Wastegate Problem, understand problem before replying
 
I have a SSAutochrome 38mm (Tial style) wastegate with a 8.7 lb spring in it and it is hooked up on my car 100% correctly, but I am having a problem with it.. :(

Problem: The wastegate is leaking air around the valve shaft, meaning it should only take 8-9lbs of boost to open the wastegate , but instead it is taking 20lbs to open it because of the amount of air leaking between the valve and the shaft it slides in.. I tried using gasket maker to line the shaft and the valve's shaft to help close this air gap and I got the fucker to only need 15lbs to open, but this is not low enough, I need the 8lbs or so it should be without the leak.. I have tested the wastegate outside the car many o' times in the last 2 days with regulated air thru 2 regulators for my air compressor, and double checked the lbs of air a boost gauge and a air pressure gauge..

Questions:
1. Have you had this problem (38mm or other Tial style wastegate)with air leaking around shaft and not opening the wastegate at the right amount of boost like it's spring is made for because of this loss of air??

2. Do you think if/when I do get the amount of boost required to open under 10lbs with gasket maker inside the shaft with the valve sliding thru this, that it will be safe to run all the time, or is this a bullshit fix and the gasket maker is going to not work because of the heat the wastegate is going to see??

To go over this again simply:

Wastegate hooked up correctly, don't ask me about the installation.. The spring is the right one.. :-X

Air leaks around valve when under boost causing it to not open until said loss is compensated by more air in which it then opens.

Do you think my fix will work for the long run or is it a rig job that will crash and burn??

maybe its is because of your spring....i bet you it isnt an 8-9psi spring. i bet you its a larger amount of air spring.

read above, spring is correct, it leaks air...

answer to question 1... I don't know??? never used one.
answer to question 2... you knew the answer to this before you asked it. Yes it is a bullshit solution. No "gasket maker" that is fully exposed to hot exhaust gasses will stand the test of time. It's a very temporary solution at best

Problem: I have a SSAutochrome 38mm (Tial style) wastegate

Questions:
1. Why did I buy this piece of crap knowing the reputation of SSAutochrome parts?

2. Do you think if blow up my engine you guys will think I'm cool?

To go over this again simply:

I bought a piece of ---- wastegate, and I'm stupid enough to think I can put some gasket maker in there to fix it.
