Anyone made their own catch can ???...for their diesel to stop the oil in the CCV oil vapour mixing with the exhaust gases...clogging the EGR

For example :

My DIY Oil Catch Tank for 115 TDI (under a tenner) - uk-mkivs

And if you have did it collect much oil...

thx...

I must say that's very posh

My DIY effort was a 500ml Dr Pepper bottle (had to be Dr Pepper for maximum performance), a length of pipe with a T-piece and breather filter.

Probably cost around £2 without the filter but looked slightly less professional than your effort lol

Neat little job.

I must say i would prefer somthing like semota racing alloy tank at about £40 as they look good and will last a liftime but still a great wee job anyway

well done

I'd expect any effect to be long-term positive, because engine oil burns very sootily compared with fuel oil or petrol.

That said, it's effect is one of less deterioration rather than a power boost.

I never made the one in the link...lol.;

I just wondered if other peeps had made one or bought one and it catched much oil...???

interesting use of a compressor water filter as an inline catch tank - remove its little filter and it gets out the oil and the vapours are re-burnt..

Please help me here, as I'm in my usual confused state.

The purpose of the CCV is as a pressure release valve for the engine to avoid a build up of negative pressure in the engine.

When the CCV vents it takes with it lubrication oil, soot, possibly unburned fuel, gases from the ignition process, water vapour and other stuff.

The standard CCV shoves all this stuff back into the air-intake pipe to be recompressed by the turbo and fed back into the engine in order to burn as much of the s***e as possible and thereby clean up the exhaust emissions.

The difficulty that arises is when some of the recirculated stuff contains lubrication oil which doesn't burn too well, thereby producing soot (particulate emissions).

The catch-can somehow traps oil (precipitation?) and removes it from the recycling loop, reducing the soot content of the exhaust and preventing the oil fouling the turbo and other bits of kit downstream of the air-intake.

Am I right (ish) so far?

If I am right, would a fuel-filter (canister and element) plumbed in as per the excellent the DIY Oil Catch Tank example above work better?

Would siting the catch can in a cold air flow (e.g. in front of the radiator) improve the catching ability?

I think a fuel filter would clog far too quickly.

The main reason people add a ccv catch tank is the oil enters the boost pipework, and normally collects in the lower pipes and intercooler.

A lot of the guys on the Honda Revolutions forum run catch tanks for track days.

It is amazing how much they collect at times!

Of course the totally non-environmentally-friendly way is just to run a hose from the top of the cam cover to down below the engine, and plug up the intake manifold connector.

This hose actually has a name according to a US diesel truckers site- but can't remember for the life of me....

Totally illegal for trackdays as well as you mustnt be dripping fluids onto the track, lol

Wonder if they still sell the charcoal filled crankcase ventilation filters for A-series engines? that would be a cheap in-line filter system...

No idea. I'd try looking at sites like Mini Sport or Mini Spares to see, but I don't know what I'm looking for.

Bit of a problem for anyone following on a motorbike too I'd imagine!!

It'd be more of a vapour with the occasional drop or two - as an ex-biker (still have the jacket!) I agree. Not to be messed with....

Of course the time I just missed a whole sofa set sitting in the middle of the motorway at night in Saudi Arabia was much more hazardous than a drop of oil on the black......
