Cylinder head kinda week!!!!!!!
1. Warranty head gasket job 6.7 Cummins
2. Completely blown head gasket “look to see” 5.9 Cummins
3. Cracked exhaust valve 6.7 powerstroke

Some may ask why would you post doing a warranty job. Well it’s simple, we are all human and mistakes can and will happen. The difference is we don’t run from mistakes, we step to the plate and make it right. That’s what sets us apart from most

The 5.9 Cummins came in running absolutely terrible after it had injectors thrown at it from another facility. A simple compression test revealed low compression in cylinder 4 and 5 indicating compression mix between cylinders

The 6.7 powerstroke came in with a miss in cylinder #4 and was told he needed an engine. Upon diagnosis we heard a popping coming out of exhaust. Performed compression test and found cylinder 4 was 75 psi under spec and failed leak down tests. Instead of assuming we pulled the head and found the exhaust valve cracked and bleeding compression. Needless to say the customer was more than pleased with our findings.

Know your mechanic and do your research before choosing a facility.

Well here goes nothing, we are looking for a highly motivated individual to join our team. Yes, this means you have to show up and want a JOB. Hours are 6am to 5pm Monday through Thursday. Health insurance, retirement, vacation and tool allowance included. No, we will not alter your hours to fit your schedule. Pay is negotiable depending upon experience, do not ask for premium pay with a minimum wage work ethic. A positive attitude is a must as we are not here to be your mom or dad and hold your hand. People come to us as the professionals so if you are the comeback king of repairs this position is not for you. We have fun at work but get things done and done right. If interested please either shoot us a message or call the shop at 636-775-1077

Ps....if you’ve been sitting on unemployment for the last year while being perfectly capable of working, you will not be hired no matter what qualifications you have.
