Vehicle presented with engine noise concerns. Repair facility had already performed partial engine disassembly for inspection.
Upon inspection, the valve cover had been removed by the repair facility exposing the valvetrain components. Visual inspection of the camshaft lobes revealed abnormal wear and scoring on multiple camshaft lobes. Wear patterns were observed on the camshaft surfaces consistent with internal valvetrain component deterioration.
Engine oil observed on the dipstick was dark in color. Further visual inspection of the valvetrain area revealed evidence of metallic contamination consistent with internal engine wear.
A magnetic inspection tool was placed into the fluid sample and retrieved a substantial accumulation of ferrous metallic debris. Metal particles were present in quantities exceeding normal operational wear and are consistent with internal component failure.
Transmission fluid sample was dark red to brown in color and exhibited signs of fluid degradation. Magnetic inspection revealed metallic material suspended within the fluid sample, indicating internal component wear.
UV dye inspection revealed fluorescent dye present at the condenser assembly. Dye evidence is consistent with refrigerant leakage from the condenser.
Visual inspection of the front suspension revealed deterioration of the strut dust boot and evidence of fluid leakage from the strut assembly. Condition is consistent with a worn and leaking front strut.
Based upon the visual inspection, magnetic inspection findings, and observed camshaft wear, the symptoms demonstrated are consistent with internal engine failure. Significant metallic contamination was present within the fluid sample and abnormal wear was observed on camshaft lobes. These conditions indicate internal component deterioration requiring major engine repair or replacement.
Additionally, the transmission fluid condition and metallic contamination are consistent with internal transmission wear. Further teardown and diagnosis would be required to determine the full extent of transmission component damage.
The A/C condenser has failed due to refrigerant leakage, and the front strut assembly has failed due to leakage and component deterioration.
