Hey i just traded my xterra for a 2001 xj. Its got 360000 kms and runs great. Oil pressure is good. When i first start it in the morning or after work theres a bad tap or knock in the motor. I cant tell if its in the crank or the valves. It doesnt get better or worse if you hit the gas, and seems to go away or get quiet after its warmed up. I have to wait until the morning to listen to it better, as its still warm now. Any ideas? Oil looks clean, but im gonna pull the valve cover and see if theres any sludge. I would sooner roll some bearings in it now before the snow hits. Any help would be great.
Also the jeep always runs about half on the temp gauge. Is this normal operating temp on these?
