ASE Master Mechanic Inspection

Hands-on tested before listing by MKF on February 27, 2025

ASE MASTER MECHANIC TEST NOTES & FLAWS NOTED DURING TESTING: (1 – RUNNING ENGINE TEST NOTES): Engine runs good with smooth idle and strong throttle snap. No smoke was observed and no major abnormal noises noted. Inspector mentioned a possible injector seal issue to be inspected further. (2 – POST REMOVAL INSPECTION NOTES): Long block overall looks good. Inspector noted the oil pan may be leaking and a small oil weep around the valve covers. One injector seal was confirmed bad, so the unit has been converted to a long block assembly. As always, recommend replacement of standard service and wear items (timing components, plugs, injectors, pumps, seals, gaskets, and filters) before installation.

ENGINE LONG BLOCK ASSEMBLY

First-start note: we treat every engine with fogging oil to protect the cylinders in storage and transit. A little smoke on first start-up is normal and expected — it should clear within about 30 minutes of normal running as the fogging oil burns off.
