1998glanzav Posted December 16, 2008 Share Posted December 16, 2008 Hi Colin,To look with the eye, make sure that the diaphragm or housing arent cracked. The best way to test if it opens ok and what pressure it opens at would be to do the following:Put a compressor with a pressure guage or a standard air pump with guage into the wastegate hole at the bottom of the wastegate. Then apply some pressure from the pump into the wastegate and keep an eye on the guage on the pump/compressor.When the Wastegate is full open you can read the gauge and you know that the wastegate works and when the wastegate will open.I hope this helps Quote Link to post Share on other sites
