I have an Explorer TB and a stock EGR spacer that has been bored out to 65mm. I ordered a set of BBK part #1572 (65-70mm) gaskets from O'Reilly Auto. The intake opening in these gaskets are too big and won't seal coolant or EGR gasses.

I called BBK, the guy on the phone was super nice, and said it has happened before and that he would personally measure the replacements to make sure they were the correct size. The new ones arrived and one gasket is correct, but the other is still wrong.

At this point I'm done dealing with BBK, and I still need a set of gaskets that will work. Any suggestions?

The problem in the gasket fitting properly might be due to having a stock spacer that has been bored out. Perhaps the BBK 65, and 70 mm spacers design is different than if you took a stock spacer and bored it. I'm not sure this is the case, but worth looking into.

EGR gasket side. It measures 70mm

Coolant side, the gasket it measures 77mm and will obviously leak coolant. This is the replacement kit that the guy at BBK personally measured.

This is the 77mm gasket on the throttle body. It won't seal on that side either.

I'll call them today and see if they can measure a gasket while I'm on the phone with them.

I just got off the phone with BBK. They are going to try to figure out why I keep getting oversized gaskets. Fingers crossed they get it figured out and I get the right gasket.
 
Here’s what I used.

And the fit in my 75Mm spacer.

It’s great that BBK is trying to help, but these were $2 and $3 gaskets on rockaito. Maybe a few bucks more at auto zone if you really need one today
 
The 75mm would still be too big. I'll wait for a response from BBK and if that doesn't work I guess I'll get some stock gaskets and cut out the center to fit.
 
The Explorer part #'s Mustang5L5 listed are what you need.
The id of the TB to spacer gasket measures 67mm,the id of the spacer to plenum gasket measures 70mm.
The Explorer TB is 65mm,not sure why you think stock Explorer gaskets won't work.

Good luck

All in one thread. Got gasket part #'s and confirmation of boring the stock egr. I could see enough material there from a pic i just looked at, just thought it might chatter on the side with no support connected to the OD.
