Oil Pressure Woes

Just read this thread.... you are one lucky dude! No actual oil pressure for 2-3 minutes will wipe out multiple (or all!) bearings. It must have been dribbling some oil into the lower end to survive, but not enough to get to the heads and show on the guage. I'd never let an engine run more than 10 sec with the guage at zero and I get panicky after 5 secs!

You must have really cleaned a lot of gunk out! I'd be doing a few more changes in short order.
