I have a set of PRW 1.6 at home and will check after work. I don't remember seeing that script but it's been a few months. I ran a tap through all of the threads and uses a pick to clear all the oil ports and then through them in the ultrasonic tank for a quick spin. Definitely check the oiling hole for debris.
I ordered a set of head studs and a harmonic balancer the first day of the sale and haven't heard/seen anything from them after the email reciept. Tried calling last week but couldn't get through. If they aren't on the porch when I get home I am going to have to start getting testy.
Doing all that, except cleaning them in the parts washer for new parts.
I also didn't get a tracking email, I made an account when I made my purchase, I was able get the tracking number in there.
