Glen, to let you in on a little secret, the previous owner and his maintenance? What maintenance? There was none. The car sat for 10 years.... But its intrinsically coming back, slowly but surely. Some things were done, but not much... But considering what I paid, I'm still very much in the black. Thanks for the advice... BTW, is there a way for myself to visually inspect the chain guides without taking the whole valve cover off?
