7.3L PSD Engine Failures

Hey all...

We've been asked many times for our opinion about miscellaneous engine failures, especially those relating to "windowed" blocks. After reading hundreds of posts on this subject, speaking to dozens of owners and manufacturers, reviewing carnage photos, and comparing countless files from damaged engines, we have a few theories. In fact, we've just finished writing a calibration simulator for the PSD that helps quickly identify just how significant a role tuning may or may not have had in relation to the failure.

In order to rule out isolated issues and identify any trends, we are conducting an independent survey of all 7.3L Power Stroke engine failures to see if there are any specific commonalities among the failures. The failures in questions will be specifically related to MODIFIED vehicles (i.e. Chips, Injectors, Turbos, HPOPs, etc.) and we would appreciate anyone who has suffered an engine failure of any type to please take a moment to fill out the survey. All NON-PERSONAL data collected will be made available for download to any individuals or companies that are interested.

The survey is located at --> Survey of Power Stroke Engine Failures <--

I do want to take a moment and remind people to please be considerate and use this as an opportunity to get past the old issues and move forward in a positive fashion, NOT as a means of complaining about what damaged the engine. We've all read the posts and heard the arguments, but it really doesn't accomplish anything except getting a lot of tempers flared up. We may not all have to get along, but we are all striving for the same thing... making the Power Stroke a reliable source of performance.

We appreciate everyone taking the time to fill out the survey and hope that it will provide valuable information for all 7.3L Power Stroke Diesel owners and vendors, past, present and future.

Thank you! It's still early, but some trends are definitely evident.

Thank you to those of you who've taken the time to fill out the survey!

That's still to be determined. I hate to be so vague, but we're mulling around several ideas and don't want to throw out any misdirection intentionally.

We've noticed an obvious correlation between start of injection timing and engine failures. If you have a minute, feel free to fill out the survey! The more information we have, the more accurate the conclusions can be.
