ASE MASTER MECHANIC TEST NOTES & FLAWS NOTED DURING TESTING: (1 – RUNNING ENGINE TEST NOTES): Engine runs excellent with smooth idle and crisp throttle response. Wide-open snap is strong with no smoke, ticking, or knock detected. Turbo spools quickly and holds boost well, with only a faint wastegate rattle on cold start that does not affect performance. (2 – POST REMOVAL INSPECTION NOTES): Overall one of the cleaner N20 engines we’ve tested. No major leaks or wear issues noted at teardown. Internals appear solid, and external components are in very good condition. This is a strong candidate for direct installation once standard service and wear items (timing components, plugs, injectors, pumps, seals, gaskets, filters) are replaced to ensure long-term reliability.

In-car test: ENGINE RUNS GREAT, VERY GOOD IDLE QUALITY AND WIDE OPEN THROTTLE SNAP SOUNDS GOOD, RADIATOR WASN’T HIT SO COOLING SYSTEM WASN’T COMPROMISED. PENDING A COMPRESSION TEST AND PHYSICAL CHECK THIS WILL BE A UNIT.

Out-of-car inspection: OVERALL ENGINE LOOKS GOOD, DID NOTE SOME OIL WEEPING AROUND VALVE COVER, REAR MAIN SEAL AND POSSIBLY OIL PAN, TURBO FEELS GOOD, VERY LITTLE RADIAL PLAY AND AXIAL PLAY IS MINIMAL. AS ALWAYS, RECOMMEND ANY SERVICE AND WEAR ITEMS SUCH AS TIMING CHAINS, BELTS, GUIDES , TENSIONERS, SPARK PLUGS , INJECTORS, PUMPS, SEALS ,GASKETS AND FILTER BE SERVICED BEFORE ENGINE BE PUT BACK INTO SERVICE.
