Observe the markings on the camshaft bearing caps. Each camshaft bearing cap is marked in order to identify its location. The markings have the following meanings:
* The arrow should point toward the front of the engine.
* The number indicates the position from the front of the engine.
* The "E" indicates the exhaust camshaft.
Install the right exhaust camshaft bearing caps according to the identifications marks.
