Engine Oil Leak On
1995 Subaru 1.8 & 2.2L Engines
The AERA Technical Committee offers the following information concerning an engine oil leak on 1995 Subaru 1.8 & 2.2L engines. Leaking oil has been reported between the engine oil pump housing and the cylinder block sealing surfaces.
The cause of this leak has been traced back to an inadequate size oil pump return hole. The return hole should be .235 (6 mm) in diameter. It is permissible to enlarge the hole size to the correct dimensions by using an appropriate size drill bit and drilling.
Applying grease to the end of the drill before drilling will minimize the chips created. Using the tool, carefully enlarge the hole to .235 (6mm). Then, clean out the hole for any extra shavings that may be left behind. Upon completion of
this procedure, carefully reinstall the oil pump.
