Hello everyone, I’m looking for a little help identifying the source of this strange noise my truck is making. Oddly enough I noticed it for the first time after breaking in my new oem style camshaft and lifters. Break-in went well and I noticed the noise when I was done setting the ignition timing. I can really only hear it in the cab. I’ve gotten under the truck and also listened in the engine bay but can’t really pickup on the location of the noise. I really hope it’s nothing mechanical related. It sounds almost like something is vibrating or coming into contact with something else. Noise increases with engine speed and seems to go away for split seconds when I hit bumps on the road. I was thinking of pulling the transmission inspection cover to make sure it’s not coming from there but when I realized I need to drop the exhaust for that I thought I’d check here first. I’ve swapped to another distributor I had to eliminate that. Thank you for any suggestions!
