I haven't heard about that one. What engine do you have?

A 2,2 liter fuel injected with dual cam shafts and I think the rocker arm lifters are self adjusting

I have the same Ecotec engine in my 2002 Grand Am. Check in at Ecotecforum.com to see if anyone has heard of it. I have my cam cover off twice a year to swap for the show season. I visually inspect my cams and timing chain. I'll have to make sure my bolts are snug in the future.
