Adding this to this thread just because that's where I left off. Sent my injectors to Mark for the rebuild. Don't get me wrong, I LIKE to do everything myself. I can see no reason why anyone would ever do this procedure themselves when you can have someone like him do it for you as well as he does, as reasonably priced as he does it, and he's fast. I always thought the car ran well, it now runs better than that. My injector bodies looked like hell, came back looking new with my Monark nozzles installed and balanced/popped. I'm happy Thanks a bunch & I'll get them done in another 75K !

The new pinion seal is still fine, don't ever reuse that nut!
