Does anyone have a good diagram for how to properly plumb a catch can? I have tried a couple of methods and am not sure how to do it the best. You can't just cap of the rear and intake manifold ports for the PCV. You get a can full of crap and an engine that doesn't run at its best.

Thanks mates, DR

 

My 1962 Mini vented the crankcase from the tappet cover down towards the road, simple.

What year is your classic?

 

Like this?

 

Yup!

 

I have a Gen2 Mini S.

 

This is the classic Mini talk section.

 

.....

my first thought was 'catch can on a classic??????'

aren't they supposed to just drip on the ground?

a catch can would be a soup can held with a piece of wire under the end of the hose meant to send the drip under the car!!!!!

 

I do think he's talking about a MINI, not a Mini here.......but to the point a lot of people do run catch cans on classics too, mostly race cars tho......

 

BTW, that's a really early 1100 in my pic, besides the 2cc, what's the difference between an 1100 and a 1098?


I guess this could be a 1071, but I had one of those in my 62 Cooper S and the badge on it said 1071, not 1100.


I guess the only way to know for sure is to pull the head and measure the bore - the 1071 and 1098 had very different bore/stroke combinations.

 

What Are PCV Oil Catch Cans?

http://oilcatchcan.com/

read that then these comments apply ....

for me ... I have old school filters on my breathers on the 79 ... no PCV or any associated lines ....

race cars would want/need catch cans as oil being dispersed to the track (as might happen with my simple breathers) is a NO NO ..... same reason they run water versus anti-freeze for a coolant .... AF is slippery when spilled on the track ... water is a non-issue.

 

Apologies. I posted this in the wrong forum. DR
