Source for EGR Valve?

[brn agn]

I've been trying to track down the reason our TTA has been running high BLM's and high O2 readings. To make a long story short, I found a couple of small pre-O2 sensor exhaust leaks as well as some vacuum leaks. I pressurized the intake tract with approximately 10 psig of air and found that the EGR valve is leaking in between the diaphragm housing and the lower plate. I was told that GM discontinued this item, so I went to the local parts store. They had what looked like a "universal" EGR made my Borg Warner. I didn't trust it, so I didn't buy it. Does anyone know of a source for leftover GM EGR valves? Has anyone had experience with aftermarket ones? Are the EGR valves for the TTA's the same as the ones for the Turbo Regals? Thanks in advance.

I contacted my local chevy dealer and ordered a EGR From them today, Now they may say that they are discontinued but the part number has been changed.

Here's the number for a 89 TTA's -EGR
GM #17111570

Hope this helps...
