1974 D-Jet, 2056CC.
I pulled my disty apart two years ago to clean and grease it. Ever since then, about every 800-1000 miles, the engine starts to run poorly. The cause, oily trigger points. I pull the trigger points, replace them with a set pre-cleaned with denatured alcohol and drive problem free until it happens again. For quite a while, I thought I used too much grease on the top when lubing it and it was leaking down and fouling the trigger points. Now, I'm pretty sure the oil is coming up from the engine side and causing the problem. Disty to case seal is brand new. I just took the disty apart again. From top to bottom, there is a fiber ring then two steel washers. After the shaft passes through the disty, there is one fiber washer, then one steel washer before the drive pinion. Is this layout correct? Any other suggestions on the subject would be appreciated. Swapping trigger points and re-timing the engine every 1K miles is getting old. Thanks! |

Hello,
in our D-Jetronic-forum someone just has disassembled a Bosch D-Jetronic - distributor (Mercedes-type). He carefully casted out the sleeve bearing and found a shaft sealing ring beneath it. Most likely that is the same in your distributor. You will not get rid of the oil-problem without changing this sealing ring. The felt part is only for regreasing the d-jet-camshaft and the fibre blocks a little bit - not for taking off that oil. Here is the link towards the topic - sorry, German only: https://oldtimer.tips/en/forum2/ignition/43...n?start=20#4085 But you can communicate in Englsh there, too... Regards Norbert |
