this is kinda funny that i read this 2night.
My engine sounded fine, untill about 4k miles. Then i got this insane slap/tick sound comming from around my exhaust manafold.....
cept you cannot hear mine when my engine is cold, only once it warms up.
I took it to the dealership and demanded it fixed( i work for there parent company). At first they just tightned my exhaust manf and said hey its good...i went back there and sat down with the tech and told him no. I pleeded with him to just take off the valve train cover and check the clearences...if it waznt in there i would pay him for the time...he wouldnt...kept saying it waz normal...
i finally went to the svc manger, and told him to take off my ****** valve train cover, he himself did, and BOOM!!! imediatly noticed some rubbing spots....cant check clearences untill 2morrow, (engine has to cool) but looks back because of those spots.
btw, this is the 3RD time i have taken it in.
