Thank you. I will definitely discuss that repair with my mechanic.
What is the consensus though regarding whether my car will be damaged if I leave things as is (i.e., lifters have been replaced once, but ticking comes back rarely)? I've read conflicting opinions. Some people say my engine will be fine if this intermittent problem persists (including my mechanic), and other people say my engine could be harmed. Has a consensus been reached?
