DISCUSSION:
There have been reported incidents of stuck oil pressure relief valve assemblies in the chain case cover. With a stuck oil pressure relief valve, the oil
pressure is not regulated as it is supposed to be, resulting in possible low oil pressure and engine damage due to oil starvation.
When a short engine is replaced, replace the chain case cover assembly if any of the following symptoms are present:
^
The vehicle exhibited low or no oil pressure at idle
^
There is metal debris in the oil pan upon removal from engine
^
Main or rod bearing(s) are spun
^
Crankshaft rod or main journals are scored
^
Intermittent oil light flashing off and on
The purpose of replacing the chain case cover is to prevent damage to a second engine due to a stuck oil pressure relief valve. Before the oil filter
adapter is reattached to the new short engine, verify that oil feed and return passages are clear of debris that may hinder oil flow or re-enter the oil
pressure relief valve on the new engine.
