Title: Turbo problem?
Post by UncleSam on Apr 26^th, 2007, 5:41pm

Hi there, I own the '97 Scorpio 2,5TD, and I wanna know if my turbo is functionall, is there any way to test it at home? Because I think that it's not operational, because I don't hear it and I don't feel it too.

Thank for the advices ;)

Disconnect the large rubber air hose going into the inlet manifold and get an assistant to hold the engine at about 2000rpm. There should be a strong draught out of the hose, like a hair dryer on steroids!

In all probability, if there is a problem with your engine it's more likely to be the electronics controlling it than the turbo itself - provided good oil has been used and the air filter is in place they don't very often fail unless they've not been allowed to cool & spin down before switching off the engine

As yours is the later TD engine, you can run an OBD-II check on it as per the petrol engines; this may help you identify where the problem (if any) lies...

Hi in theory you shouldnt be able to hear the turbo, loud noises/whistling is usually a bad sign. First off try as Darren says and see if its spins up nicely, and maybe check that none of the air hoses are split anywhere as you'd loose all the boost made by the turbo into the air as opposed to the engine.

if yours is an auto then you probably wont feel as much of a kick as the 'box will smooth it out a bit.

Golden rule with Turbo's, if you've not had a car with one before.

ALWAYS make sure that you do regular oil changes. Turbos like really clean oil. Old or dirty oil is the quickest way of ruining them.

Most Turbo manufacturers suggest that you let a Turbo spin down for about 20 seconds after a fast drive. Never just turn off the engine. Helps to lubricate the bearings when it shuts down. This is VERY important, because turbos spin at over 25,000 rpm in most cases and don't take kindly to being shut down suddenly, as it can starve the bearings of oil when hot and means that when you next start up, wear is more likely.

Good advice because they can be VERY expensive to replace. ;)
