Cripes! Now the clearance is opening up. Both intakes were .002” wider after only 80 miles. I must be doing something wrong.
Yeah, I am checking them on a cold engine. I will run them for 50 miles and check again. I’m not too worried yet….I should add that I did just replace the rocker arm shafts as two of them appeared to have lost some small amount of plating. The new ones appear to be hardened.
Compare pushrods to each other, check the ends for looseness. Ring test to see if they sound the same, roll them on a piece of glass. If you replace them, get steel ones. Check the valves for stretching or receding.
Both of those would cause clearance to close up, not open up.
So much for feeling better…
