I had the original motor and it lost a cylinder. Got with a mechanic and he had a place that he buys thru that comes with a year warranty for parts and labor. First motor they sent never got put in, second motor did. It ran about 100 miles and it sounded like it was about to fly apart. Took it back, said the valve train was bad. Third motor was put in. Said it had an exhaust leak and would go away when it warmed up. Thought just freaking great, but at this point I’m still out $4500. My truck had been down for 2.5-3 months at this point. I had some side gigs that needed done. Drove it with the supposed exhaust leak and knew right away it wasn’t an exhaust leak. It was more of a peck than a leak. Got somewhat caught up and took it back. 4th motor was installed shortly after. This motor that’s currently in it has been decent, but I’ve only put about 5k miles on it.
And no, unless it’s warranty work on this motor, he’ll not touch another vehicle of mine.
