UPR Catch Can Install

Im going to sound like an idiot for asking this but,...what does that do for the performance?

There is no HP or Tq benefit but a catch can will help prolong the life of the motor by reducing oil & contamination in the top end of a direct injection motor.

It begs the question why Ford didn’t include this as part of the emission system.

FYI — any modifications to the vehicles emission system may be grounds for DMV to fail a vehicle's inspection. YMMV

answer: how many people do you know who nevet touched an engine or couldnt install a kn filter for their lives?

remember all those leased germans with neglected and abused engines? Thats why, though it should of been an option like a winch.

also, my last upr had a drain valve, how would I empty this one?

this really isn't necessary on the second gen 2.7 as it has direct and port injection so the carbon issue on the intake valve is no longer a concern

Yeah. As long as they can stop the engines from blowing up.

Bronco 202?

Yeah. As long as they can stop have the engines from blowing up.

really give me a break there will always e a few failures

I've never been sold on oil catch cans. I'm not sure why. I dislike this one on how long the hose is to the can. Our engines are already pretty cluttered.

No performance benefits using a catch can. There are no benefits whatsoever for the 2.7.

engine longevity, since it captures the gunk oil

Ahhh catch cans….. as someone who has been driving a Kia with a GDI engine for 116k miles I really wish I had one but the Kia warranty has enough loopholes as it is so I never tempted fate with one. As far as functionality of one here is my amateur, not an engineer, not a certified auto technician, just someone with a pretty good understanding of physics, thermodynamics and internal combustion engines, opinion.
On the 2.7 with both direct injection and multi port injection the benefits of a catch can will be minimal at best, same for any engine with fuel added before the combustion chamber via multipoint injection, throttle body injection or carburetor.
The 2.3 being solely direct injection (which I am a fan of for the balance of economy and power) an oil catch can could have a lot of benefits for reducing maintenance costs and minimizing power loss as the engine ages.
How does a catch can help? Well for that we need to dig a little deeper. All internal combustion engines generate pressure inside the crankcase. Be it from thermal expansion as it warms up, off gassing of oil as it breaks down and piston blow by. This pressure has to go somewhere or the engine block will quite literally explode. In the early days this was simply vented to the outside and all was good, until emission controls came along. With the advent of emissions controls you could no longer vent those gasses that contain aerosols of oil and leaked combustion gasses into the atmosphere. The solution was to add a Pressurized Crankcase Vent (PCV) valve to one of the valve covers and feed the gasses back into the intake air stream, some people would still bypass this with a small air filter directly attached to the PCV but I personally see no performance reason for it. This system worked relatively well by allowing those gasses to be burned and passed through the catalyst in the exhaust system to be neutralized. Then comes the advent of Gas Direct Injection (GDI) which has evolved into a good system that allows the computer to accurately adjust the amount of fuel injected into each cylinder, as well as the timing of fuel injection depending on how much power is being called for at that exact moment. The single biggest downside of GDI, well that is the aforementioned PCV system. On other fuel delivery systems there is a constant flow of fuel atomized in the intake air which passes over the intake valves on each cycle and helps to cool, clean and lubricate the back side of the valve which reduces the amount of oil vapors and other carbons introduced by the PCV that may stick to the backside of the valves. So what? you think. Well having that oil and tar and gunk on the back of the valves impedes the airflow into the cylinders, thus reducing the power the engine is capable of making and if left untreated can build up to the point a valve may not close properly leading to a dead cylinder.
To get around this problem someone came up with a catch can in between the PCV and the intake manifold. This device is a place where the air containing those gasses from the crankcase has a chance to cool down and let some of the impurities condense and remain in the can. This in turn reduces the amount oil vapor available to stick to the intake valves and become carbon build up. Now no catch can system is perfect so some oil does make it through so routine cleaning of the intake valves is recommended but with less oil in the airstream there will be less deposits to clean.
Hope that clears up some of the “why” in catch can discussions, the “should I?” Will depend on you, and your preferences. For me having ordered the 2.3 I plan on having a conversation with the service manager at my dealership when it comes in. If it’s not a major risk to the warranty I will be installing one, if Ford says no then I will be cleaning my intake valves every oil change again. Hope this helped at least some people.

That's a wrong thought, reason being, during the 2nd stroke (Compression Stroke, occurs some during combustion stroke too) the compressed air/gas mixture leaks down into the crankcase gets whipped around and mixes with minute oil droplets. Then that mixture goes up through the passages and goes through the PCV (should be PDVC, Positively Deadly Crankcase Ventilation), this is routed back to the intake to be burned, in reality, coating the engine with the oil in that gas. This occurs on new engines as no engine seals 100%, there is always a certain amount of leak down allowed. This also occurs more on Supercharged and Turbocharged engines more than naturally aspirated engines due to more pressure from the power adders.

Catch can is one of the best things you can do to help keep the engine clean.

If you order the catch can from UPR, they offer a drain kit with a ball valve. Comes with a hose that you cut to the length that you want and makes it super simple.

WHAT?! The PCV hose is on the top for the 2.7L? Jealous.

On the 2.3L is it down the side and you have to remove tire and most of the wheel well to actually get to it.

Wrong., during the 2nd stroke (Compression Stroke, occurs some during combustion stroke too) the compressed air/gas mixture leaks down into the crankcase gets whipped around and mixes with minute oil droplets.

True, but gasoline is a natural cleaning solvent, and since the 2.7L is port injected, it'll get the benefit of the gasoline continually cleaning the intake manifold/intake valves... preventing the oil build-up over time. You can also use various additives to your gasoline to help keep the intake clean.

The 2.3L, however, is direct injection, so you don't get any of that natural cleaning from the gasoline, and the PCV will gunk up the intake side of your engine over time.

In my opinion... a catch can on the 2.7L is a nice-to-have. On the 2.3L I would almost consider it almost mandatory if you want to ensure the longevity of the engine. The only reason why I don't think it is strictly mandatory is because you can technically just take apart the intake manifold on the engine and clean it out manually. But that's a pain, so I personally would always put catch cans on direct injection engines.

for the 2.3 this makes sense, but not really needed for the 2.7. It probably can't hurt though

Great breakdown, thank you for your post. Nice to get A worthwhile one!

Thanks, may not know much about Broncos yet but figured I should share what little knowledge I do have lol

Almost everyone I knew who owned Dodge Challengers insisted on getting one of these installed on their engines. They're clearly useful additions to the engine compartment. You just have to make a habit of checking the can every so often and dumping it into a waste oil container.

It is available from multiple part sites, so I would take a moment to shop around to ensure you get the best price.

BUT, here are the links for the manufacturer's site:
