Valve Adjustment

Hopefully this isn't the case. I'll know right away, as the lifters are marked with a number corresponding to their length. If I'm lucky, there will be at least one or two in there that will get me where I need to be with my adjustment.

They are not marked, they need to be measured.
Even IF they were marked, the numbers would be irrelevant due to wear, as you need to measure the gap, then the actual thickness of the lifter bucket, do the math for optimal gap, read the chart to see which replacement you will need.

It doesn't really matter to me either way. It'd be easy to mic all 16 and see what I have to work with. I can get them cheap, and my car won't have to sit for a week while I wait for the dealership to get parts. If I have one tight valve, there's a 1 in 16 chance that one of my used lifters will do the job. It's not rocket science.

1 in 16.

One tight valve. 16 used lifters on hand.

35 different sizes.
No, the factory ones are not all the same, they are sized to fit from the 35 available, at the factory.

Those of you commenting on this thread should please stop your squabbling. Whoever needs to adjust their valves, kindly do so and share relevant occurances during the proceedure. I started this thread in order to disseminate technical information as opposed to a bickering forum.
