An important PSA in engine maintenance: issues with timing chains and/or oil pressure need to be addressed ASAP. We recently wrapped up an extensive timing chain job on our customer’s 2000 Ford Expedition with the 4.6 Romeo engine. This truck came in making an awful clacking sound, and someone else recommended to our customer that he needed to change his timing chains so he brought it to us. Unfortunately, this job turned into something a bit more complex due to the excessive wear of the timing components, which caused further damage to the engine by clogging the oil-pickup and starving the passenger side cylinder head of oil. This caused the passenger side camshaft to seize, which then caused valve to piston contact (see video in comments). We ended up having to remove the head, clean out the entire engine and oil pan and oil pickup, install a newer cylinder head and new valves, and re-time the engine. This Ford is now back from the dead and running strong!

This Escalade came to us as a recommendation from another customer. He had an oil leak from the drain plug, which turned out to be an aftermarket plug replacing a stripped out OE plug. We recommended replacing the entire oil pan, and following a routine multipoint inspection, we noticed that the rear brakes and rotors needed immediate attention as well. The customer approved all the work and we completed the job with another satisfied customer. Thanks again for trusting us with your vehicle.
