    Thumping in intake and ticking in engine

    It's a small knick in the valve head, nothing broken off. The material was magnetic, so who knows what it actually was before it got mashed. Valve recession on 6&8 crudely measured with a straight edge and feelers shows .016-.024 and head thickness measured at 3.744. Sent from my LG-H872...

    Thumping in intake and ticking in engine

    Look at the head pictures. All intact. I can't tell what it is, I'm going to check it with a magnet to see what it is, but I'd guess aluminum of some sort because it's smashed so flat. Sent from my LG-H872 using Tapatalk

    Thumping in intake and ticking in engine

    I can't tell what is in cyl 8. That's not the cyl that was showing a miss though, that's what's messing with me. There's no damage in the turbo, so whatever it was has to be stuck in the piston. I'll check it out better and try to get better pictures tomorrow. Sent from my LG-H872 using Tapatalk

    Thumping in intake and ticking in engine

    Well, I got it torn out finally. It's definitely NOT what we thought... Turns out the valves kissed the pistons. The lifters look fine, the cam looks good. I don't know what the metal flakes came from yet, so that's a little odd. Cylinder 6&8 both have valve marks. Cylinder 8 has massive...

    Thumping in intake and ticking in engine

    Last Friday I pulled it filter apart, and I found a little bit of metal in it. I'm currently trying to find a machine shop around me (central Ohio) that has done 6.0 work before. I'm basically planning on a stock rebuild with ARP studs and a stage 1 or 2 cam, nothing too crazy. Sent from my...

    Thumping in intake and ticking in engine

    I should probably also mention that the ticking came and went on the trip home, it's not like it did it all the time. There was no glitter in the oil when I changed it either, I'll pull the filter apart and look at it tomorrow. It's cold and late right now. I've been watching videos and it's...

    Thumping in intake and ticking in engine

    Hey guys, I've got an 06 F350. I recently had a missing issue that started on the way home from work, ran the cylinder contribution test and determined cyl 6 to be the issue. I drove it to work the next day (no other vehicle,) and on the way home it started a thumping noise in the intake and a...
