Oil catch tank - vapours

[Gandi699]

Ive got an oil catch tank fitted and its similar to this:

Ive got a breather filter on the one inlet pipe and the feed from the cam cover on the other. I noticed today Im getting oily/petrolly vapours being emitted from the filter. Any one elses catch tank do this? Im assuming its because the vapour feed and filter are so close, its taking the easiest route out instead of condensing properly back into oil

Should be a pipe going from one inlet into the bottom of the tank and the other with no pipe on as the vent to atmosphere. Also the tank should / can be filled with some type of gauze normally a stainless steel wire wool or something for the the vapours to condense on.

My guess is that both of your inlets have no pipe on them and nothing inside for the vapours to condense?

Mine smokes from time to time.. Fucking stinks too with bonnet open :S

Personally, I would junk the filter and run a bit of pipe down towards the floor instead.

Just noticed it tonight, thought it was oil that had drilled on the manifold burning off as I saw it in the head lights. It was only a £20 catch can so I can probably say its empty and has no gauss in but I'll have a look inside it on the weekend

Oil on the roads + track = great.

Make sure the input / outputs are large enough, they can restrict the engine breathing and actualy make it breathe heavier due to the pressure build up in the catch tank

That. Most don't have anything for the vapours to condense onto.

How large would you say?

[Bedford126]

Both should match the factory rocker cover breather size.

[Gandi699]

Ok well these ones aren't far off as its a bit different to the catch tank I pictured

[Bedford126]

just make a feed pipe to the bottom from one of the inlets then mate and try to feed some stainless mesh or the washing up scourer's such as -

These are good because they don't rust and have a huge surface area for the vapor to condensate.

Cheers mate, oddly enough I found a new packet of those scourer things under the sink that I didnt know I had. Going to open it up tonight and have a butchers

I've not had any trouble running that setup - the pipe pointing towards the floor has been clean and free from oil for ~10k miles. Suppose it could be different for older/ heavy breathing engines though.

[Gandi699]

Ive just to see any oil in the pipes/tank to be honest, mostly its just condensation!

[Gandi699]

Opened it up to find no gauze and no extended pipe! modded it now and waiting for the sealant to dry :)
