Don't see how that would make a difference to be honest. The soot particles are tiny and are comprised of mainly carbon, nitrogen and oxygen- The soot itself can't be that abrasive as turbos handle it fine in older engines with no EGR- you'd see pitting and premature failure of the impeller blades if it had similar consistency to something like dust or sand.

I'm still confused though. LOL, Should I install a catch can?

Hey
I'd say do it mate. My take on it was that the egr spits out particles and the vent spits out oil, what you end up with is a thick goo in the last part of the intake manifold.
Your turbo gets oil in it, as does your intercooler. how much a problem that is i dont know but seeing as the intercooler is meant for air, not oil, over years of it passing through it must take it's toll. surely.
I pulled my intake apart and cleaned the crap out after i installed the can. the goo is gross and hard to remove. took a night of soaking in cleaning products that melted my gloves. thats how you know its the good shit. hahahaha
If you put a catch can in, pull the springs out of the valves and stretch them a little bit. They have a tendency to flutter under load and you'll think that your engine is about to meltdown. I know i did.
heres my clean if you want to see the details.

I would base your decision more on how long you plan on keeping the car for. Toyota don't think it's necessary as they only warrant their vehicles for 3 years or 100,000km not usually enough time for the oil and soot build up to be their problem. If you plan on keeping the car and putting a number of km's onto it then I defiantly think it is worth adding a catch can as the biggest benefits of having one are going to be seen over a longer period of time.
If you think you'll keep the car to do a few trips to trade it in once you get bored of it not long down the track or till you can afford a 200 series or dual cab cruiser ute then I wouldn't worry, I would just give the intake a one off clean if it has already done a few km's then get your use out of it and move on (unless you want it to help with the resale).
Like B1 said putting a catch can in will stop oil going through your whole intake system eg turbo, pipes, intercooler, and intake manifold. The EGR which contains all the soot particles only passes through the intake manifold so has a short distance to travel only passing through the intake valves and into the combustion chamber where it then mixes with oily diesel where it then transforms to that same soot anyway (if abrasion of the soot particles are of any concern).
Not having the catch can allows all that soot and oil to turn to sludge making it take longer for that soot too pass through the system if at all. If you just block the EGR you still have the problem of oil coating your whole intake system and mixing with clean air and fuel. Ideally I'd do both but then you have the legality issues.
I personally put one in as the problem of oil through my intake was one less thing to worry about, I'm under the belief that vehicle manufactures do it the way they do as they can't just vent it into the atmosphere due to pollution control and it means it's one less thing to service so the best solution is to just cycle it back through the intake, I don't think it is to serve the purpose of lubrication, just a way of dealing with a waste product cheaply. Therefore adding a catch can is a better way to remove this waste product allowing the engine to still function normally and more cleanly while keeping the dolphins happy.
As for installing a catch can its a pretty simple task and plenty of kits available that cover all the brackets and hoses, just make sure you get a reputable one so you don't run into problems later on as you have already noted.

I installed the Western Filters Provent 200 kit on my 1GD Prado a few thousand kms ago. The filter is slowly accumulating oil but not enough to run out the drain as yet.
Condensed water is another thing though, the 400mm or so of drain tube was completely full of water yesterday. I can see why manufacturers don't install them as standard if they require constant observation/draining - it would need an automated system or warning light. Feeding the vapours back through the engine is much simpler.

Yes I have endured that video. Cant stand that guys bad jokes and style. I didn't really get anything from it. Yes people selling catch cans want to make money but then again, so do people selling oil. Doesn't mean I won't buy oil.150 GXL - ARB bar, Winch, 9" spots, rhino rack, 32" LED bar, Snorkel, 2" lift, AT's, Dual batts, UHF, 40L fridge, KAON cargo barrier - rear door table

I installed a Western Filters Provent 200 kit 5 days ago. The car seems to drive the same as before, but I have seen a noticeable drop in fuel consumption since the install. For the past 4 weeks I have been averaging 13.5L/100km (lots of city driving), but since the Provent went in, it has dropped to 12.9 L/100km. I am confident that it is a genuine saving because I have been driving the same route every day. I have not collected enough oil/water to drain it yet, but so far the fuel economy improvement is a major advantage to me.

new to pradopoint and wanting some advice on egr and fluid loss in the cooling system, how do I post a new topic / thread?
thanks in advance

Hi
I am unsure of the posting process but assume you will be able to read this and post any advice….
My 2016 Gx Prado is loosing coolant slowly over time and have had all radiator hoses etc pressure tested and have concerns it may be a leaky egr or worse, any experience or advice welcome as I am nervous about long term or significant engine damage
regards
Matt

Hi surfdivefishcamp,
Look for bullet point 15 at the bottom of this link as most likely your issue and matches your year so should potentially be able to rattle Toyota's cage to get fixed under warranty as a known defect.
Toyota GD series diesel engines (toyota-club.net)
Anyone else this link has a great write up on how the 1GD-FTV works and all its known issues.
Regards Phil
