The Problem: Carbon Buildup in Diesel Engines
Intake manifolds on modern diesel engines face particularly harsh operating conditions.
The Deadly Combination When oil vapor meets exhaust gases in your intake manifold, they combine to form a sticky, carbon-rich deposit. Over time—typically 80,000-150,000 kilometers—this buildup can become severe enough to cause significant issues.
