924 FUEL DISTRIBUTOR QUESTIONS
Well, We finally gave up and took the 82/924 to a mechanic (recommended for his experience in K-Jetronic) to troubleshoot the chronic poor performance of the engine. This was after exhausting my expertise and going as far as I could with the multimeter and Haynes. He checked and set the pressures and adjusted the CO. He also disconnected the Lambda circuit so the car now runs full time in the "open loop" mode. Anyway, it still runs like crap and he has advised me to replace the fuel distributor. Before I drop the big bucks for a new fuel distributor I have a few questions that maybe you guys can help me with.
Are the fuel distributors prone to problems? I understand the older ones had cast iron and steel parts that were prone to corrosion and the new ones are aluminum with some plastic interior parts. I have another fuel distributor from an 80 (got a good deal on a parts car). Is it worth it to install it in the 82 or is that one likely junk too? Are there any other cars that share this part? Would it be possible to find one in the bone yard from a Volkswagon or other European car. Does anyone have a good source for an inexpensive new one? We have been going hard at this project since February and are getting close but just when things start looking good, something else fails. Last week the right cv joint started making noise and now the headlight mechanicals are getting fussy. But we'll keep going a least until my wife figures out how much money I've spent.... Sure is fun to drive...... Jon Aborn |

I'd give the other fuel distributor a try. Since this mechanic is good with CIS, he has probably checked the O ring in the pressure valve of the one you're running now.

Generally speaking "yes" you can exchange the
CIS fuel distributors found in VW Rabbits, Sciroccos & Golfs. Main thing is engine size and cleanliness. The piston in the center of the top piece must be bright, smooth, free of pits and scratches. There must be no air leaks after the flow sensor(whose circular plate must be precisely centered). The pressure regulator must work & provide a band of pressures(check service manual for your engine & year) Try the '80 unit, after inspection. G'luck. |

Did the presures check out.
Do the injector test yet? Did the pressurse all check out, if the mechanic checked them and diagnosed a bad fuel distrib, then it needs replacement, but if he is just guessing, then make sure he clarifies. |

The injectors have been checked and are all spraying in a nice pattern and atomizing well. I did not do any flow measurements.
The mechanic checked and adjusted the fuel pressure and set the CO for clean burn. He had a problem because every time he shut the engine off and restarted the CO required adjusting. He never got the thing to run decent and I drove it home running as rough as when I took it in. His advise to replace the fuel distributor was based only on the above things that were checked. Also, myn spare fuel distributor is junk, sat with stale gas for too long and all gummed up. Oh well, after everything that has happened this week, I feel fortunate to have these problems to solve...

Part Werks in Joliet Illinois has rebuilt fuel distributors for about $250.00.
They have been great at helping me trouble shoot as well. They have just about everything a porsche would need The number for them is 1-815-462-3000, Jay is the owner. |
