This is to help people new to Mercedes Benz diesels.

Banjo bolt location on the 1985 W126 300SD.

Rear of intake manifold.

What is it = a hollow bolt with a hole in the side to give passage.

What does it do = pass intake manifold pressure to the ALDA.

Why does it need cleaning = oil sludge, carbon and other gunk builds up and plug’s the bolt and line.

What happens if the bolt or line are plugged or broken = massive power loss.

Warning:
Do NOT over tighten the Banjo bolt; you will strip the threads from the manifold.

Note:
Follow the line to the ALDA, and remove the Hex banjo bolt from the ALDA, you should clean this bolt and banjo fitting at the same time.
