Thanks for that information. First I've heard of issues on the PRW ones. I'll be sure to verify my oil supply and keep an eye on them.
Don't want to divert the original thread throwing guesses at what caused it for you.
I agree looks like when I feel better I better remove mine and look them over. I have open headers on my 91 dakota, so I dont think I could hear any valve train noise. But the last time I checked the valve lash everything was good.
