ok last night on the way home from work i noticed the oil pressure light flicked on for a split second when cornering so checked the oil level today and although the engine was cold the level was full. drove to work this afternoon and there was no warning light. i had my stereo on loud so didnt notice any unusual noise untill i got to work (12 miles) when i turned the stereo off and heard the engine was rattely. checked the oil before leaving tonight and it was bone dry not a drop in it. no oil had leaked onto the floor, there is no oil splashed around the engine bay, the filter and sump washer on on tight with no trace on oild on the filter but some (looks like it been there for a while) oil on the sump. i have had to leave the car at work and plan to but some oil in it tomorrow and strike it up in daylight to see if there any any leaks. anyone had this before or have any ideas what to check. the car was running fine when i drove it to work so i dont think (and hope) its hasnt blown a con rod.
