"my VIN number is
JHMAP11412T001732"
JHMAP11412T001732"

I think with that VIN you're OK. With the '2T' vin series the affected range is prefixed with '1130', (yours is 1141), so I am pretty sure that means you are outside the affected range of VINs. If I understand the VIN correctly, and so long as you've not had an engine swap, you should be ok. But, could someone else confirm if I am understanding the VIN range correctly?

Hey sorry to bring up an old thread but you can go ahead and add me to the list of dumb asses that went ahead and ****ed up their oil jet bolt holes. Before I nut up for the helicoil I just wanted to ask, it's cylinder #4 and I ****ed it up because I started tightening it when the squirter itself wasn't seated properly. I backed the bolt out but now I can't even get it started back in the threads? Any chance this is still salvageable like I only messed up the first couple threads? Or do I just need to go ahead and order the helicoil now?

Ah man that sucks. Having replaced mine I think I'd be trying to place it as square as possible to the hole and applying pressure whilst turning to get it started. Assuming it's only the first thread or so that's stuffed.
I however am not a mechanic so I'm interested to hear what others might suggest before taking action.
It doesn't help that space is at a premium with this job.

If the jet wasn’t seated, then you likely pulled the first 20% of threads. There will still be enough thread to torque the bolt properly
Using an old jet bolt as a tool (no jet), run it all the way in and out of the block. It is CRITICAL that you do not cross thread here.
you can also take an old two-hole bolt, and grind/taper off the first three threads. The tapered part will pass the damaged threads, and help you align by finding the undamaged threads.

Thanks for the quick replies fellas. I took your suggestion Billman and did manage to get one of the old bolts to thread back in, but it wouldn't properly tighten. For better or worse I just went ahead and put the new one in, tightened it down as much as it was willing to and sealed everything back up. Here's hoping I get another 100k out of it but if it backs out and wrecks the engine tomorrow oh well lmao. Gives me an excuse to put a B or K series in for some cheaper power.
Still kinda pissed at myself tho, of course I got every other cylinder perfect but the easiest one is the one I manage to **** up

This is why I always caution to be careful that your efforts to prevent something don't inadvertently cause it.
In this case its the demise of a still healthy engine. Not putting in the updated oil squiters risks engine damage under very specific conditions. Doing engine surgery to install them has its own risks, of which stripping the threads is among the most serious. Now this otherwise healthy engine is in more peril than if nothing had been done at all.
I will reiterate. In all things, always be careful your efforts to prevent something don't inadvertently cause it.
