Thread: For those with "breathy" diesels and oily intercoolers

Just took some pics of my Provent after 15000 Km...

Hi Michele,

All looks fine - should be plenty of life left in the element yet.

Thanks mate!
Mucho reassuring!

So what was the result?

Are these things a must have, just or an interesting idea?

Depends how much you like cleaning your intercooler and replacing your turbo...

There is no harm in waiting till the vent pops, as long as your oil seals are in good nick.

In most situations, the provent should be fine for 1500hrs (multiply that by the average speed you would travel at for km).

The filter should look oily in use. It should slso be fit and forget unless the vent pops.

I only recently fitted my Provent and missed out all the intel,
how do you know when the vent pops ?
I gather you are lab testing the soot in the old elements, in how many klm should the filter be changed & do you still want the old elements ?

Mine is looking like Michels after only 2000 klm,

Would fitting a provent reduce exhaust smoke - I would not think so but my TD5 going flat chat in 4th towing a caravan up the Adelaide hills I was blowing no smoke, Im sure I was before ???

It is normal for the filter to be oily.

When the vent opens, oil/blowby will vent between the two halves of the top cap, so you will get oil dripping from the outer edge of the cap - and the outside of the provent housing below the cap will likely be oily.

Don't need any more of the 200 elements at this stage, however am looking for people in WA with truck/plant fleets to test the provent 400.

It is quite possible that the provent could reduce visible smoke if you have heavy blowby. Engine oil is much harder to burn than diesel.

"am looking for people in WA with truck/plant fleets to test the provent 400".

What about the private urban bus companies?
