Thread: Provent opinions

I fitted one recently, They definitely work in removing oil, but I also got rid of the EGR valve as well.

How/where did you mount it?

The current generation of Provent filter elements should be able to remove at least 95% of the mass of oil mist. Likely closer to 99%.

I mounted it on the rear LHS firewall. I found a picture of a bracket in the stickies for Provent's in TD5's someone had designed. I can post a picture if you want.

I think that might be LandyAndy's version.
I have pics of his and IanP's but with the doc at 2.7MB, would have to email to a normal address - too big to post here.

Thanks but my dual battery is over there. Not much space left under bonnet being an D2a HSE with all the options.

I am slowly searching the posts on this forum re how best to plumb the PROVENT but haven't just yet noticed a definitive or recommended approach. Personally, whether i go for a PROVENT or not largely depends on understanding if the TD5s 'positive' crankcase ventilation installation will be compromised leading to increased crankcase pressures and subsequent undesirable consequences - or do i have an over active imagination...?

Installation on a TD5 is very simple. The drain can T into the turbo drain, and the existing 19mm vent line from the tappet cover just gets lengthened to go through the provent.

The provent has a valve in the cap which vents to atmosphere if the crankcase pressure gets too high, so there is no way the crankcase can overpressurise unless the valve malfunctions.
