The basic principle for blocking off EGR is the same on all engines.

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 our experience tells us that the engine will run the best this way.

Once You block off intake(cold) side, there will be no chance of an air leak.

Same thing goes for exhaust(hot) side, there will be no chance of an exhaust leak.
