98 ZJ 5.2L clicking Engine noise need help please
I just picked up a 98 ZJ with a 5.2L V8 for real cheap, and it has a heavy clicking noise coming from the engine on the passenger side. The noise only occurs when the engine is at normal operating temperature, and it does not do it at idle, it only makes the noise when the engine is revved up to around 2200 then it will make the noise continuously. The frequency of the clicking also increases as the RPM of the engine increases.
The jeep still drives fine, down the highway at 60 mph with no problems with hesitation, or loss of power. The previous owner had always used penzoil, which i have always had problems with, but thought at 91,000 miles major engine trouble is not to likely. My first thoughts were sticky valves or a lifter that has a problem. If anybody needs more information, i will do my best, and any help will be appreciated.
