Which SUBARU engines are interference? What SUBARU engines are non-interference?

Here is a table listing SUBARU engines, models, and years and which SUBARU engines are interference and which are non-interference.

This table refers to USDM (United States Domestic Market) SUBARU's. 

The SUBARU engine interference/non-interference chart above is available for download as an Excel 2007 spreadsheet here: SUBARU-engines-interference.xlsx

If the table/chart of SUBARU interference and SUBARU non-interference engines does not display properly in your browser, you can view the SUBARU interference/non-inteference engines list it as an image here.

This table aims to be as accurate as possible, but there are no guarantees.  Especially around model change years - sometimes in model change years early models of that year get some of the previous year's parts.

The SUBARU H6 6-cylinder 3.0L EZ30 engine is shown in the list above.  It has a timing chain with no set replacement interval; it is intended to last the lifetime of the engine.

Every SUBARU owner should know if their SUBARU's engines are interference or non-interference.  If the timing belt or timing chain breaks or jumps timing, it can cause bent valves and possibly dinged pistons in the engine, thus resulting in expensive repairs.

If you have a question or comment, or would like a specific engine added to the list, please post below, or visit the SUBARU forum.
