Try to blow into hose going into lower part of wastegate and check if it leaks. Small leak trough valve stem is acceptable...large leak means ruptured membrane.
Can you give me a place to buy the controlling valve and how to do this. Maybe the answer is to put the stock spring back in and do it that way.
It looked correct when i put the dia. back in but you never know until you try it.
All im asking for is 1 bar.
The dia. had a small (half way thru) crack approx 1 inch so i didn't change. Should i ?
If it had a ruptured membrane i should have no boost, no?
And yes, im reading the stock (below tach) gauge.

Any other opinions on the 1 bar spring change?
