Question about 1994 Jeep Grand Cherokee
I get an intermittent loud metallic knocking from the engine but difficult to determine where from. Stops when in 'park' and sometimes when you take foot off accelerator and may not happen for 5 miles. Sometimesit is more persitent - any ideas?

Its a bad rod bearing. I worked at a jeep dealer for a few years and its common. Not that jeep will say there is a problem. However I wil tell you that the engine can last a day or a year makin that noise mine did it for 4 years lol. I put lucas engine oil treatment in it too....Seemed to help. Also know someone who used castrol oil but a thin grade like 5w20. the thinner oil is able to get between the beaing and the rod better thus quiting the noise...
