does this modified UIM look okay?
I am installing a Bob Dillon modified UIM and need some advice. Take a look at the following pics and see if this looks overly warped. Between the throttle body and the UIM, I can see the orange gasket. Maybe some of this is normal, but I don't remember if my old one did this or not.
Thanks for any help!

Yes, the pics are after tightening. I removed the uim and put my old one back on, and it had the same gap. I don't know anything about the guy who modifies these, but I'm assuming he must check for unacceptable warpage on the throttle body surface??

I believe Bob D does check for warpage.
If your old one was the same..please take something you know to be true and flat..use that to see if your TB is warped somehow.

I can bet that the TB is somehow warped if you put it on both and they are both warped. Set you TB down on a flat surface and shine a light at the bottom. See any warpage?

That gasket surface is fine. Remember the gasket goes down into a groove in the manifold.
As I remember, that'* a UIM with plugged upper passages as well, so you're just sealing vacuum, not holding coolant coolantpressure.
Boosty, you ever seen a throttle body surface (the throttle body itself, not the UIM surface) that warped? I haven't.

I have the same issue with my UIM/TB, and my car seems to run fine. Mine might not show quite as much of the gasket, but there is a visible gap. Run it and see how she performs.
