Why did you tap it at such an angle? And I don't think you got enough JB Weld on there.

if it weren't for the jb weld, those threads would fail. they're not even threads. they're just angled lines. did you oblong the hole to make the tap thread? I don't even know how you did that. As a machinist I've had my fair share of **** ups, but I've never done that, much less on purpose.

Cause if I tapped is straight I wouldn't be able to connect the 45* -12AN to hose fitting to it as it would interfere with the power steering lines and steering shaft. I was going to just cut the 3/4" NPT end off the fitting and have it welded to the pan. Then, I'd barely have enough room. But alas both my welders are either busy or out of town. So I taped it at an angle so it would fit. And JB'd it so hopefully it won't leak. I have another 99' oil pan and this summer, I'll redo it right when I build a motor. Just hope this works well till then.

And yeah, I got the industrial size JB weld.

Yeah, it would never seal without the JB. I had to drill it crocked and that was hard. Getting a tapered tap started that crocked was even harder. I know it ain't pretty, but it's actually pretty damn solidly mounted into the pan. Just hope the JB keeps it sealed. I've JB'd oil pans before though, so I'm confident it will hold.

EDIT: Also, what you can't see is that before I JB'd it, I scratched the aluminum up very well around the fitting, and scratched the anodized **** off the fitting too. So it was well prepped.
