rattles

I'd really appreciate some feedback from anyone that has had RMS problems, at what stage did you replace the seal, mine is not too bad at the moment so I am tempted to just keep monitoring it until it starts to drip on the garge floor.

<{POST_SNAPBACK}>

Hi Glenn, don't worry too much. I bought the car with RMS already diagnosed. Only after I had joined different forums I realized that this "little easy to fix leak" was a common Porsche problem. For the first 4 months I used to have one or two drops a month on the garage floor. Since it's gotten hotter I haven't seen any of it. Doesn't really make sense since with higher temps the oil should be able to bypass the seals easier - maybe I loose it on the Autobahn when I go 270+ :P

Anyway, if it doesn't get worse I'll just wait until the clutch is ready to be replaced and have it done then. Latest at the 80k inspection which is still 10k ahead. At least I'm determined not to let it ruin my fun with the car (as with the rattles).

Thanks Thorsten,

It's a while since I started this topic and since then it dos not appear to have become worse. I'm with you I plan to enjoy the car and fix it later if required. I took it to my local Porsche independant mechanic and he advised the same, said he has seen plenty much worse.

I also agree with Scouser, this is my last Porsche too, great car to drive but not enough care taken when they bolt them together especially for the price. A 997S is now A$240,000 here.

I can not say that I always agree with the FIA rules but in this case I think they did the right thing - the Michelin teams did not.

FIA Statement on USGP

Written by: Adam Cooper Indianapolis, Ind. – 6/20/2005 The following statement was released Monday morning by the FIA, Formula’ 1’s governing body, regarding the controversy at the U.S. Grand Prix that led to the withdrawal of the 14 Michelin-tired cars before the start:

"Formula 1 is a sporting contest. It must operate to clear rules. These cannot be negotiated each time a competitor brings the wrong equipment to a race.

At Indianapolis, we were told by Michelin that their tires would be unsafe unless their cars were slowed in the main corner. We understood and among other suggestions offered to help them by monitoring speeds and penalizing any excess. However, the Michelin teams refused to agree unless the Bridgestone runners were slowed by the same amount. They suggested a chicane.

The Michelin teams seemed unable to understand that this would have been grossly unfair as well as contrary to the rules. The Bridgestone teams had suitable tires. They did not need to slow down. The Michelin teams’ lack of speed through turn 13 would have been a direct result of inferior equipment, as often happens in Formula 1. It must also be remembered that the FIA wrote to all of the teams and both tire manufacturers on June 1, 2005, to emphasise that “tires should be built to be reliable under all circumstances” (see correspondence on www.fia.com).

A chicane would have forced all cars, including those with tires optimized for high-speed, to run on a circuit whose characteristics had changed fundamentally – from ultra-high speed (because of turn 13) to very slow and twisting. It would also have involved changing the circuit without following any of the modern safety procedures, possibly with implications for the cars and their brakes. It is not difficult to imagine the reaction of an American court had there been an accident (whatever its cause) with the FIA having to admit it had failed to follow its own rules and safety procedures.

The reason for this debacle is clear. Each team is allowed to bring two types of tire: one an on-the-limit potential race winner, the other a back-up which, although slower, is absolutely reliable. Apparently, none of the Michelin teams brought a back-up to Indianapolis. They subsequently announced they were flying in new tires from France but then claimed that these too were unsafe.

What about the American fans? What about Formula 1 fans world-wide? Rather than boycott the race, the Michelin teams should have agreed to run at reduced speed in turn 13. The rules would have been kept, they would have earned Championship points and the fans would have had a race. As it is, by refusing to run unless the FIA broke the rules and handicapped the Bridgestone runners, they have damaged themselves and the sport.

It should also be made clear that Formula One Management and Indianapolis Motor Speedway, as commercial entities, can have no role in the enforcement of the rules."

Regardless of who is at fault its the spectators who are the losers. Bernie will have still taken home his usual pocket money, Indy Motor Speedway certainly got paid for the tickets and I doubt that the Michelin teams will be giving back any of their sponsorship dollars.

Maybe those that did make money from the event and Michelin could work out a formula where 2005 ticket holders got free tickets for 2006. That wont help those who came from overseas or travelled long distances in the US but it may go part way to restoring some credibility with the fans and will have a secondary benefit of putting some people in the stands in 2006, doubt that there will be many paying customers.

Getting back to the subject I went to Indy in 2002 with my family, total cost including air tickets from Australia around $6000, the highlight, easy, Porsche Supercup and that race track.

Well, if you have a laptop computer I like Car-Code as it can give real time and recorded plots of MAF, O2 sensors, coolant temp, RPM, etc., etc. At $120 for the software and cable I have found it hard to beat.

I have a Davis CarChip EX that I am reviewing now. So far it looks like a good recorder (of up to three monitoring systems) but pretty limited as a diagnostic tool.

<{POST_SNAPBACK}>

Loren,

Did you need to buy any extra bits or just the standard unit with ISO gateway that they mention on the Car-Code website.

I'll visit the US next month and thought I might buy an OBD2 unit for my 99 996 C2 6 speed RHD

Any suggestions on which unit is the most suitable, best value, easiest to use would be appreciated. I will be using a laptop not PDA.

Is it best to buy online or from a retailler.

Thanks

<{POST_SNAPBACK}>

Check this one out - http://www.autoenginuity.com/ I have it and just used it on my 99 c4. I like the way it works, they give you free software upgrades, and ALWAYS respond to any questions you might have.

<{POST_SNAPBACK}>

Thanks for the info. on both units Autoenginuity is more that twice the price of Digimoto, both appear to cover most tests. Any reason why you went for the more expensive model

Loren...

How do I remove the cover that is in the picture without breaking the clips. I can feel it move but I'm not sure where its clipped.

Do you have a schematic?

<{POST_SNAPBACK}>

I've had that piece out, if you put your finger through the aperture and lever off the C panel with your thumb it should come out. Just apply gentle steady pressure.

<{POST_SNAPBACK}>

Rattles...

Are you saying remove the entire C panel or just the small cover.

thx...

Jim

<{POST_SNAPBACK}>

Jim,

Just the small cover. One of the clips that held my C panel in place was bent over and was making a lot of noise, I tried getting the C panel off using Loren's instructions but the last clip near the back window would not release, I just removed that small cover to access the bent clip.

Could you send me a copy too

Hi Thortsen,

Its your roof rattle mate from Australia, between us maybe we can do what Porsche finds impossible. We have both had similar problems, my roof is not too bad now. Try some silicone grease along the edge of the rubber seal that runs along the back of the sunroof when its open.

I am in China now so cant send you a picture but will do a PM when I get back next week, sounds like a similar problem to mine but it only happened when the roof was open.

Glenn

It is the one on the left, 2169.  The one on the right is the one sold by Porsche that I do not like.

Just to confuse you Hazet also has a 2169-1 but it is too big.

<{POST_SNAPBACK}>

Do you know of an online source for this item, I have tried searching but no luck so far.

thanks T.P.

Is there one particular model of Hazet oil filter wrench to suit 996's or does one size fit all

Thanks

type 8.5 liters to US quarts into your Google search and it will calculate it.

In the States, all the brands are almost exactly the same for each grade.  You can, however, have dirty tanks at a specific station, but, everything being equal, I don't believe you could measure much of a difference between non-racing fuel.  (93 octane and below)

Rattles:  your guy is not measuring performance with street gas, but is using a 98 octane which is more of a racing fuel.

<{POST_SNAPBACK}>

Must be different here, regular unleaded is 92 octane, premium is 95 or 98, all from the pumps at most gas stations.

He was comparing 98 Shell with 98 BP or Mobil.

The drivers manual for my 99 996 C2 says 98 Ron/ should be used, 95 can also be used but the knock sensors will adjust the timing. Maybe its different in US cars.

I also felt the same as you, most good brands are going to be very close, I'm sceptical when people say this ones better than that but he says his dyno tests show a difference. Theres nothing in it for him.

<{POST_SNAPBACK}>

Sorry...didn't see that you were not in the States. Isn't the octane rating over there calculated differently than here. I think you use the research octane (RON) rating and we use the motor rating (MON) 96 RON equals 92 MON.

<{POST_SNAPBACK}>

yes, its RON here 98 RON = 88 MON 95 RON = 85 MON

Had my car in for a small service yesterday at a local Porsche specialist [non dealer]. He asked which fuel I had been using because there were a couple of fuel related faults showing when he did the system tests. I have used Shell pretty much exclusively since I bought the car.

He also said that when he dyno tests cars he gets different results depending on which brand of gasoline [98 octane unleaded] is in the [same] car. His research shows that Mobil and BP are giving the best results and are burning cleaner. He does not sell gas. He prepares his own racing Porches so can get back to back tests on his own engines.

Anyone have any opinions re this.

As a 911 owner, I don't understand what Porsche is up to. The Boxster started around 210 bhp and now with the Cayman has 302 bhp. The 911 over the same time period went from 300bhp to 355bhp. So thats 50% boost versus 16%. The new Cayman looks a very fast car, too fast.

When Ferrari have gone from 385bhp to 489bhp, I don't see the 997 holding it's own. The new GT3 better make at least the 500 bhp plus if it's to stay with the 430 Stradale when it arrives. Looks like Ferrari finally put the electronics etc on their car also.

I don't understand the Cayman strategy. It sole purpose looks to undermine the resale for 996 owners given the Cayman is likely a faster and better handling car.

Anyone else got any opinions?

<{POST_SNAPBACK}>

I took a 997S for a four hour test drive yesterday, amazing. Try to do the same and let us know if you still feel disappointed, I would be interested to hear your comments.

Sure the Cayman will reduce resale values on the 996 and will take some sales from the 997S but that's progress. The positive side to that is that Porsche will have to lift the bar even further for the 998.

On the road here a new 997S costs around A$240,000, thats about US$185,000. Now THAT"S disappointing.

What the hell, if its still under warranty I'd get it done. Porsche can afford it

My OPC has just discovered that my RMC is leaking during a recent  service.

Its done 25000 miles and is only 22 months old. Will also get the clutch changed if it shows sign of wear as they'll have the gearbox out to do the RMS any.

<{POST_SNAPBACK}>

Its way out of warranty so I'll just see what happens. My reason for raising the question was to get an idea at what point the seal was being replaced in most cases.

Do not look under the car again and it won't effect you.  Many cars over time will show signs of oil biuldup.  It doesn't mean there is a leak.  Woory about it if you start loosing oil or see drops on the ground.

<{POST_SNAPBACK}>

I am sure you're right, my old 86 SAAB turbo leaks oil from places that aren't even supposed to contain oil but still goes like a bullet.

I'd really appreciate some feedback from anyone that has had RMS problems, at waht stage did you replace the seal, mine is not too bad at the moment so I am tempted to just keep monitoring it until it starts to drip on the garge floor.

I have just found what appears to be the first signs of an RMS leak on my 99c2, there are no spots of oil on the garage floor but the area where the engine and gearbox join has a greasy film covering a section about 2 inches by 4 inces. Looks like its been happening for a while as its a mixture of oil and road grime.

My car has done 19000 miles, I bought it new and it has not had any RMS work before.

Any suggestions on what to do now, its not dripping oil so do I just leave it until it gets worse or is the best course of action to get it replaced asap. The clutch is OK, no signs of slip.

Thanks for the replies, I was hoping there had been an upgrade for recent models that could be used or some way of wiring in an additional sound source.

The turn indicator sender on my 99 C2 is almost inaudible if the windows are down. Coupled with the very feint green turn arrows its easy to leave the indictor on when making a gradual left or right turn. Does anyone know of a fix for this problem.

Thanks

Hello,

I know people have voiced their opinions regarding ride quality on different tires.  My Pirelli tires are just about at the end of their life, and I've begun to look for new tires.  I wasn't too happy with the ride quality that I have received from my Pirelli's (very loud..too many rattles).  From what I've heard, the Contis, Michelin, and Yokos all provide better rides than those of the Pirelli.  I don't track my car much, and the roads in Chicago make for quite an uncomfortable ride.

Thanks!

Porsche Australia runs regular drive days for likely buyers, usually about 300 km on counrty roads, I guess you have them in the US too, I have been on two of them. They have 6 or 8 Carreras and Boxters and during the day you get to drive each car. Its a good way to compare the cars and the tyres.

I found that the Bridgestone tyres were the quietest, my 99 C2 came fitted with them, the model numebr is probably out of date now but they are SO2's

Good grip wet or dry, long mileage and quiet. Cant say what they are like in snow.

Love my car but I am really p------ off with the built in sound system.

<{POST_SNAPBACK}>

My buddy owns an Aston Martin Vanquish. He spent about 7000 EUR (~9200$) on the built in sound system which is made by Alpine as far as I know.

Anyway the sound sucks becauses the equalizer is a joke. A monitor based nav system ws not available by AM. So he spent another few grands to have a customized panel fit in together with amplifiers and a pioneer avix xc1.

Still I would trade in the car for my Porsche at any time :notworthy:

<{POST_SNAPBACK}>

The ''sound'' system is fine, its the built in Zuffenhausen Symphony coming from various parts of my car that I was referring too, I haven't had the window squeak that Toddels mentions but have had just about very other that has been raised on this forum by countless owners. I just wish they could raise the body build to the same level as the performance and handling.
