You could tell that mechanic was fairly competent, a wee bit generous with the break in oil but eh!! each to their own. Now truck owner just needs to pony up for a new starter solenoid
Hope they did valve grinding and seating. Newly rebuilt engine should not have that tappet noise, it may become big issue if not corrected. Initial start-up smoke is normal and rectify itself during run-in but this guy is too generous with oil. No need to start over and over again, they should let the engine run for at least 12 hours. I think it's the same truck had the roadside clutch repair. I am not happy. It’s a bodged job.
