Unfortunately these hydraulic lifters are known to collapse over time . We have replaced many lifters for this issue .We do them as a set because after one has failed the others usually fair not to far down the road .You can tell by just pushing on them and seeing which ones are bad and has no resistance .You will need to replace the hydraulic lifters to fix this issue .This is the next step . Hoped this helped.Positive feedback and bonuses greatly appreciated.
