Anybody had any lifter issues recently, on higher mileage cars? I know Ken had one back in ’06 but I can’t see anything else since.
I now a have a constant “ticking” noise that can be heard from outside the car when the engine is hot or cold, at idle.
The rate is around 3-4 TPS (Ticks Per Second) at idle when the engine is warm and is there all the time.
It is a metallic sound, and is directly linked to engine speed, but cannot be heard as the engine revs get higher.
It is NOT the oil valve piston (had that replaced twice, so I know it is not that noise) and is not radiator/exhaust/intake warming/cooling.
What I really want to know, is does everyone have this clicky noise or do I have to take it in to the dealer again?
The radiator fan was replaced last week, and at the time they said no other faults were showing on the PIWIS system.
Would a faulty lifter show up on a fault diagnosis? Am I just being paranoid?
Cheers
Jack

Your dealership may not perform some activities such as disabling safety equipment.
hmmmmmmmmmmmm, Jack... It does sound suspiciously like a non-inflated lifter... couple of questions before the paranoia sets in... Is the ambient temperature still pretty cold there? Are you using 0w-40w oil... and how loud is it?
If it's still very cold, you might get some mild lifter noise even if the motor is warmed up - but it still should go away in a few minutes of easy driving... if it can't be heard as the revs get higher, then it's probably ok. I don't think this is an official "fault" to be found by the PIWIS machine...

Brad, it is around 7C today. But I gave the car a good thrash home tonight and as I pulled up on the drive it was still doing it.
As for the volume, mmmm, how would you define it? If it was windy out, you wouldn't hear it. It is louder from OUR drivers side (your passenger). I need to have a really close listen in the morning after my commute, and see if it goes away at higher revs, or just gets drowned out.
Will it do any damage, or will it just not perform at full chat on the one cylinder?
The oil is and always has been Mobil 1 and is currently right on the full mark. It hasn't used ANY oil in the last 15,000 miles!!

44 F is not that cold, (compared to northern Alberta, for instance) but, still on the cold side of things... Make sure the Mobil 1 that's being used is 0w-40w - not 5w-40w or 10w-50w... your lack of oil use is impressive, so the motor is tight.. see if you can have someone else work the throttle while you listen to it outside the car to see if it persists as the revs go up and down... usually a non or partially inflated lifter is louder than you describe... it might also be an idler pulley losing its bearings - they can sound like that too when they go... Your only recourse might be to take it into the OPC and see what they say... if the lifter is not fully inflating with oil, they might be able to tell as far as the valve lift action goes and be able to spot it when they hook the car up to the big diagnostic computer (as opposed to the PIWIS machine)... if it is a lifter problem, I hope they might have some mercy, since the car is 60 days out of warranty... sheesh. I know they were not accommodating on the fan problem, but this is a much different kettle of fish...

Hmmm, mine has alway made a bit of tappet noise too, (2.7 engine) much along the lines that you describe, and more noticeable from the drvers side (UK) too. It does not seem to be particularly temperture senitive either, I hear it from cold, and also when the engine is hot after a good thrash. Nor is it consistent, it can vary.
I have run the problem thro the Personal Porsche Paranoia filter too, but have so far concluded that as the engine runs like a sweetie in every other respect, that's just the noise it makes.
Not sure I now want to re-run the PPP filter programme though!
Do these engines have hydraulic tappets? (I'm assuming they do)
I have done nothing but thrash my CS within an inch of it's life every time I take it out on the road/track/wherever.............. Now I begin to Worry.....
You have already had stuff changed, and still you have problems.......... Now you are out of warranty? Time to declare war on Porsche GB and demand an extension to our warranties, as the US have (even they pay less for ther cars).
i have the same problem on my CS too. On sunday i drove over 30 miles and the temp was around 70. The noise was still there.
I actually took my car to Beverly Hills Porsche Dealer to take a look or listen a couple months back. I was told it was normal to have lifters noise and i just have to live with it.
So far with all the rattling, clunks and problems, I am very close to regretting purchasing the car. I am wondering if this is a ploy from Porsche AG to put out an inferior entry level product so that customers will upgrade to a more expansive product.

Well, sort of... they have lifters that are "inflated" by the motor oil and is part of the extensive oiling system... the little holes that allow the oil to go in and "inflate" the lifters are very small, hence my question to Jack about using 0w-40w oil, which must be used so that the oil gets in there...
Some lifter noise is normal, which is also why I asked about how loud it was - trying to differentiate "just out of warranty paranoia" (no offense, Jack) from what's really going on

Most everything that's used on the more expensive models are used on these cars too so I don't think it's a ploy... the more expensive cars have their problems and foibles, too... if you're not satisfied with your dealer's response to the problems you've brought to them, try going to anther dealership - there's a lot of them in the LA area that wouldn't mind having your business.

I've also have the same problem - for almost 2 years. The sound is constant, very "lifterish" sounding, and entirely a function of engine rpm's. Took the CS to my dealership, and they said it was an exhaust leak on the right side of the engine. Since I have Fabspeed headers (supplied/installed by others), I took it to the tuning shop (who installed the headers) to get the header bolts tightened. Apparently they were NOT very loose and tightening made a slight, but minor improvement. Given that the engine works great otherwise, I just accepted the situation, but more and more I'm thinking that it's really a lifter problem. Since the CS is hibernating for the winter, it's been a couple of months since I've driven it, and it will be a couple more before it sees the light of day. Come spring I think I'll have to investigate the lifter issue further. REAL interested to see if others have the same or similar experiences ...
