There are enough threads on this and other forums dealing with retrofitting the IMS bearing but precious little on what action people are taking or have taken to maintain the larger, stronger non-retrofit bearing in the MY 05-08 cars.

Personally, I have adopted LN's recommendations and installed a magnetized oil drain plug; I maintain my revs. above 2,500; ensure that the oil level NEVER goes below the first bar; I avoid short trips; I change the oil (Motul 5W40) and filter every 5k miles; and I open up the filter, spread it and run a magnet across it. In addition, I always have the oil analyzed by Blackstone Labs.   

When and if the IMS Guardian comes out for the 997 ( including a matching dash button) I will certainly instal that.

I am now contemplating performing LN's only major preventive maintenance recommendation on these cars which is to pull the seal on the IMS bearing so that it can be lubricated by motor oil rather than relying in the sealed grease. But first I thought that I should ask this forum whether anybody has ever done this with success. Please weigh in with your experience and, for that matter, anything else that would be beneficial. Cheers.....

My buzzing-rattle came from the center crono gage and it stops when I turn it slightly off-center towards either side "between the stops". So guess in what position it's alway in? Hope this helps. Cheers...".

Oscar, no intention to highjack your thread but I have to ask Phillip whether his RE-11's are noisy.

I would think twice about Michelin Pilot SS. I bought a set for my 997.1 in May 2011 and have driven 35,000 km (22,000 miles) on them, all highway, no in-town driving and no track. I have suffered through a persistent loud howl between 113 and 118 kph since new with no change when I rotate them. I put my winters on and there is no howling. Now the rear Pilots are almost worn and the are scary in the rain. Not a happy camper. I am now looking for alternatives-sadly not many good ones out there from what I gather from Tire Rack.

I was just going to clean up some debris that was stuck around the mud flap at leading edge of the rear wheel well.

I jacked the rear up and removed the wheel to give me some more elbow room. As the mud flap it attached in part to the inner fender lining, I thought that I should have a look behind it to see what Porsche might have hidden behind the lining. Surprise, surprise!!

Eight pounds of wet sand and gravel. The other side had a little less.

All the fastening clips were rusty to some degree, the worst being the clip fused to the mud flap.

Body is still unmarked with only a small rust stain from the offending clip. Cleaned everything up, painted the lower part of the inner fender with gravel guard, and painted all the clips with anti rust paint to prolong their inevitable replacement.

A worthy note is that this whole area of the car is going to be a rust problem in years to come for those who do not periodically clean out this cavity- no way for the sand, gravel and water to get out once it gets past the upper lip of the lining. I weighed the gravel for fun- car is now 15 lbs. lighter.

I am going to check out the front soon.

Ditto with my car. Dealer changed expansion valve while on warranty but sound soon came back. Problem never really solved despite numerous attempts. Now I just live with it. I only notice when temperature is about 15 deg Celsius down. In hotter weather i do not hear it. Do post if you solve the issue.

BTW, wired to cut power is not a good idea for safety reasons. It may be tripped accidentally while car is moving with somebody legitimate in the car. However, if you want to, then put a battery cut-off relay at battery but be prepared to have car towed to Porsche dealer after being tripped to reset computer.

Attach to inside of front fender behind headlight. Use tool in toolkit to remove headlight carefully. Use some body gumbo to stick to fender. Wire directly into battery nearby. You can also install it behind the front bumper if the unit does not work under metal. Search this forum on how to remove bumper.

I always carry a tubeless tire repair kit, latex gloves and a throw away monkey suit. Already saved my backon while vacationing on the eastern seabord where I picked up a spike. Plug is still holding after 2 years. Have now also installed after market pressure sensors. Not much else that you can do if you want to maintain valuable trunk space. M2CW.

Thanks guys. In summary, a M97 3.8 water pump is different from a M97 3.6 and all M96. Right?

Interesting. Logray, from what you say, I'll stick with plastic.

Did a little more digging. Pelican has the the same part number for the M96 and M97 save that the suffix is 996 and 997, respectively. However, the 997 water pump is $50 cheaper. Now, that's a break.

Local Porsche dealer here is Canada now tells me that the pumps are "similar" (and for once they are competitive with Palican).

Are we to surmise that the M96 and M97 part numbers are interchangeable? If so, M96 owners should take note.

Thanks Loren. A follow up question. I just finished reading the Excellence Magazine tech article on the M96 plastic water pump impeller issue. Does the M97 motor not use the same type of plastic impeller and, if so, is it not prone to the same type of premature disintegration?

I have a 2006 C2S. Is the engine on my car referred to as an M96 or M97?

Thanks in advance.

Cheers.

Thanks to this thread I too solved my right side fan issue. Just some gravel stuck in the fan. Works fine now. Sure pays to participate....cheers to all.

I just posted and then realized I had not read your last post. Dahhh! I am a newbie to these forums....."

Joel, I got the same problem with my right cooling fan so do update us on your findings.

Cheers,

Thanks Guys for your input.

Unfortunately I was 750 miles away from home when it happened without my tools so I had to use the closest Porsche dealership. Changed all six. Bloody expensive but at least I could enjoy the drive home.

Cheers,

Hi, I am new to this forum and cannot find an answer to my problem. I have a 2006 997.1 C2S and at 50,000 miles my coil pack on #1 cylinder packed it in. Car is 10 weeks past the 6 year Porsche Approved Warranty. I was advised to replace all 6. Is this a premature failure? Thanks in Advance. Uwon
