1.6 HDi 110hp
a series of problems
Carbonized oil in a diesel engine is nothing new. But this engine's oil sucker and turbo oil supply screw have been a source of trouble. Come and discover this and other problems that plague the 1.6 HDi of 110hp.
In this article we will address one of the initial problems of the 1.6 HDi engine. This engine is very versatile and has been used on a large scale. From a Mini to a Mondeo, it seems like it's everywhere.
Here we will see the problems associated with the turbo GT1544V 753420.
Let's start with the most common problem, the oil supply screw. This screw incorporates a pre-filter. Initially this filter was a small metal mesh, prone to blockage and carbon accumulation.
The small metal mesh would later be replaced by a larger plastic mesh that would guarantee an adequate supply of oil.

Another less common but equally serious problem appeared later. Originating from the injectors that let compression from the cylinder to the oil circuit, the oil sucker in the crankcase clogs, severely restricting the flow of oil.
Replacing the injector and replacing or cleaning the oil circuit solves and prevents future problems.
Still on the turbo but already out of the lubrication problems the design flaws remain. Despite the various version revisions made to the turbo GT1544v 753420, none solved its Achilles heel. Having no design obligations with the brand, after-market turbo repair shops rushed to change the geometry of the turbo, which is originally weak and prone to constant failures with terminal consequences for the turbo.
Along with other minor changes to the turboshaft and turbine, the NCturbo version of the GT1544v is technically superior to the original and has proven to be extremely reliable while still achieving similar levels of performance.
