Now it is winter time the colder weather will mean the OCC will need emptying more often.

This is todays fill from the summer months.

That looks like something evil is living in it!

What is an occ? or is that a jar of honey?

I know , fancy a pint...

Oil Catch Can...

looks like honey but certainly don't smell like it.

Oily water stinks and is the remnants of what is circulating around your engine and breather system when you don't have a catch can fitted.

As the the condensation from the top of the engine starts to warm up and evaparate it leaves this muck floating around.

Cheers mate never to old to learn, and a good idea!

I suppose hot oil vapours hitting ice cold metal = loads of muck!

I really must get around to fitting one of these.

I cleaned the throttle body a few months back and it was fairly gunked up, can only blame the crud that's circulated around the intake.

I really can't justify such expense for a Saikou Michi OCC. I'm a draughtsman for an engineering firm and could knock them up for about £40 each. But it's getting the design right. I don't like that you can't actually open the Saikou unit to clean the insides, so would want something with a screwed top and O-ring seal. Small 3/8" BSP screwed socked on the bottom for a tiny isolation valve would be sufficient to rid the gunk.

Will need to ponder over this one.

Ponder, design, make and sell to the rest of us I just vent mine at the moment :p

I'd be interested in buying one

Well it wouldn't be difficult to adapt the Saikou can, but replace the mesh with a baffle plate and have some sort of bolted or screwed top.

I'll knock a few drawings together and see what our fabricators make of it. May be able to get away using some 100mm thin wall pipe with a welded bottom with a threaded plug in there, then whatever fixing method for the top.

I like the universal styles you can get on eBay, but they're only 15mm ports.

That's the advantage to having a see through CC!

Hear what you are saying there, and if you have the tools and know how go for it. These Saikou Michi OCC do have the drainage at the bottom on them to get rid of the gunk.

I removed and emptied my can yesterday too. Pretty impressive volume came out!! Seeing as it's only a 1/2 litre can.....

It obviously "catches" a huge amount of condensation that would normally just harmlessly pass through the system. As the catch can is aluminium and freezing cold at this time of year, it acts as an effective condenser! There's not actually that much oil in it. Well, less than I thought (I let that jug sit all day so the liquids separated).

If you've got a can, as Bowders has highlighted, you really need to check it once a month in the depth of winter. That's only 3-4 months worth for me above! It catches pretty much nothing over the summer.

I know it summer, but after 1.5 months... nothing, not a single drop in the OCC. To the point that I am wondering if I have tightened the nut properly. Also, anybody any tip on how to easily drain this. Access is a bit of a pig.
