    Given the fact you have a lot of experience with this engine, do you think it burned a valve? Or maybe bent one?

    2013 4.7 knocking, any help?

    Late update: Turns out it wasn’t manifold bolts. I had the broken ones replaced along with new gaskets and so on, and the ticking didn’t go away. So, i decided to experiment a little. Took the drivers valve cover off as the noise was louder there on Cyl 7. I then took off each rocker and I...

    Update: I got the manifold bolt on the truck fixed, and it still ticks, to no avail. Had another shop look at it and they also couldn’t pin point the issue down for me. I dropped the exhaust completely, made sure all fasteners etc were tight, noticed a loose heat shield on the passenger side...

    Whelp, i found the issue. This bolt right here is broken on the exhaust manifold. I took the shields off to look after replacing timing chains, tensioners, lifters, and rockers and the tick didn’t change. Also verified bottom end and cylinder/piston condition again and all of the above were in...

    Update Got tuck back from dealer. They pretty much told me that they can’t find the issue and screwed me for 200$. I will be tearing it down again tomorrow.

    I’m thinking it might be piston slap. Just makes me wonder why it would be okay the night before, and then when i start it up a few hours after running just fine, it starts to tick like this. I will be pulling the drivers head in a few days to see what’s up.

    I’m going to be pulling the heads soon. I know the cams are okay, it’s a SOHC design. I hear it more on the drivers side of the engine after using a stethoscope on it more in depth. Loudest from the intake manifold weirdly enough. I tested it again today by running it and pulling the plugs on...

    Small update: I might not be able to work on the truck soon, had a small work injury and crushed my hand. I checked for blow by today, just to see if there was any, and there was none. Just putting that out there.

    Alright. I’ll give it a try within these next few days then.

    Do you think that’s what could be causing this then? This engine was heavily neglected before i got it in 2020.

    Also, I have HP Tuners. Because of this i was able to record live data. Code for P0158 cleared itself, and as it warmed back up again it came right back on. It’s pulling 40° ignition advance and around 12-13% short term fuel trims on both banks. It doesn’t pick up long term fuel trims.

    I want to replace those, and I most likely will when I get paid next. Both drivers and passenger bank get quite loose when they’re cold. Not sure how normal that is.

    I can rule it out either tomorrow or the day after and let y'all know what happens, I plan on updating this post until i figure out what’s wrong. I need to listen to it crank warm and see if i still hear it if i listen very closely.

    I am also interested in how this turns out. The noise doesn’t go away at all until you let off the gas and coast. I’ve also noticed a fair lack of power too. Stays consistent and speeds up with engine RPM until the engine making enough sound from the exhaust to drown it out. Before I checked...

    Thank you, i appreciate it. I’m not completely sold on it being lifters either and like you said, Exhaust doesn’t make a ton of sense either, as it ticks even with the engine off. I am mostly basing it off the fact the noise does completely go away when it enters DFCO mode when coasting. I...

    Something exhaust would sound about right to me. I dropped the trans in April to replace the torque converter with a high stall one, and couldn’t get some of the flange bolts in right/tightened all the way down. The U clamp also broke a while ago that holds the muffler pipe to the y pipe.

    There is a tick in cold flood mode vs warm flood mode, yes. Ticking remains the same when the engine is running in dependent of temperature. It just slightly gets better when the engine is warmed up.

    Forgot to mention, when driving it, there was a pretty obvious lack of power and the truck seemed to sound a little weird. Set a P0158 code as well.
