Some of you asked about the S1 pictured here. It's been on the back burner for a while, but I started working on getting it running this week.
I picked it up last year from a guy who had installed a 16V engine from an '86, but was in way over his head electrically. I spent about a month rewiring the front of the car and sourcing correct boxes and sensors before I put it on the back burner to finish the RS. It hasn't been in service for over 10 years. I had to replace the gas tank, but it will now start and idle (roughly). I know the CIS-E system, but it's been a while. I did a differential pressure test on the distributor and got a control pressure that was HIGHER than system pressure. Logically, this shouldn't be possible. Any CIS-E gurus here? Attached image(s) |

I have a bunch of mrk1 stuff in the shop but the cis is out of a 8v motor....If the tank is rusty you are looking at big problems with the distributor as the filter may not take all the particulates out, or the plunger on the distributor may stick from rusting, depending on the moisture content of the fuel. I was ready to split the tank and get it re-coated and redo the fuel system before i decided to split with that rocco and got a second generation 16v.

Explain the test please. Could it be the accumulator? BTW, I've seen that car... (IMG:http://www.914world.com/bbs2/html/emoticons/wub.gif)

Test measures the differential pressure between the upper and lower chambers of the fuel distributor. You can perform the same test on your engine, but your control (differential) pressure is controlled mechanically where CIS-E cars have electronic control. Differential pressure should be 3 to 7psi LOWER than system pressure. I'm thinking this fuel distributor has simply been out of service for way too long. |

Need a better idea of which CIS-E system you're working with. Does it have a frequency valve or a differential pressure regulator? Do you have the gauge hooked up with the valve on the correct side of the loop?

Check your hose routings. I had all sorts of problems with a 924 until I discovered the cold start injector and regulator hoses were reversed. The hoses were bundled together so I figured they were properly hooked up. After modifying the warm up regulator and seeing no change in pressure I figured it out.

Differential pressure regulator. The valve is on the correct side. For this test, the pressure gauge is connected to the bottom chamber and you disconnect the DPR and note the pressure drop (but in this case, it actually rises 4psi). |

I should have known better than to assume the last guy didn't get his hands in the ignition timing. My timing light broke a few months ago, so I hadn't done any checking.
This morning, I loosened the distributor and started screwing around. It's still coughing after ten years of sleep, but it's getting close. It idles almost normally and revs in an almost drivable manner. There are a number of things to complete before I can run it down the street, but I'm now expecting the Roc to exit the back yard for normal service within a few weeks. |

Glad to see you moving forward on the Roc, share s'mo pictures when you get a chance! I had a 16v sciricco, which was my first new car - I loved it. Can't help with the CIS-E, my car was new and never had any problems while I owned it.

Things are going pretty well today. The thing about this S1 is that it's been converted to a 16V S2 engine.
The PO was in way over his head and I'm trying to sort out his mess without being able to see either the car or the engine in their original configurations. Today, I would REALLY love to see some detailed pictures of a 16V cooling system in its normal home. |

Go to vwvortex.com Hit the rocco section of the forums. My buddy has a 16v gen 2 that he's been slowly working on and always gets good advice there.
They have photos schematics the whole nine yards! |

A big moment in the life of any car that hasn't moved under it's own power in ten years.
I drove the car 15 feet! It doesn't have a drop of water in it, so I'm not running it for more than about 45 seconds at a time. Attached image(s) |

Good advice. I put a post up and was already greeted by a guy who saw this thread earlier today. Nice. |

Not too much love at the VW Vortex site. It's huge, but it seems like there's a lot of fighting and a bunch of youngin's who think they know it all.
I've found pictures of quite a few S1s w/16V PL engines, but nobody really wants to help. That's OK, it's not like I can't figure it out. Do you know that they have to upload pictures to a private web space and link to the picture's address to post pics in a thread? I thought that was crazy. They didn't seem to like that I thought that was crazy. Makin' friends........ (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif) |

Here's a pix of my 80 S that I bought new in 1980. $14,750. Traded in my 74 911S and never looked back.
That 80 Sciricco S was the best driving German car I ever owned. White with early ground effect, black strip with red highlight. Recarro (sic) seats were burnt orange and fit like a glove. http://members.rennlist.com/mikecool/scirr.jpg Good to see you got one. Mike Cooley Memphis |
