Catch Can Catchings

[Sig Oris]

I know there's difference of opinions on Catch Cans and this post is not intended to sway your opinion.

Just sharing as an FYI as I was a skeptic of their effectiveness.

Since mid December we've had temps from the low 20's, teens, single digits and todays heat wave of 30 degrees.

I'm in Western Maine about a 1/2 drive from Mt Washington in NH.

So over 2500 miles I caught about 3 ounces of crap.

I'm pleased with my purchase and I went with the J&L if your curious.

My opinion but UPR is the best in the business. Unlike J&L they have different catch cans for different brands of vehicles because they all run differently. UPR also has a one of a kind unique system unlike any other system in the business. To each their own because UPR may or may not be in every one’s budget. So I always say get what you can afford. At least you’ll have some level of engine protection.

My question on catch cans is, since you are changing the evac system, how do you know that the changes are not causing the issue that they claim to solve?

Because the gunk in the catch can is not going through the intake itself... it's being separated out in the catch can. The proof is: If you've ever taken a Throttle Body and / or intake plenum off a vehicle without some kind of "catch can" / "oil separator" system you'll notice that there is a nice coating of oily watery crap in the intake. After using a "catch can" / "oil separator" system the intake track stays nice and clean and dry, like it's supposed to.... because an intake is designed to move AIR... not oily mist. Not to mention the effect that an oily mist / vapor has on the air/fuel mixture itself, and on the crud build-up on intake valves and seats.

FWIW I have used JLT products on Mustang platforms for years, and they flat work. On my EB F150 I use THIS... even though the price isn't for everyone.

Well, this isn’t anything new……
When I was a kid, I bought a ‘62 Chevy II, 3 days before I turned 15.

That car had a 194 straight six. It did not have a PCV valve. It had a down draft tube. In the winters, that tube would create condensate, drip and create a puddle with the same stuff that everyone is seeing from an oil separator/catch cans collect.

So it’s nothing new, and that was 43 years ago. So the catch cans aren’t creating anything. They are simply collecting what is there, and what has always been there.

One can either collect it in a can or let it get ingested.

Speaking of, do these trucks actually need a pcv system? Can I just be the dirtbag that pipes crankcase drippings directly onto the road?

A PCV system is supposed to help with emissions compliance.... but in my opinion, I am more interested in pulling a vacuum on the crankcase to improve ring seal, and preventing pushing front and rear crankshaft seals outward. No matter what you do, an internal combustion engine has ring blow-by. You can either vent that blow-by to the atmosphere, or re-burn it. The re-burn (PCV system) at least comes with some benefits of creating a crankcase vacuum. The goal of a good catch can is to have all the pro's of that vacuum, with none of the con's of putting contaminates (oil and water vapor) in the intake track, where air and fuel is supposed to go.

As I stated, just showing the catchings of my catch can.

This is what my catch can has collected in the last 10,000 KM's or 6200 Miles. This can not be good for any engine. I for one, am happy I did install a catch can.

 

[REDRAGN]

Here's mine at 3k miles...totally worth it to keep all this out of the intake and off the valves.

This is exactly why I run UPR’s Crank Case Breather along with their catch can and clean side separator setup. I also run their adjustable high flow PCV Valve because of Boost with my Whipple, I can now run a higher air flow through PCV with the interchangeable jets. Here are all my UPR parts if interested.

As I stated, SOMETHING is better than nothing at all. The goal after all is to catch the blow by. ??
