Dear Roger,
You've got me worried now. I've just bought a MOCAL adaptor to put on my
2.5PI. This has arrived with a choice of inner O rings and a piece of
plasticene to check the fit.
May I ask why you were tightening yours so hard? Was it to make the inner or
the outer ring seal?
I note the manual says the stock filter bolt should be tightened to
11-14lb/ft. IMHO, you must have been tightening yours a lot harder, unless
the earlier blocks had very little metal around the boss mentioned.
Can you recall how old your MOCAL unit was? These are sold in the UK and
I've seen them fitted and working. Could it be that they have sussed out the
depth problem and altered the machining profile accordingly.
Looking forward to your opinion, BEFORE I fit my adaptor.
Dave Hill
