Post subject:  Engine breather - what's best?

Looking to make sure my engine breathes as well as poss, but I'm faced with choices.

Some new tech:
http://www.ecas2cvparts.co.uk/complete- ... -2226.html £95.

A new version of the tried and tested design:
http://www.ecas2cvparts.co.uk/engine-br ... -2018.html £65

A repair:
http://www.ecas2cvparts.co.uk/breather- ... -2085.html £42

Anyone have any experience of these parts? My inclination is to go for option 3 (recycle and re-use wherever possible) but I don't want to waste my cash if it's going to be no good.

Option 1 should be fine, except it's rusting faster than most 2CV's
Option 2 should work, but as with most modern replacement parts, some of them didn't even work from new.
Option 3, i don't have experience with this, it should work okay, but if the rubber is of the same quality as the other replacement rubbers, it will be over soon.

I've repaired a couple, it's dead simple. Use silicone baking sheets for the rubber. You can get them off amazon for a couple of quid and there's enough material to repair a couple of dozen.

Do the job perfectly and prevents dripping.

Fitted one of the second listed ones end of Sept and can recommend them:

Only two bolts and a couple of hoses, job done.

I've tried all 3 options.

The No 1 option is going well after 7 years, but is showing surface rust - performs fine though.

The No 2 option failed in less than one year, which led to...

No 3 option. I can recommend this, and will choose this again in the future. A bit fiddly to get done, but produces the best engine vacuum I've seen and cheap enough to buy just the rubber parts in a few years time.

In my Dyane the last owner put in a mil carton underneath the breather pipe and fills up pretty quickly.

Putting in one of these medications to the breather - would it stop this leakage ?

Ordered option 3, along with a gasket set and some valve stem seals, to go with the piston rings I bought a couple of months back. All set for engine rebuild in the coming weeks!
