Valve Clearance Check Interval

[Gohn 68]

its getting up around 20,000 kms since I refurbed my XUD7TD cylinder head

everythings going good but I couldn't find any specific intervals suggested in the book to check the valve clearances

 

should I be checking them every 10, 20 or 50,000km or do you wait until it sounds like it needs it ?

 

thanks

I think every 200 000km is enough.

the wording from the Haynes manual is ' Checking should not need to be a routine operation'      'it should only be necessary when the valve gear becomes noisy, after engine overhaul, or when trying to trace cause of power loss'

 

so yeah, leave it alone!

 

given the amount of work required to adjust them, especially on a diesel, I wouldn't bother checking them until a belt change interval,   which is 72k miles or 120k km, or 5 years.

 

good oil and frequent changes will make them last longer, keeping the carbon levels in the oil down.
