I found a source for some NOS 2.0L cold start valve. They will be reasonably priced at around $120 shipped, not the $200+ prices on Ebay. I will take about a month to get them because of the location. Let me know if you want one. Going to order at the first of next week.

Mark, how do they differ from the 1.7 or 1.8L CSVs?

Please put me down for one Mark - if it is the proper part for my 73 2.0 - I'm not sure offhand if the 73 was the same as the 74 GA 2.0 nor as the GC 75-76 2.0s on the CSVs. May have been the same CSV 73-76 2.0's but I cannot check that right now, & didn't want to miss a spot in line again! Let me know when & how much you'll need for shipping by PM or email, whenever you need my $'s! Thanx! (IMG:style_emoticons/default/beerchug.gif) Tom /////// |

Unless you live in a location at or below freezing, the thermoswitch/TTS (temp driven ground for the CSV electrical circuit) will not activate and the CSV is never called into service to provide fuel. They become a problem when it leaks though (too rich) even in warm climates. Suggest that these are only needed by the cold climate folks and everyone else should just delete or disconnect them.
TS/TTS values (from Anders): 311 906 161 : -12 to -18 deg. C / 10 to 0 deg. F 311 906 161 A : 0 to -10 deg. C / 32 to 14 deg. F 311 906 161 B : -2 to -8 deg. C / 28 to 18 deg. F 311 906 161 C : -6 to -14 deg. C / 21 to 7 deg. F |

F 311 906 161 C : -6 to -14 deg. C / 21 to 7 deg. F Jeff, Thanx for the info, & it's generally true - but the caveat is that nobody then takes their 914 somewhere with cold enough temperatures for it to kick in, such as on higher mountain passes or Pike's Peak or something on a rally or group drive, etc. Some of our 914world drives up to Palomar Mountain, Big Bear, Lake Arrowhead, Mount Baldy, etc. can run into conditions for much of the year where the CSV would be needed & kick in to start the car. I'm sure other areas in the Southwest, Southeast, etc. probably also have higher elevations where it gets cold. And of course - you find the twisties on those mountains! (IMG:style_emoticons/default/driving-girl.gif) (IMG:style_emoticons/default/driving.gif) Over past years I have taken my 914 up to the local SoCal mountains, Mammoth, Tahoe all in CA, Ashland OR, Park City & Brianhead UT, CO/UT I-70, etc. - & may take my 914 to such cold condition areas again in the future once back on the road, & also prefer to keep my EFI complete & intact. So anyone who may use their 914 at some point in that way, should keep their CSV. |

Going to have to cancel out on this offer. When I contacted the seller they had 5 but they are all gone now. You have to move fast these days.

F 311 906 161 C : -6 to -14 deg. C / 21 to 7 deg. F Fully agree on this. In MD temps do get to freezing and below during 3 months out of the year. I have started my car below freezing temps and while it initially starts with a low idle it quickly raises to above 1500 RPMs as part of the normal startup of FI. As Jeff stated the less items that can cause problems in the FI the better. I believe another member on here as well as others have removed the CSV, decel Val, and there was one more. My car currently has a disabled CSV and no Decel Val. It starts and runs great without these. |
