I had the timing chains replaced and the mechanic says the right side keeps failing what would make that happen
My car has 145000 miles.
My car has an automatic transmission.
The chain can fail due to lack of proper lubrication to the chain or camshaft on that side of the motor. I would recommend having the engine oil passages cleaned and engine oil flush used to try and dissolve any clogged passages and then use only 0w20 oil in the engine.
