!!!!!!!!VERY IMPORTANT!!!!!!!
What is the most likely cause of less lift on one intake valve then all the rest. There is only one that is not lifting enough. It is the same cylinder that the rocker arm stud has pulled up before. Is it okay to drive???
ANy ideas Thanks Jason

It sounds like a "rolled" Lobe on the cam. You might check to see that the stud hasnt pulled again, or possibly a bent pushrod. Good luck.....Longhorn

It sounds like the cam lobe for that lifter is worn out. Unless the rocker is really loose, then the cam is worn. The engine will run for a long time with the lobe worn out. Afterwhile, the lobe will be worn round and the valve will not open. The engine will miss on that cylinder so you will lose power.

I would limit the driving to a minimum...like, moving it to cut the grass. If it is the stud getting pulled out, things can break and get metal chips in the oil. If it is a cam going flat, then you DO have metal shavings in the oil. |
