Title: What size fititngs for oil breather hose and ends Post by: Lids on February 07, 2015, 23:19:45 pm As the title says. What size fittings should i use as a minimum. engine is 2332 Cr=10.5:1 Dry sump.
1/2" NPT or -16AN? Or bigger? Title: Re: What size fititngs for oil breather hose and ends Post by: Erlend / bug66 on February 07, 2015, 23:25:52 pm Depends on how much the engine breaths. I would guess a DS engine would breath less.
I would go as big as possible. Mine is 40mm ~ 1,5"... Title: Re: What size fititngs for oil breather hose and ends Post by: spoolin70 on February 07, 2015, 23:35:35 pm Lids - Are you referring to the breather hose from the oil tank to breather tank ?
I am going dry sump too (but only have pump and some fittings so far) Thanks Darren Title: Re: What size fititngs for oil breather hose and ends Post by: spoolin70 on February 07, 2015, 23:44:01 pm [attachment=1]
X2 AN-12 to the breather/catch tank. Title: Re: What size fititngs for oil breather hose and ends Post by: Lids on February 08, 2015, 05:09:20 am Actually referring to case venting to berg oil filler, but forgot about sump tank venting, so that as well

If you do a search here on The Lounge you will find plenty of threads where this is discussed (thats the beauty with forums) and you will also find how you can port the inside of the case. I have a 24mm hose on my little engine. -BB- Title: Re: What size fititngs for oil breather hose and ends Post by: spanners on February 08, 2015, 22:21:17 pm Personally I like to went where the "pressure" is created and not the valve covers.

There are just about valid reasons to vent the rocker covers for circuit racing, but with dry sump the best way is to scavenge them.

[/quote] can you explain scavenge them please? dry sump is new to me :-[ :) Title: Re: What size fititngs for oil breather hose and ends Post by: Andy Sykes on February 08, 2015, 23:53:14 pm have a scavenge part of the pump pull oil out of the rockers but you will need more than a 2 stage pump
Title: Re: What size fititngs for oil breather hose and ends Post by: Lids on February 09, 2015, 20:17:10 pm I am going to run dash 12 for all the hoses, it just now means the berg breather will need modifying and new bungs welded on.
