Didn't know readings like that can only be a few valves. Not very knowledgeable on that. Some of the things mentioned may not be feasible for some owners to do. I have asked him two days ago to take off valve covers and when his business schedule permits, he will. I can't assess or train what to look for over the internet. Tearing down in his driveway scares me. I believe I'm just going to say a general statement that it seems like timing chain or other associated parts. Not recommend a DIY or go to a shop or get a Chevy motor. I will answer any questions after that and stop trying to find and fix. I will recommend returning to Stovebolt with a new post and explaining the problem and history of tests. I am not qualified to help with a teardown over the internet. If I was doing it I would take off bumper, grill, radiator, radiator crossmember and etc. to sit in a chair and pull all the stuff off the front of this Big Block 305 V6 monster. But not out front in my driveway, which is where it is stuck. I've had several of these motors. Solid lifters. If the rockers are in tact, springs in tact, everything going up and down OK with motor cranking, then unfortunately it's Kings X for Jimmy. Painful as it is, a decision will be made on how to continue..........
Can someone tell me if a blown head gasket can give these numbers??????????
Would it do any good to squirt a little oil down each cylinder in case ALL the rings are stuck or not sealing? Again it seems like all cylinders can only exhibit low numbers due to chain or gear failure. The thing that puzzles me is we check timing regarding no. 1 compression stroke and rotor position. We rotated around twice to see if rotor returned, it did. Although I was not there, it seemed he did it correctly. Yet it won't fire once. Has spark, has gas, seems timed but no compression. Does that point to head gasket??????????? Can all cylinders be "washed"???????
