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) |

3.6L right?
Hydraulic lifters? Hydraulic cam guides? What do you think the noise was? |

(IMG:style_emoticons/default/idea.gif) Lifters are at the end of the supply chain, so it's likely what you heard. Sounds like tapping an unsharpened pencil on a desk. Doesn't explain the pressure loss though. Since it recovered I'd check for sludge buildup somewhere. Cutting the filter open is still a good idea. It will answer the bigger questions. |
