manifolds)? maybe a pic from the pass side would help.
-also, is it ok to leave the filter in the separator or does it need to be removed (one link u posted has the filter out but in ur video u left it in)?

[muzzy1maniac]

I wouldn't think you'd replace the PCV it's there as a vent. As for the oil - it would get burned up in the combustion chamber w/o this catch so it wouldn't change your oil consuption. If you regularly need to add oil you still will - if not then you still won't. I gotta get me one of these.

New project!!! DING DING!!!

[ZL1power69]

ok now its making sense. now my only question is after the separator, where does the hose go? does it just connect to the PCV valve?

No, don't remove your PCV valve. One critical function of the PCV valve is to prevent backfiring flame from getting back into the crankcase. It only allows gas flow in one direction - into the air plenum. That's why it's a one-way valve instead of just a tube.

Also, you need to retain the PCV connection to keep removing blow-by gases from the crankcase, not to mention keeping the trap itself working. The PCV valve eliminates alot of fuel dilution and acid contamination from the oil in the crankcase by sucking out contaminating gases.

Yes, just discard the gunk in the trap after it gets half full or so.

I would discard the filter. At worst, it lets a little of the air-borne gunk pass through. You will still catch alot. I am worried the filter will get more and more plugged with gunk over time and restrict the ventilation flow of the vapor out of the crankcase. I think, the more the better. If you decrease the crankcase ventilation, you will increase the oil contamination.

My 2 cents

[BlazerBoyLT98]

Seems really neat. I will have to try this in expensive mod. Cool post and great pics!

No, you connect the hose to the PCV valve in the valve cover, the PCV valve remains.

See above ^^^^^

Yes, some people might think it is only oil, but it is actually oil + water + fuel + other random gases.

Discard it, this is the stuff you don't want going back into your oil. Just dump it into a safe and designated dumping container AKA old oil bottle.

No, this is the oil that your engine will normally consume normally, the only thing is you are removing it instead of burning it. The results will be the same if not less burning seeing you will be keeping the oil cleaning and stopping the excess fuel from thinning you oil out. It is this oil that gums up you intake and valve.

Cliff's Notes: Nothing will change, if anything will change, oil consumption will be lower.

Ok, you have to mount it where it is accessable and where it is safe from being damaged. You don't need to be fancy, as you see, I used cabel ties and it doesn't move a fraction of an inch.

Here is the requested photo you asked for, other year engines like 1996+ will probably benefit from a driver's side mount seeing the PCV valve is in the driver's side valve cover whereas my 1995 CPI engine has it in the passenger side cover.

Again, remember mount it on the side which your PCV valve is mounted.

Yes, leave the filter in, I am sorry I confused you that way. Remember, not all the photos were mine (The photos in the post with the video is mine) . Leave the filter in and it will slow the flow down so more oil will and can be extracted. When I reinstalled the filter, the trapped oil amount went up a lot.

Hope this info helps you.

[BlazerLT]

Oh and remember guys, this mod costs less than 25 bucks.

[BlazerLT]

Just for your information, guys, here is how it goes:

1.) The separator has a flow direction, it has an arrow denoting that direction.

2.) Hose connects to the pcv valve and travels to the inlet side of the separator.

3.) Then the hose connected to the outlet side is connected to the connectio on the intake.

4.) You are done.

See, it is so easy. Just use fuel line and not flimy tubing seeing the gas is hot and the tube will actually collapse from the vacuum and heat.

Also, do NOT try to get cheap with the hose and have the hose turned at sharp angles seeing you will be crimping the hose and restricting flow.

VERY IMPORTANT, KNOW THE SIDE WHERE YOU PCV VALVE IS AND NOT THE SIDE FOR YOUR FRESH AIR INTAKE.
