Calling all engine experts. My # 4 piston rings and cylinder wall are toast but the other 3 are fine. Compression is at less than 50% for # 4 and # 1 & # 2 are down about 20%. Dealer said it was most likely caused by oil starvation because I had ran it dry, did not change my oil or using aftermarket oil filters. Unfortunately none of the possible causes are true. They want $3800 to replace the short block!
Heres a short background. Before the recalled my engine sucked in a VCTS screw and blew the # 4 sparkplug. Took it to the dealer and they wanted $1400 to replace the intake manifold because it was a thousand miles past warranty. Since I didnt have that much money at the time I bought a used manifold and was going to replace it but the car ran find after it left the dealer so I kept the used manifold in the garage waiting for a rainy day. A few months later during a trip while driving in the middle of nowhere my engine sucked in another screw and again blew the number 4 sparkplug. Having no tools or plug I had to drive about 30 miles with just 3 cylinders until I found a gas station that could replace the bad plug. The car ran find after the plug replacement. A couple months later the recall came and my manifold was replaced.

About a month after having the recall done my oil light came on and my engine was down to about a quart of oil and it has been burning a quart of oil about every 800 miles since. was my engine damaged by oil starvation when it was down to a quart? I had changed the oil just a few thousand miles before the oil light came on so it had to have been burning oil excessively causing the oil light to come on. So my question is: Is it possible that I had damaged the # 4 cylinder by driving it without combustion and not by oil starvation? If not, then what caused the excessive oil consumption?
Any suggestions would be appreciated because I don't want to make the repair and than have it go bad again.<O
