You'll have to buy the tester....Don't remember how much they are, but I did see one the other day online for ~$50. You'll also need an air-compressor. Instructions come with the tool.
Good luck. I'm going through the same thing....Pretty sure I blew a HG w/only 120 miles on the new motor... She's comin' out now!

I hear ya! I've been chasing down oil & water leaks for 2 weeks now! Pulled the Tremec 4 times, changed the rear main twice, pulled the engine out (just a little for clearance) too many times to count, changed the lower intake/gaskets 4 times & now I'm pullin' it for HG's!!! Oh, & I've only got 3 more weeks to work out all the bugs before Byron chips it.... Ah well, it'll be WELL worth it when we're done.
