I did some M&R on the Burban today. An oil change which was only notable by the fact that I have now 50k miles on the truck. How did that happen? Where did I go?

The other chores were to adjust the drivers side door. The top of the door seems to have opened up a bit which is causing wind noise next to my head. I marked the upper hinge before I loosened all the bolts one turn except the lowest one on the bottom hinge. That lowest bolt I only loosened about 1/3 of a turn. The idea is that I could bump the op of the door inward and not loose any other adjustments.

Fortunately it went as planned. I measured the top of the door frame to the cab with a micrometer before and after. I was surprised to see how much movement it took at the hinge (about 3/16") and I only gained 1/16" at the top of the door. (Photo #2) A test drive proved that 1/16 inch was enough to quiet the noise.

The other thing I did was to modify my PVC hose. As of late the truck seems to suddenly leaking a lot of oil. I noticed a bunch of oil in the rear main seal area when I did the oil change and there was oil leaking from the front of the intake manifold above the water pump. After further inspection I noticed the hose to the PVC looked like it was collapsed near the connection at the carburetor. I surmised that if the hose was collapsed then there was no vacuum then that might be causing higher pressures in the block that was causing oil to be forced out. Valid or not it was an easy fix. I bent and flared a piece of 3/8" tubing to make an 90 degree bend then installed it where the collapsed section was. (Photo #3) I took an hour and a half drive to Mollala and back and I wasn't able to see any oil leaking from the intake. (Photo #4) Yea! A win for now but, we'll see what city driving brings.
