997 Rat damage
jroach replied to jroach's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)
saw this article: http://www.wsbtv.com/news/2-investigates/protect-your-car-rodents-eating-wires-in-newer-vehicles/242817925 I wonder if our cars use the soy based insulation. -
997 Rear bumper upgrade or not
jroach replied to jroach's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)
I'm afraid the mod on the back end will make the front end look out of place. Leaning towards keeping it the way it is but I still like the center exhaust of the GT's and wouldn't mind getting that look. Thanks to all for your opinions. -
I was hit yesterday, not hard but hard enough to break the bumperette and I can tell that the bumper is now uneven if you look at the exhaust tips (it's pushed in more on one side than the other). To fix it right I'm thinking the entire bumper, at a minimum, will need to be replaced. If the rear bumper is going to be replaced should I upgrade to a different type? I always liked the GT exhaust out the center and maybe I should look at turning this negative into a positive. I have read about many upgrades and I figure it is a matter of taste. Thoughts from members that are contemplating the same, have done it, or have a strong opinion would be appreciated.

Took the car in Weds and it was done Thurs. McKenna provided me a loaner (Panamera) and took care of everything! McKenna is several miles out of the way for me but it's worth the extra gas and time to get people who want to take care of you. I didn't replace the clutch...it had plenty of life left and seemed like a waste of money to replace it three years sooner (or maybe more) than it should be. My contribution to being green (smile). They did replace the seal for the Intermediate shaft on the transmission side as well as the RMS. Not certain if that was a normal procedure but my service manager said it wasn't unusual. We had talked about the IMS but didn't take any action to investigate...based on all the good input from this thread I didn't want to pursue something that is so hard to prove/find. I don't drive the car to extremes, it only has 25k miles, and those are pretty easy miles as well. My remedy is to just get the 991 when it comes out (smile). Thanks to all for the discussion!

JFP, In addition to coleta's question....Will the technician know what the tolerance or allowable 'wobble' allowed between the cams? Do you measure the variance at accel then again at decel? I'm not planning to crack the engine open at my cost. If Porsche is covering the RMS I'm thinking they might cover IMS but it would need to be defendable. When Porsche fixes IMS issues do they replace the case? In my situation I suspect I don't have an obvious failure if any at all so a bearing going bad might be difficult to prove. To replace the bearing with the LN version as a preventative measure might be costly and risk other problems later.
-
Once the transmission and engine have been separated to replace the RMS will a failing IMS be obvious? I take it in Weds and would like to know what is the process for checking the IMS. I can imagine that when the IMS completely goes that it is obvious. I'm looking more for a litmus test that says it is "about to go" or has good odds that it "will go". Thoughts appreciated.
-
Maurice, (and all).... Thanks for the advice. Good news! Porsche approved the RMS replacement. Will they be able to tell once they break the trans from the engine if this is an RMS vs IMS failure? If so, I will alert them to do so. I'm concerned as why an engine, driven light to moderate, would have such a failure at 25k miles. I'm hoping it is a lack of use that has caused the RMS to go bad. The car will sit for several weeks at a time. If it is an IMS failure, what is the best remedy? If I have a MY07, does this mean I have the larger IMS bearing already? I will evaluate clutch replacement/TO bearing after they get it apart (unless this group is suggesting replace them anyway). These will be on my dime if I decide to replace them. Thoughts?
-
I don't think the transmission was removed. I have read about the IMS problem being more prevalent in the MY05/06 or older. Are there any other symptoms besides oil leak at the eng/tran mount? If my case is approved should I pay to have the IMS bearing replaced? Also, is replacing the clutch disk a preventative measure? I like the idea.
-
I took my 07 997 in for regular scheduled maintenance. Technician found that the RMS was leaking. I am 10 days out of warranty. Only 25k miles and always serviced by Porsche. I have opened a customer assist case with Porsche. Any idea on my chances of getting this covered or your personal experiences?
-
Skizot, WHat is the purpose of the indention? For the Whistle?
-
Thanks dphatch! I suspect you are correct with the thought that it was there to strengthen the hood. I'm also thinking it might have the inverse effect but I need to gather more examples. Could it be from hi-speed pressure pushing against that area???? I have to say that I am not a fast driver so I don't see how on rare occasional my 90mph (maybe a little more) would have this effect but throwing it into the possible causes.
-
Mine looks the same. Great picture by the way. I didn't think you'd be able to actually get a picture of it given how difficult the effect is to see with the naked eye. One more thought. My hood has clear bra on it. Given the pressure necessary to remove all the air bubbles from the material during application is it possible, going on the premise that the AL hood is somewhat fragile, that during this process the metal was flattened out ? This is really a stretch though as the application of pressure would be applied to the entire section having the clear bra applied as well as the sections adjacent to it where the flat edged plastic tool runs off the material onto the hood during the install process. Those sections of the hood show no signs of any flattening at all and given the clear demarcation area where it starts and stops the metal would have to significantly weaker in this area than anywhere else on the hood. Only thing that makes sense is that is was a deliberate factory design. Why ? Can't say outside of the whistling hood theory. I don't have the clear bra but your explanation (pressure to remove air bubbles out) makes sense. Can I bother you to look under the hood at the front under the supporting structure to see if you have any material bonded/laminated to the skin? I haven't had the time to swing by my local dealer in Pasadena but will try and get by next week.
-
I never felt comfortable with closing it per the directions so I have always used the front edge (finger and thumb) against the leading edge where the metal is rolled over with just enough pressure until you hear the click. The porsche before this one seemed more difficult to close (1998) and I became more aware of it at that time. Maybe that is why I have the indent (smile). Either way if the average Porsche owner is anything like me then the front luggage area isn't used that often...I'm guessing I might have used the area 3 to 4 times. I open and close it more for detailing the car, maybe once every quarter or so. I'm going to the dealer today to ask what they think. My guess is they will say it is an owner problem.
-
Actually at almost every angle you can't see it. I don't think I'll have it fixed. More interested in finding out why or what. Also, I have had good results with Dent Pro as well.
-
phillipj, could I bother you to take a look at the underside of the hood and describe if you have any material bonded to the hood in this area (under the support structure, bonded to the skin of the hood itself). Yes, I'll be taking it to the dealer when the next oil change is due but I'm not certain I would have them do anything. Repaint or bodywork doesn't sound like a path I want to go down. It's more of a curiosity factor.
-
The picture doesn't show how even the indent is across the entire hood but the last inch or so on either side. Interesting thing is now that I know what to look for I'm seeing quite a few. I'm going to stop by the dealer and look at new cars to see if they have the same issue. I looked on the inside of the hood and noticed a piece of rough almost fabric like but maybe metal material that follows the same outline. You have to get your head far enough back so you can look back towards the front. Looking through the holes you can see this material/fabric I mention. The fabric seems to be the same outline as the indentation. Possible reasons for the indent: Designed this way to reduce the whistle noise (as mentioned by dphatch in this post) Caused from pushing the hood closed Optical illusion caused in the paint Something to do with this fabric stuck to the inside of the hood (ie: in applying the fabric it causes the hood to change its shape. It was like that from the beginning and maybe a defective part Any other possibilities?
-
It took me awhile to find the right position and lighting to see the indentation. I had practically given up until I went outside this morning and saw it more clearly with the Sun towards the back shining forward across the hood (its that slight of an indentation. Tell me what you think?
-
I have always closed my hoods using the very edge where the metal is rolled over (1st 1/2 inch). If your indentation is like mine then I don't think it is caused by using your palms. It is too even and too wide. If it is then Porsche has a design problem (smile).
-
I had thought the same thing about the straight edge and tried it when I first noticed the indent. My hoods curve starts from the leading edge and continues back for some way Feet not inches). My indentation is not exaggerated enough that it goes the opposite direction of the curve but maybe more like the curve changing slightly. I'm not certain about the transition theory since it doesn't explain the two inches on either side. The upper line of the indentation runs through the upper part of the hood crest. My car is silver with about 20k mi. I hope to have the camera back on Thurs so I'll post pics then. I have scanned through dozens of 997 pics for sale and can't find the indentation but it is so slight that I'm wondering if it has to do with the color/metalic and how it was painted (ie:more of an optical illusion).
-
I can't get a good pic using my camera phone. I will need to wait until my digital camera comes back (a few weeks). The indentation is at the front edge of the front hood: It starts about one inch behind the leading edge for about 3 to 4 inches back and across the entire hood with the same margin on the sides. It is very slight and symmetrical. I can almost buy the anti whistling item but like you I don't remember it on my previous porsche (1998).
-
I was looking at the 997 the other day and noticed what I thought was an indentation at the front of the hood. I can only see it at certain angles. It's about 3" wide and runs across the entire leading edge of the hood. I have had Porsches before and know how to close the trunk. I did a search but could find anybody else. Under warranty so I'm not that concerned but curious if others see the same.
-
Mike replaced the IPD part and O-ring at the same time. I can't be 100% certain but I would say it was the O-ring. Since the O-ring is so much cheaper I would start there. The IPD part is aluminum (stock is plastic) so I don't see how the IPD fitting could lose its shape. It might be that when the IPD part was originally installed or when the dealer has done work in that area that they didn't replace the O-ring.
-
In summary the work order from the dealer stated: Description Bin Amount ------------------- ------- --------- Distributor tube Test $95.66 The dealer did not fix it....they just identified the area (and that was ok). Mike at IPD diagnosed it the rest of the way and fixed it (no charge). I'm not certain what the o-ring cost would be but I would think less than $10.
-
Leak was at the smaller hose that comes from the air box up to the plenum. It clips on to the side of the plenum and has an O-ring. I think just replacing the O-ring the noise would have gone away. I was told that the plenum pressure around 2500 RPM's is at its highest.

Thanks george996 for the idea. It turned out to be a vacuum leak.
