Generally called dog tracking. Usually seen from wrecks not repaired correctly.

Essentially the rear end isn't angled correctly. Mind you on my truck I'm only talking .11 degrees on my truck. I'm not too worried.
I'm also just starting to research this stuff now.
Here's a simple graphic that explains thrust angle.
Ah okay. Yeah I've heard of dog tracking. I've seen cars like that before too. Looks funny lol.
..and that's half of the problem. Rings, old gaskets & other seals end up depending on the gap filling mileage carbon.
Using BG44k does get rid of the carbon but it doesn't add material to the engine that years of wear have taken away.
It's a gamble to do this kind of service to an engine that's never seen it before.
I know what your sayin, but as far as the gaskets, that's the way it use to be and not anymore. Gasketry has come along way since the good ole days.
Also, once you weight the differences pertaining an engine high on carbon vs clean, a dirty engine won't go as far or be as healthy getting there IMO.
I'm a firm believe in the "BG Service", - more so , the "Motorvac Service". Sort of proved that one as my engine has 319,000 miles and still doesn't use oil between changes.
It's just as you said here about snake oil ,-

I recall one user stating to research SeaFoam and you'll see how good it works lol. Well if he researched his self he would of concluded how much it doesn't do and how bad it could hurt the engine. That stuff has been catastrophic in the past...causing hydro-lock worst case!
I agree, maintenance neglected engines for long periods of time you can't come come back from, - there's nothing you do to get it back.
A high mileage well maintenance engine can go even further with the correct procedures. The BG and Motorvac Services keeps them clean in the right spots.
There's a couple proven products that work which one might refer to as snake oil.
1. For the crankcase. A product that keeps the internals clean and either works slowly or keeps it's clean depending upon condition. It's called Auto RX. If you use it once in awhile it really works.
2. The other is Techron injector cleaner. That actually does what it says it does as well.
Also remember, that crap doesn't just disappear. It has to go somewhere. Usually right into the Catalytic Converters. If someone already has high mileage CC's it can cause it to clog.
Besides what I've seen it do to other engines, It happen with my wife's 200k mile Honda Pilot.
The vehicle ran perfectly fine but AutoHoe sold her a bottle of Lucas fuel treatment with new wipers. I knew it was a bad idea but I put it in the tank anyway. (what could it hurt, right?) Three days later she was on the Highway, it started bogging down and it wouldn't go over 35mph. By the time I made it to her, it wouldn't even go 15mph.
The only thing I did to fix it was gut the cat. It previously never had a CEL and was a perfect college car for her. She drove it another 115k+ miles before trading it in.
Now granted it was a high mileage limited space CC but that's a perfect example of one of the unintended consequences of using these types of treatments.
Took the passenger exhaust manifold off today. After two days, I can say I've had enough. No studs, but bolts ... which means it was already changed. Exhaust manifold was completely cracks all around on Cylinder 1.. (front).
However since I cut the heads off the bolt as they were too rusty, I'm sort of stuck! I've got all of the bolt studs out without an issue but 1... Its about 1 inch of it sticking out to grab it and I've been soaking it in PB + 50/50 Acetone and ATF ... nothing.
Any suggestions? my vice grips are as tight as they are on there and I'm just pealing off stuff.

What did you do to your truck today?
