Engine tapping sound
[ame="https://www.youtube.com/watch?v=JqgbFiToVoE"]Frs tapping sound - YouTube[/ame]
62k mile, no mods completely bone stock. The tapping sound is noticeable at 2000 rpm at the 0.20 mark. Side note the tapping occurs after warm up and noticeable when rpm comes up or down to 2000-3500 rpm. The tap is lightly noticeable during 4300-7000 rpm. I know it's hard to diagnose by video i would like to know what's your opinion on it. Ty |

Yep, either a lifter with too much space or something else in the valve train.
Do you track your car .. ?? How long has it been making that sound .. ?? Back-in-the-day ..... with a 9/16" wrench, a screwdriver and a feeler gauge, we could have quieted that puppy down ...... ![]() NOW. look at this mess .......and that's just half of it ...... ![]() humfrz |

What I would do is get me a long screwdriver and place it around the engine compartment (with the soft end up to your ear) and see if you can isolate where the sound is coming from. Then, I would take it into a dealer for an evaluation by their techs. Also, ask them if any necessary repair would be covered under warranty (it looks like you are close on that). As far as driving it making that tapping sound, IF IT IS AN OUT OF TOLERANCE LIFTER, it shouldn't hurt the car ...... it's just not opening that one valve as far as it should be opened. Keep us posted. Hopefully others will be along with some more insight. humfrz |

It was a different engine but that video sounds exactly like a wrist pin failure I had. That engine died a horrible death soon afterward.

Didn't someone on here have a bad vacuum pump that made a sound like the lifters? But I remember it being louder than the sound I am hearing in the video.
If you do find the cause, please post back!! |

Those have a bright/harsh intermittent knock but yes, I remember someone posted a good recording of it.
