Catch can


Deverall. my recollection on catch can for lc200 is that from 2017 ?, it was in doubt about fitment, the Provent had been redesigned so that the in and outs were reversed and fitment could cause over pressure in wrong places.

And of course we cannot access lcool.

 As LCOOL has now been down for over  5 months I think it is gone forever unfortunately.

G'day Chaps,
Until I bought our GU Patrol, I hadn't heard of a catch can. The previous owner said there was one fitted - to check it every now & then. It was a simple affair, a plastic can fitted in series with the feed from the crankcase breather to the intake manifold. Inside there was a fine metal grid that was the filter. I used to find about 5mm of oil in it at every service.
Not long before I sold the car. I noticed the air intake hoses had a slight oil coating on the inside of them so I new the can wasn't perfect. I also had friends who had major problems with their Pajero, requiring an expensive rebuild. And after spending thousands on the engine, they traded it in on another!

When I bought the D-Max, the dealer suggested I have one fitted by them at my expense - I declined their offer but did some checking into the issue. I found Isuzu trucks with a similar sized engine had one fitted as standard & filters were a fraction of the cost of Provent ones. I contacted Isuzu Truck in Townsville to see if there was a kit available but there wasn't. Just after I received a threatening email from Head Office of Isuzu Ute saying they would have my warranty cancelled if I went ahead with the modification! So I replied, saying my dealer had recommended a catch can - heard nothing in reply. At 13,000kms, I bought one & fitted it myself. I have a 1.5L milk bottle that is almost full of oil that I have emptied out of the can - in 70,000lms - oil that would have been gumming up the engine's insides!

The Provent 200 can, filter are not cheap but I got a good deal from Western Filters in Sydney, saving me some dollars.

For those who question the fitting -
1. It's insurance against an expensive repair - imagine if you were broken down in a remote location the cost of recovery.
2. Dealers, manufacturers are there to sell cars, spare parts - not to preserve them.
3. Owners who remove the EGR system make their cars unroadworthy by doing that if you have an inspection done for some reason.

 Not sure Craig. Would need to check on a forum that cannot be accessed. Lawrance contacted me the other day. No real

progress on LCOOL as yet but there could be a maybe. A real shame as there's so much information there.

 Excellent post Warren. Precisely what I was trying to explain. Gumming the engine's insides.

I too am using a plastic bottle to collect the oil. Prior to that I had a length of hose that ran from the front to the rear of the car.

Found that a plastic bottle to be more practical. On some stationary engines, it is common practice to redirect the proceeds of the

catch can back in the crankcase. Given the setup, the oil collected is clean enough to go back in and also dispenses the need for

the collection vessel to be checked and emptied.

Shame a bout the Isuzu's attitude. Some members of LCOOL have also been threatened with cancellation of warranty.

Proper Design - RE: Catch can


My 20 year old BMW M57 diesel has a properly designed vortex oil separator integrated into the PCV housing.  No need for a catch can.

When I deleted the EGR at 200,000km there was only a mild carbon build up around it and the tuned-length induction ducts that followed it only had a tiny sheen of liquid oil inside.  To complete the delete the EG cooler and its thermostat had to go too with plugs fitted into the cooling hose stub ends and that improved the already great cooling on this legendary engine.

Why is toyota still using 1920s technology?

bye.

 Good German engineering. What Toyota is doing or not doing only they know. Maybe pressure from the accountants

to get the job done quickly. Interested to see if the new Landcruiser is in need of a catch can.

At the end of the day, as per your fine BMW example, a catch can (race vehicles excluded) it is a bandaid fix to

 a flawed design.

Pros and cons hey....Regardless of costs I don't see any info from Toyota supporting a catch can. I doubt that Jeep does either.

Here is an excerpt from a Toyota dealer asking for great caution and a good look at what you want to do. It is not a head over heels get a can from this company at all.

I am no way getting involved, but my 100 series turbo has just had the valves etc shimmed and done, and without a catch, can is in perfect nice since new from 2004. As an observation though you may notice that it is only the sellers of these cans that advocate them. I reckon there is a possibility that a good can install may have no detrimental effect and may not do any good either. I would need a very good test done by top level service folks to get the desired info.

So this is just food for thought not an out right disapproval. Just stating so things to look out for.

https://www.maroochydore.kenmillstoyota.com.au/blog/will-installing-a-catch-can-void-my-toyota-warranty/3653/

So what can go wrong?

Catch cans have filters that vary - from steel, fabric, or even nothing, so they are not all made equal, and some are just an empty can. Not ideal. Catch cans can fill up or block, causing back pressure on your engine if they do not allow the perfect amount of air flow. They can retard spark timing and cost fuel economy and power. Another devastating outcome is damage to your engine.  

Does a Catch Can void warranty?

Installing aftermarket parts can compromise your Toyota Warranty Advantage. All Toyota parts are tested to be the perfect fit and will enhance your Toyota experience because they are tested and developed to warranty standards to fit, and work in conjunction, without compromising your genuine Toyota Parts already in use.  

Aftermarket parts can void your warranty if they cause pressure, or worst case, damage to your Toyota engine or genuine Toyota parts. Warranty Coverage will not apply to damage caused by modifications carried out at a non-Toyota repairer or failures in non-genuine parts and accessories. And if the catch can causes damage to your engine by restricted air flow, your warranty will be void.  

Hold onto That Feeling and your Toyota Warranty Advantage

Catch Cans are designed to trap and deflect excessive oil residue from choking an engine. Your Toyota Warranty covers any issues that may cause excessive oil residue in your engine.  

Love your warranty? Then do not let the can catch you out!

Paul, first of all I cannot comment on the 100 series as I do not much about them.
Secondly, if you knew anything about the VDJ200, you would also know that the oil comes
from the cam chain which throw oil directly at the PCV outlet.
This in turn causes said oil to find its way in the intercooler.
In the mains, Toyota don't know a great deal about the VDJ200 other then the official
Toyota spill.
Offcourse they will tell you all the bad things about a catch can on a VDJ200 but how
many of them have seen oil in the intercooler. How many of them can tell you the
number of turbo failures - one is more prone then the other. I do not remember and
not having access to LCOOL I cannot verify this.
A quality catch can such as a Mann Hummel will not cause any problems.
May I suggest that you do not buy a 200 series Landcruiser with a V8 diesel as it
will give you so many problems you are guaranteed to go broke.
Google info before making unsubstantiated comments. If you cannot because of restraints,

talk to a reputable diesel company like Berrima Diesel who have no affiliation with

Toyota or Mann Hummel. They will not give you the BS Toyota dealers are renowned for.

Lets face it, your garden variety dealer workshop is nothing more the a gathering of

grease monkeys who will one day call themselves mechanics.

What makes  Berrima Diesel the authorrity on all things diesel, they are like any addon business, they will pee in your pocket to extract as much of your money from your wallet, under the guise of making your vehicle operate better.

 I know SFA about LC 200's, but many people on here fit Catch Cans to a variety of vehicles suggesting the inlet manifold is caked in crap that a catch can will solve.

First hand experiance at 110,000 km I had a timing belt tensioner fail that caused 11 bent valves in the head, while the head was being rebuilt by the specialist, the mechanic ultra sonically cleaned the inlet manifold system including the EGR. When I collected the ute the mechanic suggested I should get better fuel economy now that inlet system had been cleaned.

Alas that was a furphy because prior to the repairs I was getting between 8-9.5l/100k and now at 260,000k I still get the same fuel consumption, and when towing in good conditions I get between 13-15l/100k.

So how would a catch can work for me ?

Well Gundog, 

First of all a disclaimer: I have no association with Berrima Diesel and only refer to LC200s specific.

For all other makes, you will need to do your own research, however the basics are true across the board.

 

The mechanic was not entirely wrong as by method of deduction a cleaner manifold should allow for better

breathing. A caked up manifold has restrictions from the soot build up. Bit like trying to breath through a straw.

Failed tensioner has noting to do with a catch can, however, if this was a Toyota they would deny you a warranty claim

if you had one fitted.

Fact of stealership. The two only things they are good at is taking your money and providing crap after sale service. 

 

A catch can will help to minimise the build up of 'soot' in the inlet manifold. Soot is prevalent in diesel engines

because of the oily fuel as opposed to the dryer petrol fuel. What will help more then anything else is the deletion

of the ERG valve. This gadget recycles HOT exhaust gases in the inlet manifold. Heat + exhaust soot + diesel fuel

and you have the recipe for a caked manifold. You will find that a lot of ex-mining vehicles suffer a lot from that 

because of the amount of time spent idling.

Not encouraging anyone here to go and delete the EGR valve as it's intended purpose is to reduce exhaust pollution

from gases unable to burn to completion at low engine speeds.
