I was just wondering if i installed an oil catch tank to my 1380 that it would be beneficial in the engines operation / performance etc.

I am currently using the normal K&N type breather filters from the crankcase and the timing chain cover but i have not got one on the rocker cover but, the oil filler cap has a tiny breather hole in the top as standard.

I have been reading Vizards bible and was interested with this topic.... scared me a little as it seems the engine needs to get rid of quite abit of pressure etc.

Any thoughts would be appreciated.

It will do nothing to the operation/function of the engine.

Thanks for the reply, what benefits do they give in general.

Catch tanks catch anything that comes out of the breathers.

That is what they do.

Connect the breathers to the carb. If you run a weber, connect them to the inlet manifold witha pcv valve in between.

On a roadcar it would be very stupid not to connect the breathers.

No it would not be.

It all depends.

If you want the engine eating the crap it's kicking back out. You want clear air for best power

You forget the pressure it creates and the dirt that get in. Do people even read vizard these days? On a roadcar its Bull.... To ruin an engine sooner. D

How do you know what I forgot?

Go rebuild your engine every 30k miles then.

And all this has nothing to do with oil catch tanks,

Yes connecting to the carb can reduce the pressure in the crank case. But then you are reducing the output of the engine by reducing the combustible parts of the fuelling charge.

Having brothers with a greater than standard bore or having more helps by kinda doing the same thing but without robbing power from the engine.

I prefer every 2k 😀👍
