I have a 99 GMC C6500 that's been sit ting out back for a while. I drug it up today to see if I could get it started. It has this tank down below the drivers door right next to the air drier.
I had assumed it was an air tank. Noticed it seems to be leaking a little oil so I investigated a bit. It has two hoses. One goes to the block where the engine oil pressure sender connects. The other goes to the oil pan. It's approximately 8" diameter and 12 or 14" long.
So is this some sort of external oil filter? Some sort of extra oil storage? If so, can I just eliminate it? One of the mounting clamps has rusted in two, and I doubt it will be long before it's spewing oil. It's a 3126 Cat engine. I have a 3116 in another truck that doesn't have one of these.
So, what is it and do I need it?
