So I pulled off the valve covers on the Spyder today and set her up close as I could to TDC on #1 to check the valve lash, understanding the "loose zero" means the pushrod should spin more or less freely but there should be no gap between the rocker arm and valve stem. Seems easy!
But, reaching down with my nitrile-gloved fingers to spin the pushrods, I couldn't at first rightly tell if I was spinning them or not.
Then I was pretty sure I was.
Then, reaching to the #2 cylinder bank, and later on the other non-set-up valves, it seemed I could spin any pushrod at any time—even those that were pressing pretty hard on compressed valve springs!
Made me a little paranoid about the whole process. Feeler gauges I get; used to do Bridget's stock aluminum pushrod/valve lash jobs in half an hour. This seemed harder, in terms of knowing if I got it right.
Can anyone advise me?
