    Crankcase ventilation.

    Hey Legends new to this forum and was trying to chase info on crank case ventilation.

    Ive got a 25 d350 and im planning on keeping it atleast ten years, im putting in a larger pwr intercooler and an auxiliary trans cooler because i tow a 2 ton camper a couple of times a month, ive put about 20,000kms on it since I got it 6 months ago.

    Every modern vehicle ive owned ive externally vented the crank from the lowest point possible with a reed valve, one way valve, because im not a big fan of gases re entering my intake but there are other benefits of scavaging aswell.

    Has anyone done an external vent or knows of who has, I can't find any info.

    Thanks

    I can't answer your question but have you looked into disabling EGR as generally, exhaust gasses combine with any oil vapour to clog the inlet tract. However the interaction of EGR and DPF burns could mean that disablig EGR isn't an option on these engines.

    IMO towing 2 tonnes with a D300/D350 shouldn't require any modifications.

    Doing those sorts of mods may/will also be an issue while the vehicle is under warranty,in case it has any warranty issues,no matter what the issues are.

    Also same as Graeme has said the vehicle should easily drag that sort of weight around with no mods.

    I tow a 2.8 t viscount with a 225 D350 with no problems, last year up Darwin/Kununurra areas the engine never went above normal but not sure of the transmission temps though. The D350 handled it with ease.
