My EGR explained.
One of our members had a question on my EGR. He ask how is your high boost killing the EGR Valve???
This is one of my EGR valves I was testing the exhaust pressure signal on.
This is the plate that I will use to block off intake boost pressure to keep it from killing the diaphragm in the EGR. I marked it intake and exhaust. Normally the intake hole is open. You can see by the way the EGR gasket is made.
I'm using a aluminum block off plate that I drilled a small hole into so the exhaust side can flow exhaust and I can get a pressure reading that I will use for data logging back pressure. Some how the 40+ psi is getting past the EGR stem? I didn't even have the hoses attach to the diaphragm and it still kills the diaphragm?
So now I have a copper cooling coil that then turns into a rubber hose that attaches to a boost regulator. I will be manually adjusting the amount of flow the EGR with the regulator.
