Hey guys I've got a 01 GT with the 4.6. I've had it since dec and have put about 15,000 miles on it since then. It had a prochamber on it when I got it, but I wanted it to be legal so I got a hold of the original exhaust, but the dealer made me give back the prochamber in exchange for the stock h-pipe. It still has flowmaster mufflers on it though. Now the problem is that it makes a tick whenever it's running. I work at a lube shop and I've pulled it in and whenever its in the bay and the pit is below it, I can't hear it, but when I go downstairs and listen its much louder then it is from the top. I also can't really hear it that well when I have the hood open, but when its shut and there isn't a big hole underneath it I can hear it. It's not really loud enough to hear inside of the car unless I'm next to something for it to echo off of.
I've taken it to a mechanic and he looked at it and revved it acouple of times and said there is nothing wrong with it. But someone else told me to add an additive to the oil so I put a quart of that Lucas oil into it and it didn't help. Then some other people have told me that the lifters could be dirty or not getting oil. I'm not sure what it could be, could it hopefully be just a simple exhaust leak?
And I've been told by some the cars previous owners friends that its had a new motor put in it, I'm the 3rd and I guess the 1st beat the hell out of it. I changed the oil after I bought it and a cigarette bud came out of the pan, its' also missing a clip that clips the dipstick to the valve cover.
What do you guys think it is or what I should do?
