nope, carfax came out clean. Only mod on the car when I bought it was countersunk shift knob and gutted airbox with k&n filter. Leads me to believe there may have been other mods on it before he decided to sell it. I'm leaning more towards the engine being taken apart before and not reassembled correctly. ie- loose bolts holding cam caps to holders.

Check for crankwalk ! Ive seen this before . Thrust bearings got chewed up and spit out causing loss of oil pressure . Scary part was the owner had no clue . Drop the oil pan and take a peek .

Kinda wishing I had an AP1 right now lol...Coming across a lot more engines/heads for a ton cheaper. Besides Ebay/craigslist, where does everyone get their engines?

I've got an '05 with 56k miles on it. Engine ran perfect until 2 days ago.
I was on my way home from work and the engine died while slowing down for a stoplight. It looked like the alternator quit because I had battery power but couldn't restart the car. I pushed it into the repair place right where it broke down and they put a new battery in in the next morning, said charging system checked out perfect. I picked it up on lunch from work, ran a few errands before I left work to go home for the day, running like new again.
I was about 5 mins from home on the interstate, and I dropped into 5th to pass slower traffic, and power felt much lower than normal...I thought I was going crazy and moved back over to get ready to get off to my exit.....and the car dies. Before it comes to a stop, I tried popping the clutch to refire, thinking it was another battery/charging issue at the moment. I call the place that worked on it the night before to try jumping it(doesn't work). They tow it back to their place, pop oil cap off, and when we turn the engine over the intake cam isn't spinning.
To cut down on the story, the timing chain is alright, but after taking the valve cover off it isn't good. Exhaust side is perfect minus slight scoring on one cam holder. On the intake side, the nut holding the cam gear to the cam is loose, the bolts holding the cam caps to the holders, most are loose or finger tight, all cam lobes are scored heavily, and the journals are destroyed. At the moment, everything else looks good. I'm going to check down in the cylinders here in a bit to see if there is any debris on top of the pistons, but I haven't seen any in the head. Has anyone heard of this before or dealt with it? not sure if those bolts backing out led to this and the cam gear stilling spinning with the timing chain spun that nut loose, or if I'm looking for a clogged oil passage.
