So, should you buy the Subaru 2.5 engine? The answer is yes, you should buy it. But you also need to be aware of what you are getting yourself into. Knowing the downsides of the engine will mean a lot for you since you will be prepared for possible problems that will often know to happen as the problem with the head gaskets, and the problem with the oil which is known to burn in the cylinders. In 2010 the L3-VDT was revised to fix some of the common failures, the shape of the cylinder head was reworked, possibly to concentrate fuel near the sparkplug, the ECU was made faster and featured more air/fuel cells to reduce the chance of the engine leaning out. Another change was a fix for the timing chain tension issues. The turbo seals were also updated. Now before we dive into the Subaru 2.5 engine. Let’s first discuss the pros and cons of this engine design. This is quite useful to know because everything revolves around the pros and cons.

The possible outcomes from a blown head gasket can lead to the mixing of coolant and oil. And this mixture is not good since the bearings inside of the engine will get toast if you run your car like this. This means that the whole engine will have to be either rebuilt or replaced. So, beware of this problem. Now let’s move to the other problems of the Subaru 2.5 engine. Subaru 2.5 Engine, Problems #2. Oil Consumption This is simple to use online converter of weights and measures. Simply select the input unit, enter the valueAll Subaru 2.5 engines are interference engines, which means that if the timing belt breaks, it can cause serious damage. Meaning that it is quite more probable for them to leak since they are installed in this way. On many of these engines, the coolant leaks from the sides of the engine since the gaskets are tiny, and as they degrade, the coolant escapes and burns off. The EJ25D was replaced by the EJ254 and EJ257, which are dual overhead cam models used in a limited amount due to the flat-four’s complex architecture making changing plugs difficult.

Four series of turbocharged 2.2 and 2.5 liter engines were produced, normally referred to as Turbo I, Turbo II, Turbo III, and Turbo IV. The primary difference between these engines was the use of an intercooler (in all except Turbo I). The Turbo III, ironically developed after the Turbo IV, pioneered returnless fuel injection, and was coupled to high-performance, four-valve-per-cylinder heads, bringing 224 horsepower (167kW) from the 2.2 liter engine. The Turbo IV pioneered the use of variable nozzle technology to minimize lag. [2]In conclusion, while the Subaru 2.5 engine is known for its durability and performance, it does have its share of common problems. Regular maintenance and timely replacement of faulty components can help prolong the life of your Subaru 2.5 engine and ensure it continues to perform at its best. Subaru Boxer Engine Reliability The original 1993 Duratec V6 engine was designed by Ford and Porsche. [1] Ford introduced this engine in the Ford Mondeo. Over time, "Duratec" became an omnibus name for Ford's gasoline engines unrelated to the original V6. The Ford Zeta engine, Ford Sigma engine and Ford Cyclone engine all carry the Duratec name, but are otherwise unrelated to each other or the original 1993 Duratec V6. The ambiguous use of the name is similar to Ford's use of the Zetec for the previous generation of gasoline engines, the Duratorq name for diesel engines, and EcoBoost for turbocharged gasoline engines.

In 2012, Ford added the 1.5-litre, closely derived from the 1.6-litre engine. [5] Bore was reduced from 75 to 73.5mm while the stroke remained unchanged 88.3mm.
