Reply To: 1955 QD 16 Rod Knock/Piston Upgrade Question

[Jeff Barsch]

Donor engine and head gasket came in this weekend.   I got the case split and the and the pistons, rods and crank pulled and cleaned.  Everything is bagged up and ready to go.  Going to pull the QD-16 powerhead this week and get that cleaned up.  Rings coming today and the new lower crank bearing O-ring coming Wednesday.   In regards to that 0-ring, it appeared the QD-22 had sealer inside and outside on that, is it ok to use a small amount Permatex Aviation gasket maker for sealing that O-ring to the bearing and on the exterior to seal it to the case halves?  I plan to use Permatex anaerobic sealant for the block halves with no primer applied only to the cover half to avoid using too much.  I also plan to use Vaseline kept cool in the fridge to hold the crank needles in place. I am also confirming there are 29 crank needles per rod like in the photo from Marine Engine?
