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! |

It's prime driving season, so it is painful to have the car down for more than a day or two. (IMG:style_emoticons/default/evilgrin.gif)
Took a look at everything with fresh eyes last night and think I found a few problems. My upper fiber washer was originally installed above the steel ones. According to the PET posted by Puebloswatcop the fiber washer (at least the lower one) should ride against the distributor housing. I moved the top one down, below the top two washers so it will ride on the housing. I installed the set of trigger points with the "guards" on them. Additionally, my felt tab that rides against the distributor shaft was shot. It was sideways in the disty when I pulled it apart. Picked up a self-adhesive furniture felt kit, pop-rivets and washers at Home Depot to rebuild the felt tab. I had to trim a little off the washer for clearance, but I think it will do the trick. I'm still running a cracked, but intact fiber washer until I get the parts, but I think this may help. Thanks 914world! (IMG:style_emoticons/default/beerchug.gif) |
