If you have a diesel car, this is for you

For many years now, the government has mandated all diesels use Exhaust Gas Recirculation (EGR) to reduce the amount of oxides of nitrogen in your carís emissions. (Gas cars have it too. This is about a diesel maintenance procedure.) Since all diesels create soot, all diesels clog their intake manifolds with a rather unpleasant mix of carbon black and oil fog from the crankcase vent.

If you donít clean it out, itíll starve your motor for air. Youíll burn more fuel and create more pollution.

You have to remove it from the engine to clean it. If you break this shit loose and it falls into the engine, itíll ruin the motor.

The process is simple, if time consuming.

Remove everything thatís blocking the intake manifold. Remove that too.

Clean it out.

Put everything back where it was.

The hard part (unless youíre doing it on a VW Bug and have to feel your way around) is getting all that crap out of the manifold and the EGR valve. The ďredneckĒ way is to squirt some brake cleaner in the manifold then, with an air hose in one hand and a propane torch in the other, set it on fire. What I did was to use brake cleaner to loosen up the crud then use a pressure washer to blow it out. If you have a cast iron manifold, oven cleaner works but itíll eat an aluminum manifold.
