Quick, throw open my hood and there as plain as "dog's balls" is the Off-Center thermo' on my own manifold. :--) I didn't just supervise the screwing up of my truck I had to do my friend the favor!!! Ugh. There was no small indent or ridge like my manifold to remind me of this basic, but important little detail!
We immediately exchange high-fives with this technical revelation and perform the rare and delicate "Oblique Thermocouple" installation that you have only read about but never seen! Incline bit 30 deg. Towards Firewall and exit the manifold divider at full pucker factor! Lovingly insert tap and while steadying it nearly all the way, screw it home to the hilt with a small wrench at this queer angle. .
After removing much filings and cleaning threads we can see that we probably DO have enough meat to securely and with a good seal install the thermo' sleeve. We go for it and the rest is 9:00 PM driveway, diesel mechanics' history!! It works the nuts and NO Leaks... Whew!
Like I said. . Thermocouple narrow escape!! Ha, Ha.
Luckily, my buddy still talks to me.
