Lifter clacking - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My relatively fresh, rebuilt 327 seems to have a failed lifter. The engine probably only has 200 miles on and has been running flawlessly since break-in. I changed the oil right after break in and again at 100 or so miles. Used Brad Penn break-in oil.

Yesterday I noticed a ticking sound, thought maybe an exhaust leak but quickly heard a lifter clacking away. #2 cylinder and only that cylinder.

Wondering if I should change all the lifters or just that one?

Don’t want to do the work and then have another one go, but they were decent comp cam lifters so not sure .
