This (no oil pressure coupled with valve lifters suddenly ticking) is a very
serious situation. Either your oil pump is not pumping or you have a spun
bearing. Either way, you have to drop the pan and take a look at things.
Do not run the engine at all until you do this. If you're very lucky,
you'll find the oil pickup float has fallen off or the screen is blocked.
More likely, there is a spun bearing - since you don't hear any rod knock,
it is most likely a main bearing. While you may be able to patch this up
and get a few more miles out of the engine, the right way to do this is to
plan on a complete engine rebuild. Sorry, this is bad news (unless, like
me, you enjoy rebuilding engines!)
