Re: [T3] valves


BenW=> The distributor seemed to be backwards

Type 1 distributor?
Distributor drive installed incorrectly?

Bottom line: if you can time it freely, ignore the rim mark and live with it
until you can fix it *all*.

=> All the valves adjusted perfectly, except on
=> cylinder #2, ... it fell out of the head and the
=> valves were still too tight

Both exhaust and intake, right? One thing -- you can feel when you're
turning the screws under spring pressure -- those springs are *strong*. Was
it like that?

Well, first doublecheck that you have the right crank position, of course,
but I don't really expect that's the problem. If you're positioned
correctly, the procedure went right on the other three, and you're
communicating the problem clearly, I can only think of a few things it might
be.

Push rods too long (way unlikely, but easily checked)

Wrong rocker arms (ditto)

Rocker assembly somehow installed wrong (hard to do and get this result,
especially on only one cylinder -- make sure it's square to the head)

Valve seats recessing bigtime (on both intake and exhaust, and only one
cylinder, would be unusual; the springs would be obviously sticking farther
out than the #4 springs) How long since the last adjustment?

I had a situation a while ago on my Type 4 engine where the keeper splines
broke on a couple of the valves and the valve stems slipped a little bit up
into the springs.  This made adjustment just about impossible because the
springs were running into the rocker arms. You might check again that you're
able to measure against the screws and you're not getting hung up on a
spring or something.

Now somebody else tell us what I missed.
