Default hoses for oil catch can - 08-04-2017, 01:48 PM

Anyone know the diameter and sizes of the hoses needed for an oil catch can? I picked one up but it didn't come with the hoses. Thanks!

The high side were 3/4" although I got mine with the OCC from BMS. On the low side I think they are 1/2". I got the plug and play BMS PCV delete and bought the Mishimoto OCC and hoses separately.

Thinking about getting a second BMS OCC plug and play for my other BMW as it does scavenge a lot of oil that otherwise would be going into my exhaust valves. To me it was a good investment.
