1 /5 Francisco Javier: UPDATE** I removed the cylinder head and found more extensive damage they did, broken valves, damaged pistons.. wow, im at a loss for words..i will mention that they did offer to try and diagnose it further, but it would cost us $600+.. then further charges for the repairs at more than $1000. so theyll destroy your engine then offer to repair...; Took an suv that broke down for a diagnosis... the guy poured used oil into the engine.. as one of the techs was scanning it and troubleshooting, one of his buddies, with no uniform, walks up, gets inside the vehicle and starts reving the engine until there was a loud pop and a ton of smoke shot out of the exhaust, they blew the motor. Then they had the audacity to say the engine was blown after that idiotic stunt. Im mad because theres nothing I can do about it. I towed the suv home, opened the valve cover to find a broken valve and ruined engine. If I could give 0 stars I would.
