Keeping Your Intake Manifold Clean

by editor

Keeping your intake manifold clean is vital for keeping your diesel healthy.

It’s inevitable that, sooner or later, a diesel engine will have an issue with black gunk clogging up the intake. If left unattended for too long, it can cause all kinds of problems for the longevity and performance of the engine and an expensive trip to the mechanic.

The gunk is caused by two emissions-control systems inside the engine. Namely, the positive crankcase ventilation (PCV) valve and exhaust gas recirculation (EGR) system. These gasses contain soot, hydrocarbons, water vapour and other impurities that often build up inside the intake. The oil vapour from the PCV valve and the soot from the EGR system don’t cause any harm on their own, but when they mix together the product is a thick black paste that clogs up an engine and leads to power loss and a multitude of other issues.

The only way to stop this from happening is to fit up a good quality catch-can like the one from RYCO Filters.

A catch-can is basically a filter installed in-line between the crankcase ventilation tube and the intake manifold recirculation inlet. It works by removing the oil from the air that’s released via the PCV valve. The impurities are trapped in the coalescing filter and drip down to the highcapacity, 310ml reservoir. The reservoir has an 8mm quick-drain fitting so oil and sludge can be easily and cleanly disposed of. If the catch can is not drained, and/ or the filter becomes blocked, the RYCO RC351 Catch- Can also comes with an internal relief valve that limits crankcase pressure for engine safety. The RCC351 also includes internal baffles to ensure captured contaminants stay put in the sump and don’t find their way back into the engine air intake.

RYCO offers catch-can fitment kits to suit a wide range of vehicles for a clean, stress-free install.
