Anybody know, of a good quality oil catch can that actually works, that I can use on my 105 Series Landcruiser?
I am trying to stop as much oil as possible, getting into my nice new intercooler.

Noel,
I can vouch for the mann-hummel catch cans. They are an excellent product.
Cost more but they are worth it.

Thanks Rockape,
Just had a bit of a read up, seems to be the go I think.
That is three recommendation's, so can't be too bad.
Better than the pretty tin cans I have seen in speed shops, with Mums, steel washing up scourer, in the bottom. LOL
Cheers,

G'day Noel
An engine will run for many thousands of km with the blowby amount as normal, and the oil mist will lube intake valve stems and upper cylinder to some extent.
Oil mist through an intercooler is normal and not usually a problem.
If happening at a high rate it may cause some trouble.
Firstly the oil used in the engine may not be sealing the rings very
well and this allows lots of blowby which fires oil mist out of the engine at a far greater rate than is normal.
The oil quality is by far the most important thing to consider. If it isn't one of the top 4 brands which are world recognized then you might
well have trouble.
Synthetic or semi synthetic may give vastly improved oil control and lessen blowby just by having good performance characteristics.
After these things are considered then you might need a catch can if all is out of control.

Thanks for your reply
Ross M,
I don't have a blow by problem, all is quite normal.
I just think if I can separate the tiny bit of oil mist that is in the air, my intercooler will be a lot cleaner.
A teaspoon in 10,000ks is not uncommon, but I would rather it in the catch can than my intercooler.

hi noel
wouldn;t it be better to stop the leak than try and catch the oil
or is it one of those toyota lc inherant problems??

Hey Mazcan..., your not related to Catch by any chance?
Nah, it's not a leak mate, it is the small bit of oil mist that is mixed in with air that comes from the breather out of the tappet cover and then goes back into the motor via the air intake.
This is not a problem but if you have an intercooler this air comes in before the intercooler hence you can get a build up of oil in the cooler over time.
The catchcan captures the oil and you can empty the can back into the motor if you like.

Hi Noel
I would second the Provent 200 as
well, after some research it is the best I came across and in fact just ordered one this morning off ebay.
Also agree that you need a catch can to keep the intercooler and intake ports/valves clean. The main reason blowby is fed back into an engine is to cut down on pollution.

G'day Chris.
I agree, most/all engines suck up the blowby for pollution reasons. For most engines the amount of oil going through to the cylinders as mist is not a problem.
Millions of kms are done by engine without catch cans. It is just if it is a problem, then yes, spend the money.
Don't know why the double post. Haven't selected submit twice.

Thanks Chris,
Just had a read up, reckon it's the best I have seen to date. Checked ebay, $152.22.... not bad, considering it should work.

There is quite a write up on the newtriton.net
forum where the Provent's are creating a bit a back pressure when the filter gets coated which then pressurises the engine crankcase with a potential for leaking past seals.
Modifying Provents
I built my own catch can for my Pajero using fittings no smaller than factory original and the catch can large enough not to create back pressure problems.
As the pics below show the oil/air mist enters the can then has to filter through the scouring medium before then being fed back into the inlet upstream of the turbo.
It works as I designed it to, it catches all the oil leaving the inlet to the turbo dry as it should be.
At intervals I just open a small valve at the bottom and drain the captured oil and condensate.

I fitted the Provent to my 1hd-ft motor 3 years ago.
Intake tracks & intercooler have been free from any oil residue ever since.
I don't recommend that you tap the return line back into the sump.
I drain the return line when changing the oil & it collects about 30mil of oil between changes.
I've replaced the filter once.

Thanks Andrew,
Looks like a nice neat job mate.
Thanks Hamo,
I would probably do the same as you and drain it at oil change time rather than pipe return to sump.
One filter in three years ...that can't be to bad.
Thanks fellers,
