Question Oil in connectors?

pulled the valve cover on the passenger side to change the glow plugs when I noticed that the glow plugs were under a rocker. Wasn't sure how to get them out so I thought I would check this side of the engine for a problem I have been having with bad fuel mileage, no power, and somewhat of a miss.

I started by pulling the outer two connectors on the VC Gasket. The one up front near the glow plug relay was full of oil and the pin for the second glow plug was burnt. Does anyone know if I can replace the connector and pin? The Under Valve Cover Harness looked good except for all the oil in the Injector Connectors. I cleaned them out a little, but is that normal? Why would there be a rubber gasket around the connectors if oil was supposed to be in there? All four connectors had oil in them. The back Outer VC Gasket only had a trace amount of oil in it.

After I cleaned them, I started the engine and checked the oil coming out of the spouts. That looked okay I guess. Not sure how much oil should be coming out, but all looked about the same. Then I pulled each injector connector one by one to check for any problems. All checked out good.

That is where I am at. Haven't done the other side yet. Need to find out if I can get a connector for the Engine Wire Harness that goes to the VC Gasket then press on from there.

the valve cover gasket on that is a electrical component when the insulation starts to breakdown it becomes a mild conductor so you loose current (short). the connectors under the valve cover will have oil on them. if your engine surgis when your trying to go slow pull those injectors and change the o rings.

Changed the burnt connector and the two front UVC Hanesses. Got the glow plugs out and changed. Only one, not sure of the cylinder number but the one by the down pipe, was covered in carbon and a S.O.B to get out. It was also the only one of eight that was reading less than an Ohm when measuring, but I figured since I was in there I might as well change it. Well now I have a coolant leak to fix. There is coolant all over the front of the engine. It only leaks when it get up to temp. I think and hope it is just the hose from the thermostat to the radiator. That was where most of the fluid was and the belt is covered in coolant too. Another day and another dollar...

I didn't read all of this... but to get the GP's out you just have to pull the white wire and use a 10mm deep well 1/4" drive socket. No need to remove the rockers, but they aren't hard anyway.

Well, its not the hose. The water pump is leaking out the seep hole. Darn.

Has anyone ever changed the Rear Main Seal and the Front Main Seal on the engine? How hard is it to do, and what do I need tool wise? Thanks....
