914 Cold Start Valve replacement P/N

tsuter · 03-10-2003, 12:44 PM

Help! Where do I get a CSV for a 1973 914 1.7L.
The CSV p/n was 0 280 170 018 or 0 280 170 017
These don't seem to be available anymore anywhere.
But something must have replaced it.
Mine leaks badly.
Thanks,
Thad

Have you tried calling?? Unless the part is specifically listed on the website as NLA (and sometimes, even if it is!) there is a half-decent chance that Pelican can get it for you.

Another possible option is to bypass it--run the fuel hose past it, instead of through it--and not bother with it. You can cycle the fuel pump once or twice, then stomp the throttle to the floor with the key on, then crank the starter. That will get extra fuel into the manifolds which is what the CSV does.

If you just drive in the summer, you probably don't even need to do that! Just bypass it and live without it. Remember, it only operates below about 40 F, and then only when the starter is cranking.

Unfortunately they were not much help except to say that 017 was discontinued. Didn't even have a picture of the 2.0L one. 0 280 170 015
What I need is one or two fuel connections (not banjo bolt) and a short pintel.
So it does not have to be the exact part.
Pictures anyone?
CSV is for special application purposes so functional equivalency is what is required.

Ah, I get it. The 2.0 CSV has a single fuel connection--a barbed plastic fitting-- and a longish nose. Not sure about the pintle itself (if I am correct about that meaning the little "needle" in the middle). The nose goes through the plastic spacer that also has the connection to the AAR, which I think is why it is longish.

Short nose is what I mean. Pintel probably not the right word. One barbed fuel connection is fine. Are their any pictures of a 2.0 so I can see how long the nose is? The CSV for the 1.7 was about 1/8' inch long.

maybe you could try a 1.8 CSV. it is an "inline" item unlike the 2.0 which is at the "end of the line".

tsuter · 03-11-2003, 06:55 AM

The number of fuel connections doesn't matter for me - only the lenght of the "nose". Shorter is best. And a single/multi barb connection(s). No banjo bolt.
Still need pictures of a 914 2.0 or 1.8 CSV that are still available with the bosch P/N.
Thanks,
Thad

since the "nose" basically sticks into the air distributor, i would not think the length matters. it just sprays extra fuel for a couple of seconds when the temp is below a certain value.

i'm trying to post a pic i found

tsuter · 03-11-2003, 07:26 AM

Here is a picture of my application. The CSV "nose" should be as short as possible. Like the 914 1.7 that I used for quite a while. One or two fuel fittings is fine. One preferred.
The P/N pictured is 0 280 170 010 for a 82 Volvo and they seem to fail on me faster than the 0 280 170 018/017 for the 914 that is discontinued.

Preferred application is 70-73 914 short "nose' CSV.

What is the P/N for the one you pictured?

jamcleod · jamcleod's Garage

BOS-0-280-170-026

for an 80-83 air cooled vanagon

why does the length make a difference?

tsuter · 03-11-2003, 08:02 AM

It's probably more theoretical than practical but I don't like the nose blocking air flow in that pipe and I "think" I get better dispersion with the shorter nose.
Anyway it looks like the long is all thats available now.
What is your source of the pictures and numbers - does it have flow rates?
Thanks,
Thad

If you're concerned about the length of the nose, you could always make a spacer. That's what the 2.0 has--the CSV pokes through the spacer into the manifold. In the case of the 2.0, the spacer also has the inlet for air from the AAR.

Picture of this CSV?
Cold Start Valve, 914 1973-76 2.0L BOS 0-280-170-015

Just about identical to the pic Jmacleod posted.

tsuter · 03-11-2003, 11:34 AM

"Just about"? Which has the lower fuel flow rating?
0 280 170 026 or
0 280 170 015
If 015 is for the 2.0L what is the motor in the 74-83 Vanagon?
I'm not trying to be difficult here but I need a CSV that is functionally equivalent to the 70-73 914 1.7L
I.e., same flow at 3.5 bar.

jamcleod · jamcleod's Garage

80-83 air cooled vanagon is a 2.0 Liter L-jet type IV

virtually same L-jet as on 1.8L 914's

i have never seen specs on a CSV, not to say its not out there of course, but i bet it's more trouble than its worth to worry about.

Dave at Pelican Parts · Dave at Pelican Parts's Garage

I don't know any of the specs on the flow rates. You asked about a pic, and the 2.0 CSV is almost identical to the one in Jamcleod's picture. The visible difference is that the hose barb is below the electrical connection, not beside it.
