Knocking/tapping noise coming from driver side exhaust manifold
2000 F350 with about 250k miles on it. There is a knocking tapping noise coming from the driver side exhaust manifold. No codes have been thrown. There was some black soot below the driver side exhaust manifold so we changed the up pipe gaskets on both sides but that didnt fix it. Put aftermarket exhaust manifold gaskets, ran the engine without the belt, and checked hot side of turbo for cracks. Everything checked out and the sound is still there. We are thinking warped exhaust ports on the head or maybe a damaged valve. I dont know if the owner does his own maintanence but the sticker on his window says he hasnt changed his oil in about 25000 miles.
