I've been planning an oilcatch tank for a while, but the horrible prices charged by Greddy, AEM etc. set me off. I therefore decided to make my own.

An aluminium drink water bottle and plumbing from the local hardware store, total cost £17. Probably even cheaper in the Uk
The "air filter" (a sponge) is a temporary solution until I can find a suitable airfilter.

 

Looks excellent! I'd pay £20 for one! Where did you get the hosing from and how did you know the dimensions?

Good job! Always a pleasure to see people innovating!

hello!

excuse my stupidity, but what does this do? i guess it catches oil... but why?!

chris

 

I think its meant to reduce build up of oil in the air intake?? or some place.
Btw, have you got any pics of where the pipes run to/how there connected to the engine?

Thanks

The breathers run back from the rocker boxes/engine crank case and vent into the intake hose so your lovely high octane fuel is shafted by ****ty oil vapours etc:,I have tee'd the rocker pipework together and vented off to atmos through a small breather and also the crankcase hose or you could use an oil catch can.

 

I have a catch can also, though only have two outputs on it...what is the purpose of the 3rd, which has a filter attached?

breather vent

 

isnt there some down sides to this if you use your car every day?

 

Such as ? and Why ?

 

Haha, I did a similar rig with an empty tin of paint stripper, I flipped it over, punched holes and soldered in bits of 1/2" curtain rod for the hoses to go on. Cleaned up and painted in textured black bomb spray, then put on the little filter and clear hoses.

 

its a question m8.

 

Condensation can build up in the rocker covers Etc & give you a Gooey mess in your Oil filler tube, Due to the Gases not re-circulating around the warm engine, especially when venting to atmosphere. More apparent in winter
