hey guys took this engine appart today and just between all the messed up stuff the engine had which i really dont want to get into detail right now but anyway. someone had definetly opened this engine before and to make the story short there were no gaskets in the engine i guess someone tried to save a few bucks and not buy a master rebuild kit. only silicone on the whole engine and what killed the engine was a rear rotor bearing failure causing the side of the rotor to smash into the rear iron and smashing the 3 side seals into the rotor on that side and of course no compression on that side. one of the weird things i found was that the front weight only had 1 hole dead center on the top of it. i ve done a couple of engines before and all of them have a weight with 2 holes on top. now here comes my question. is this the right weight for this car or is this for a diferent series engine? Im just asking because obviously whoever opened this engine before had no clue on what he was doing. and it wouldnt surprise me that that weight was from another series and unbalanced the engine causing the bearing to give up. also could it be from an N/A i've never disasembled an N/A engine so i wouldnt know.

the engine was pulled out of a 87 TII.

Front counterweights are the same across n/a turbo and very slightly different across series.
