Chevrolet Repair: Tracker intake manifold frost plug, rabbit ears, frost plugs

Question
The frost/freeze plug has fallen out of the intake manifold (located UNDER the manifold OPPOSITE from #4 cylinder) on my '92 Tracker (4x4). Do you have any idea what the size is (most important) and is it possible to fix with out removing the manifold? I thnk with a few well placed clamps I can squeeze it in to place what have I got to lose!
Thanks, Pat

Answer
Hey Pat,

  I can't remember what size it is but there are a couple of solutions that I can recommend that will be permanent fixes.  If it is possible for you to take a picture of it you can email it to me at waynehowie@rogers.com and I can walk you through it.
 You can buy aftermarket frost plugs from parts departments that are somewhat variable in size and have either rabbit ears on the back (like a block heater) or a collapsable plug that makes the plug larger when they seal.  A block heater works as well.
 If it is a small hole like 10mm-15mm you can tap it out and use an oil pan drain plug and gasket with some teflon tape.  Pressing in a new frost plug on the vehicle can be tough to do and even harder to get it to seal.
