01 Grand Cherokee 4.0 L6 95,xxx Miles.
Lately I've noticed my jeep has been making a engine noise does not seem to be coming from the bottom end, quieter than a bad piston skirt. Oil pressure is good etc just did a fresh oil change yesterday, so my question is what could it be? I am newer to jeeps but not mechanics. I know naturally these are noisy engines, the jeep has always been well maintained and serviced on time. Also on a side note it started once the temperature here dropped been in the 20's lately. It appears to go away once completely warmed up when I did my oil change nothing came out with the oil and nothing seem to be blocking oil from flowing out. I am in need of a tune up and a downstream O2 sensor, randomly throw a misfire code occasionally. Any input is welcomed thanks.
