Breaking down and asking for help

6.9 and 7.3 passenger side exhausted manifolds are the same, right?

Bit the $65 bullet and bought a passenger side manifold. Only thing near there left I can replace lol.

Check the exhaust from the manifold to the up pipe, and I guess there's a joint in the up-pipe?

I know that when my crossover pipe cracked, it sounded similar...

Not in mine now!

Did you just use high nickel rod for the cast iron? I had envisioned taking the ats 088 turning housing off, blowing it up, putting a t3 turbine on, and welding a cast iron t3 flange on the exiting up pipe.

7.3 ats 088 same tick as you... let me know what you find I'm pretty sure mine isn't a small exhaust leak from passenger side manifold where up pipe connects to manifold, if you don't replace the stud on the manifold the up pipe will not seal right, like a 1/32 inch gap on it, sealed it with exhaust sealer stuff it stopped for a while then it came unsealed again. I haven't put the new stud in yet but I believe that to be my problem

That's a lot louder than the ticking I get. I'm running N/A and thought it might be an exhaust leak (might still be), but I can't get the downpipe flange nuts any tighter. Honestly, in your video, that sounds very similar to all the rocker noise my 300 used to have (rocker bolts working loose). I'm sure that's not the cause since you replaced all that and I'm assuming torqued everything down properly.

Its 55% nickle. Menards for the win!

Had to be really patient. Couldn't weld a bead or it would start to sound like glass slowly cracking. Had to do it one tack at a time and let it cool a bit- put a tack on the opposite side. Ill let you guys know if it goes to hell.
I dont have her runnin yet, maybe firday....

Well I got my fingers crossed it is just the manifold not sealing right or warped. I have a second manifold gasket so we will see. It's definitely not coming from the rocker arms, I've had those damn valve covers off so many times and double and triple checked my torque specs. I ran the truck with them off and with a stethoscope on each of them and nothing. Also ran my hand over the top of the while running and I sure couldn't fell any different among them.

I bought some similar rod off ebay because he will sell it by the pound or just 10 rods. Worked to fix a shift lever on my lathe and a broken casting on my power hacksaw. I just preheat with propane, weld perpendicular to the crack, higher amp pass parallel over the welds, peen it with my air chisel, and let it cool on a box of sand from my kids sand box. It holds up great. If I get a body lift on, I am going to weld that up pipe to the ats turbine.

That video was of the truck after I got home from work and it was still warm. If it's not the manifold it has got to be internal somewhere. It seems loud enough warmed up to be exhaust.

Any exhaust leak will show some black soot around it or the surrounding metal.

Thank you. Hahaha wish my truck was cleaner it would make it easier to spot! Plus the damn motor cross member is right in the way of looking at the underside of the header.

All my new manifold should be here next week so I won't get to replacing it until next weekend. I am going to use felpro gaskets and some stage 8 locking bolts after I torque it down. I'm also going to pull the cross over and up pipes and wrap and use some sealer on those when I put them back on. I'll report back if it goes away. If not, I am going to borrow one of those bore scope camera and pull the injector to see if I can see anything in the cylinder.

Just a follow up. Finally had time to work on my truck today. No change. I replaced the exhaust manifold with a new one, new gasket, and wrapped my crossover and up pipes. Ticking is still there. I was wrong on the symptoms though, now that it is warmer and I'm using my AC so the truck warms up, the ticking gets quieter when it's warmed up. So I'm completely at a loss as to what the cause of the tick is. Gotta be internal and either valve related or cracked piston/piston ring.

Did the passenger side manifold habe a stud with a sholder in it to bolt to the Y pipe?

Yeah it did. What effect does that have?
