By adjusted I assume you mean valve clearance. I didn’t bother reshimming. They were all still within spec though. More on the loose side than tight. If it was a simple process I would have improved the clearance though. I kind of wrote it off as the valve not seating well, engine being cold and dry and the fact that I was turning it over buy hand rather than by the starter. It was a big discrepancy though and it was all leaking past one intake valve.

hmmmm…… one valves hooks over the other valve and the piston comes up and smashes the hell out of both of them - :eyebulge:

Why did we ever get away from big block engines - enough room for everything - :confused0068:

Yep! And a valve job consisted of a couple of gaskets and a whole two hours start to finish.

Yep, valve clearance.

Let's see, you have one hand trying to hold the compression gauge in the spark plug hole tight - then with the other hand you are trying to turn over a cold, dry engine.

Now, HOW could you get a false reading?? - :D

Back in the day, it took me both hands to hold a compression gauge in a spark plug hole (on a 8:1 compression ratio engine) - :iono:

(hesh up, @Tcoat , I was NOT a 98 pound weakling - I just weighed 98 pounds)

Yep, the old days. I used to take off the head(s), put them in the truck, before school, drop it (them) off at the automotive machine shop in town, have the head(s) milled (actually trued), valves replaced or ground, buy a gasket set, borrow a torque wrench, take them back to the farm, install the head(s) adjust the valves, all after school.

Actual work time, not much more than two hours - :happyanim:

I have threaded fittings on my compression and leak down gauges so that helps.

Back at the dealership today...addressing new suspension noises that weren’t there before safety recall work...loose bolts on sway bars is my guess
