I first noticed by lower two were loose about 3 months ago when I was changing oil.

Yes, they had lock washers on them.
Yes, I torqued them to specs the first time.
I did not use loctite the first time per the plans.

After adding blue loctite, and re-torquing to 26-30 ft pounds I have flow 50 or so hours with no further problems. I check them every oil change or 25 hours, and whenever I have the lower cowl off. Since they were re-installed they have been fine.

I highly suggest adding "witness marks" with a black marker or torque seal so there is a visual reference on the heads of the cap screws.
