It almost sounded like a leaky donut gasket but when I opened the hood, it sounded more like a lifter or loose rocker. I found on the web there was an issue with the rockers loosing the needle bearings and being found in the oil pan. Is this possible? Anyone had any similar experience?

Just enough that when it warms up, it seals itself off. _____________________________ (in reply to RJaggers) Post #: 4 RE: Recent Ticking Sound?? - 6/12/2007 6:08:14 PM    alpha4wd   Posts: 16 Joined: 3/26/2007 Status: offline look at the rear bolt holding the exhaust manifold to the head, it's common for the head of the bolt to break off and cause a leak.
