To adjust, Loosen the locknut (10mm) and check clearance with a feeler guage. Clearance should be .006" (.15mm) for both, intake and exhaust valves. Turn the adjuster with a stubby flat blade screwdriver untill the proper clearance is achieved then tighten the locknut (5.8-7.2 ft. lbs) while holding the adjuster in place with the screwdriver.

Checking valve adjustment is a preventative maintenance procedure. Most of the time the valve clearances are within specifications when checked. Sometimes you'll find a loose one due to some wear in the valve train. Sometimes you'll find a tight one due to valve seat recession.The loose valves will produce some noise.

The exhaust valve will run hotter than the intake valve so you have more initial lash specified. That will be needed for times when the engine is run at full power. If you can’t idle the engine while checking clearance then it would be reasonable to heat the engine, shut it off, pull the valve cover and check clearances soon. Clearances too tight, on the other hand, can prevent the valves from completely closing (or not closing for a long enough period per cycle) and are more prone to heat damage and eventual valve failure. If in doubt, get them checked. Got questions for us? Ask them here!Plan about 10 hours to do the valve adjustment. Theres alot of crap that has to come off to get the valve covers off.

This clearance is called "lash." If the valve lash is set incorrectly (too much clearance, or not enough), the engine may respond by running rough at idle, particularly while warming up.Bottom line is that there are VERY FEW SYMPTOMS OF IMPROPER CLEARANCE.

I just adjusted mine the other day at 98k. About half of the exhaust valves were tight, and about half of the intake valves were loose- none bad enough to really cause a problem, but enough to be worth adjusting. You can calculate the expected total air leakage through your valve by summing the clearance leakage and displacement leakage estimated by your valve manufacturer. If your valve's air leakage is excessive, you'll notice symptoms such as a drop in material throughput or an increase in the conveying system's air requirement.
