Was it a black liquid? May have been gas soaked carbon from the misfire.

Could just leave the cover off. Holds heat in anyways.

That sounds like gas soaked carbon and grime.

Ya no PVC valve. We have had several of the individual coils go bad on these LD8'* and cause the symptoms noted.

89056799 is old coil that doesn't fit the LD8

89017778 is what you want. Rock Auto is having a closeout on them for $98. 4 pack..... welcome to modular parts scheme'ing. At $98, itz a bargain. It shows as D593A in their online catalog.

YA, the Delco one. I say bargain because the off brand is over $200. I really doubt you will find a single coil. I have looked extensively for such an animal. No Luck. They are made/sold as a modular unit.
