Recently purchased a 1986 K5Blazer for my 16 year old (to get him out of an MG Midget death trap) and we have a few questions. paid $900 for a non rusted good runnig vehicle with decent paint and interior that needed cleaning only 305 engine with 195,000 on it and the only oil leak I can see is from a valve cover at the oil "tube" on the cover (where oil is put into the valve cover) We replaced a non functioning water pump and have a oil pressure guage that doesn't register. the valves do not clatter excessively which leads me to believe that the oil is getting to the valves/tappets. I intend to start easy and replace the oil pressure unit on the engine this weekend, to see if that makes a difference. the truck runs good except for this problem. How worried would ya'll be about this problem? next I have electric windows and the drivers side is not moving despite hearing the motor work. Can I purchase a real honest-to-God shop manual for this vehicle or are we stuck with the Chiltons/.Haynes books. these two books pretty much (especially the Chiltons) refuse to discuss too much AC stuff (well..Haynes does some) and not any electric widow problems at all, ie troubleshooting these problems. We know that we really have stolen this vehicle and have a ton of plans for it. How lucky for a 16 year old, eh? Bet ya Dad re claims this when he gets outta high school. I just wanted him in something tuff and safe rather than the sardine can he was riding in. thanks and looking forward to corresponding with everyone. Bob Hollingsworth Red Springs N.C.
