i got a 79 two years ago, im almost certain the problem with it is with the fuel, it runs very rich, i once had gas in the oil, ive went through and changed many things on the car like the fuel pump, filter, and distributer, but i still have the same problem too much fuel. the exost comes out black and the spark plugs are wet when the engine dies. the car isnt able to start many times and when it is running it cant go much faster than 15 or 20 mph. any ideas? _________________ 1979 924 parting ways

Colin,
That is the same symptoms I had on my 928 euro. Turns out the internal o rings in the fuel distibutor were toast/broken/cracked. This allowed system pressure (5+ bar) rather than the normal 3 bar to go to the injectors. Vaughns writeup refers to them as 4 oval shaped o rings. I was able to find some at the local autoparts store. Make sure you get the fuel resistant type.

Cool DIY, im doit for two dizzys, now they are well clean but now seeking for orings, I found a set of vinton brown fuel orings at harbor tool for 20 bucks, one question, the orings that go around the cylinder on the lower head, are those originally round or square, I like to replace them but not take them out yet, I found that sumerging the cylinder in chemtool, or similiar name made them expand and after hours they came too a thinner size it seems.
If it works Ill put the rebuild unit in my running car and test it. _________________ 1979 924 N/A, Snail Shell

It may be that your whole purpose in life is simply to serve as a warning to others.

This should be moved to the How-To section (so it doesn't get buried in General Discussions). _________________ erstwhile owner of just about every 924 variant ever made |

We should also add a poll to keep tabs on people's success rate. . .reputedly very low for this job. _________________ Toofah King Bad

Yeah, I've been reading the threads, and it seems like the success rate is one in three attempts before everything works. I noted in the 928 doc linked above that they actually recommend a specific sealant, Permatex Indian Head Shellac; Sealing seems to be one of the main issues reported. _________________ erstwhile owner of just about every 924 variant ever made |

Moved as suggested... probably posted it before we had a How-To section. _________________ Vaughan Scott
