Oil on air filter and lots of oil in catch can
After our Tallarook run I found a fair bit of oil has leaked out of the catch can through the tap somehow. circled below. Hard to tell how much oil has actually leaked out as I only spotted it the morning after. Fair bit was on the suspension below and a small puddle on the ground.
Attachment 43295
Attachment 43296
So I took the catch can out completely to re-tighten everything, and re-mount properly as the catch can was sort of just sitting there loosely. (catch can is still out of the car, pipe re plumbed to factory conditions. )
Today I thought I'd clean the air filter and found a rather large oil stain/sludge build up on one side of filter.
Attachment 43297
Unsure how long this has been there for. Could well have been from after that run and may have something to do with the leaking catch can, and it being loose, bouncing around on rough track and sending oil splatters up the air pipe through filter?
As far as I know, oil on filter could be by blow-by? And slightly alarming amount of oil in the catch can is caused by.. ?

That oily looking stain is standard fare. Air filter paper seem to be slightly impregnated/oiled. The stain is on the snorkel intake side.
What is an alarming amount? I drain 100 ml every thousand kays.....
Major issue with oil blowby is amount of oil in the sump. Put it to max (8.2 L) and it will breathe it (OIL) like mad.
If you have your car serviced by someone else chances are they're overfilling the engine with oil because the way the oil drains down after engine was running.
Less is more in this case, I keep the level only 3/4 to 1/2 on the stick. That makes it about 7.5 L of oil.
Keep it to the max or over and it will be just spat out of the breather.
Cheers

Thanks Rumcajs. When I rub my finger onto that oil stain it's actually wet like it leaves a smudge of oil on my finger. I didn't know this happens a bit as you have mentioned?
How much oil is in catch can? I don't/won't know until I plumb the catch can back in again. Since it all leaked out that day at Tallarook.
It had a tiny bit of oil as well as the film of oil around it before we set out into the mountains as I done my oils inspection prior. So why it had that much after the day is unusual.

Definitely, doing its job. But mine seemed excessive, it's hard to judge how much ended up on the suspension below, but it seemed like a fair bit.
Air filter was last changed about 10 months ago.

The stain on the air filter is normal, as per post above it's on the intake side.

The problem with heater hoses is that they're not oil resistant, coolant maybe and they swell up.
