Isuzu is known not only for all-terrain vehicles, but also for the diesel engines supplied by many of the world's automakers. Made in Poland, the 1.7 DTi / CDTi is under the hood of the Honda Civic, as are many Opel models. The 1.7 CDTi engine doesn't cause much trouble up to 250.000 kilometers. It may be different later.
1.7 CDTi engine - from 80 hp to 130 hp
In fact, this is an Isuzu engine design. The Asian manufacturer in the 1.7s was heavily focused on creating powertrains for other brands. One of these engines was a four-cylinder diesel 1999. General Motors, the owner of Opel, became the largest customer. Initially, the engine was also under the hood of Honda. He began his career in the market in XNUMX under the guise of Astra G. Interestingly, from the very beginning of production it was made at the Polish GM plant in Tychach.
The first DTI version 1.7 is equipped with direct fuel injection realized by means of an injection pump. A major modernization took place in 2001. At that time, the Bosch common-rail direct injection version debuted. The engine appeared under the hood of the Honda Civic, and in 2003 in many models Opel. In this version 1.7 CDTI makes 80 and 101 hp. In 2007, the offer was supplemented with the following versions 110 and 125 hp. The next improvement occurred in 2010. By the way, the power of the most powerful engine increased to 130 hp. Weaker variants are equipped with fixed turbocharger geometry, while others have more advanced turbines with variable geometry. Unfortunately, the pro-environmental aspirations of the manufacturers have hit this engine as well. From 2007 in the Zafira and in 2009 in other models, the DPF particle filter is fitted as standard.
Despite many years of presence on the market, the manufacturer did not deal with the loud operation of the engine, as well as the flexibility of the 130 hp engine. The 1.7 CDTI achieves maximum torque much later than competing engines and is not as economical. It is combined with a five-speed manual transmission as standard, while the most powerful versions are connected with a 6-speed manual transmission.
With the 1.7 CDTi engine, you are still the first 200.000 kilometers
The vast majority of users agree that the first 200-250 thousand kilometers should go only to regular services. Only at higher mileages do problems with engine equipment occur. In the weaker versions, the turbocharger proved to be very durable. If the driver follows the recommendations of experts, this element will last over 250-300 thousand kilometers. Versions 1.7 of CDTi engines equipped with a turbocharger with variable geometry have more problems. This is where the geometry control valve fails. As a result, engine power is reduced and fuel consumption is significantly increased. A much higher cost will be the overhaul of the entire turbine.
The oil pump is leaking
Bosch better than Denso
Driving around town is bad for a DPF filter
Conclusion - 1.7 CDTi engine
