Hey guys, Just a qik follow up,I went into my dealer over the weekend & I made him start a XR6T to see if I could point out the noise if it happened,he started it up & it idled for about 2mins then a slight sound started but not as loud as mine makes at home.I said to the dealer "there's the sound it's like that but mines a bit louder & rattles a bit more". I forgot to mention to you guys in my original post that my XR6T is a 6 speed manual but the XR6T he started was an auto transmission as that's all he had in the yard,after hearing the sound he said to me "Your car is a manual hey,then it sounds like the thrust bearing spiggett,it's normal" or something along those lines,he then suggested when I get home to warm up my car until the sound starts & then try pressing the clutch to the floor & he said the sound will go away whilst the clutch is to the floor & he was spot on. Guy's I'm not a guru by any means when it comes to engines & stuff but he said that it is the thrust bearing spiggett engaging or disengaging something like that,can anyone give me more user friendly explanation.
