Big weekend for all of my cars but the Denali in particular...
Checked and un-kinked the horn wiring underneath the airbag as my horn had stopped working (but worked if locking the truck). Got horn to work.
Dropped off for new tires and Virginia safety inspection. Got Michelin LTX M/S2 tires since the truck is just used for bad weather and towing, no off-roading.
Noticed it was leaking oil a bit more than usual (alarmingly so) the past few days and didn't have time to check it out myself, so asked the shop to look after they did the tires. It was leaking from the valley pan gasket and the oil filter adapter gasket (where the oil filter "holder" mates to the block, I guess).
I paid them to do the oil filter gasket as well as an oil change, since it was due for it and I knew of the valley pan leak (it's a slow leak that ends up being 1 qt every 3500 miles). Expensive shop bill at $505 but given all I had done... Not too shabby.
Off to VIR with the racecar in tow on Thursday!
