I checked all the hoses while I was under the hood, and they still look good and feel good -- no cracking, not too flexible, not too hard.

I think I'll leave the hoses in there just for the coolness factor of having the original GM hoses under there. I like vintage cars -- I check Hemmings out of the library regularly and read everything in it, I am subscribing to Hemmings Classic Car, have read Cobra in the Barn, Hemi in the Barn, and Corvette in the Barn, etc. I am a big fan of survivor cars, and the Buick actually gives me something a bit like that to mess with . So everything is staying original unless it must be messed with (like the spark plugs).

I had the unenviable pleasure of changing out the original plugs on a 98 GM recently. Only 160,000 on the odo. Hardly anything left of them, more than double the original gap. No discernible difference in performance.

Ew. No discernible difference in performance? Is the engine tired?

Wow, I had to go somewhere early this morning, and at an ambient temp of ~0, it started (almost) right up. HUGE difference from the extended cranking i was getting in the teens before this.

Engine is tight. Was just doing a round of long overdue maintenance.
