I was visiting my family out of state and was chatting with my BIL about his car. Being a BITOG member, eventually OCI came up.
His trips are are never longer than 10 miles, and sometimes shorter than that. No expressway driving. In the winter, the engine may not get up to temperature for days. He was using bulk mineral oil, changed "about every 5K" at various quickie lube places. Total miles: 85K.
The car had a small weep from the back of the valve cover, so I offered to help by replacing it.
Pictures of what I found:
I'm going to have him do a couple of short changes with Rotella T6 to try to clean some of the gunk out of the engine. I'm not sure about the timing chain, it was a loose between the intake and exhaust cams. I'm not sure it is going to hold on for long.
