So I went to look at it. It definitely rattles and clanks but it doesn't sound like it's all in the engine. Almost like a heat shield underneath, or something is loose. Here's the odd part. The timing cover, fans , and accessory belt were all off the car. Owner said some work has been done on the coil pack. The grenade pin was still in the tensioner. The owner wasn't sure if any timing work had been done....which with the grenade pin still in the tensioner, I'm pretty sure that has been replaced. I think I will pass, but part of me thinks it could be put back together and revived with some work.
