I had purchased a used stainless steel 3" DP a while back from a local turbo buick shop here in town. The previous owner upgraded to a 3.5" with his new exhaust and wanted to get rid of the 3" so I picked it up for a pretty good deal. He said it was an ATR pipe, I can't tell the difference. Anyways, the puck was a little sticky when I first got it. I didn't think it would matter much but once it was on the car and got hot, the puck would start to either stay stuck and overboost or open up and not build enough boost. Needless to say the car has been parked for a good 6 months.
Fast forward to a few weeks ago, I decided to get a replacement puck from RJC which was all stainless steel and repair it myself. I cut the old pin off and had a buddy with a drill press take out the old sleeve with a 1/2" bit. Got the new stainless sleeve in flange and put a weld on the outer sleeve. Put the new puck in and weld on the puck's handle with a little less than 1/8" of play.
The puck swings freely with just a tap of the fingers against it. Well got it put back on the car this weekend and took it for a spin. First 15 mins all was good, then all of a sudden boost would spike to 20+ pounds like it did before. Got home let it cool down, and low and behold, the thing is stuck again. I couldn't even move the puck with my hands. I had to pull it off the turbo and tap the puck down gently from the inside to get it to slightly move. Sprayed it with WD40 and now its all loose and swings freely like its suppose to. What did I do wrong? Why is it still sticking even with the new stainless piece. Anyone with this issue, how did you fix it? Below are some pics of it puck and how much play it has going up and down.
