Finished the last of the valve stem seals today. So satisfying to have that all complete and without any real hitches. I only dropped two valve keepers during the entire job and both ended up right on top of the little brushes that come with the AGA tool kit to plug up the oil passages. I also bumped one of the intake cams followers off it’s spring and it took a bit of head scratching to get it back on, but once I figured out a good method, it went on pretty easily. A nice long pair of pliers helps to compress that torsion spring.

Now I need to replace the driver’s side upper timing cover, and then re-assemble everything, start her up, and pray there aren’t any leaks!
