Ok car has been in garages for the last 7 months due to accident where it slide off road and landed on a man hole inside the rear passenger wheel. It destroyed the under shields and busted the front radiator. Well 7 months later when I go to move the car, its making a squilling noise, like its not getting any oil. The oil pressure gauge isnt even moving. The porsche dealership is looking into, sad the oil pump isnt pumping and they didnt know why. They pulled the oil pan off and it was full of metal shaving, she stated it looked like the gravel in the bottom of a fish aquarium. They said it wasnt uncommon for the intermediate shaft to break or soemthing and was probably the problem; stating complete engine rebuild. The insurance company is reevaluating, but has so far denied paying for any more on this. Thing is when the car went in the mechanics doing the original work (place is major bmw dealer in raleigh nc, over 150 miles from me) replaced the radiators and noted no other additional problems. Why all of a sudden or what could cause this no oil pressure or oil pumping problem from the accident. Please help.

HI there,

With out having the advantage of viewing the engine first hand, this is a bit hard to comment on, the pump may well have already been on the verge of failing, running with minimal pressure, the debris in the sump is from prolonged oil pressure problems and gradual bearing failure, the pump shaft may well have nipped up after such a long period of no use (possibly because of the lack of oil pressure) and totally failed on the initial re start attempt, I do not feel that the accident is the cause of the engine failure, and I feel that the insurance co is of the same mind, I feel that you would have been looking at a engine failure regardless of the accident, but the Porsche dealer will be able to diagnose this with the engine apart far easier than in can from afar.
