I thought the comb looked dodgy from the start.
I just use a bent coat hanger wire to manipulate the pushrods into position and don't seem to have any trouble.
Using Peramatex blue (while giving a oil tight seal) I always worry that, when removing it, that swarf may end up somewhere in the guts that may cause trouble.
Should I just use a gasket and put up with a bit of weep?
