Lost the Engine in my 05 STS V8 today with only 115k miles on it. A couple thousand miles ago it threw a bunch of camshaft position sensor codes shop said oil needed changing (only had 5k miles on it) and this miraculously seemed to cure the problem. Fast forward to today (175 miles from home and on the way back from a 1500 mile trip) car started running rough then roughly 5 seconds later I lost all power. Had it towed to a shop in Montgomery and they said oil was silver, it was I saw it, and that it had 0 compression on 3 cylinders on the right bank and 50psi on the 4th. Best guess is it skipped timing and trashed itself. Car has never missed an oil change and never used any oil.. Tough pill to swallow. Having used engine installed (2008 with 93k miles) to the tune of $3500.
Here's my post about the initial problem.
