Any auto mechanics out there

Hey all. I was replacing the oil pressure sensor on my Infiniti due to a leak. Putting it back in I over tightened it and caused a nasty crack. Also, it looks like I stripped the threads. Will this need to go to a shop or might this be fixed with JB Weld? Feeling pretty stupid right now.

The problem with trying to use JB weld, is that it has to be totally clean. The slightest amount of oil or residue left, will create a leak.
You would need it very clean. Spraying it real well with carb cleaner and then spraying it will brake cleaner and letting it dry, the check for any sign of oil. If there is still signs of oil, repeat until no oil is visible.
Coat a fitting, the same thread as the oil pressure sending unit thread with grease, then coat it with JB weld, careful not to get it close to the end threads, screw it in the hole, then coat the outer section if the port with JB weld. Once the JB weld is set up, gently remove the temporary fitting . Let the JB weld set up for at least 3 hours.
Then you have to be real careful installing the oil pressure sensor.
To be honest, it is a hail Mary move.
There is a strong chance it will leak.
Even the best mechanics have done that at least once.
Is the oil pressure an o-ring fitting or pipe fitting?
If it is o-ring, forget everything I said and find a really, really good shop.
And even a great shop may say they would have to do a lot of tear down to repair it correctly.

If you can get that bushing out and replace it, that may give you a better chance of success.

JB Weld is holding. I get a drip of oil about every 5 minutes from the treads, not the cracks on the sides. Truthfully the jury is still out but hopes are very high.
But there is also a danger of over tightening and popping the crack back open.

Locktite pipe sealer or Teflon tape is usually the better way to go, for future reference.

Brand new car under 3400 miles dealer states a red granular substance in tank has caused a blockage and the whole fuel system needs replacing. They claim it was placed in tank after purchase but I'm wondering if it could've been in there prior to...

It'll be fine once the swelling goes down.
The kicker is warranty won't cover saying it's an insurance claim and insurance isn't sure they will cover either...WTH
Could it be rust?
Get a locking fuel cap

Sugar won't mix with gasoline, which is why it creates such problems.
If it was vandalism and you have full coverage, it should be covered.
Have they identified the substance?
The dealer will do everything they can to not warranty it. Contact your insurance and see what they say.
If you have USAA or Liberty Insurance, you are probably SOL.
They don't like to cover anything.
Not knowing what the substance is, it's hard to say, but sugar can remain in the system for a long time on the bottom if the tank and may take a while to cause problems in the fuel system.
It won'be noticeable until it starts plugging injectors, filters or other parts.
Depending on quantity, it may take weeks or months for it to do damage.

Zero signs of vandalism but to be honest I'm okay if that's how its written up to repair it.
It's beyond me why they care, it's under factory warranty (less than 2 months old, bought with 20 miles on it. Everything in my gut is saying it's been in that tank prior to me buying it.) Current Insurance is giving push back but sounds like I made a good decision to hold off switching to USAA until the end of current policy, almost made the jump last month 😂
Thanks for the feedback, now I have a little knowledge under my belt to argue my case...
As was said, rust, tank sealer and several other things can cause similar problems and would be related to the manufacture of the vehicle.

Normally, the OEM fuel filter woukd usually pick that stuff up, but not always. And generally, a fuel filter will be 10 microns, which sounds small, but 3 micron particles, can foul an injector.
I would agree that the whole system seems overkill.
More than likely, the pump has failed. What, if anything after that has failed would be relatively difficult to determine.
Each component would have to be tested electrically, then with fuek pressure and if the pump has failed, the pump has to be working to condemn, the remainder of the fuel system.
Replacing all of the fuel system is what we call a shotgun repair. If you throw enough parts at it, it's bound to fix it.
Not fond of places that do that.

I did get a laugh when he mentioned another lady had women at work that didn't like her so they poured sugar in her tank... that comment was indirectly pointed at me because I might've exhibited my A Personality before... not the case though and he learned quickly not to mess with me. Lol
