I inherited a 1999 Legacy Outback with 2.5L EJ25 engine that had blown a head gasket. The heads (and on DOHC the camshafts) have been removed. I do not know which cam cap goes where (other than knowing which is on left or right head and Intake or exhaust cam). That still leave two possibilities for each of the inner caps.
So here is the question. Is it critical that the caps are replaced in the same place they came off of?
