ASE MASTER MECHANIC TEST NOTES & FLAWS NOTED DURING TESTING: (1 - RUNNING ENGINE TEST NOTES): Engine runs good. It starts right up, idle is nice and smooth, and wide open throttle snap sounds good. The oil quality looks good but on cold start there was a puff of blue smoke from tail pipes but i suspect it's a turbo oil feed issue so I'll inspect once out. There are no unusual noises from operating engine besides the typical slight wastegate rattle on cold start; (2 - POST REMOVAL INSPECTION NOTES): Engine overall looks good. Valve cover gasket does appear to be weeping oil and as suspected I have confirmed the oil feed issue as there is oil on the exhaust turbine so it will need the updated feed line with check valve (This is a very common problem with the n20 and n26 engines) The oil pan also does not appear to have any leaks. The turbo itself feels good with minimal radial or axial play The waste gates have the typical amount of play. Overall a nice looking engine assembly.

Output under load

WIDE OPEN SNAP GOOD

Oil quality

YES

Smoke from tailpipes

YES, PUFF OF BLUE SMOKE ON OVERNIGHT COLD SOAK (WILL INSPECT TURBO)

NONE

Turbo notes

SLIGHT WASTE GATE RATTLE ON COLD START

Noted: YES SEE COMMENTS

Note: WILL NEED UPDATED TURBO FEED LINE WITH CHECK VALVE.

In-car test: OVERALL ENGINE LOOKS GOOD, RADIATOR WASN’T STRUCK SO COOLANT SUPPLY AND OIL COOLERS WERENT COMPROMISED. DID HAVE A PUFF OF BLUE SMOKE ON LONG COLD SOAK, WILL INSPECT TURBO AND TURBO FEED LINE (SUSPECT IT WILL NEED UPDATED OIL FEED WITH CHECK VALVE INSTALLED. PENDING A COMPRESSION TEST AND PHYSICAL CHECK THIS WILL BE A UNIT.

Out-of-car inspection: OVER ALL ENGINE OUT LOOKS GOOD. DID NOTE A SMALL OIL WEEP FROM VALVE COVER AREA. ALSO INSPECTED TURBO AND CONFIRMED OIL ON EXHAUST TURBINE. THE TRUBO ITSELF HAS VERY LITTLE RADIAL OR AXIAL PLAY SO I SUSPECT IT WILL NEED THE UPDATED FEED LINE WITH CHECK VALVE (COMMON PROBLEM ON N20 AND N26 ENGINES). 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 IN...
