Had to remove a cracked exhaust manifold on my granddaughters mustang and soaked the bolts down with the engine warm with a mixture of diesel fuel and marvel mystery oil about 50/50 and let it sit overnight and sprayed them again in the morning and about noon time loosened up the manifold like it was just put in. People need to have patience and not trying to rush things. There is a penetrating oil spray called Deep Creep and I think it’s made by CRC or some similar company and it’s basically kerosene and other chemicals and it’s not cheap but I feel that my concoction works just as well and it’s a hell of a lot cheaper. LOL keep wrenching 👍

Transmission works better but I use your same exact message pretty much. I understand where you're coming from but these guys in the shop so I don't have the time 12 hours to soak bolts down and things like that typically when they have a high-volume clientele

[@Blueshirt38]

@@JohnSmith-xx1lx Another thing that guys like jimdooner don't realize is confirmation bias. He has probably been using this mix of diesel/MMO for decades because some other old-timer told him it works, and every time he successfully completes a task in which the mix is involved, he confirms his existing bias that this mixture is what solved the issue. No telling whether or not it would have been any better or worse than WD-40 in that case. This is probably why each mechanic, or old guy with a garage full of wrenches has their own secret sauce for penetrating oils, and each one swears that theirs works, and that anything else simply isn't good enough.

I bought a used 2005 Yukon XL this this past summer. It had 197,000 miles on ot, so I actually bought a power train warranty to give me a piece of mind. My intentions are to keep it until frames rusts out. The body had some rust but was in good shape. I also had the ticking sound and figured it was an engine problem, but after seeing your video I found out I have 5 bolts broken on the exhaust manafold. I am waiting to see, if the warranty will cover the issue. If not, I am going to have all the bolts replaced and hope it fixes the loud ticking sound.

Now no ticking and no grinding sounds. I can actually here the engine purr and sounds great.

This happened to me except at the joint where the exhaust manifold meets the down pipe. The whole circumference of the pipe ripped off and it was a terrible noise.

I think he was referring to the stainless possibility galling the threads but that might be more of an issue with cast iron heads more so than aluminum heads. I have never seen antiseize cause a bolt to prematurely loosen. Just my experience over the years. And the bolt broke why? Was it just rusted out or was it the difference in expansion rate between the aluminum head and cast iron manifold?

[@tyyoder8783]

Could an exhaust leak in that location also cause a random misfire? My vehicle is a 2002 Silverado 6.0 gas engine. Looks like three (2 on one side and one on the other) exhaust bolts are broken.
