Jeep Grand Cherokee Laredo. I have been told the ticking noise my engine is making is a stuck lifter and by substituting a half quart of transmission fluid for a half quart of oil will solve the problem. Is this ok to do? Or is there a better way

If I understand your situation, you are saying the engine was run with one quart and you added 2 more quarts of oil. Now you have 3 quarts which is less than what it takes to make it full. On some engines it takes 5 quarts of oil. You will have to check the dipstick to see where you are now compared to the full mark.
If it is still less than full, it may cause some noise, but depending on how long you ran it with the oil low, how hot it got and other unknowns, you may have a serious problem. Try adding oil to the fill mark and pray that after you run it awhile the noise will go away. The noise may be the lifters trying to work with little or no pressure. It is possible that after the oil top off and a bit of driving they may pressure up and start working again.
Most time a ticking noise is caused by a valve lifter malfunction or a worn pivot on a rocker arm. if the noise appears to be coming from the valve cover (inside) that's usually where the problem is. Depending upon which engine you have the repair procedure will vary. (consult a haynes or chilton manual) Before taking anything apart though many times a lifter noise will respond to a good engine additive like marvel oil or lucas engine conditioner. Neither one will harm the engine and it may quiet it down for you! If you think my answer helped, please rate it. If you have another question or did not understand the answer, just ask.
more than likely you will need new lifters but i have gotten away with substituting 1 quart of atf for one quart of oil on an oil change that seems to work good and make sure you don't use any thick oil treatments and are running 5w30w oil..
Ticking can come from so many places I could write all day... Use a screwdriver or a long extension as a stethoscope and try to isolate the source. Best guess I can make without seeing/hearing it is either you cracked an exhaust manifold or a valve lifter is sticking (only a guess) If it's a lifter, you can add a quart of marvel oil and usually it will quiet down.
i was having that problem with my 4.7 2000 laredo. had no idea what it was. after about a week and a half of my jeep sounding like a diesel i was going 75 on the freeway and my engine started to rattle and shake violently and then shut off and left me stuck on the freeway. took it to a shop and they told me i had bent a valve because my timing chain had jumped. motor is now beyond repairable. new motor is going to run me $2300 plus $1700 in labor (assuming nothing else needs replacing) highly recommend taking it into a shop asap
First, nothing you have done has anything to do with valve tappet noise. What is your oil pressure? Have you positively identified the noise as a lifter (tappet), OR COULD IT BE AN ENGINE BERARING OR WRISTPIN? Other than tearing it down and replacing lifters, rockers or pushrods or possibly even the cam, if oil pressure is good, change the oil and put a quart of Marvel oil in there. If that does not clear it up in a few days, you will have to go inside the engine. You likely have over 160k on that engine...consider using a replacement. Get an older tech to listen to it...it takes years to be able to differentiate between different component noises with any accuracy. Personally, without hearing it myself, I'm betting it's a rod knock.
