So I am just curious if anyone else has this same noise... When I start up my car in the morning for the first time (about 50 percent of the time this happens) I have some noise that I would have describe as "Lifter" noise. Obviously there are no lifters to pump and I really am not that familar with OHC so I am just curious if this is normal or not? I did a search on this site and I came accross something with the Cobra's DOHC and timing chain noise at start up... As a side note this noise is present with motorcraft filters and I just switched to a K&N to see if that alleviated the problem but it didnt... I have been using mobil 1 5w-30... Like I said it sounds to me like a Top End Half Speed noise, not a lower end noise... Car has 50K miles on it. Any thoughts?
