Valve Clearance Inspection - 5yrs but only 300hrs ??

[ty_thomas]

My '08 F250B has been in service since April of '10 but only has 300 hrs on it. The maintenance schedule says 500hrs or 5yrs, whichever comes first. Wear on these parts is only affected by the run time, any reason to do it now?

Maybe one of the Yammy gurus can offer an opinion. Thanks!

If the engine sounds and runs good, I probably would not do it. Just my .02

takes about 2 hours to check lash, maybe less.
takes about 16 hours to repair the damage caused by a tight ex valve.
plus about 1500 a head for the valve job.
keep looking and you will see its also time to replace the timing belt.

if the belt breaks it takes about 20 hours and about 11,000 dollars worth of parts to fix it.

your call.
