I need some advice.
Thanks

If your engine has an exhaust valve lash specification of .013”-.015” then see if a .016” feeler will slip in. If so adjustment is recommended but a little extra clearance won’t hurt and may actually benefit by allowing better valve contact with the seat to aid in cooling. Check the other end of the tolerance with a feeler .001” under the minimum too to be sure they aren’t too tight. If set accurately and tightened securely they should stay a year or longer.

The valve would tend to pound into the seat reducing lash. When they quit clicking was the signal to attend to them.

All my other cars have solid lifters too, except for my rotary! The honda is every 50k miles and the BMW is every 15k. I kind of enjoy it. I usually put the cars in 5th gear and just push to roll it over to the next lobe instead of trying to do it with the starter. If you pull the spark plugs its easy.
