it's not a thermostat spring, way too small of a diameter and too long. I've never seen a spring like that on the engine anywhere. Probably something was dropped in at the factory when it was assembled. Was the other metal piece in there too?
Looks to be part of the chain tensioner from the cylinder head.
Greg Brown got back to me and said he believes it is part of the early tensioner system for the cam chains. The heads were taken off this engine and the tensioners are in plastic bags dumped in a box. This is going to be a joy to assemble. I literally got a block, heads and bags of unlabeled parts. Oil pan was full of "mud", engine had been sitting uncovered in shop for 8 months. Lifters are in a box, loose. Cams sitting on bottom of box. Cam gear have two nicks in them. Gonna take a while to put this together figuring out what each bolt goes to, etc. Not happy at all with the shop that did this and I am doing this to help someone out who is in a bind. Don't even have a crank bolt so I can't turn the engine over by hand with the heads off so I can put assembly lube in there. What a **** show. Oh well. Just one step at a time and follow the WSM.
