Exhaust Plug

**OneTon** · 03-27-2017

Hey everyone,
I developed an exhaust leak today. I found that it is a threaded hole between cylinder 3 and 4 and the plug fell out. Does anyone know what threads these are?

I can confirm that it is not 1/8" or 1/4" MPT.

I know it's not any help to you, but thanks for giving me a place to look for my new exhaust leak! It's killing me, i've looked everywhere, LOL.

Haha...no problem. I fired the truck up today and it was fine for about 10 seconds, then instant exhaust tick. That hole is near the turbo and my gut dropped thinking my turbo was hosed. I was giving things a once over with it running and ran my hand across the side of the manifold when some serious air flow blasted my hand. I even looked for the plug that may have fallen out in the driveway...no luck.
