Mechanical Lifter Caution on 2001-2016 Nissan/Infiniti 3.5L Engines
The AERA Technical Committee offers the following information on a mechanical lifter caution for 2001-2016 Nissan/Infiniti 3.5L engines. This caution should be observed anytime the cylinder heads are being disassembled for repair. This engine uses unique mechanical lifters for its twelve intake and exhaust locations.
It is important to be careful and note locations of each while disassembling the cams and valves in these heads. When placed on a bench, it’s noticeable that the exhaust lifters are slightly taller than the intakes and have an N preceding their number. The exhaust lifters use Part #132317S(806) while the intakes are available with Part #132312Y(806) and have a U after their thickness number as shown in the photo below.
