Went to bleed the brakes today and rotate tires and ended up doing a bunch of little stuff that added up. Went under the hood and discovered the small nipple at the coolant tank had a crack and was leaking. Installed a used tank I almost sold last week to another BBer. Good thing I had it, hope the slight beginnings of a crack near the cap are going to be OK. Then noticed the infamous crack in the sheet metal at the strut tower. So I get out the welder and weld up, and repaint. fun. While the AFM is removed, I spray some TB cleaner at the shutter to fix a little stickiness. Start up car and hear a SSSSSSSSSSSS. Great, the elbow for the vacuum line to the cruse is split. Replaced with fuel hose. Not an elbow, but it will do and I am tired of buying these cheap Chinese elbows that last 1 year or so before they fail. Now I hear a SSSSSSSSSSSS coming from the vacuum tanks under the L front fender. No wonder this thing has been stumbling at cold start up for a few seconds for the past few weeks. Jack her back up and remove fender liner. Found the large vacuum hose to the round vac tank disconnected, no wonder the cruise has been inop. Also, went at the idle switch at the TB to be sure it was clicking just right at just off idle and back. Make a slight adjustment to that. Test spin around the neighborhood and WOW she sure is running great and much quieter without hissing going on. It always pays to raise the hood and give the 164 a little attention every now and then. She will flip 200,000 on Monday.
