sounds like it would play on your mind if you didn't do it... like you say, easier to do at this moment

Just to stick my oar in......Loctite bottles are porous .....its the lack of air that makes it go off......

The old loctite was in a bottle about 4 inchs high and has like a bellows for squeezing the orange goo out.
Gaz.
Gaz, as you've stated that your squish is between 1.5 -1.8mm, I'd say do it again and look for a squish of no less than 1.2mm. You may need a thinner base gasket or head gasket to get the right squish and only a thin smear of the Loctite. Don't forget, you'll need to re-torque your head again in a few hundred miles, anyway.
