-Hmm, well I wonder why I am studless then. Frustrating. I can look into adjusting the bracket, that's a really good tip! Would you consider it resting firmly on the bracket (on on a silicone pad on that bracket) to be an appropriate long-term solution? There wouldn't be a connection in tension, and there would be more strain put on the water pump fitting than if it were secured via a positive connection.

Did some work today. See pics of my improvised short term solution for the expansion tank. My car will be in an art museum for a month in a week and a half, and I don't have time to properly remove/repair the tank before then. A very ghetto repair, but now the tank doesn't vibrate out of sync with the engine any more. Drilled and tapped a piece of scrap pine (from a stake) for a spare bolt I found, then shaped it with a knife to fit with just a little upward pressure on the tank, then adhered a little pad of hi temp silicone to dull any micro impacts. And speaking of vibrations. See the p

Thanks so much for the ideas guys! And if during its last "repair" the stud on the bottom of the expansion tank was not brazed back on? Then what... And if it is there, should there be a washer between the tank and the bracket? Something was there before, judging from my pic. Or perhaps a rubber washer? p.s. Is the tank brazed together (what I had been told), or soldered? Because I can do the latter, have not attempted the former.

To excessively condense the story: I am taking back ownership of fixing my Avanti due to yet another incompetent mechanic. I have already solved several persistent leaks after discovering that certain transmission and oil pan bolts were not torqued to spec. And the upper dipstick tube was not connected to the lower, so the dipstick tip was just hanging in mid air. Fun stuff to discover 😒 I was chasing down the remaining leaks today and when I had my R1 (actually an R2 block with R1 innards, long irritating story) idling I noticed that the expansion tank was vibrating a lot more than the e
