Wound up with an engine oil leak from somewhere near the bellhousing. Cleaning it up and looking with a light I think it's the oil cooler/filter adapter on the drivers side of the engine. Ordered a seal kit for it. Also had a very minor weep from the transfer case rear driveshaft seal, so I ordered one of those too. Transmission spin-on filter is rusted so I also ordered a replacement (I then found the AC Delco filter I had already ordered and received earlier to replace it, so I guess I now have a spare that I'll stock?).
Since I had the truck on the lift and I'm waiting for parts, I decided to install the fuel pressure regulator I've had on the shelf for 6 months or more to finally hopefully get rid of the intermittent check engine light. That was a pain. I had changed out the three very, very hard to access T-25 torx screws with regular hex, stainless socket head cap screws when I did the regulator the last time. I apparently did not buy a Bosch regulator when I did it 10 or 12 years ago.
During the fuel pressure regulator swap I must've had the belt slightly off one of the pulleys. On startup there was a belt-tearing noise, and about 20% of the width of the belt ripped off and shredded. I've now ordered a new belt, tensioner, and two idler pulleys since none of them look/feel great both bearing and belt surface-wise (kinda crusty/rusty). Seems like it just doesn't end. Total this week is "only" about $200.
