Yes, get an answer as to what it is, exactly and go from there. The key question is whether the vehicle shoudl go away or sink some money into it. For me that answer is How many miles do you get to a quart of oil. If more than 1500, fix the valve noise and keep on cruising. (the factory would no fix unless you used more than a quart in 600 miles, man I would not be happy with that....!)

Clacking from the valves is generally bad. Unless you are very mechanically inclined, you'll want to take it to a trust worthy mechanic. If it still runs well,it is likely just in need of a timing adjustment, which is not a big/expensive job. If its something else though, best to find out now, as a severe valve problem, if left un-treated, could do some serious damage to the engine.

What makes the transmission go bad

For an auto transmission........

1. Neglect of basic maintenance.

2. Normal wear and tear of internal components, ie high mileage.

3. Failure of electrical components attached to the transmission which are required for normal operation of the transmission.

4. Transmission abuse.

If you have over 130000 miles on a transmission you can expect problems.

2000 Chrysler 300M V6 with 150k miles started giving a clacking noise from the engine area after getting an oil change from Jiffy Lube. I was less than 2 miles from their shop when it started clackin

Sounds like your valve lifters. It's possible that they drained the oil and never refilled it. This does happen when they go on break or lunch half way through a job. They think they added the oil, but did not. Out you go, Mr. Clack-Clack.

Jeep liberty gas mileage

to increase gas mileage make sure you keep on top of tire air pressure you can also have your tires filled with nitrogen instead of air also a K&N air filter does wonders and is good for lifetime worth every penny. another smart move is to use a fuel system cleaner regularly Lucas makes great products for this try local parts store.

High gas usage

I was just listening to Car Talk on NPR (Click & Clack) talking about this exact thing in response to a callers complaint about poor mileage. Their advise was to: a. check the compression and b. check the thermostat.
With your 2001 being 7 years old your mileage is probably under 100,000 so your compression is probably OK. If you do check it the good compression should be about 150 PSI; if it's down around 100 PSI that could account for the poor mileage.
As for the thermostat if your engine temperature doesn't get un into the normal range fairly soon, the computer thinks the engine is cold and adjusts the choke accordingly which uses more gas

Hope this helps Good Luck Loringh

Catalytic converter

i replaced my cat with a high flow cat and flowmaster 40 series exhaust about 4 years ago now. good set up on my 2.2L 4cyl 5spd. sounds excellent. the only problem, since it is a high flow cat and free flowing exhaust, there is little if any back pressure, and so i really dont have that much torque anymore. it actually made my truck slower on the bottom end. not that the 2.2L is a speed demon. lol. you could probably get away with a test pipe that is still the same size as the stock pipe and it will sound gread. as far as gas mileage, i doubt it will do anything to help. my exhaust didnt help my gas mileage any. the only thing ive noticed that got me more mileage is replacing the stock air filter with a drop in K&N filter. i got about 5 more miles a gallon just by doing that. good luck.
