Manufacturer summary

Original wording in English

This article supersedes TSB 25-2200 to update the parts list to add the new camshaft and tappet service kit and add F-650/F-750. Some of the vehicles listed in the Model statement above may exhibit an upper engine ticking or tapping noise at idle. Customers may also report experiencing rough engine performance, engine misfire, or a malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0301-P0308 in the powertrain control module (PCM). This may be due to camshaft and/or valve tappet having excess wear within the engine assembly.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
