Hey guys,

I have noticed a large amount of oil on the underside of my rig, and need some guidance on things I should look into.

My valve covers are leaking (have been since I bought the truck a month ago) so these are first on my list. Parts are on order and waiting delivery.

But I am concerned about the amount of oil here. After the VCG job, I will clean and monitor, but I wanted to get a headstart in possible further diagnosis in case that is not the cause. I noticed oil on the bottom of my skid, dripping onto the oil pan, and traveling all the way back the side of the block. In my experience, valve cover leaks are slow and small, not this amount of wetness. Is it possible that this could all be from the VCG?

I am slightly concerned so have parked the truck for now.

On my list is the oil cooler o-rings, and also the rear main seal. I am really hoping it is not the rear main!

I have taken some photos:

anyways, long-time lurker here so happy to be a part of this forum!
