- Scanned vehicle and found DTC's P052EE0 and P227900. Both codes are related to PCV system performance indicating an issue within PCV. With engine running, observed excess Crankcase vacuum and noise dissipation by pulling oil cap and releasing vacuum pressure. After further tests were completed we have determined that the PCV has failed and is needed to be replaced at this time. We will also need (6) intake gaskets for the repair as well.

2015 Chevrolet Silverado 2500 HD
Mileage129,344Service Date10/8/2025Services Performed- We were able to get the vehicle to long crank. We scanned the computer and found no codes present at this time. We then started to inspect the engine area and found that the fuel filter primer head was leaking. We began to remove the head of the primer and smelled gasoline! Upon further inspection we have determined that there is gasoline in the fuel tank. We need to install a new fuel primer kit, drain the fuel tank, install some diesel fuel, and retest. Note: the leaking primer most likely saved you from engine and injector damage.

2011 Ford F550 Super Duty
Mileage262,645Service Date10/7/2025Services Performed- We first scanned for codes and found an open circuit code for all 8 injectors. We then removed one glow plug and checked the resistance in the glow plug and found that it is with specification. We then cycled the ignition on with a multi meter connected to the glow plug wire and found it did not have power. We then un plugged the glow plug control module and found no obvious faults or bad connections. We then checked the wires at the control module to the glow plugs and found that they all had an open circuit. We then located a brake out connector in the engine compartment for the glow plug harness. We checked it and found it was not plugged in correctly. We reconnected the brake out plug and retested the glow plugs and found that they are now operating according to specification.
- We scanned for codes and found a invalid data received code in the ECM. We then checked for power and ground at the ABS control module and found both are present, we also checked wiring near the module and under the hood related to the ABS. We then test drove the vehicle and monitored live data and found that the speed sensor at the differential is erratic and momentarily drops off. We need more time to properly diagnose this problem.
- We put the vehicle up on jack stands and unplugged the speed sensor, connected a scope to the sensor and found a normal wave form with the vehicle in drive. We then monitored wheel speed data while wiggling the the harness for the rear wheel speed sensor. We found that the signal stops when pulling on the harness. We found a faulty connector in the harness in between the fuel tank and the frame. We repaired the harness, test drove the vehicle, and found that the wheel speed signal is now consistent, and no codes returned.

2012 Ford Fusion
Mileage85,125Service Date8/8/2025Services Performed- We went to test the a/c and found the vehicle will not blow air at all. We then went to visually inspect the blower motor and found the connector to be worn out causing a bad connection. With slight pressure we could get the blower to work but it is very weak indicating a worn blower motor as well. We recommend replacing the blower motor and connector to start. After repairs are made we will continue to check the a/c system to make sure it is blowing cold. After our repairs were made we found the a/c system blows cool but not cold we then with a black light inspected the system for leaks and found a hose that goes from the compressor to the condensor is leaking. This piece also has a seperate line that goes from the compressor to the line with the low side service port on it and it is all one piece. We recommed an a/c service and replacing the line assembly.
- BLOWER MOTOR ASSEMBLY -and Replace the blower motor connector.
- AIR COND HOSE – Remove & Replace – Suction & Discharge Hose Assembly – [DOES NOT include Air Conditioning System recover, evacuate and/or recharge.]
