tried to crawl around under the truck but couldn't find nothing between the grease and just not being able to see up there very good. Anyway I am going to try to put a picture of the numbers on the pad by the front of the right head next to the water pump. If these numbers tell anybody anything I would greatly appreciate hearing about it.
