[QUOTE=joshgold10;3036094]Well here is the bad news.

Could I have done this from adjusting valves incorrectly? Seemed pretty straight forward and done it a thousand times on my vw bus/bug motors.
Appreciate all the input here![/QUOTE

Basically impossible in my opinion.

I thought about this a little more. I guess it is possible but you would have had to set the lash clearance on other than the peak of the cam lobe. Yet if this was done the engine should not have been able to run. I might be missing something here but not sure of what. I still feel that in general if the engine was runnable after the lash adjustment it was not the causitive issue.

Actually in applying air the problem is having an adapter to match either the injector hole or the glow plug hole. Usually if I do not have something on hand I will gut a glow plug or spark plug and weld an air nipple to it. Once done it becomes a permanent tool. Normally I use one of my compression tester fittings. Use only low air pressure as otherwise the force will tend to rotate the engine. It still will try but not as hard say with 20 pounds pressure. To stop the engine rotating as the air pressure tries to push the piston down. Put the transmission into reverse and block the rear wheels. The higher the air pressure the more force is exerted on any piston that is not sitting at bottom dead centre.

Set the emergency brake and block the rear tires. Remember the remanants of the cam have to be pulled first so if all the valves are capable of sealing they will be. With no hydralic lifters either a valve bends or the crank tower lets go. It seems at very low rotational speeds the forced bleed down of an engines hydralic lifters may save the situation sometimes. With solid lifters or equivelant like the 616 has. Generally something has to be damaged.
