2003 V6, 145K miles, very well maintained service history. Engine just out of nowhere started making a lot of noise and Check engine light came on Codes areO300, PO301, PO302, PO303 mis-fires on cylinder 1,2 and 3. PO316 misfire detected on startup. Noise coming from valve covers on left bank, sounds like Timing Chain Tensioner or Guide has failed which is allowing the chain to move around and hit inside of engine per the mechanic. To fix engine must be removed to gain access, the mechanic recommends new engine due to time to remove and repair whatever damage is revealed.
Question, can the rear timing chain be service w/out engine removal? Does his conclusion of issue (based on listening with stethoscope) source make sense? Dropping $6-7K (17 labor hours) for new engine is not going to happen. Mechanic also stated special Ford tool required to perform timing chain alignment/change, which they do not have. Anyone have experience with this repair regarding cost, time, materials, etc.. appreciate any insight or guidance.
