Nick, I cruised thru your website and cannot find a catch can listed anywhere.

I understand your point but you have to realize we have rules to follow as a dealer. We can not publicly post prices lower than MAP which is a rule of the manufacturer's. If MAP rules are broken we can be suspended or even terminated from the Brand's contract. No one gets a better price than others. We price everything for you guys very low as many can attest here.

If you notice just about every vendor will send pricing privately and this is exactly why. The ones that arent either are posting MSRP or dont know any better and eventually will get a slap on the wrist from the manufacturer.

I assure you there is nothing shady with us. We have been on here for a while and I have been here and very active for a while now as well. We are not here to make a huge sale on bail. We are here to build a steady customer relationship and help the community here. I personally have loyal repeat customers here and I am sure they can vouch for me.

The mfg's web site is 119.99 and you are 120.00 so how is that less to cause trouble

searching their website is brutal. best to just pm him. Ive given his website a try several times. just ends in frustration. so i just pm him. He has great customer service. but whomever is in charge of that website should reconsider their profession.

Oil Catch Can Benefits On Most Engines
So why does somebody need an Oil Catch Can Tank ? The reason is, that the valve rings do not create a perfect seal. If they did the pistons would not be able to move up and down. Because there is a tiny gap between the cylinders walls and the pistons, a little bit of pressure is able to escape into the valve cover area and crankcase. At the same time burnt oils are also escaping into the valve cover area. This is called “blow-by”. The contents are nasty and will eventually make its way into the PCV line and Breather. The PCV line will recycle these burnt solids back into your intake manifold which will increase the level of carbon solids, and reduce your octane levels. For a boosted setup with turbo and supercharger, the Breather line will recirculate some of these oils into the intake which will go into the intercooler. Of course, the intercooler works best when the interior surfaces are nice and clean. When the breather line returns any fumes with oils into the intake, this will start to coat the inside of the intercooler with oil, and reduce the heat exchange efficiencies.

So, the simplest solution is to insert an oil catch tank can into each line, this gives these heavy oil solids a place to enter and pool. There are many shapes and sizes, and even different configurations which are closed-loop, and open loop.

There are various negative effects of not having a properly designed Catch Can installed and allowing excess oil vapor contaminates the intake system from the stock PCV system – such as:
  • Throttle body and/or MAFS (Mass Air Flow Sensor) malfunction or failure.
  • Air filter, intercooler (if equipped) and intake ducting contamination if oil pools and run back out the intake system after engine shutdown.
  • Reduced octane of the air/fuel mixture, which can cause detonation and the ECM (Engine Control Module) to retard timing, thereby reducing engine power.
  • Excessive carbon build-up on valves, piston crowns, combustion chambers and spark plugs. This also increases the chance of detonation and power loss.
  • Increased emissions & possible contamination of catalytic converters and oxygen sensors.

And I don't mean our illustrious forum members :)

Would be helpful.

Thanks.

I keep seeing claims (like in the above article) that a catch can prevents the MAF sensor from failing, or getting dirty, but the MAF sensor is before the spot where the PCV enters the TB. When they make claims that make no sense, that makes me wary of all the claims.

What does it for me is that a catch can is nothing but a little metal can and a couple of cheap hoses and look at how expensive the critters are.

You can make one yourself for almost nothing if you'd like. I made one for a Cummins 6BTA in my boat out of PVC pipe and a couple of plastic fittings. Made one for my diesel jetta out of a small can and a coat hanger.
Here's the one I made for the boat. Had a piece of oil diaper inside to absorb the yuck. Layed down next to a stringer and was vented to the outside. Just no room available in our engine compartments.

I do believe it depends on vehicle/engine........pcv or maybe no pcv but breather tube from engine to air filter box/tube...........air filter box/tube to MF/TB

I'm pretty sure every vehicle has the MAF sensor upstream of where the PCV vapors enter the throttle body. The engineers were smart enough to realize you're not going to allow PCV vapors to enter upstream of the delicate MAF sensor wire. It's usually right after the air cleaner.

BTW, just found that apparently Rams don't even have a MAF sensor. Just a MAP (manifold air pressure) and maybe an air temp sensor in the air tube. My old Ford had a MAF sensor right after the air cleaner, far upstream from where the PCV entered the TB. The MAF was very sensitive to dirt, but it seems the MAP is in the intake manifold, and usually doesn't need cleaning. Operates much differently than a delicate MAF sensor.

Yes, i knew Ram did not have MAF......air temp sensor in air tube......I did see someone post a diesel with tube from valve cover to breather box.

Can't seem to find........it was either a 3.6,3.7,4.7......he JB welded a piece to valve cover....the hose attached there & went to breather box.....someone posted a photo of how it attached because his was missing.
