Thanks for the inputs.
Yes, I was looking at Chris O’s offering. Just wanted to be sure.
Fiatmonkey, I will probably be having a go at it as soon as I source the tool. So a week or two.
I checked the clearances last Sunday and have two exhaust tappets and one intake tappet that are out of bounds. But until I get the tool, I can’t measure the old shims and get an accurate idea of what shims I need to get back in spec.
Up until recently ( a decade) I had a Fiat mechanic that always did it for me, which saved time and headaches. But, sadly, no longer. In Albuquerque you are on your own. Mechanics in Albuquerque react to Fiats rather like vampires to a Holy Cross.
