14 GT500 Tapping noise under car??

[BelminZ]

Hey man! I sent you a PM

*UPDATE*

I picked up the car last night and it seems its all fixed now the Noise is gone. We replaced all 8 intake Hydraulic lashers and 8 Exhaust on the drivers side. So my assumption from Day 1 was the culprit. I'm assuming when hot the lasher started to fail. When cold he said they all felt firm when he pulled them. We did 3 tests, the first was getting the car up to temp and running it normal, it was fine. Second one was getting the car up to temp and running it hard to 6k RPMS and it was quiet, also 90 degree heat. Third test was me going home 40 minutes normal driving and some spirited driving, car was quiet.

I also noticed it seemed like the car didn't "pop" as much out the exhaust when letting off the throttle , it seemed smoother. maybe its just me.

is the noise still completely gone? Curious because I have the same noise.

So far it’s still gone , 500 miles later.

Not yet. I think it’s a Driver side exhaust Lash adjuster, being I'm hearing the noise resonate from the exhaust. I’d attempt to change out the lifter myself but I’m a little nervous . It’s suppose to go in the shop this Friday to be done, hopefully that’s it. Unless i get enough courage and do it myself , also no one lives around me to give me a Hand that KNOWS what there doing or I would ripped it apart by now.

My 2012 gt500 makes same noise what did you do to fix it thanks

He replaced the 32 lash adjusters, that fix seems to work most of the time.

Not that I'm aware of, and again, this may not fix it, but guys have replaced the lifters/lash adjusters and the noise has gone away. And it's a somewhat common issue. If you do replace them, let the lifters soak in oil for 24 hours or if you can heat the oil up to 150 to 180 degrees, you want to try and get all the air bubbles out of the lifters. I'm assuming you're running the FL-820S oil filter and Motorcraft 5W50 oil?

Yeah I didn't have the car on the lift but that was the driver side CAT When I took that recording. Cats seems fine aswell, I was hoping that was it.

Did you ever figure out what this Noise was.

 

[LS WUT]

Did you ever figure out what this Noise was? I have the same exact Noise coming from my 2013 GT500 with 9K Original Miles, OEM Oil Filter and MotorCraft 5W-50 Oil. Car runs, Sounds and feels great but when it warms up to Normal operation temps, you can hear that annoying tick underneath, especially when entering my Garage, it bounces off the walls like you mentioned.

He said what the problem was in post #56.. but I’ll post it for you.


*UPDATE*

I picked up the car last night and it seems its all fixed now the Noise is gone. We replaced all 8 intake Hydraulic lashers and 8 Exhaust on the drivers side. So my assumption from Day 1 was the culprit. I'm assuming when hot the lasher started to fail. When cold he said they all felt firm when he pulled them.
