Before condemning the turbo, check all the engine settings, injectors, breather hoses and air filter. On Ninety or One Ten TD check the tightness of connection between the compressor and engine intake manifold, and of connections to exhaust manifold and downpipe. Oil leaking at the turbo exhaust connections is probably due to general engine wear.
Problems are difficult to diagnose, and many a turbo has been replaced only to find the fault was elsewhere. Always check with a specialist. All engines running consideration should be confirmed as satisfactory and mechanical components, especially fueling and air induction parts, in serviceable condition before questioning the turbocharger and its actuator system. If any engine faults exist, simply renewing a turbo will not rectify or overshadow them.
If the turbo does need replacement, it’s important to find out what caused its failure so its replacement won’t be similarly damaged. Typical symptoms include reduce performance, increased performance, excessive smoke, higher fuel consumption. All these can be caused by modulator problems and (TD5 onward) by electrical failure such as cable breaks and poor contacts and earth connections.
