Yeah, 'er 'uh, 04hd103,
Had the same experience at 7000 miles. [smiley=oops.gif] I had one of my welders repair mine, as I did not want to wait to get the new one "Jet-Hot" coated, which is a procedure I highly recommend, not just for the 1 extra horsepower it produces, but for the added luxury of the coating not reflecting the blue, black, and purple high heat colors on your Primary! [smiley=thumbsup.gif] At any rate, when you reinstall, put a piece of carboard between your Primary and your header pipe before you tighten. Then, put rubber washers, in addition to the chrome washer, on both sides of the mounting bracket on top of the transmission. Then snug. DO NOT TORQUE!! It has to have a little give, or it will fail again. [smiley=furious.gif] These instructions came directly from Gerald Rinehart, who, incidentally, is a personal friend of mine. Fixed. No Worries! Later--HUBBARD
