Model T Ford Forum: Forum 2015: Valve Adj. Frequency?

I'M kinda wondering if there's a consensus on the frequency for adjusting valves. Here's the scenario: have newly rebuilt engine, z-head, new valves and adjustable tappets, new crank, new pistons, Stipe cam, etc. I have approximately 300 miles on the engine. So far, so good. I do get a little expected tappet noise at start up and less once the engine is warmed up. But I am wondering at what point should I be expecting to adjust the valve clearance and then how often I should do that.

Maybe 20,000 miles? If you keep the oil clean it should be a long, long time before you need to think about valve adjustment. Typically there should be no reason to adjust them unless you grind the valves during a valve job.

Did you replace the bearings when you installed the cam? If you placed a new cam and new bearings, and adjusted according to directions from the manufacturer My stipe cam said .010. If you think there is too much noise, you can check them again. If they are still adjusted as according to instructions, leave them alone. You may never need to re adjust unless you grind the valves.

With valves a little noise is not bad, but no noise could be too tight resulting in burnt valves.

Note. You must make the adjustment at the heel of the cam. If you adjust them at other cam position, you might not have the right clearance.

Norm, Everything was new in the engine except the block itself...and NOT rebuilt by me. I paid a well known professional outfit to do it. Some things aren't worth pinching pennies on.

Kevin,
It has been 10 years since I installed a Stipe 280 cam and have not needed to re-adjust the valves. The cam bearing were used.....everything else in the valve train was new including hard seats. I agree with Royce's comments

Thanks for the feedback. Nice to know I can just drive and enjoy. I'm ready for summer and hitting the road.
