Don't forget the removal of moisture and unburned fuel. If the turbo charger feeds the cylinders and the PCV system purges the crankcase, then the catch can IS actually downstream from the turbo. The PVC system is not only relieving pressure from the crank case, it is under vacuum from the intake system. People waste lots of money on lots of things. The money spent for a quality catch can (correctly installed) is trivial by comparison. With or without a catch can, by the time there is an engine problem, the warranty is long expired and the manufacturer of the car will not even talk to me. I am keeping mine in place.
I have run catch cans for 20 years. Trucks crankcase filters that work the same way and vent to atmosphere with filters in them. Less oil vapor in the intake the better and less intake clogging. My latest Triton has had one since. 221000 now. Drain it every 5 thousand KMS so the filter isn't submerged in oil and change the filter as recommended. Provent has a safety valve on it to protect from increased back pressure or engine crank case pressure. Valve guides are still lubricated because the valve stem seal is designed like that. Manufacturers don't want you to run them because your engine will last longer. Less EGR and intake problems. Big thing is to get a correct one suited for vehicle. Not a eBay special. This bloke is getting paid for this by manufacturers. As long as manufacturers get them out warranty and that's or they care about.
Brutally true…I’ve removed mine altogether as the other stuff is done and I was not catching squat so better off keeping it factory on that side of things to eliminate any issues from having one.
Some are true but it always depend on how you install it. I have one because my engine needs it. Its a close system on my engine. Originally pcv hose goes to intake turbo. And my engine gets too much oil that it rattles when getting oil on my engine intake..but when i gave it a try to put catch can where same principle applied which is closed system having just enough hose distance and not too large can, not too heavy buffers just enough air flow..it worked perfect and the engine runs better than before. So for my opinion it's effective aslong as you know what you're doing. Btw, 4jj1 is my engine and had very high pressure crank case.
I've seen loads of CR diesels pooring oil out the injector seals rocker covers ect. Few very close to fires due to restrictive catch can, I don't run one on my diesel take away the diesel soot from the intake and your good
IMO egr soot will do damage without some oil vapour. Like sandblasting the backside of your valves and seats. Oil is the only chance a direct injection (diesel) engine has to keep the valves clean..
Toyota consistently overfill engine oil when servicing my Fortner. Could that be making the DPF problem worse, as the excess oil tends to find it's way past seals and into the recirculation system?
hi for a given engine size Non turbo vs turbo the turbo unit will have BIGGER ring gap. The turbo ver has more blow by . Oil in the intake lubes the valve guides . Excess oil and egr soot is not wanted . . Having a catch can lowers the contaminants a DPF has to deal with . Some vehicles have them fitted from factory .
A breather can works for me but it's messy.. I did have it going back to the turbo/intake but I was still getting oil through and losing power. I just have one filter on the can again. Might add another filter to the can or another can in-between.
Catch cans are legal. Turning off the EGR system is not. So your theory is not legally correct. Cummins and Volvo still make engines that vent to atmosphere so what does that tell you?? Fit a correctly sized can and fit it the correct way and no issues.
Hi, I have a 100series Landcruiser 1HDFTE. It has EGR valve delete, do you recommend a catch can? It runs extremely well and does not blow smoke or use oil, 365000ks .Thanks Peter

Finally something truthful being said about catch cans ! Bravo

How did you plug your rocker cover once removing the hoses for catch can?

Didn't realise this video was 3 years old 😂. My opinion still stands

Me watching this 2 weeks after installing a catch can because i thought it would solve my diesel issues
And it will. The manufacturer of the Provent Catch Can know what they are doing.
A breather can works for me but it's messy.. I did have it going back to the turbo/intake but I was still getting oil through and losing power. I just have one filter on the can again. Might add another filter to the can or another can in-between.
Very well said mate

Fit a correctly sized can and fit it the correct way and no issues.
Yeah, agreed.
Can confirm 👌
My dealership encouraged a catch can! Haha. This is kind of comical. Watch out for the kinks in your can!
Hi, I have a 100series Landcruiser 1HDFTE. It has EGR valve delete, do you recommend a catch can? It runs extremely well and does not blow smoke or use oil, 365000ks .Thanks Peter
Any Oil from the Turbo is almost always because your 1VD-FTV has a stuffed Oil scavenge Pump
Any part on a car could be wrongly installed. That is a straw man argument.
I tried searching for the tsb from Toyota can you share?
What do you do with the rocker cover once catch can is removed? Is there certain plugs to put where the hose was?
Just reinstall the short factory hose that was removed during installation.
I blame the idiots who thought it was a good idea to burn crankcase emissions rather than venting them.
Saying a correctly installed catch can is basically pointless loses you much credibility.
