DIY ~ Oil Catch Tank

[hakim5857]

Just want to share, this what i do with my crankcase breather which usually the hose connect to airbox... I dont like any engine oil get inside the airbox and suck by the carb. In the long run, the blow by/vaporise oil from crankcase will accumulate inside the airbox and will drip everywhere. Not good for enviroment

I found out the Zippo refill tin can perfectly fit and i used stainless steel mesh breather under the petrol tank.

Okay possibly a good idea. Did ya do anything with the air box drain hose. Reason for asking just pulled my carbs and the air box had not only oil a small amount, but also trash stuck to the oil. Am wondering if it came from the drain or at one time it had bad boots. Probably both.

Was sitting on throne and thinking is your breather hooked to bottom of air box? Good idea getting better.

. My bike is 32 years old and I have never found any oil residue (nor trash) that amounted more then getting a couple a q tips dirty. The new tubes for the air box now have a removable plug in them, it seals the air box and you can remove the plug if you need to drain the airbox (if one has to do that, you've way too much blow by from the pistons or something). I guess at some point some really bad maintained bikes were dumping enough oil and getting on the rear tire. Guess I don't need to say what can happen then lol.

Is your Zippo can vented? If not, there won't be any airflow to get any vapors into the can to collect any fluid.

he has a small k&n style filter tee'd into the hose. you can see it poking out the top of the frame

OK, did not see that before.

Apparently, any vapors are going to go out the filter, any liquid that has condensed in the line will drip down to the Zippo can.

Personally, I have not had any problems with the vent line connected to the airbox, but not everybody has an airbox.

Hi all,

Just my humble opinion;
The carb suck air from the airbox case, before get into the carb it went through the air filter. But our GS air box got three hole connected with; 1 for crankcase breather, 1 for drain any petrol overflow or engine oil from crankcase & 1 of course for our airbox case with filter. So better i shut the crankcase breather as engine oil may vaporize & get inside the airbox as sometime bad thing may happen more likely to our 30++yrs GS. With that, we may extend the carb & airbox cleaning service. With oil catch tank (OCT) also we will know that our engine got problem when the OCT fill up with engine oil within a week .

I want my carb to get clean fresh air from the filter blend with petrol but not with engine (vaporize) oil to get clean burn. For the drain hole under the air box i may put stainless steel mesh filter. i dont want to shut that drain hole as If my neddle valve spring faulty the airbox will floaded with petrol.

After 6 months installed the oil catch tank (OCT) ~ the result;

If this end up inside my air box, this mean that i need to do air box cleaning after 6 months ++ and carb cleaning after 1 year ++.

What's the red electrical box to the left of your Zippo can in the first pic?

I am guessing fuse box.
