Exhaust Leak?????
Hey I didn’t create this just because missed you guys, lol. I hooked up my trailer to my 85 Ford F350 and went and picked up 2 tons of hay. I was almost home and out of know where it sounds like an exhaust leak…I’ve heard one before. It gets louder as I accelerate. What is the first thing I should do to diagnose? Also, is this something I can tackle myself? Can I occasionally drive the truck in this condition until the weather warms up? It’s great to be back 😵💫😵💫
Thank You

Locate the leak. Have somebody sit in the truck and power brake it and listen for the source. Check your manifolds to see if they're cracked or whether it's just the gasket at the head or where the exhaust pipe connects. It could also be the pipe that goes from the back of one head to the other for your EGR. Or maybe the exhaust pipe itself is cracked and needs welding or replaced. If it's the manifold gasket, you can ride with that for awhile, although it's giving your O2 sensor a lean reading. The pipe on the back of the head should be replaced or plugged if it's faulty

Its not really good to drive with an exh leak and even more so in winter with the windows rolled up as CO2 in the cab has no way to get out.
You can take a shop vacuum and switch it so it blows out and hook it to the tail pipe and turn it on high and check the system to see where it is blowing out of.

Evidence presentation 😵💫
Okay I haven’t tackled this job yet because I’ve been out hunting. This morning I started my truck so I could narrow down where the ticking noise is coming from. Man it just seems to come from no specific spot. I’ll take my wife out there in a few to see if she can help narrow it down. Although, as I revved the engine the ticking would speed up. If I pushed harder on the gas causing the engine to run higher at a certain point the ticking would go away…I’m confused. Is there an explanation for this? Also, any suggestions?

When the engine is dead cold, start it up and then quickly run your hand around the exhaust manifolds feeling for air puffing out. You can do this for a few seconds till the engine gets hot. If you can't find it, stop it and let it cool off again and then do it again where you didn't get to the first time.
You can also take a very good flashlight and carefully inspect around the exhaust manifolds, and where they connect to the y-pipe. If you see any black, that is where it's leaking. You can then verify this with the hand trick on a cold start-up.

Okay here’s an update. My neighbor, Harry, did exactly what Dave (Franklin) recommended and we couldn’t find an obvious leak…darn it! With the engine running I put a piece of cardboard over the end of the exhaust and the ticking changed pitch dramatically and sorta sounded to speed up…hard to be sure about that part. But, plugging the exhaust changed things for sure. We both believe the ticking is definately an exhaust leak. On the drivers side manifold there is a missing bolt, but I noticed that long before the leak. I’m wondering if there a broke off bolt and it’s simply held tight…who knows. Here’s another question. Should I just pull the exhaust pipes from the manifold and then pull both manifolds, clean them up, install new gaskets and put it all back together? I don’t mind buying new exhaust manifolds if you guys think it’s best…just let me know. Let me know what step I should take next…
ps: my rear brakes work incredible…again thank you.

Probably the first thing is to find your leak. A missing manifold bolt is a good place to look closer at. Feeling around cold and you can't find it? Maybe try a short piece of hose as a stethoscope to your ear to help zero in?

Soapy water might help right at first before it's hot. And air or smoke through the tail pipe can help.
