Ok bear with me on this, I have never ran into this before. I bought this Grand Marquis about 2 months ago, drove it for a week motor sounds great. Checked the oil it was full but was very dirty so I changed the oil and filter and every since then the lifters (sounds like to me) are making a terrible noise, it sounds like a Diesel. Now here is the kicker after I changed the oil and filter other than the lifters making noise the oil shows a quart over full so a week later I changed oil and filter again and the lifter noise is louder and still shows a quatr over full, I checked the oil i drained the first time and it was 5 quarts and of course thats how many I put back in both times. So does it seem strange that after I changed the oil for the first time the lifters knock and it shows a quart over full? any Ideas on why this happened and how do I fix the problem. Been told several times lifters are not pumping up, but I dont know. FYI car runs great, no stalls, starts right up, no hesitations or anything. What do you think.
