I have a canister type engine breather which wont fit onto the engine due to the brake servo in the way.. i have looked everywhere for a housing that will attach to the transfer case but will allow me to fit a vent to air filter (K&N type) but cant find any, anywhere... considered cutting the oil separator of the unit i have but the OD is 31mm and 25mm is the biggest i can find

Errm, is there a question or a request to go with this or are you just keeping us all up to date with what you've been up to?

[ethana]

bit of both really i have looked pretty much everywhere to find a set up similar to the one fitted on the vizard book

There is an oil separator that fits under the servo, but you'll only find one 2nd hand now. I'm also a bit lost as to what you want to do but I'm sure a bit of creativity with domestic plumbing fittings and/or PCV filters off other makes of car will get you there.

okay i probably havent explained myself too well. I have a transfer case which is designed to house a breather, except when i acquirred the car it had a blanking plate in place instead. it was a rather ugly looking homemade plate which was never going back on. I know A series engines do well when they can breathe better , too much crankcase pressure causes oil leaks and better airflow helps engines in other areas. so rather than just slap a cover over the opening i was more inclined to make use... I dont really want to filter the air back to the carb (although timing cover end is running back the the carb) instead i wanted to vent to air through a K&N type set up. I have noticed on the cover of Vizards book there is a similar arrangement on that engine

You need this: http://www.minispare....aspx?pid=41641

Or you could cut and reweld the short pipe under the main canister at a different angle?

that is also a good idea. I must be getting lazy and old because i just opt for the easy option but i think the brazing rods are coming out and you have just won the idea of the month award

If you're that worried about letting the crankcase breath it should be back into the carb, not to atmosphere.

[Dan]

If you have one end of the pcv system connected up properly to the carb and the other end venting to atmosphere like this you will destroy the fuelling and the accuracy of the metering system in the carb. Either all the usual ports must be connected to the carb and the crankcase breathing throug the oil cap as it's meant to or it should all be disconnected completely and breathing to atmosphere with the carb inlet sealed. Connecting it up properly is by far the better option for a road car.

Ooopsy! I've only got one of mine connected to the carb and my fueling is all screwed up. I'll fix it and let you know if anything changes.

I guess I am a little confused about the venting. I have a vent on the top of my rocker cover which flows back to my air filter. But I also have a vent on top of my crankcase with nothing attached. Actually, there aren't even mounting holes on the outer portion (there is an oval similar size to my timing cover but no holes on each side, just one in the center) to fit those listed by seven ent and mini spares. It does appear that the vent itself has been tapped and could fit a different style vent or pipe. I have a good deal of oil misting out of this hole. Do I have a bigger problem or should I purchase one of these canisters and the filter assemblies, drill and tap mounting holes and be done?

If this tapped hole is a common type, does anyone know what type of thread and or size, or if there would be issues if I were to just plug it with a bolt since I have a vent off the rocker cover?
