Lifter chipped on 8BA

[Chuck41]

Hey all,

Hard to believe this is my first post. I can’t count the times when the expertise on here has saved my bacon over the 3 years I’ve had this car.

41 Ford with a 49 8BA engine and adjustable lifters. I needed to inspect and adjust the valves because the engine had developed a tapping when cold that seemed to be coming from the right front of the engine. Sure enough, the No. 5 intake valve had about double the spec on the clearance. Three others just needed a slight tweak and the rest were good.

The problem is that when I put force on the adjuster, my homemade lifter holding tool chipped out the top edge of the lifter at one of the holes. Of course I let it happen twice, so now I have two with a chip. Once I realized how my tool was causing this, I fixed it and the rest went great.

Obviously this is not good, but it does not seem like the lifter is structurally compromised. Would you run with this? What do you think the risks are? Not really wanting to pull the head right now.

Thanks,
Chuck
