My truck just recently started to knock well I wouldnt really say a knock its not detonating or anything, Im pretty sure its my lifters making noise, it only happens on cold starts and goes away after about 30 seconds of running if I turn it on,on a cold morning and dont give it gas,just let it idle for a little I dont hear them making noise and then its good to go, but if i turn it on, on a cold morning and dont let it warm up a few seconds then i hear it making noise now this is my question could it be a lifter problem were I need to replace all the lifters as a reliable source told me that this is common on those engines and all the lifters would need to be replaced OR I also looked up on ALL DATA a TSB that says the seal between the oil pump and the oil pump pickup screen gets cut on these engines which causes oil aeration and thus a lifter knocking sound only on cold starts? How can I confirm which one of these is the problem if any of these is the problem?
