Prior to that problem, I have been having idle issues, surges. Spark Plug fouling. Finally, the catalytic converter was just fully blocked. I can't even make 10MPH.
I know there was some discussion here before a long time ago regarding Catch Can. I just wanted to share this information. I finally decided to create one on my truck to prevent gunk on plenum, intake, valve, spark plugs, cat conveter. I don't want those excess oil/gas mixture from going out of the PCV and into the plenum. As you can see, the EGR also returns unburned oil/fuel mixture out from the Exhaust system and back to your plenum. If you vehicle has been pumping a lot of oil/fuel mixture out of the PVC and into the intake, those excess oil/fuel mixture clogs plenum, intake, valves, spark plugs (fouls), also affects the fuel injectors, O2 sensors, catalytic converters. EGR is also another part which returns back unburned fuel/oil mixture and dilutes air/fuel mixture and incrase octane requirement for combustion. Over time the EGR pipe and the EGR itself gets clogged up so badly and it might get stuck open and probably cause for vacuum loss.
If the oil/fuel mixture that comes out of the PCV valve is catched in the first place then it would greatly help the engine performance and eliminate oil/fuel fouling of components or eliminate gunk build up from happening in the first place. You may not prevent 100% carbon build up in your engine but at least you would eliminate the no. 1 source of those carbon build up and engine problems.
Remember, if you are still burning oil and having to put oil a quart a month or so, you would still continue putting a quart every month or so. However, instead of those oil going back into your intake, you are catching it instead and dispose them properly like you would when changing oil. Autoparts store accepts used oil now for recycle. Do not attempt to put back into the engine the oil/fuel/water mixture that the catch can store.
1. Air/Water Separator from HUSKY Part# HDA70603AV (3/8 In. NPT (Female) ports).
2. (2) two 3/8 In. NPT Male Hose End (3/8" Barb x 3/8" MIP).
3. (1) one pipe Thread seal tape.
4. (4) four hose clamps (smallest one that fits 3/8" hose).
5. (1) 3-4 feet 3/8" fuel hose.
Air/Water Separator from HUSKY Part# HDA70603AV (3/8 In. NPT (Female) ports).
Remove the inside filter component of the Air/Water Separator.
Coat the 3/8" NPT male hose end with pipe thread seal tape.
Connect both the 3/8" NPT hose end to the sides of the Air/Water Separator.
The location of the Air/Water Separator is important so that it won't get broken or hitting other part of the engine. The farther away you put the Air/Water Separator, the longer 3/8" fuel line you would need.
On my 1999 Dodge Ram 1500 4x4 V8 5.9L, I mounted my Air/Water Separator above and near the PCV valve itself and I use a zip tie to secure my Air/Water Separator on the large bundle of electrical wires which is about 1 inch in diameter (which is strong enough to hold my Air/Water Separator).
Disconnect the 3/8" hose from PCV valve and connect it to the 3/8" NPT male hose (OUT) port of the Air/Water Separator. Put a water hose clamp and tighten it.
Connect a section of the 3/8" fuel line to the PCV valve. Put a water hose clamp and tighten it. Route and measure the other end of the 3/8" fuel so it has some slack when connected to the (IN) port of the Air/Water Separator. Cut the desired length of the 3/8" fuel line and then connect it to the (IN) port of the Air/Water Separator. Put a water hose clamp and tighten it.
Here's my final design and location of my Air/Water Separator. This should help my spark plugs from getting fouled up, prevent my plenum, intake manifold, valve, etc from getting gunked up. It should also prevent my catalytic converter from getting excess unburned oil which can cause the catalytic converter to get plugged up.
