Low oil Pressure led to replace timing chain now aluminum in oil pan on 1999 Mercury Cougar

My Low Oil pressure light came on and I dropped the pan cleaned out the Oil Pump intake screen and the car ran for a day. The Timing Chain was slaping something, so I had that replaced. I was driving on the highway (one day after the timing chain and guides were replaced) and the car died. I now have low oil pressure and the car sounds funny when running (when it decides to start). I dropped the pan again only to find aluminum in the pan. It could be the main bearings but I thought I would hear something catastrophic. Could it be something the mechanic did when he put on the timing chain? Any Ideas?

Your best bet is to return to the shop that did the timing chain. I'm concerned that you had them perform a major repair and your car is not running properly after that repair--that shouldn't happen, and since they've had the engine apart, they are in a better position than anyone to diagnose.
