Do you have any more pics of the hood vents?

I just picked mine up today, 6x8 blackout. Excited to finally own one, we first saw these back when sportsmans had one displayed about 8 years ago.

Ok boys and girls, I seem to have it fixed. Came to the conclusion that there was no way that brass plug was going to fit in my block so I did some mud searching, and ordered a couple of the other plugs that were used on other 80s. Turns out petcock style plug is the one my block is sized for...

You may have been mistaken on thread pitch, but I was mistaken on which bolt I had used, and it was in fact 14x1.5 which is 17 threads per inch, which makes you actually correct. Haha we will just call it even Anyways, I took it by a machine shop I use through work to settle it once and for...

Here is a side by side of the new plug with the old plug, you can see the first few threads on the old one are almost completely flat.

It is a new plug from toyota, and I agree with rifleman that it's probably just a burr. But all the Internet cruising says 14x1.25 is 20.3 tpi. Not trying to argue, just no one has specifically confirmed it's bspp, just what we were all figuring since everything else seems to be that way.

I looked at the threads today with an inspection camera, and there doesnt seem to be any sign of cross threading. I assume the only reason the npt fitting will even start is because its close, and tapered. That rambling was just frustration and exhaustion coming out. Its amazing how much...

Oops posted twice.

The threads are shiny because I was trying to clean them with a small wire brush. Not sure where I can find a bspt tap to chase threads with.

Looking into the hole there doesn't seem to be a tapered seat. the protrusion ahead of threads must be to make it much harder to get in crooked and cross thread. On another note.... new plug does not want to go in, doesn't even want to start. The threads look good aside from some corrosion...

I think you are correct judging by the picture. I'm guessing by the way mine came out, whoever removed it last cranked it in smashing the first few threads into the tapered seat.

In case anyone comes across this looking for the part number. The plug is 96431-23814 Got one coming

Isn't the oil pressure sender threads also british? I didn't know that about the knuckle plugs. Continued searching found 90910-09129, its the drain cock, haven't found a part number for just the plug yet. Anyone know if it will work?

That's pretty much how it worked out. I matched it up with my tap set, chased the threads, and used a bolt with a little Teflon on it so I could finish flushing the coolant. Hopefully the dealership can get me a plug soon. Thank you for the help:cheers:

Its the plug that has marred threads, might have had some crud in the threads on the block. Didn't kill the whole plug, just the first thread. It seems the thread is 12x1.5,
