Hi,
Have a 826 with 358DT ( there isn't any turbo)out of a 1420 IH combine. It was put in about 7 years ago.We overhauled it 3 years ago almost to the day because of water in oil and now it happens again. Changed oil and find anti-freeze in it. Left it sit over night there was a little bit in there the next morning. With oil pan off it was dripping off of number 3 sleeve.Put about 12 p.s.i. in cooling system and it leaked from # 3456 sleeves.There was 2 different sizes of o-rings in the kit, one was .187 thickness the other was .197 thickness.We used the .187 because of the serial #18488.To used the .197 I thought it might be to tight on the sleeves.Pulled it apart every thing looked good,there was a mark around the sleeves where the o-ring was,but it was smooth.


THANK YOU,
Marlin
 
If there is any ware where the O/Rings set then they are not sealing and your sleeve is moving when the engine is running .If you can feel where the O/Rings set then it is time for a lower counter bore repair i do not care how smooth they are .
