Stay clear of this shop for motor repair or engine rebuilding. Poor mechanic work. They make excuses vice doing good work. They ruined a new engine build. Charged me for new parts that were not actually used. When i picked up the motor it looked sloppy and i had a bad feeling. I took the motor to another machine shop to have it inspected and the result was sloppy work and even broken parts. Mark the owner did not think i would go behind his work. If i would have installed the motor it would have blown and I sm sure Mark would have blamed the insulation vice his sloppy work. Mark installed the cam wrong and broke a side crank main cap bolt and did not put the 2 rear pan bolts in but instead filled the holes with silicone. If I had installed the motor and tried to start it he would have blamed me.

Mark's is a place for good hard working mechanics at a better than fair price. He's been fixing my stuff for nearly 30 years. Of course all the diagnostic plug in stuff, but with regular vehicles especially GM products,,,,most of the time he can listen to it and feel it and tell you with 95% accuracy what the problem is. Also, if the repair is going to be above certain dollar amount, he will call and let you know and get the go ahead from you. + Remember Mark is an Engine Builder/Machine Shop !! "So Let it be Written." lol.

Where to start? Unprofessional in every aspect. Quoted my repairs to take 6-8 weeks. Took 21 weeks of me hounding just for it to get done, only to find out an additional $900 worth of work was done WITHOUT my knowledge or consent. Had I been informed, I would’ve had the money ready but go figure, I needed time to collect it. Mark then proceeded to barrage me and my wife with calls and threats of a lawsuit in less than a week. Do not go here unless you like getting screwed over.
