Since I dont have an EGR valve any more and I would like to keep my IM as clean as possible, I was thinking of installing a catch can on my new motor PCV valve.
Any pictures or places I can get a can ?? I was thinking of just mounting it by the TB so I dont have to run lines all over the place for it. Any good mounting locations you guys think of, please advise.

You guys think its worth it to get one ??

Or another option is just putting a breather on the rear valve cover. NO lines NO cans

 

I had breather on my front valve cover & it oil soaked quickly, sprayed all over the engine bay and made the inside of the car smell when stopped at a light or something. Not usre if the rear would cause the same issues. I've seen others run a breather but don't know if they had my problems.
You can run a air/water seperator inline, get it at a home depot type store. Cheaper and easier than a catch can.

 

Yea thats what Im going to do. I read up on the units and it seems the ones from Sears are decent and fill up fast. The general concensus is that ones from ebay are junk and dont really fill up at all nor work for some reason.

Im boosted so I have the front valve cover venting to air (small filter) with ill effects at all. The filter still looks pretty decent. Ill get one for the PCV--->Intake Manifold

Im kinda afriad of putting it on there, when running boost because the can is going to see boost. I guess it will just past right through it. I would hate for it to back up back towards the PCV.

matty i think you have to run a breather if you are boosted, something about the pcv not supposed to get boost, i.e. anything more than 1atm (ambient air, no pressure)

the pcv gets vacuum from the IM and uses filtered (ambient) air as source from the airbox, or intake (FI: chargepipe) pipe to clean out the blow-off gasses that accumulate in the front, and rear valvecovers (both sit on top of the cylinder heads, valves etc.)

on a N/A application the source has no pressure 1atm, ambient air
on a FI application the source will get whatever boost it is set to. resulting in pressurized air coming into the front and rear valve covers, through the pcv valve into the IM. if you use a breather, you will be using 1atm, ambient air as the source, and still getting boost through the charge piping, just make sure to block off the hole for the PCV hose on the charge pipe or a boost leak will happen.

btw check the hose running from the front to the rear valve cover along the top of the timing chain cover, that hose cracks many times from heat/old age. that can result in vacuum leak

you could buy a catch can/oil cleaner for an air compessor at autozone, and use that as the catch can.


hope this helps

 

Ive always seen it before the turbo on a boosted car. Normaly with oil going into the intake you dont want to put that in front of your turbo but with the oil free air coming out of the catch can its fine.

This is what I use:

Positive crankcase ventilation (PCV) system
The PCV system in modern day engines is designed to remove blow-by gases (un-burnt fuel-air mixture that escapes past the piston rings on the compression stroke). These crankcase gases can foul the engine oil or increase the crankcase stress. Additionally it raises the acidity levels in the oil, which breaks down the oils ability to lubricate properly. Filtered air supplied to the crankcase from the intake hose through the valve cover mixes with the blow-by gases and funneled out of the valve cover vacuum in the intake manifold through the PCV valve. The PCV is a tapered plunger and two springs, and limits airflow based on intake manifold vacuum. Most NA cars are not set up with sufficient PCV systems to exhaust these pressurized conditions, the RIPP PCV eliminates the following conditions.
• Blow by
• Crank Case stress
• Sludge build up
• Oil acidity levels


Under idle, deceleration and cruise conditions the blow-by gases are minimal, the engines vacuum will do a sufficient job in removing the pressure built in the crankcase. However, under boosted conditions and heavy acceleration, the PCV system is under a much heavyier load because blow-by gases are at their highest, a completely normal condition. The intake manifold becomes pressurized and the plungers seat on the factory PCV is forced closed preventing air from entering or exiting the crankcase, ultimately building excess crankcase pressure. Additionally, when the manifold is pressurized the excess blow-by gases now under pressure flow out of any part of the engine it can find such as the valve cover seal or gaskets, oil dip stick tubes, valve cover relief vent and various other “escape routes” the pressure manages to find.

RIPP Modifications developed a low cost and simple solution to this problem, a one-way valve that modify the operation of the PCV system and prevent air from entering the crankcase through the factory PCV valve or the intake hose. Used in conjunction with the Oil Catch Can system we provide you will eliminate the conditions described above. The larger valve assembly installs in the hose that connects the rear rocker cover to the intake hose. Our valves allow air to flow through them in only one direction, the crank will flow only away from the valve covers, maintaining a partial vacuum in the crankcase at all times. The new system will increases engine power and response because power is not wasted compressing air in the crankcase on the downward piston stroke.


This method of releasing crank case pressure is time proven and practiced across the board by all professional tuners and engine builders, no matter what engine you choose to run. However, the RIPP valve is derived specifically for the engine supported in its program, a perfect match for your application. The valve comes with instruction on how to best utilize it in your application, high compression, NOS or Forced Inductions engine will all benefit from it.

So If I do decide to get that, how will it go ??

PCV====RIPP-VALVE====CatchCAN=====Manifold

or

PCV=====CatchCAN===RIPP-VALVE=====Manifold

Matty,
This is the setup.

For some reason many people on this forum don't realize the importance of catch cans.

By the way, I haven't had trouble with my V2 for ages, that's why I haven't bought your new mounting plate. If I need it in the future do you plan on making more? Tying up $700.00 for future use isn't what I want to do now.

Do I spend $70 on that valve or just run the catch can ??

If interest is there for another run, then it will be made. As of now, I have two available but if they sell out and I get more deposits, then more will be produced

"Do I spend $70 on that valve or just run the catch can" ??

Yes, you need both so the can collects the blowby oil.

By the way, I checked the tubing going fom the catch can back to the intake plenum and I found no oil in the tube or manifold.

 

Matty,

I checked with Ripp mods and they sent me this info:

Stock PCV Valve to bottom bottom-side catch can…. Top-side catch can to RIPP PCV VALVE, PCV valve to intake…. The steal wool is OK to use and done by some and not others…

I had my system connected wrong but no harm done.

 

I have never heard of this device...interesting description on their product page...I just hope it's not like the tornado thing....very convincing arguements and description, but no real benefit or effect for $70...!
