Just a heads up for anyone considering the English made shrouded push rod adjusters for the AVL that are said to prevent the standard adjuster from jumping off the lifter (which I'm sure they do).
They are a son of a bitch to install. These adjusters (because of the shroud) make the overall length too long (at their shortest) to install without lifting the head to make the distance between the rocker & the lifter longer. Which is what I did (because my nuts weren't on yet). Then I removed my shims, let the head settle on the push rods & the head lowered itself as I adjusted the push rods to the correct length. I needed 3 more hands, but slowlee, slowlee, catchee monkee.
The only other way I see you could do it (with two more hands) would be to pry up on the rocker in some fashion (opening the valve) & slipping the push rod over the lifter & then into its socket on the rocker. No way could I do this alone.
Things go well, but it's very difficult & I'm on a different schedule than you healthy, uncrippled bastards
so don't give me any shit, please.
Later today when I can move again I'll torque the head to 15, adjust the valves & crank it over veeery slowly & pray I feel no resistance for two full rotations. Then remove the head & read the tale of the clay. And if all that goes well, put it all back together again.
I'm considering going back to the stock adjusters for the 2nd assembly. There's no drama with them at all; zip zip & done. Very simple.
