Ah crap, such a small pain in the backside.

I have a tick coming from the right side header and once I tracked it down it's coming from between the 4 tubes right where they merge into the collector.
Now I'm going to have to pull that header down to where I can get to it and cut the collector off so I can get to that area inside with the mig, and then weld the collector back on.

(Unless one of you guys have a better solution, which would be nice.)

I wish I could think of something I could swab the inside with to seal it but I can't think of anything that would hold up.

It's just a light tick that you can hear that sounds like a lifter, and I only hear it at light throttle cruise echoing off of curbs I am right next to.
