Alright, here we go.

Is the location of the EGT temp probe supposed to blow air in a positive pressure situation?

I don't have anything in there. Perhaps it had a solid gasket in it before that is now blown through?

Or maybe there was a plugin there before that blew out.

So far, that's what I've found with a leaf blower stuffed up the tailpipe.

Thanks, please keep us posted on what you find.

Just seen your most recent update.

Yes, there should be a gasket and 1/8” NP plug in the rear block off plate.

This is where the air is coming from pretty expeditiously, and you can see above it where the firewall insulation has been damaged by the air blowing through it.

It's fixed-ish.

I had a hell of a time finding the right size/thread to fit this thing.

I started looking for 1/8th NPT and didn't find anything.

After much trial and error, I found a 3/8 - 24 x 1 that seemed to fit the thread.

I wrapped it in tape and used a 1/2inch spacer not to drive it all the way down.

Shortly, I will either buy the EGT probe or another plate to block it in a less janky way.

Thank you all for all the help.

Hopefully, your fix will hold up.

The threads in the plate are 1/8” NPT-27 TPI.

Any plumbing store will have them.

Just curious, with the leak fixed, are you still seeing a negative boost at idle?

Nope, the negative boost is gone.

It fluctuates from .03 to .06.

I spent 2 hrs at lowes trying to find something to work.

I'll check into plumbing supply around here this weekend.

Thanks for your help!
