Hi Cam,
I tried to figure out which engines had not only aluminum blocks but non-ferrous cylinder liners - but I had to give up:
- What is the metal for the E39 short block, cylinder liners, & camshaft head (1)

Why, specifically, is the OP better off with replacing the engine if he has the aluminum short block?
  • Is it because the labor is much more to 'fix' the aluminum block engines than to simply replace them?
  • Or is it because the chance of 'fixing' the aluminum block engines is too low (due to heat-related cracks, bolts pulled out, warping, etc.)
