How to Block EGR Valve Paccar MX

In this Post, i will show you How to Block EGR Valve Paccar MX series after Delete

The basic principle for blocking off EGR is the same on all engines (Cummin and Detroit, you can refer old post on this Page). EGR has to be blocked with steel plates on both cold & hot side.

1st block off plate goes on position where EGR manifold meets exhaust manifold.

2nd block off plate goes on position where EGR manifold meets intake manifold.

The reason we recommend blocking off EGR on both sides, is because that way engine will run the best. Once You block off intake(cold) side, Your intake manifold air volume & geometry will not be messed by EGR tubing. There will be no chance of sucking air from EGR manifold, and that way causing an air leak.

Same thing is for exhaust(hot) side, Your exhaust manifold geometry will be again according to factory spec.
