Oil Catch Can working

[Mongrel]

The calibre catch can is just an empty can. The provent has a filter and a pressure relief valve and is designed specifically for the job.

Right... but if the hoses connect back through, there is little chance of pressure building up. I just can't see what there would be $220 more value.

I am going to go and check out the Calibre tomorrow.

If it does not have any filtering inside - that can be easily fixed.

i had the Calibre unit instaled on mine all it has in 1 inlet 1 out let close to each other. pretty simple i put wool mesh in mine after 2 weeks bought a provent never looked back i can see all the oil it catches plus wen u see it person u can see $$ in it old saying u get wat u pay for.

I had a calibre can for a while. I really can't say what went wrong but I ended up with leaking oil around most of the fittings on the catch can. It seemed like oil that was getting out under pressure. I wasn't too keen on the idea of that much pressure on the PCV so i removed it all. I've bought the Provent but have yet to install it. Others have gone the catch can and steel wool approach and reported successful collection of oil but I'd rather not take any risks with something that will be so expensive if I stuff it up.

[Steane]

So why are the Provent Catch cans so expensive compared to say the Calibre catch can?? Can there be that much difference?? They are just cans and filters right??

The Provent is a PCV gas filter, the Calibre is a catch can that you'll have to stuff some steel wool in.

The Provent has pressure relief valves, large diameter piping and a gauze filter designed to trap oil vapour...while the other is a catch can you'll have to stuff some steel wool in.

I think at $200 it's a bargain considering how well it performs it's function and the fact that it does it safely.

If it was $400 I'd still prefer it over a catch can.

[Mongrel]

Well I went to SuperCheap today to check out the Calibre Catch can, and liked it - so I bought it.

This one is solid metal and comes with all the hoses and fittings. It also comes with a sight gauge to see how much oil is inside.

As a port on the bottom which I plan on putting a hose and tap on for easy drainage, and was only $69!

Yes, I will need to put something in the can - steel wool etc, but am thinking on finer grade mesh instead. Should work a treat.

how long should you expect the provent filter to last... they aren't cheap at $88 each

From memory I think it is about 100k.
But I will probably change mine after 50k.
When you look at the price of the other filters, I think $88 is quite reasonable considering what it does and how long it should last.

[helicoptercow]

yea $88 for 100k would be the least of my worries.

So other then buying the kit that comes with the hoses, where have others picked up the hoses from and fittings and what sorta price are you looking we talking? $125 for some pipe and clamps seems steep.

[Homer]

I'm sure I read somewhere that it's not advisable to put steel wool and some other materials into catch cans. Not sure where I saw that though

Sorry V6 hijack of an oiler thread

[Snooozy]

I have been using stainless steel scourers in my can now for 5mths (7,500km) & had no problems, They seem to work well
see here
catch can

almost no resistance to flow & cheap. I have about 1/2 doz in my can.

check build thread link in sig for details

I thought $125 was a bit steep too. So I bought the Provent and then sourced all the hoses and fittings and spent just under$125 for them
It wasn't worth the mucking about, but I did get black hose,which is what I was after.
So the $300 odd that they want for the whole box and dice is on the money.

Excuse me for being a noob - this is my first Diesel...

But I gather that the Catch Can goes between the two open ports you can see in the pic below??

[Snooozy]

Yep, that's the place Mongrel

[Mongrel]

Cool.

I have to say there is bugger all room under the bonnet of these buggers.

The only thing that is a slight concern is the ports on the catch can are quite a bit smaller than those of the triton. Not sure if that will be an issue.

[Snooozy]

best to keep them all as close to the same size as possible to avoid pressure build up in the sump.

You need a good flow with no restrictions to the PCV gases.

[Mongrel]

That is the least of my concern. The bigger problem is mounting. There is bugger all paces to mount this sucker.

[Kegsy]

On the mn there is two choices.

Behind the battery next to the fuel filter, or behind the airbox in front of the brake booster

The first being the better as it should be cooler here allowing more oil to condense out of the crank case gasses

[Mongrel]

OK - Catch can is installed. I ended up installing over behind the battery box. There is a couple of threaded holes on a mounting bracket and it fit nicely. As mentioned before, the size of the nipples on the Calibre catch can is smaller than then the crank case nipples, but I am not too worried at this point - even under heavy RPM there is not a lot of pressure coming out of the crank case - and it can't be that bad as they hose that connected to the crank case could be just pulled off without much force. If it becomes an an issue, I will attach new fittings to the can - no biggie.

I ended up changing the port layout and have the intake coming into the top of the can. I then have a tube connected that goes 3/4 the way into the can, meaning the gasses must pass through the steel wool and back out the top.

The pictures say it all.

Mongrel

can't fully tell from the photos and i have not installed one so take this with that in due regard.....

IMHO i would ensure that the hoses have no valleys in them. in other words from any point in the hose it is either completely down hill to the can or the engine. it is possible that oil could accumulate in the hose valley and block the circuit. obviously the hose pre-filter would be the worst.

[Mongrel]

You raise a valid point, but there will undoubtably be a low point. If you look at the hose that comes out of the crank case it immediately has to rise from the port to get around the back of the engine to the can.

Hmm... Might go out tomorrow and see if I can get better route on the hose.

[mad992]

i think it looks fine good job me thinks

[Mongrel]

Thanks lads,

Question though... was it just the earlier models that would get oil in the Intercooler? I ask because the port that shoves the gasses back into the air system appears to me to be after the intercooler??

Or do I not know what I am talking about - which is possible.

[ag9111]

Its between the air cleaner and the turbo, then into the intercooler and from there into the motor

Yep you got it wrong

Hmm... are you talking about this thing below - because mine is behind the grill.

My hose came straight out of the crank case and into the air system right before the turbo - about 100mm before the turbo.

How does the oil get all the way back to the front of the car to get into the intercooler? Not being a dick... I am keen to find out.
