Mad,
I didn't see anyone else mention it thus far. Perhaps you want to add the "magnet on a stick" check. If your plenum has been replaced with the popular aluminum part, a magnet will not stick to it. If the magnet sticks, it's probably the OEM part.

I like those flexible reaching tools with the magnet on the end. You know the one, the one you reach for when you drop that socket into a tight space and you can't get your fingers in the space to retrieve it.

 

here's a lot of pictures, parts list, and cost.
+1 on the long stick magnet to check whether your plate is oem steel or aftermarket aluminum. oh wait, i might have been the one to think of that. lol. damn good idea.

If you wouldn't mind elaborating on this^^ a bit, I dont mind adding you to the credits for it.

Added the link and major props to OP

 

remove air filter and open the throttle plate. stick a magnet like this down through the throttle body to the plenum plate. if it sticks - then you have the original steel plate - and you need to replace it. if it doesn't stick, then you already have an aluminum plate, and its likely not leaking.

@Purple... my computer has probably lost its mind... can't jump to your product links for the above parts.

Can you post just the part numbers?

 

I had the same problem, that's why I didn't amend the OP to include the links. you may have to go to the websites mentioned and search for the parts in question.

 

Your computer isnt crazy. Those links are old. I'll fix it later. I've gotta go!

 

Yesterday I found out that my plate is original, going to end up replacing, just out of curiosity, if you were to just replace the gasket and not the plate, how long would it be until the gasket fails again? I already got my plate from hughes.

 

If you already have the hughes plate, why wouldn't you install it???

Just replacing the gasket will guarantee you will get to do the job again, timing on that is variable though. If you replaced the gaskets, AND did something about the too-long bolts that hold it in place, it might be a permanent fix. Maybe.

 

No no, I am going to use the plate that I bought, I was just curious of have long the gasket would last if someone were to just replace it and not the plate, because I don't know when the previous owner fixed the gasket.
