Hi Jon,

DON'T DO IT!!!!

PTFE is great if you use it regularly, but an older engine that has
not seen PTFE used will usually be full of sludge deposits. The PTFE
will loosen these deposits and they will end up back in the oil flow,
where they will block oil passages and foul the filter. PTFE
additives are not going to extend the life of your wife's westy engine.

Read this page for more info on PTFE before you add it to your engine:

Happy Trails,
