My Provent install on a PD engine.

For those (like me) who were unaware of this product and how it works, here's a link:

Looks just the thing for those troublesome MK1 diesels that "run away". Not a cure for the problem perhaps but a good delaying tactic!

Does anybody have a competitive price and the name of a supplier who will mail out?

Nice work, you've plumbed it well. Always tricky to work with the two vertical inlet and outlets on the engine. I hope the tubing and elbows withstand the heat though!

The provent is a decent size, which again is half the nightmare.

You'll be amazed how often you have to drain it!

elbows are about $1.50 each, and 1M of 25mm hose is only $5.

I'm looking at making up some heat shielding to shroud the hoses from the turbo heat, this should extend the lifetime of the joinery exponentially.

one thing I've realised is when the car is stopped, the rear of the air intake just sucks in the heat from the aircon+intercooler+radiator thermo fans.

This probably works well in cooler climates, but in Australia on a 38C day, the last thing I want is 38C+aircon+intercooler+radiator heated air being sucked into my air intake prior to the turbo.

this must be a killer on the overall engine performance.

Nice instalation. Did you think about getting silicon hoses? Plastic one will brake down over the time.

at this stage I'm not overly concerned with the stability of the materials as I will be frequently inspecting the unit over the next 5,000 KM.

hose selection was more of a 'lets see if I can get this to fit under the bonnet without having to chop up my stock CCV breather tube'.

moving forward I am scouting to find:
A good quality oil and heat tolerant 25mm hose.
25mm copper or brass elbows.

out of the 3 Bunnings I went to only 1 had 25mm copper elbows and they were out, the others didn't stock them unfortunately.

I will also be looking to replace the mounting bracket with a sturdier design that the battery sits on top of.

the hardest part for me was not having a 12V backup rig to connect to the car, if I did I could remove the battery to get easier access to the hose connections.

Let me know if you find anything hose wise, as I went to a hose specialist, and there was either HUGE, of the rather unflexy, tough as nails hose I have at present. Rather hard to work with! Cost a bit too!
