Oil catch can

Oil catch can was created by gus2000
From oilcatchcan.com/

“As the EPA and the powers that be mandated stricter emission laws the system was refined more and more ultimately evolving into what we have today. A completely sealed system that uses the vacuum provided by the intake manifold to draw these vapors out, and the filtered fresh makeup air is drawn from the main air intake system and filtered by the main air filter. This results in very clean emissions, but the unintended issues are the detonation or “knock” that occurs when oil is introduced into the combustion chamber that the knock sensors pick up (before we can hear it) and pull timing to protect the engine from damage, and thus reduced power. Another result is the carbon buildup on the valves & piston tops (any techs reading this can surely verify the amount) also resulting in decreased performance and less power made.”

“The purpose of a proper oil separating catch can is to route these gasses through a baffle system that provides the most contact possible with the outer surface resulting in the oil being trapped and removed from the other gasses that do continue on through the intake and are burnt and consumed. It does NOTHING else in ANY way to the engine oil itself….it can’t.”


Homemade oil catch can.

The can







installed on the engine





Testing: after 200 km on the road, and 5 hours in off road



¿What do you think?

That's breathing a lot of oil. I'd be worried as they arent meant to fill up that fast. I had one on my big car and it hardly filled up at all.

I had a v8 in a RangeRover that used to blow oil out the breathers. I piped them al into a 1 Lt oil can. I drove it from Aberdeenshire all the way to the offroad show at Trentham Gardens, had to stop a couple of times to empty the oil back into the engine!

On the 8th Day God made the LandRover -
On the 9th day he swapped it for a Jimny.

Hello, the amount of oil collected is approximately 3 cc



after 200 km on the road, and 5 hours in off road, I do not think that is an excessive amount of oil

Thanks for your appreciations

Are you sure that your catch can isn't causing a restriction and increasing crankcase pressure? with a good engine you should get hardly anything in there, the baffle in the cam cover is intended to catch the oil and only a vapour should be present in the PCV system.
The article that you quote massively overstates any issues but then it does seem to have been copied from a site that sells oil catch cans.

Some Suzukis and a bunch of motorcycles.
