Oil Catch Cans
aksman - 4/12/20 at 05:49 PM

I'm sold on the benefits of crankcase ventilation for an A Series 1275, but... I've done my research and I am still uncertain about which option to choose.

I'm not averse to buying new when required, but I prefer to buy used when feasible, so...

OPTION 1
I see plenty of cars using crankcase breather filters and no oil catch tank.
There is a view that oil can be flung onto the filters, blocking them and making the ventilation worse?

OPTION2
I see plenty of oil catch cans that appear to be an empty vessel with 2 or 3 pipes leading who knows where.
There is a view that this is bad practice as there needs to be a mesh filter at the top to contain the oily vapour down below, keeping it separate from the top which vents to atmosphere via a filter?
Also, it seems impossible to identify whether a used catch can has a mesh filter or not, apart from when it is known brand and model?

OPTION 3
Brand new oil catch can with mesh filter in the top?

Your opinions / experience / recommendations would be much appreciated
TIA

Mine was an empty Fosters can, that mainly consisted of white foamy water, taken from the rocker box, and PCV valve take off

A bike drink bottle and cage, simple fixing. Bit more expensive than an empty can though

You can buy bike drink cans in the pound shop, not sure how much they cost though

No problems with oily fumes from no filter?

Nice and Locost
No vent to atmosphere?
Or was it a closed system drained back into the sump?

The pipe goes into the bottle with a bit of foam sponge around the tube at the opening.

Sounds simple and effective. Cheers

So far no-one seems to see any benefit from using an aftermarket can
Which is good if I go down the Locost route because the money saved can be spent on something else
My primary concerns are letting the engine breathe and not putting oily fumes back into the inlet manifold or the engine bay.
The question is: "does an aftermarket can do anything that a Locost can can't?"

Exactly what I used. As a cyclist I already had bike water bottles and bike water bottle holders so it only cost me my time.

Metal Scrubie would work well as filter.
Mass of metal cools the air/oil mist and causes oil to drop.
As it will always be saturated in oil, even non stainless will work and last OK.
HTH.
