provent/catch cans?

I'm not sure how Mitsubishi has done it but they have no or negligible DPF issues. Their earlier 2.5 and larger were prone to carbon buildup though and I can't see that the newer 2.4 woild be different there, hence a lot of owners use catch cans. The service manager of the dealership where I purchased mine and have it serviced reckons the jury is out on whether they are needed in the 2.4 but he uses one on his.

Nice but not always necessary IMO, and there can be potential downsides depending on how you set it up.

I'll write up a bit more later, on my way to a callout atm.

Ok, finally home and having multiple coffees to stay awake. [emoji849]

The bloke I used to use for oil analysis didn't like the idea of draining the volatile stuff caught by the Provent back to the sump.
In Terry's opinion you are better off catching and disposing it.
Those volatile components can potentially be nasty to your oil as they'd include quite a few acid forming compounds.

Ben/isuzurover did a lot of testing for Mann-Hummel including used oil analysis when Mann were first introducing the Provent but I've never asked Ben what he found by using a sump drain on them.

I'll try and remember to flick him a text

Correct,

My son has a Provent on his LC76.
I have checked it a few times and there are often visible water droplets in it,from condensation.
So putting whatever is in it, back into the sump would definitely be a bad idea.

Couldn't agree more Rick. The stuff it catches smells off/acidic and looks nasty (technical term). My Provent bleeds off to a hose with a stainless tap. I remove the caught watery crap oil and I am glad it doesn't go back to the sump.

It's the same with petrol engines and indeed I do not return it to the sump. I have a long 1" line going all the way down to the chassis close to the oil filter where I have fitted a ball valve. It has enough volume that I only need to tap it off during an oil and filter change. What comes out is usually more like stained water then oil. I do suspect this goo to clog up the filter more rapidly. Any thoughts / experiences on that? Further, I know it's a landrover :) but my car started leaking profusely from all seals at one point and I have since run a few k's without a filter element in the provent and the leaking has largely subsided. I am not sure how long they are supposed to last anyway? I think I had the provent mounted for 30K's or so (with the same filter element)

Cheers,
