Whats in Engine Re-Seal?
 

Is this what is normally meant by 'engine re-seal' for an 73 E with MFI:

Front main seal
Rear main seal
Cam seal (MFI)
Oil Pressure sender seal (crush washer)
Valve cover seals
MFI seals (side covers and control rack plug)
Cam cover gaskets
Sump cover seal
Oil Cooler seals

Thats about all I can think of w/o removing heads or opening case.

Or is engine re-seal a term for doing whatever is necessary to stop oil leaks, such as replacing oil return tubes, head gaskets, open case halves and re-seal.

I, personally, would include oil return tubes (if they are leaking), but not split the case, or the heads.

does anyone have experience with the crank sleeve that supposedly allows rear main to seal good in older engines. I guess the crank in older engines develops a groove where oil seal rubs it that cannot otherwise be sealed.

Does the sleeve work?

Also, if the rear main seal is part of 'engine re-seal' then trans input shaft seal should be part of it as well. At least on post 72 trans.
