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! |

How is your PCv valve.
If I recall correctly, the oil pressure in that location should not b that high. So.....maybe look at the case pressure and venting system. |

I tested the PCV valve during rebuild with the very scientific "suck test." It seemed to be in order...may be worth replacing if I can find a new one. |
