I have a little bit of an odd noise after doing headers, I'm not totally sure if it is related to the header tubing since it doesn't sound like others I've heard. Although there aren't others around here with modified cars/trucks..
I'm going to try to detail everything I've done. It's a built forged 5.7 stock bore/stroke, mahle pistons and rings, molnar rods. I get quite a bit of piston slap but that's a more "hollow" tone I'd call it. 6.4 truck intake, the bolts were loose within 5000 or so miles. Long tube headers no cats, x pipe and dual single chamber mufflers. 392 car cam, non mds lifters, New valves, new mopar performance springs, 040 cometic head gaskets, custom routed the intake tubing. Used stock 5.7 injectors with spacers, 8 speed swapped as well.
Now the "fast ticking/rattle sound comes from the driver side exhaust pipe/header tubing only. Not the passenger side. I have a couple videos of it I will link those. I've run the stethoscope everywhere I can and can't pinpoint the location of the sound. Valve covers, block, heads, oil pan etc. Also did smoke test the exhaust front to back and can't find a leak, also make a stethoscope with copper tubing so I might hear some air escaping and nothing. I even ran it across the header Flanges and tubing. Cannot find a leak.
When driving with windows up I hear the ticking sound that's usually related to a flange or manifold bolt leak inside the truck. Can't find any problems with scan tool or datalogs with hp tuners. Fuel trims seem fine and wideband readings seem stable.
Around 2500-3000 rpm seems to be completely gone, but it could be that it's so loud I can't hear it anymore..
I hope I didn't miss anything here. Just curious if anyone else has had the same sound and is it ok or if there is a problem I should address?
