I have a ignition wire harness that seems to have been chewed by squirrels (see photos). It seems to go all the way to the main fuse/control box but all the harnesses I can find seem to imply there is a connector somewhere along the way but I cannot find it. Can someone tell from the photos what I need to repair this? I thought about splicing it but there are connectors that are cut off right at the end. TIA.

After a bit more observation, I now doubt it is the pan. It seems like it only leaks after the engine has been running. That implies the leak is occurring where and when there is oil pressure. Since there is no pressure in the pan, that means it would be around the previously mentioned blocker plate where I assume there is pressure.

Ah, thanks. I could not tell from my cursory look that it was part of the oil pan. Hopefully it is not the pan gasket. It does not look like an easy thing to replace.

My 2000 GMC Sierra 1500 (4.8L V-8) has developed an oil leak somewhere above the oil filter (not the filter itself). I cannot see any leak around the valve cover (both gaskets were replaced recently) nor around the head gasket. I have not been able to examine it from below very well yet but I'm wondering if the filter housing is a separate part attached to the block and uses a gasket rather than being machined into the block itself. If not a separate part where the gasket can fail I have no clue where the leak could be coming from. Can someone confirm my theory or suggest where in that area a leak might originate? TIA.
