Ticking Noise Under Load

[kingpickle]

About a month ago, my mountaineer began making a ticking noise. I dont hear it while in park (idle or reving). When I put it in drive and accelerate, that's when I hear it. The rate of the ticks get faster the more I accelerate. Release the gas while moving and the noise goes away. It's a 2006 6 cyl with 130k . Other than that noise it feels like it's running fine. I've had it 1 year and have done regular oil changes under 3k miles, new oem plugs, wires, fuel filter. The only different thing i had done to it before the noise began was switch to synthetic oil a month prior.

My regular mechanic says it sounds like a problem with fuel/air mixture but no codes are popping up. Any suggestions?

BTW: When going through tunnels the noise seems to be way louder on the passenger side

Thanks.

exhaust leak

Sure was. Both exhaust manifold gaskets redone. Sound is gone. Ran me $450 bucks (stubborn bolt broke inside). Thanks for the tip.

Any time. Happy to hear it was such a minor issue.
