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 sensor for crankcase pressure measurement is Bosch DPF exhaust pressure sensor (0-1bar) and the part number is: 0281002772 (amazon UK): https://amzn.to/3H1H8dp or ebay: https://ebay.us/6tVVqL
The videos explaining how I did the crankcase pressure measurements are here:    • Reading absolute pressure with Bosch ...   and here    • Reading absolute pressure with Bosch ...  
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): https://amzn.to/2NiiY3P or ebay: https://ebay.us/XfrHY1, but it is quite expensive. Here is the Mishimoto website for this oil catch can: https://www.mishimoto.co.uk/universal... and a bit more on how they designed it: https://www.mishimoto.com/engineering...
