German JDM Engines? Hardly.

Recently, several people have contacted us looking for JDM engines for German vehicles. This disturbs me for a few reasons that I’ll share. First, I’ll go into detail about JDM engines and why legitimate JDM engines (actual engines imported from Japan) can be of tremendous value to you, our reader. You’ll see why people hear about JDM’s and get excited about them – and are thus susceptible to shysters who lie to them and engines they claim to be JDM’s which are not actual JDM engines.

The reason people get so excited about JDM engines is that by and large they typically have much less wear on them than their US counterparts. Many years ago, Japan passed laws called “Shaken” laws, which affect vehicle warranties and inspections. After 3-5 years, it becomes prohibitively expensive to keep vehicles that would be sought after in the US due to heavy taxes and inspection fees. Japanese drivers pay private companies to dispose of their vehicles. For several years, these vehicles were recycled completely for their metal only.

So, 30+ years ago Japanese business men realized that when they crushed these vehicles, they crushed money. Japanese auto makers were expanding into international markets and selling vehicles with identical drive trains in each of these markets. Laws made it very difficult to import used vehicles into the US, but parts vehicles were another matter entirely. Even with high tariffs, the market was profitable enough for several companies to enjoy modest success exporting Japanese Domestic Market engines (JDM) into the United States for resale.

In the 1980′s, the US and Japan signed special treaties which lowered the tariff on JDM’s to a point that allowed much greater profit in the industry. The late 90′s and early 00′s were the golden age of JDM’s, with good availability and fantastic pricing. To this day, JDM’s represent the best deal available on engine replacement for many vehicle models.

There have been some setbacks in the industry that have lead to lower profit and availability.

The first setback is the increase in the number of vehicles that are exported from Japan to non-US countries as drivers. China absorbs a tremendous amount of these complete non-parts vehicles and New Zealand has been called the Island Subarus go to when they want to die in peace. Many go to South Africa. Many consumer groups oppose the import of complete vehicles as drivers claiming there both safety and environmental impacts not accounted for. They are concerned that the older vehicles are not as safe as newer vehicles and that keeping older vehicles on the road increases the amount of pollution released into the environment. Manufacturing new vehicles releases much more pollution than continuing to use older, existing vehicles!  I guess newer vehicles are just prettier.

The second setback has been loss in profitability in the last decade. Exchange rates and regulatory environments have changed, and many of my sources in the JDM world claim they prefer to export to South Africa, Israel, New Zealand, and Australia over the US and Canada. This has served to raise the price of JDM’s in the US and lower the overall availability.

The third setback has been the manufacturers themselves. Japanese auto makers are well aware of JDM imports into the US, and have actually taken steps to limit this as a repair option by by selling different displacement engines and using different fuel delivery systems on otherwise identical engines. A prime example of this is the 2AZF engine manufactured by Toyota. When it came out in the US and Japan, the US version used fuel injection, while the Japanese versions used direct injection. Only in the last several years have the US versions begun to use direct injection. Thus, there is a year range of Camry engines with no JDM available. There is a similar situation with Nissan Altima 2.5L QR25DE engines. Interestingly enough, these engines are also among the pricier engines from wrecked US market vehicles vehicles.

I wrote this blog because of “German JDM’s” and now that I’ve done a broad overview of JDM’s, I’m ready to come back to that. German JDM’s are rare. It is possible to get them, but highly unlikely. Where a Toyota or Nissan are a throwaway car in Japan, imported cars are not. When I look at JDM options in Japan, the German engines we see are much higher mile than their Japanese counterparts and thus don’t test out as well. German vehicles retain their value in Japan unlike Japanese vehicles, and are thus driven longer. JDM suppliers simply don’t represent a good, consistent source of German engines.

Problems with the Ford 6.0L Power Stroke Engine

Navistar International has manufactured the Power Stroke diesel engine series for Ford since 1994. The one exception to this is the 6.7L Power Stroke diesel engine, which Ford will manufacture in-house using Ford software beginning in 2011. The long relationship between Ford and Navistar, which dates back much farther than 1994, has been fruitful. The Power stroke diesel engine series, in particular, has earned a strong reputation for both power and durability.

This dependability has made the Navistar-Ford engine series an extremely popular choice both as a new and as a used engine in a wide variety of trucks and other types of vehicles. Nevertheless, there has been an exception to the rule, the 6.0L engine introduced in 2003 as a replacement for the 7.3L. Not only was this diesel engine unable to live up to those lofty Power Stroke standards, it earned one of the worst reputations of all time among all engines in the diesel industry.

Much of that reputation was underserved. Nevertheless, it was so prevalent that just two years after Ford had introduced the 6.0L, they were already preparing to replace it with the all-new 6.4L Power Stroke. By the 2007 model year, that transition was nearly complete. Ford did, however, continue to use the ’07 engine in the full-size vans of the E-series through the 2009 calendar year. When the last E-series van sold, Ford officially retired the 6.0L diesel engine, but of course, they will continue to support it for years to come.

The debacle with this engine has created some opportunity for the consumer who would buy the 6.0L as a used engine. There are many aggressive deals available, and the engine is not nearly as bad as the reputation suggests it is. In fact, the 6.0L met all emission standards and it survived stringent testing during both the research and development stages. In other words, the engine should not be problematic in its stock form, which means that most issues arise in application and modification.

The statistics support this. According to the experts at Diesel Tech, this engine rarely experiences major failure when operating at stock power levels. Therefore, there’s tremendous value here for the consumer who is aware of the common issues and the steps needed to counter them. Let’s examine the most frequent issues, which should help you decide if this used engine makes sense for your situation.

The most common problems that this engine series succumbs to, and the ones you’re most likely to experience from a used engine, occur with the EGR. In one common case, the EGR cooler simply fails because of blockage that occurs due to its restrictive rectangular design, which is inappropriate for the application. In the other common case, the EGR valve sticks due to carbon buildup, which occurs during engine idle because of low combustion efficiency at those speeds.

It is important to note that these common problems with the EGR system play a strong role in the head gasket failure for which this engine is so infamous. Therefore, it is vital when purchasing this used engine to ensure that it already has an upgraded EGR cooler installed, or that you factor in the additional expense of one, and include this upgrade during the installation of the engine or even install it yourself after the fact. EGR upgrade kits are not difficult to install, but the process is time-consuming and requires a professional set of tools.

Another factor that plays a role in head gasket failure on all 2003-07 engines are the head bolts that Ford used. These are not generally an issue with the engine in stock form, but many owners will simply have them upgraded if they ever need to replace the head gasket. However, upgrading the head studs is much more of a necessity for a modified engine because the factory bolts displace load unevenly, and problems will manifest quickly at anything above stock power output. Therefore, this is an important consideration due to the expense of the upgrade if you’re dealing with a modified engine or plan to modify it yourself.

Turbo failure is another common problem, and in the 2003-05 models, this occurs because of the restrictive oil drain tube that Ford used. The good news here is that this is a relatively inexpensive upgrade. Ford attempted to rectify this problem for the 2006 model, but they actually worsened it because the new system lacked an internal turbo groove. Ford corrected this problem properly for the 2007 model, and the 2007 version is the most reliable turbo system ever made for this engine. When buying a 2006 engine, it is best to seek one that already has the 2007 turbo unit in place because that upgrade is inevitable.

In addition, when Ford launched this engine, it included an improperly calibrated ICP sensor. All engines from 2004 on have the correct ICP sensor. For owners of a 2003 model, it’s important to recognize the issue because many inexperienced owners will spot oil beneath the truck and assume the worst. However, if the oil is leaking beneath the turbo, a bad ICP sensor is generally the culprit, and replacing it will correct the issue. This is an inexpensive part, and a simple installation, and you should expect this part upgraded as part of the installation process, if not already installed.

The bottom line is that this engine, despite its dreadful reputation, can be quite durable and a fantastic value. When buying used, there are a couple of keys to a successful purchase. First, buy through a respectable dealer. You should have free, thorough access to the engine history as well as a minimum one-year warranty with the option to upgrade to two. Second, choose your mechanic carefully. Especially with an engine like this one, it is vital that the mechanic adheres to and makes the adjustments according to all of the technical service bulletins during the install.
