hello
im new to the forum. i recentally bought a csvt i have to admit im not a ford guy but i allways thought they where cool so i broke down and bought one. i am regreting it. it ran fine for about 1500 mile's know i have a ticking sound. the tick come's in at about 2000 rpms through the band. the sound gets worse as the car heats up. the tick first occured while i was racing it:(. this is what i know so far. i brought it to a local shop and he does not know much about the engine he told me right off the start. so i took it to a svt dealer in the area and there not much more help. they have the top off and said there is so much sludge in the engine they can not diagnoise it wtf. the sound is from the top end. should i just get the car back and run oil treatment through it to get ride of the sludge(maybe a stuck valve or lifter) or should i let them rack the bill into the multithousands to fix it.

thanks for your help
