Crankcase Breather

[Andi]

Hi all,

 

I used to have a heavy duty braided breather pipe hanging out of the engine which I was about to

put a catch tank on for.

It was there yesterday but after a blast in todays tempting weather, it appears to have dropped off.

All that is left is a rubber bung and there is slight spray underneath the bike carbs.

Where could I get one from and how is it fitted.

All I can see is a hole in the rubber with no clear way of attaching anything.

When I looked in the Haynes manual it seems that the pipe (albeit a different sort of pipe) is just pushed in.

 

Regards

Andi

The "pipe" you refer to is the negative pressure valve and is a push fit hence the rubber gromit. This was originally was attached to the inlet manifold, in your case it should have had it's valve removed and a pipe attached to the top and taken to a catch tank or brought up as high as poss and had a small filter attached

Cheers Chris.

I take it that I could buy one of these

and attach a pipe it would just push in?

It looks like a direct replacement and if so would be ideal. But I do wish people would put a rule alongside or even a coin so to judge size

Burtons used to do them and still do, top one on this page. Breather Pinto one can be used with throttle bodies, bike carbs or twin sidedraughts but you have to remove the valve in it if using without manifold vacuum.

Check you have clearance below your carbs if you go for the straight one...

Cheers Dan,

Ive probably got about 2" and as Chris said I wish they sold these things with a scale.

Anyway I ordered it off ebay this morning.

If that dont work ill try one of the Burton elbows.

 

Its the waiting game that gets on my tips.

 

Thanks for all the help.

Theyre all about 1 inch from top to bottom (where it fits in the crankcase) ie excluding the bit wot fits in the crankcase itself.

 

Guess who sells them for 1/2 the price of Burtons??????? Guess Who....

 

Ignore the write up....the website must be a bit scrambled at the mo'

I have the breather pipe land on the door mat today, it does seem a serious bore and will probably just fit into the rubber on the oil seperator (see attched borrowed pic from an old rhocar post)

Or does the whole of that cylinder/seperater have to come out?

There doesnt seem to be anything in the hole but it it does seem to go right into the crankcase, just down maybe an inch.

 

Thanks

The bit in the pic stays where it is. The breather elbow should be a firm push fit into the rubber in the top of whats shown. Then pipe to a catch tank, coke can is suitable.
