  1. Provent 200 - catch can that works 4 Star Review

    Posted by on 30th Jan 2019

    These cans do what they say due to good design and generous 25mm id ports for hoses. Having relief valves for both crankcase overpressure and for coalesing filter element blockage proves attention to detail. I have collected 30mls of oily crankcase blowby residue in 3500kms on a Navara NP300 2.3L single turbo. Engine had 18000ks on it at time of Provent 200 filter fitting. Never put this condensate back into engine if possible; it contains burnt lube oil residue, soot and moisture all nasty stuff that got past piston rings. Suck out condensate or fit a drain hose and valve.
    BTW major diesel engine manufacturers like Cat and Cummins fit Mann Hummell Provents to some of their engines as genuine OEM supplied parts.( marine engines especially in white boats) Prices I find at Sydney Filters are keener that most others for same item.
