Hi I have noticed when engine is hot (only when warmed up to working temperature, coming from a drive or idling until fans come on), it has this slight tap/knock sound... Sounds like a lazy lifter to me, what do you all think? Engine oil has been changed twice this year, car is at 21k miles . I ran Mobil 1 0w-40 and currently running Amsoil 5w-40, fresh oil (under 200 miles), changed last month. Last time I did an oil analysis it came out good, no wear metals out of the ordinary. It was sometime in the spring. Oil pressure has always been good, before and after I changed my oil pump... Never dropped under second line, never had a red pressure light. Should I be concerned? If you listen you can hear it next to injectors noise (the clicking). Until it warms up there is none. https://youtube.com/shorts/YwT8BHMRn_g Thank you for any feedback.
Stock 2nd generation headers.. replaced by previous owner some time back. Just checked my paper work.. work was done in 2013, at 8016 miles. Do they really sound like a tap noise when hot ?
I hear fuel injectors and either piston slap or slight detonation knock .. maybe I am not catching what you are referring to Sent from my moto g power using Tapatalk
I hear a drop in RPM part way through the clip, but other than that nothing untoward coming through on my Tannoys
I am almost confident it is not rod knock, the frequency is higher than the rod knock, it is at every piston revolution coming up or down.... @flash32, should I be concerned ? I might warm her up again and listen with a long tool and see if I can pinpoint more accurately. It kinda points to the left bank, but hard to tell. Definitely not headers sound, engine internal.
I know this isn’t a Jeep, but cracked manifolds are common on TJ’s. Symptoms are the same. Sounds like a lifter tick but goes away when warm. Basically a crack that closes up as the metal heats up.
I thought he said it was the opposite. The noise is there when warm or I would have thought the same thing. Mark II headers can still crack, plus I recently noticed Ferrari also changed the Cats when the Mark II was introduced so maybe their “fix” to prevent cracking required both changes.

Yes, no noise when cold. Starts slowly when the engine gets to operating temperature, i.e. when you can't put your hand anymore on oil cap, a couple of lines over the 120 minimum mark on gauge.
And you are sure that there wasn't any damage from the 2 times your oil pump was rebuilt and then replaced with a new one? To confirm, you did send the oil out pre-oil-pump replacement and post replacement, with some miles on the oil for analysis?
I have no way to know what happened when the first oil pump was reconditioned... that was 6 years ago.. not in my possession. but in documentation they said "oil leaks" so I doubt it was catastrophic. When it failed on me, engine was shut down before any oil pressure loss was recorded on dash.. but how would I know. I did an oil analysis before oil pump seal failed, in March this year, and it was fine (2000 miles old oil). Thanks
OK, so good sign... before the last issue the oil looked good. With 2k miles on the car since the change of the pump, post track incident, you should send the oil out. That is enough mileage for them to see something if this noise when warm is a new occurrence. I would also see if someone local with a 430 can swing by and you could compare when the temp is the same, that would also be helpful.
Pull the coils and look for burn marks where they fit the plugs, a bad connection on an old style plug cap can sound similar
I past the 70 mark this summer, definitely slowing down , the corners are coming up quicker while i am doing 30 mph
Update: I drove it to the Ferrari shop here and they listened and listened, and they are of an impression that it cannot be a engine component failure. If you listen for longer times, it comes and goes, or it becomes so weak that you can't distinguish from injectors ticking. My video is sort of a worse case scenario. It could well be a piston slap as @flash32 said, due to maybe carbon deposits or filthy injectors.. I thought I'd have someone else have a poke at it than me, as I never really listened another Ferrari engine at hot, let alone another F430. They wanted to do a full cold-warm idle run, so I left it with them... They said that sometimes internal headers failure CAN manifest at noises when hot only, when they expand, so it will checked for that. . Thanks all for feedback, let's hope nothing is very wrong. I can live if it's just a noisy engine or headers need changed (I might just go with new OEM challenge).
I haven't done that since 2008 or so with my E46 M3; and when I did an oil analysis they found a lot of dilution and that cleaner in the oil. So I suggest everyone doing so, follow up with an oil change; but it is a good idea.
Well, car spent 1/2 day on the hoist at Autohaus , and they took all covers off and listened to the engine. It seems that all noises are normal. There was a hose rubbing and vibrating when getting hot on the lower plastic cover, which contributed to the sound I heard.... I listened to the engine again and it all sounds normal. All well when it ends well ; ocd in full swing here
