I'm new to this group and I have a question. I have a 68 with a 350. It I was unexpectedly parked for about 3 years. When I started it again it wouldn't idle it had no power. I found water in number four cylinder. I pulled the motor to replace the head gaskets and to clean it up, and found a lot of corrosion, timing cover is eaten through in two places. I also found pieces of tiny spring similar to the tiny spring found in the timing cover seal. The timing cover seal is whole. I can't figure out where those tiny Springs came from and I'm ready to start reassembling this motor. Have I missed something obvious?
