I wanted to refurbish and waterproof the wire harness entering the back engine cover while I have the engine out. The rubber plug has softened over the years and is not in great shape. Anybody done this and what did you do to make it waterproof?

Is it the external grommet that enters the top of the case - or the internal grommet that slides into the groove in the casing?



Mine was the external grommet - it had turned to "GOO".



I re-wrapped all the electrical wiring and then used an oil resistant silicone sealer to fill the gap from the internal grommet to the external case - as previously said - give it a while to set (about 24hours) then everything should be good to go..

It is the external grommet and it has pretty well turned to "Goo" also. I bought some black Permatex yesterday and I have some spiral wire cover on hand. I will hopefully have some time to work on it today. Will post the results.
