I have been looking for a nice classic 635. I think the early 635's and 3.0SCi are the prettiest cars BMW has ever made. I found mine on e-bay (my first e-bay car purchase). I fell in love with it and probable paid too much for it but I do not think about that too much. I will post a photo of it when the weather stops raining and snowing. Now that I have been driving it a few months I have a few things I want to fix/change. I do not think this was a daily driver an I do not think this car was made to just sit in the garage. I want to drive it and take it to some club track days. The first few problems I want to fix are: 1 - Fuel leak when I fill it up: When I fill it up and park it for awhile I get a puddle of fuel under the center of the trunk. After I drive it about 1/4 tank the leak stops. I have replaced the fuel level sensor (it was broken) and the o-ring and it did not fix the problem. Are there any other penetrations in the fuel tank to check? 2 - Hood does not latch: The shaft the latch handle is mounted to looks bent and the handle slides off. Can it be straighten or replaced? 3 - Radiator nipple broken (short) on top return hose: Can the plastic radiator ends be replaced? If not, where is a good place to get a radiator? 4 - Intermittent instruments: How do you remove the instrument cluster? I want to clean up and tighten all the connections to the cluster and reflow the solder on the circuit board. I had to do this on one if my 318's to fix these types of problems. 5 - Change service interval computer batteries: Does this car have batteries on the SI board, like the 318i? If so, where can I get replacements? 6 - On-board Computer set-up: This too is intermittent so I want to clean up the connections here too. How does this computer work? How do you set it up? The owners manual I have is from a post 83 and the computer is different so the manual is no use. Does anyone have a manual for it or know where I can get one? Any help any of you can offer would be much appreciated. I look forward to meeting some of you at a club event somewhere. Thanks.
