We might miss the cacophony of mechanical sounds one day. Maybe they’ll be a 4.0L app you can plug into your 718 GTE in the year 2035 to similar the sound of the old 4.0 😂

That's a future I could not care less for.

Besides they would rather have you drive a fully virtual car in a "metaverse". Knowing those ****ing mad green terrorists they will keep ****ing you over there as well - they will still have an issue with you driving a virtual ICE car...

UncleDude

You might have some anger issues LOL

Bob Z.

Or too much Fox News.

Seriously though, I have never really heard the engine ticking noises others are hearing, but then again I have a pretty wide-open exhaust. Even with that, I do not hear it when it at idle.

YTownSpyder

I agree Bob. I thought maybe I wasn’t paying attention but last time out I couldn’t locate the ticking.

Hey everyone, update from the dealer.

They said they dont get enough cars to diagnose (Canada eh?) anyways the technician said it could be the valve lifters , recommends putting a few thousand KM and change oil to see how it is. He will also cross reference any other spydergt4 that comes into the dealership. Also gave him the link to this thread.

I find it weird because there was NO SOUNDS when I got the car and it drove perfect no weird noises. Only after 90KM on the odometer this annoying sound came up. For reference porsche had to recall all the 4.0 before 2022 for rod and camshaft issues that could cause engine fires. Which is why I am worried about this noise. Also, not plesant to drive a 100k plus car with this sound, many others ask me if that sound was normal. I think not. What are your opinions thoughts on this?

TXshaggy

The bold is incorrect. The recall involved a discrete number of 4.0 cars with known VINs where the conrod didn’t meet specification. Very few made it to customers and there were no fires.

The car makes lots of clicking and clacking racket, it’s normal.

jmartpr

This...if I remember correctly, it involved some VINs with cars manufactured between Dec 2020 and February 2021.
I no longer have my 718 GT4 but the 718 made the ticking noise right off the dealer.
Next day at was at the dealer complaining...nothing ever got fixed and had to live with it.
Put about 7K miles on the car including several track days, performance was great, the same can't be said about the engine and exhaust sound.
I think this noise is part of the design of the 9A2 engine and there's nothing you can do about it.

Interesting what @Rick DeMan said in this thread:

https://rennlist.com/forums/gt4-spyd...lerations.html


“A few years ago we chased a ticking sound for weeks in a 991 DFI engine, thought it was internal and checked every possibility.... Nothing...

Then we discovered it was the High Pressure Fuel Pump!!! Yes, that pump does exactly what you are describing and sounds like a lifter/chain/ticking/knocking.

New pump and problem solved. Has happened a few times since with other cars and we knew exactly what to look for.

Hey SPYDERJAILA,

a really unsatisfying reaction of your dealer !

At least an endoscopic inspection of the combustion chambers should be expected, to exclude (or verify)

-> piston contacting a valve
-> cylinder bore scoring
-> glow ignitions in one cylinder
-> unsufficient screwed spark plug

That can be done through the spark plug bores without removal of the engine.

Moreover, I cannot understand that obviously none of the technical services did do an appropriate diagnostic of the widespread tick once per camshaft revolution to contribute the ticking to the generating components by :

-> recording the ticking synchronous with the rotational position of the camshaft (to be picked up fom the engines Hall - Sensor or from the ignition of any spark plug).
-> compare the frequency of the ticking to the natural frequencies of the different engine parts (should be known at Porsche).

This diagnostic is reliable, non invasive, done within a few minutes and doesn't need big equipment.

It is not the car that makes lots of clicking and clacking racket, it is just one or two parts of the engine - easy to determine, but could be not as easy to be fixed.

SPYDERJAILA

Here is the reference, there were no fires yes. They recalled them before anything happened, which is great on Porsche`s end.

Another update, the sound was gone after I gave the engine more revs, gas pedal all the way down limit to 4000 RPM. This was when the engine had 550 KM. Was finally able to enjoy the car properly which was glorious as I could finally hear the exhaust only without the loud obnoxious noises. This lasted for about 2-3 stoplights then the loud fluttering noise came back. After the long drive when I stopped the car to put the top back on, there was a lot of white smoke from the side intake vents, smelled like burning oil though didn`t seem serious as it was more of a foggy smoke not the thick hazy kind. I topped off the oil prior to driving with the Mobil 1 0w-40 the dealer provided me with. Will update again if noises stops again or gets louder.

The sound is like a metal flap scraping against another metal surface, I posted sound clips already not sure if the noise can be heard clearly but it is VERY loud, not normal for sure.

Also, dealer called me today and asked me to bring the car back in for a secondary opinion, also leave the car there for a few days to coordinate with Porsche Canada to see what is going on with this noise.

I've been trolling the forums here (and over at 718forum) for evidence of someone else with the same kind of metallic "fluttering" as you put it (great description btw, I was struggling with how to describe it) and I created an account just to say that I too have that same flutter! Mine is not nearly as pronounced as yours (yet), but it is definitely there and clearly heard with the windows down while driving by concrete walls or anything else that's good at bouncing sound back at the car. It has only developed within the last 200 miles or so (~1100 mi total) and gives me the feeling that something is for sure not right, to the point that I've become hesitant to drive it much recently. And I'm confident it's different from the other more common ticking sound that most people claim to have (caused by the injectors/fuel pump/definitely-not-those-things-and-something-else/whatever) because I have that too and it's been there since the day I took delivery. That ticking is "normal" to me; this new fluttering is not.

Please keep us all posted about your investigations and whatnot with the dealership, I for one am very interested in what they find and have to say about it.

I wonder if the oil is the issue? I was topping my oil up with 5w40 C40 as I couldn't find the 0w40 C40. The ticking didn't seem too bad... but I've since found 0w40 C40 and added about half a quart and the ticking is more noticeable now. I can't see a half quart of oil changing it but who knows?

Do you drive your car regularly, or let it sit for a few days at a time? I noticed issue on my 981 over a year ago...experienced the noise, and it then going away during drive after it sitting during the week, as I've been driving the car less and less during my ownership:
