Are you afraid that an oil catch can will increase the crankcase pressure, spilling oil everywhere? Here is the answer! Check the description as well. If you also wondered what is normal crankcase/engine pressure, here it is.
I was really worried that my oil catch can in my turbo diesel 1.6HDi Peugeot Partner (2007; M59; ~102,000 miles or ~164.000 km) will lead to stress in the engine, i.e. increased crankcase pressure, blown seals, oil will be coming out, etc. This video is a relatively conclusive test that this particular oil catch can (copy of the Mann-Hummel Provent 200) does not increase the crankcase pressure, but others do. For example an universal oil catch can , even with steel scourers does not increase the crankcase pressure, but a mishimoto oil catch can substantially increase the crankcase pressure. The car is similar to a Citroen Berlingo and the engine is the same as in 1.6TDCi (Ford), Volvo, Suzuki, Mini, Mazda3, etc.

The cheap Mann-Hummel Provent 200 oil catch can is MASO (amazon UK): amzn.to/2YIuJ97 or ebay: ebay.us/lpKALx
The kkmoon baffled oil catch can with the bronze filter (amazon UK): amzn.to/3B0HqQt or ebay: ebay.us/3eD5Eg and is the same as the Mishimoto oil catch can (amazon UK): amzn.to/3hK0uYn or ebay: ebay.us/rDu7rX
The universal oil catch can (amazon UK): amzn.to/3IBdA6y or ebay: ebay.us/bKkoB5
The sensor for crankcase pressure measurement is Bosch DPF exhaust pressure sensor (0-1bar) and the part number is: 0281002772 (amazon UK): amzn.to/3H1H8dp or ebay: ebay.us/6tVVqL
The videos explaining how I did the crankcase pressure measurements are here: • Reading absolute press... and here • Reading absolute press...
The arduino code is included in the two previous videos.
The new Mishimoto oil catch can that is classified as MMBCC-HF and the HF stands for high flow (amazon UK): amzn.to/2NiiY3P or ebay: ebay.us/XfrHY1, but it is quite expensive. Here is the Mishimoto website for this oil catch can: www.mishimoto.co.uk/universal... and a bit more on how they designed it: www.mishimoto.com/engineering...
The actual results are here:
Baseline (original intake, no oil catch cans) 1.55mbar
Mann-Hummel Provent 200, cheap steel filter 1.58mbar
Mann-Hummel Provent 200, original filter 1.54mbar
kkmoon (Mishimoto) with bronze filter 6.20mbar
kkmoon (Mishimoto) no bronze filter 2.85mbar
universal oil catch can no steel scourers 2.10mbar
universal oil catch can with steel scourers 2.40mbar

I have the Provent 200 on my petrol Audi A4, and I LOVE it! It's actually an oil/air separator (not a "catch can"), and it has both a pressure release valve, AND an active pressure regulating valve along with two different types of filter materials (nylon screen and sponge), a plastic coalescence screen, and room for an added wad of steel wool to increase coalescence. The type of filter element is really what matters. I'd never use a "catch can". They are overpriced, are nowhere near as efficient as an actual oil/air separator, and having TWO pressure regulators makes the comparison moot. .

very informative...as for In / Out, I also installed mine opposite of what's on the can and wasn't catching much. When I installed per instruction, it caught more oil / water - also just put fine mesh screens (2) in the baffle. I think either way is fine as you either catch the oil / water from PCV or catch before the air re-enters the intake. I also put a steel wool in there..not sure changing to copper scrubber makes any difference (Mishimoto's have "bronze" filter so.. :- )

good morning friends, I am at the stage of diagnosing this engine and spitting oil from the oil pneumothorax onto the entire intake system. I started by replacing the valve covers, like probably each of you. there was peace for a moment. Next came the turbocharger. Of course, while doing this, I changed the oil and cleaned the entire intake system through the intercooler throttles, ending with the intake manifold. This brought only temporary relief until the entire system was filled with oil from the pneumothorax again. I started the next work on this engine by dismantling everything so far, this time a step further on the head. after replacing valve seals, cleaning new camshafts, new valve levers, I assembled this engine, although I know that I will start it again in a moment. I deliberately did not remove the pistons to confirm that the problem was not in the head. For now, it's just a guess, but I think that blow-by in the crankcase that blows oil through the exhaust valve is caused by worn piston rings/cylinders. so if you have a symptom like blowing oil cap, you have a long way to go home. Regards

I suspected the bronze filter would increase pressure. imagine when it gets clogged up, the pressure would be even more I reckon.

Thank you for an informative video, I have one question: I have a catch can with the bronze filter. The catch can is routed from my PCV to an intake vacuum line. The catch can also has a drain valve at the bottom. When the engine is running I have opened the drain valve and i can feel the strong suction. As long as there is suction is it safe to assume that there is no build up in the crank case pressure?

I’d be interested in seeing what vent to atmosphere pressures look like. I can’t find any info online. It might not apply to your vehicle but plenty of people run breather cans

@kevinoneill41

Back in 1990 I saw a diesel engine generator with a 2qt paint can as a catch can filled a course fiber. The crankcase was vented straight to the center top of the can. The lid was perferated with what appeared to be knife stabing holes all over the top of the lid. The can was placed in a larger pan with an oil spill pad on the bottom. 😂😂 my guess is that this was better than venting straight to atmosphere. I had to open the can. What I found was amazing. It appeared to be working quite well. 😮

@proobuio 3 года назад

This is nicely done sir. I was wondering why mishimoto added those fancy bronze filters knowing that it would be add more restriction to the air flow. And im glad this answers it

@13adrian Год назад

I have been looking at the mishimoto mmbcc-hf that has been mentioned as it hasn't got the brass filter it also has larger inlet and outlet I think 27mm

@petermorton2869 Год назад

This oil catch can you are using is not the correct one & you need one that has an external filter on it otherwise you will get too much pressure build up which no good at all Kind Regards Peter

@jplunkett3647 4 года назад

nice testing and explanation ..... due diligence / research is critical in ANY subject matter ,,, thank you ,,, i am now a subscriber based on this video

@Thinkforyourselvz

Thanks mate, as this is something I have been thinking about when I installed a catch can on my 6L LS. This clears it all up for me now.

@kevinm6283 Год назад

The best video and explanation I’ve ever seen. Very well done. And I’ve seen a lot of catch can videos. I run the brass micron filter and ordering the other can in the video right now. Thank you so much.

@fahdismalek7729 3 года назад

thank you so much for exceptional information. i've remove the bronze

@adrpals2324

I've heard bad and good thing about catch cans, especially about the pressure in the engine. Your videos is great and a wealth of information.

@johnmcmullen456 Год назад

Thank you for all your efforts, found it very helpful.

@seanbrennan4447 4 года назад

Great to find a channel that has the same car and age as mine :) thanks

@robh8131

Really useful comparisons. I'm erring on a system for my UK 2 litre diesel that incorporates relief valves to allow 'through flow / bypass' if a filter becomes clogged. But put off by the silly prices of Genuine Mann 200 Pro Vent CC and the Flash Lube CC replacement filters. Many thanks for your informative test.
