2006 Honda Civic EX 1.8L Compressor engagement VIN: 1HGFA16806
First of all, thanks to everyone that replied. I'm going to shoot an educated guess at this one since it is so intermittent. I'm going to take the vehicle to Honda and let them reflash the ECM (since it is under 8yr/80k miles) then drive it for a week to see i...

2004 Land Rover Discovery SE 4.6L compression VIN: SALTW1943A
Thanks to those that replied, but I did end up digging deeper and continuing with disassembly untill I found the problem. My theory: Cam bearings #3, #4 spun and "walked" out of position, blocking the oil feed holes. Without lube, the rear half of the cam seiz...
