Since this is the technical page, I'll write some tech.
Last evening I started my '69 Shadow to the usual chorus of hydraulic pump noise. It fades away nicely as the car began to warn up. Once warm, there was just a ticking sound from the rear pump area and nothing more. The rest of the engine is quiet and smooth as soft butter!
I've owned and had possession of the car for 1-1/2 days now and have made a few assessments. (I believe in the philosophy of 'Diagnose BEFORE surgery.')
Over all, the car is better than the PO promised. The new-ish interior (upholstery, headliner and carpet) is better than any car I have ever owned - including my new Mercedes daily driver! The paint is excellent and with a polish and a coat or two of Ice, will be even more like glass. The wood is undamaged (except one little repairable spot) and just needs polishing. And the car drives great.
And of course, its not perfect. There are lots of little fun things to fix - and I really love putting these kinds of things back right. I'm a details kind of guy. The seat control switches are very stiff and need cleaning. Driver's seat drive motors run but are not operating the seat properly. Rear passenger window, right hand side does not work. All locks need graphite lubrication and their mechanisms need lubrication. Radio is missing. Master window control switch is stuck in 'emergency' position. Rear defogger switch is stuck 'on'. And on and on it goes.
My usual work plan is to photograph, clean and diagnose THEN begin repairs starting first with those items that affect usability. For example, I am having the A/C repaired and charged tomorrow. I'll then pull one of the blowers out to clean, lubricate and find the source of a little fan-hitting-a-leaf-like noise (probably remedied by the 'clean and lubricate' step).
I've written a book. Sorry. I'm just excited. Thanks for sharing.
