Now that Pikachu is spending a lot of time on the big roads, I have noticed a minor, but annoying, exhaust tick near the engine side of the system when the motor is under load. I did a little research last week and found a small exhaust shop with great Yelp reviews down the road about 11 miles. Met the owner there this morning around 9AM and he pulled out a little stethoscope to check it out. I have a leak at the first flange, just under the intake and exhaust manifolds. After looking at the three crusty and original nuts and bolts on the flange, he suggested that I soak it all in PB Blaster for a few days and slowly try to work them loose. So, that is my plan. I am hopeful that I can get them off without breaking them. I am guessing that there a 1 in 4 chance that I'm not drilling and grinding this sh*t when it's all said and done, but here we go anyway. My goal is to yank the three studs, put in a clean flange (maybe a Remflex?) gasket, and put it all back together with new hardware.
The way he put it: "I've seen nastier bolts free up just fine, and cleaner ones break right off, so who knows".
He also inspected my entire exhaust system, and said it all looked OEM original, solid, and definitely didn't need to be replaced (except possibly the muffler, which he noted was later aftermarket and that the Toyota exhaust had thick steel). I was surprised, as it's all covered in a crispy cake layer of Mississippi mud and rust. Truthfully, I originally showed up ready to leave the rig with him, anticipating a pretty new exhaust system from the manifold flange to the tail. He seemed to prefer that I do it, and I'm kinda glad looking back. But sometimes, it feel good just to let someone else do the work, despite the little time-sucking devil telling you how much you love working on these rigs. I even hit Google Images for proper exhaust routing to show him pre-tube bending, but I digress. This, like many other things, is right in line with Project Pikachu. Underneath the crud, this is a particularly clean 40.
The drive to this shop was its first 32 degree morning run since its early-2017 resurrection, and the old front heater kept up marginally/sorta well. I am pondering putting a rear heater in.

After that, I decided to hit a local air show for KFTW. As a pilot and aircraft owner, I don't make it to nearly as many of these as I should. Here is something fantastic: F16 and P51 Mustang slow flight together:

What a great country we live in. Good Saturday, y'all.
