I'll pull the rocker cover and check the springs & rocker arms. If they look OK and no evidence of metal filings, I will probably need to pull the intake and check the lifters.
Your issue will be obvious. Even with a collapsed lifter, one will be loose. Everything will not be OK. Look for metal like D.PASSMORE says.
