Description Engine swaps are popular amongst the Subaru community. However, most owners are unaware that Subaru uses different rear timing covers for the manual transmission (MT) vehicles than they do for the automatic transmission vehicles (AT). The difference is this, the MT engines include 3 additional timing belt guides, whereas the AT engines do not. These additional guides keep the timing belt from skipping during hard MT shifts. Keep this in mind when installing a AT engine into a MT chassis since these engines have zero tolerance valve trains (skipped teeth can bend valves). The solution, remove the entire timing assembly and install the correct MT rear timing covers along with the belt guides. Note, the rear timing covers arrives bare, as shown in the image.
