Also take a close look at the bolt that hold the bell housing to the transmisison case. They go thru into the oil in the transmission and will leak. When rebuilding a transmission we always use copper washers with out the lock washers and thread sealer.

If you pull your gearbox, also check the seal on the gearbox input shaft. It goes to the same place engine oil does.

  I know there have been discussions on oil leak from the rear of the engine.  However, in reading through the archives I found this inquiry:


  When I rebuilt my AH3000 engine, I fitted an after market rear seal.  

  Unfortunately after I buttoned everything up and started the engine I 

  discovered a troublesome oil leak.  So out came the gearbox, the clutch 

  flywheel and the engine back plate.  Upon careful examination of the 

  rear seal, I can find absolutely no leak.  However, there is oil weeping 

  from the bearing cap that holds the cam in place.


  Is this normal?  Can the bearing  be replaced with the engine in the car?

  There were no responses to the inquiry.  So can the cap that holds the cam in place be removed while the engine is in the car. Could the cap be sealed from the outside with todays technology of sealants? Also, according to the external engine diagrams in the moss catalog it does not show the back of the engine or the cap.  


  Looking for answers to my continued oil leak problems.
