Camshaft Removal and Installation Caution for 2011-2020 Jeep 3.2 & 3.6L Engines 

The AERA Technical Committee offers the following camshaft removal and installation caution for 2011-2020 Jeep 3.2 & 3.6L engines. This caution should be referenced before cylinder head work begins such as removing the valve cover. 
These engines use a separate camshaft for intake and exhaust valves and each camshaft has a pressed on magnetic timing wheel that is magnetically encoded. There are two camshaft position (CMP) sensors located between the timing wheels as shown in Figure 1.

Oil Pump Inspection for 2007-2011 Jeep 3.8L Engines

The AERA Technical Committee offers the following information for inspection of oil pumps for 2007-2011 Jeep 3.8L engines. This information should be considered anytime the front cover or oil pump have been removed. 
The oil pump for this engine is in the timing cover and is driven by the crankshaft. While some parts for repair remain available for repair from the manufacturer, expense and availability of the timing cover deters complete component replacement.

Giving a Coyote another life…
no help from ACME

BY CHUCK LYNCH WITH RUSS HAYES AND COTEY NOBLE

As soon as the Coyote hit the street in Mustangs, there were performance shops conspiring how to build more cubes, how to make more power, how to scratch that itch. This article is not intended to dispute, question or modify what is already being done in the performance market; what it does intend to address is the need for servicing the stock replacement market.
As a tech on the phone line, I can tell you that we are more aware of the cylinder head short comings. There were some early valve and seat compatibility concerns that seem to have
been addressed by some material changes. There are some differences in valve installed heights, roller follower failures but we fortunately are not hearing of the VVT issues that the Triton was infamous for.
The Ford 5.0-liter V8 has now been in service long enough that the remanufacturing of that engine for exchange is being looked at with more critique. I have gained some insight on some of the challenges of giving this engine new life from Russ Hayes, a longtime friend in the industry and personally. Russ is currently a Product Engineer at Jasper Engines and Transmissions.
