Hey guys, first time posting, just joined the community.
Back in January (2017) my main pulley on the timing belt sheared out that bolt from the engine and the pulley was being knocked against by that metal cylinder behind the main pulley (don’t know what any of it is called). They replaced all the pulleys and tensioner and such.
Now several moths later: the tensioner just came loose and shredded the valve heads and my engine is done for? Kaput. I had it towed to a mechanic (I am out of town so an unfamiliar one) and he said the part must have been faulty (i.e. the tensioner). If the mechanic previously installed a faulty part and it caused my engine to shred itself, who is at fault? Does the part manufacturer pay for a new engine? Does the mechanic? Do I???
