I take a little different approach to recommending products than some. I've been at the receiving end of high repair bills and many hours of wrenching in the garage trying to solve diesel problems without mortgaging the farm. In my own work, I wanted the best information and best possible chance of a longterm effective repair. I don't want to do the same job twice, and I'm willing to spend a little more to get a better result. As a result, my recommendations are based on that principle.

So, the best advice is to suggest to people that they buy genuine castings and engine parts authorized and produced by the OEM's. There's just too much risk in suggesting untried and unproven engine parts - from untried and unproven manufacturers. I applaud others here who have taken the time to examine these Chinese castings in detail. What isn't known at this point in time is what alloys were used in the various components. We know Navistar was tasked with solving the cracking problem AMG inherited from GM. I haven't heard from a single individual who has the 2001+ castings and has reported a crack or has reported a manufacturing defect.

The best advice is to stay with OEM parts. JMHO
