Camshaft Cap Location for 2011-2020 GM 1.4L Engines

The AERA Technical Committee offers the following information for proper camshaft cap locations on 2009-2020 GM 1.4L engines. These LUJ and LUV engines are used by the Chevrolet and Buick divisions of GM. In the event you receive a cylinder head and none of the cap locations were documented before disassembly, refer to this bulletin. It is important that any cap that is removed be reinstalled in its original location. 
The caps are numbered from the factory, but those numbers may be hard to see before cleaning has occurred. See the image below to assist in locating the caps correctly.

Installing a Belt Drive

Upgrade for enhanced valvetrain/ignition stability

BY MIKE MAVRIGIAN

It’s no secret that high quality timing chain systems work extremely well and have proven their worth over decades of high performance street and race engine applications, and continue to be used with great success. However, the use of a belt drive can offer distinct advantages in terms of reduced friction and precise cam timing. The high-torque toothed belt absorbs crankshaft harmonics to prevent these harmonics from being transferred to the rest of the valvetrain, resulting in smoother and more stable cam and ignition timing.
A belt drive system can be installed “dry,” meaning that a base mounting plate is installed to the block, sealing off oil. The toothed cam gear, crank gear and belt are positioned on the outside of the mounting plate, operating in a dry condition with no need to expose the belt to lubricant. Depending on the race application, if running on paved surfaces where dirt is at a minimum, the belt and gears are exposed, making it easier to adjust cam timing.
