Not necessarily original as the OEM replacement part also has the cotter pin clamp. That said, failures have been reported in the past starting around 100K miles. That was 20 years or more ago. Those that claim that they have high mileage vehicles with the original PHH in good condition either have not examined it thoroughly or removed it to inspect internally/completely and most likely are not the original owner so they won't know for certain that it was never replaced. Now that the vehicles are 27 to 31 years old you have a ticking time bomb.If you still see factory cotter pin clamps on the hose, it's original and should be replaced.
Very true. Almost noted that someone could have replaced with oem clamps, just seems.... rare & unlikelyNot necessarily original as the OEM replacement part also has the cotter pin clamp.

\/"More pinion bearings. More birfields. More Ujoints. More AC compressors. More window motors. More PS hoses. More SRS ECMs. More O2 sensors. More TREs."
PHH failure can lead to head warpage. Not so much a problem with the other parts.
"Nowhere near the most expensive. If you are at all attuned to your vehicle they usually give warning before they let go completely."
Heads are fairly expensive and PHH can let go with no warning.
How long can one expect a PHH to last on a 28 year old vehicle? I have been looking through maintenance records from previous owner and not sure of part number and if it’s ever been replaced in the vehicles 133,000 mile journey?
