excellent writeup on the valley pan gasket and the coolant pipe. took me about 8 hours total, but then I'm already familiar enough with this damn engine that I wasn't going through it the first time.

RE the valve stem seals; I did mine at 107K. it was a serious PITA, but I did not remove the engine or raise/lower it. with some luck and quite a few 4 letter words I got the last few seals in place
