Absolutely 4/4 Boy - As an aircraft engineer, we use loc 243 regularly but usually around titanium threaded portions.(other products and specs are also available)

I know people have used it on these cooling kit bolts which has prevented the bolts from loosening, however, I feel it's really simply too easy with aluminium alloys, to strip threads where bolts either corrode or are bonded into their tapped holes, and these have to be regularly removed to gain any sort of access to the top of the engine.
The whole kit is a pretty poor design really. Whilst it's functional and prevents skip-fire, it's dead ugly, cheap, and vibrates around the top cowl causing rub damage to the rocker covers! (And that's before the bolts and spacers fall out.)
It's lucky no one has experienced anything dropping into the hole on the compensator(the old clunky one Morgan apparently according to my dealer, won't change) causing that to seize.
I'm currently (when I have time) trying to source some form of tab bolts or pre-drilled bolts.
Morgan Motors whilst having designed what is the most exciting drive one can experience, have truely rushed this beauty into production, hence all our issues.
Pete Larson must absolutely cringe sometimes at what they've done with the Liberty Ace.
