Got stuck in traffic on my way home from work today and didn't notice the oil light until the engine started making horrible noise.
Did the only thing i could think of which was to pull onto the side strip and get on the gas hoping to get oil pressure back. That actually worked! Pressure went back up to ~80 under load and ~30 at idle for the rest of the drive home but i'm afraid i might have done some permanent damage. By the time i noticed the engine noise and the pressure being at zero i was probably already running completely dry. (IMG:style_emoticons/default/headbang.gif) Now the real question is, how the heck did that happen? I checked the oil after i got home and it's still all in there. All 16 quarts of it. Could there be a blockage somewhere? Stuck piston? Clogged filter? (IMG:style_emoticons/default/sad.gif) |

The oil filter canister should have a spring for oil bypass if it gets clogged so that probably isn't it. . The oil filter base assembly has a pressure bypass also. . Scavenge pump and pressure pump are always turning so oil should be returning to the oil tank always . . . the bypass valve on the side of the engine case is the over pressure bypass valve that bleeds off excess pressure right out of the oil pump . . there is another over pressure on the bottom of the sump which is the end of the oil supply galley. . . either of those could bleed off some pressure but i wouldn't expect a total loss that returns when you reved the motor. . that is puzzling. .
I would pull the sump cover off and see if the wire screen is plugged at the oil inlet tube. |
