Engine CSV fire, even after everything is done right

[obieoberstar]

I would have surely thought there was an o-ring in there.

The one I had was a little loose. Glad I went with carbs with hard lines in the engine compartment.

Water-cooled Vanagon owners seem to be replacing the plastic fuel rails with some nice machined aluminum ones.

Really glad this topic is getting some attention. As important as fuel lines.

The system is as good as its weakest link.

I was looking at other CSV's and from what I've seen they don't have two nipples..just one..would still require a T somewhere??

There was a BMW series that also had problems with the rubber fuel hose leading to the CSV underneath the intake manifold so we're not the only cars with this type of issue...interesting stuff...

I wonder how many of these fires were with "original" wire harnesses...that's what almost did my Beetle in....

Wow thanks! That was educational!

Edit: So now the question is, can we loosen the crimps and disassemble/service this thing, then reassemble?

you'll never get it right....

the taper in the case is done AFTER the winding is installed. I had to pry the case open to get it past the rolled edge.

I worked fairly carefully pulling it apart. I don't see a way to slide it out and not destroy the case.

if you try to take it apart/repair/rebuild etc it's at your own risk....I sure the hell wouldn't do it.

I still stand by my theory the o ring gives up, the case gets filled with fuel and sprays all over the distributor

I do not see a sane way to service these units. let alone any hair line cracks in the plastic....

guys, give it up....it's 30 year old FI stuff that's NLA. time to move on here....or just look at it and make engine noises while you polish the trim

My apples & oranges testing begins: fired up a cold Golf, Bosch CIS Digifant I
with CSV valve un-plugged, fired right up, but the revs rise and fall quite
a bit more with it disconnected, idle 900rpm, deflecting to 450 or so with light
throttle application then bouncing back to 900. Maybe these were installed not just for true cold starts, but to prevent stalls when part cold as well?
This 1.8 will dip to 800 rpm after throttle blip when the CSV is plugged in, so I assume it's helping smooth out cold gear shifts too.
Is stall prevention worth lighting your precious bus on fire?

I guess if someone was not comfortable using a blocking plate. They could buy a rebuilt one from Bus Depot. I wonder how they rebuild them
