Back in the end of May this year, I had a brand new Tial MVS 38mm external gate with o2 housing from punishment. Less than 500 miles later, I got a "no boost"problem. Turns out after checking everything and finally pulling the turbo, that the wastegate spring had infact heated up from all the under hood heat my tubular manifold was putting out and compressed and stayed in the compressed state causing the gate to open at even 1 psi. (I could blow on the nipple with my mouth an the gate valve would open) and this was on the 17psi spring. So punishment sends me new springs, I put the new springs in and bolt everything back on minus the tubular mani wich I swapped my ported stocker back in to lower temps, and was boosting again. Fast forward to today. Car was parked for the month of june while I was in england so its only been driven since july to now. I am away for work for 2 weeks of each month as well so car is parked for half of the 2 1/2 months. Well I have about 800 highway miles on it and once again am getting no boost, same symptoms as before, this time I was boosting no problem, picked my daughter up from school and on the way home had no boost, just like that it was gone. Did BLT, held 35psi no problem, tightened down all Manifold bolts, did a compression test and got 160,155,150,160 (not bad for 100,460 miles and running 25 psi boost on stock internals for 2 yrs) Is it possible that there is a problem with the wastegate itself causing the springs to fail?? I had the wastegate for 2 months before they failed the first time, now its been another 2 months since putting brand new springs in it and same thing is happening. Should I pick up a new wastegate and send this one back or is there a bad batch of springs and i just got unlucky both times? Kinda stumped right now on what to do as this is getting old really fast.
