6.1 Valve spring failure

72bbswinger - I did say shims on intake side only - locaters on all....sorry if what I wrote was confusing


Buschi - Yep that was me -

Compressed air is the safest way - the other way is to manually crank the motor around to the compression stroke for each cylinder - starting at tdc #1 cylindrr

This means every 90 degrees of crank rotation you change the springs and seals on the correct cylinder as per firing order.

As insurance, you can insert a long thin probe into the open spark plug hole - you will see it raise up as the piston reaches tdc in each cylinder - then you know its safe to remove the springs - this is hiw I did it.

BUT.....there will still be a small amount of valve drop..and this makes it trickier to get the locks on.
