Has anyone rectified the 11/12 coyote knock or “tap” in the F150s without swapping the entire engine. My 12 has had a serious tapping for about 10k miles now. Everyone is saying it’s the #4 cylinder distortion that’s an issue, but another Ford tech said it sounded like top end. I just put in brand new oem chains, guides, tensioners, phasers and an oil pump about 2000 miles ago. No change. Trying to decide if I should just install the 3k mile short block I have for it or try to do the lash adjusters and rockers before hand. If not it’s getting the new short block with the mustang Intake cams, and a boss 302 plenum. Already has ARH long tubes on it. Anyone run into this issue? Thanks
