oily condensation in passenger side distributor cap only
is there an Ignition Distributor Rotor Adapter Seal [the rotor adapter goes through the base of a fiberglass cup and attaches to the camshaft via a 5mm Allen bolt] for Mercedes 500SL 119.960 engine ?
I've found a lot of oily condensation in only one of the two distributor caps. And there was some rust deposit on the rotor adapter where it passes through a fairly tight hole [behind the fiberglass cup that mates up with the distributor cap] that looks like it might be a seal before attaching to the camshaft. The classic benz mechanic at a reputable local benz dealer says that there is no seal -- that the distributors on the 500SL are known for collecting a lot of condensation because it is poorly designed -- but there are vent slits on the bottom of the newer distributor caps that I just replaced 4 years ago, so how can that be, and why is only the passenger side wet and the driver side is bone dry ? I am also having heat-soak, no run, no spark issues after the 500SL engine compartment gets hot -- within 5 to 10 miles, the engine bogs down, looses power, and quits running when the engine slows down to idle speed, and then wont restart, but might make popping sounds [through the intake?] while laying on the starter, and pumpping the gas pedal trying to start it, until the battery wont turn the engine over -- its a new battery - had to have it flat bedded home. started up and ran fine the next day. runs great cold, then dies when it gets hot. But now there is no spark -- have even changed out the crank sensor, cam sensor, over-voltage protection relay and almost all ignition parts except for coils and the EZL ICM /ign control module. fuel distributor was rebuilt 4 years ago, which fixed the heat soak wont run when it gets hot problem back then -- it ran great for 22 years, according to the previous owner. -- could a rebuilt fuel distributor's o-rings fail in 4 years time when the originals lasted 22 years ?? fuel pressure is good, through out. I was trying to fix the heat-soak/hot-stall problem for 6 months now, and now I have an ignition problem to fix before getting back to the hot-stall problem. Sheesh. any experience MB guys out there with possible answers would be greatly appreciated. |

Google -> mercedes condensation under distributor cap
Lots of hits. In one of them, there's some talk about using a Ford boot to solve the problem. I would post the link, but the people who run this forum do not allow posting other URLs in the threads here. Not saying it will fix your problem, but at least one seemed happy with the mod.
