Hi all ;  Traded for an unknown used engine a few years ago , just to have on hand.Finally got around to needing it this spring... and what do you know.. rod knock on start up and audible knock at certain rpms.  So I am going to split the case and see just how bad it is, before it self destructs . I.m looking for recommendations to buy on bearing type , ring type , should the pistons be replaced at the same time ? What is commonly found needing replaced when opening this motor up ? Should the crank be turned no matter what or is it possible to just put in new bearings ?   The last subi case I split was an EA 71 , never gone deeper than the heads on a EJ motor.

Turning the crank would make the job easier, then you can get one size bearing as they are not the same from the factory.(This adds to cost)

Subaru , King or ACL for bearings, your choice. NPR for rings, keep the pistons. Engine gaskets from Fel Pro and the odd O rings from Subaru.

 

O.

If you get ACL bearings, do NOT get the ones in the blue/white box.  They used to be made in Tasmania and were great quality.  Now that style is made in China and they're only 2 metal bearings without any copper.  Michigan Clevite also repackages NDC bearings which are OEM.  The ends of the bearings are clearly stamped NDC.

 

Keep the pistons in the same cylinders from which they came.
