Due to this head being nearly impossible to find combined with incompetent machine shops in my area....
I am in the process of rebuilding the head for the subject vehicle. I lapped the used valves I put in (previous valves bent at idle from defective OEM tensioner) and then gasoline tested for leaks and there were none. Yes, I removed the lapping compound.
I cleaned up everything, installed new valve stem seals, old springs from another head, old retainers from another head, used cams from another head, correctly oriented old cam caps, and keepers. I lubed those parts with a coating of Rotella T6 5w-40.
I am about to do some lash adjustments with guess what? Used buckets.
I have lots of different lubricants laying around but no engine assembly lube. With all of the variables involved, the backyard head job and a high risk of another timing incident on this interference engine would you just lube everything up with RT6 and see what happens or would you go with assembly lube? If so, which one?
