To start this off I will explain my issue and what I have done so far. My truck sounds like it is running well but once it warmed up I would be showing very low oil pressure and would get a check gauge light when I came to a stop. So the first thing I did was replaced the oil sending unit which did not help my issue. I then preformed a compression test and came up with these results.#1-150 #2-75 #3-150 #4-150. At the current moment I have the valve cover off and everything looks decent I planed on pulling the rocket arms tomorrow and checking push rods and removing the springs and checking the valve seals. But other then that I don't know how far I should take this. The truck is in very good shape and only have 77,000 on it. I have another S10 2.2 manual with 220,000 so I know the engines can hold there own. Any advise will help
