Let me start off by saying thanks for having me on the thread. Merry Christmas. I hope I can both be active and helpful and get the help I need from time to time.
I have an 03 5.7 Hemi 4x4 4 door with 198k miles has been my daily for over a year. Has always started first turn and motor wise has never given me a single issue. My 19 year old was driving old reliable to work driving 55mph down the road and she stalled. We towed her back to the house couldnt get her to restart and did a compression test. She is showing lower than 5psi on every single cylinder 4 she is showing no compression at all 4 she is showing below 5psi actually. She did not smoke, use oil, make any noises that she wasnt supposed to. Did not have a loss of power or anything that would suggest worn rings and even though sudden loss of all compression in all cylinders while driving perfectly normal would be very odd wouldnt it? We thought exactly what you are currently thinking pulled the valve covers and turned her over by hand all rockers are moving as they should, we pulled the timing chain cover and chain and tensioner look good and timing mark's are aligned as they should be. So I am at a total loss at this point. We did a wet test of the cylinders still nothing for compression. Was running strong and normal when it stalled cooling system was fine, was not smoking at all, anybody got any ideas as to what could cause a sudden complete loss of compression on all 8? What's stranger the 4 cylinders at the coeners of the block are the ones that are getting the 5psi and the 4 in the center are the ones with absolute 0 psi. Any help you could give would be appreciated I have been reduced to driving my old Chevy CK 2wd until I can get this figured out.
