Interesting article in this month'* HRM about recent cam failures in traditional engines due to the use of cheap offshore flat-tappet lifters and reduction of certain additives in modern engine oils.

Anybody have this problem? come to think of it, do 3800 Series IIs have flat tappet or roller lifters?

Rollers.

Been rollers for long before Series 2.

I couldn't remember from when i did my car about 18 months ago.

I was a little worried about the 455 in my convertible, but it has Crane lifters and not much over stock valve spring pressures.

thanks to youse guys.
