Just purchased 2001 C4 Cab

Well finally bit the bullet and found a nice C4 Cab with 94k on it. It has a great maintenance history as far as basic stuff but never had nor needed anything more. As this car is meant to be and will be driven what should be done to it? Working on Porsche�s is not a problem but familiarity of 996 is not the strong point, mainly worked on Cayenne�s. Any help with the list would be appreciated. Will Do: (What brands should be used) Oil Change, cut filter apart to check for particles � Mobil 1 0w-40 or Castrol 5w-50 Oil Filter - Mahle Plugs � Beru, Bosch, or? Air Filter � Mahle Cabin Air Filter - Mann Bleed brakes (pads / rotors are good) - ATE TYP200 Belt (do the tensioner and idler pulleys need done also) - Continental Fuel Filter - Mahle Transmission fluid - Mobil 1 Delvac 75w-90 Diff Fluid - Mobil 1 Delvac 75w-90 Not sure about : Water Pump, if so which brand? Coolant Change Power Steering Fluid Flush Help: IMS, should be done or just watched. Also what else would you do if you are doing this? RMS? Clutch? (Brand � Sachs? OEM?, LUK?) AOS? Other? Thanks

I just bought an 03 C2 and researched quite a few things.. a couple pointers: - IMS: I spent 3.5k to get the oil-fed plain bearing installed, but that was to replace the weakest of 911 bearings (single row 02-04). Ims solution if you have a single row bearing. You can get a stronger bearing from LN or similar for less, though it is considered a wear part that needs to be replaced. The problem with watching/monitoring is that failure isn't something you can reliably detect before serious damage occurs. So I replaced it for peace of mind. The engine on mine was checked and it's clean in terms of internals and there was no metal in the oil pan or filter. Odds are I just got a properly aligned engine that didn't wear out the IMSb as quickly as others. - RMS: once the tranny was dropped a couple seals & hoses looked to need replacement, so I replaced several seals & hoses that are relatively low cost parts that were several years old and showing wear. This ended up including the AOS, RMS, various washers, a bolt on the tranny/engine mount, etc. My goal was to spend money now to refresh it, then monitor. - Others: Don't install a lightweight flywheel without a full rebuild from a good builder. They tend to break crankshafts in otherwise OEM motors like the 3.6L. Enjoy, that's a pretty cab. Looks to be in great shape. Cool wheels too!

Congratulations and welcome! You got a beautiful 996 cab. My indie swears by Liqui Moly oil. I think the recommended weight is 0W-40. If your engine has the single row bearing then I'd say upgrade. IMS Solution is arguably the best replacement. If it has the dual row you can probably leave it alone. Most choose to replace the clutch (and possibly flywheel) and the RMS when the IMSB is being done. Oh yea - don't forget engine mounts. Otherwise, enjoy the driving!

AOS seems to be one of the biggest engine killers. It's recommended to replace it every 3 years, 2 years if tracking.

Great-looking car, congrats! Your list looks good. As for the following: Not sure about : Water Pump, if so which brand? If your are doing other stuff, sure. Coolant Change: Yes Power Steering Fluid Flush: Don't think so, but I'll let others chime in. Help: IMS, should be done or just watched. Also what else would you do if you are doing this? You will get opinions all over the place on this one. No set answer. If you do the IMSB, yes. RMS? If you do the IMSB, yes. Clutch? If you do the IMSB, yes. AOS? Yes.

If there is no record of the motor mounts ever being replaced or the tail pipes sag a little I would recommend changing them. Cheap and makes a big difference.

Nice car. Shocker(not) - it's silver. Heat kills. It kills a lot of things. Best and least costly upgrade I've done so far is the center rad kit and 160F thermo with new coolant. Improved AC function, less fan use, less strain on alt, better hot oil pressure(less hot of course), and so far, either better fuel econ, or I'm not driving it as hard as before. When you do this job, you also want to remove the rads from the car, and clean the heck out of them from back to front with air pressure, and water spray. The oil filter should have been cut and inspected prior to purchase, so that's the one I would do asap. Maybe get that LN full flow oil filter kit? BTW, there is a chip detector that used to be avail for the oil sump, but I don't know if it's still offered.

The list has been updated with everyone's suggestions. One thing not yet addressed in the suspension, what pieces should be updated? On the Cayenne's all the rubber mounting points where gone after 10 years, will this car be the same? Then there are the struts, this will be just a fun street car so not looking for highly upgraded parts. Will Do: Oil Change, cut filter apart to check for particles (also done with PPI) – Mobil 1 0w-40 or Castrol 5w-50 Oil Filter - Mahle Plugs – Beru, Bosch, or? Air Filter – Mahle Cabin Air Filter - Mann Bleed brakes (pads / rotors are good) - ATE TYP200 Belt (do the tensioner and idler pulleys need done also) - Continental Fuel Filter - Mahle Transmission fluid - Mobil 1 Delvac 75w-90 Diff Fluid - Mobil 1 Delvac 75w-90 Coolant Change - OEM Water Pump - RMS – OEM Clutch – Still not sure on brand AOS - OEM IMS – LN Engineering (Have to take car apart to figure out single or dual row) Help: Plugs – (Brand: Beru? Bosch? or?) Clutch - (Brand: Sachs? OEM? LUK?) Water Pump – (Brand: Laso? Pierburg? Other?) Suspension – Don’t know what should be done Thanks for all the input so far!

Plugs – Beru or Bosch? pick one, it does NOT matter. Water Pump – Pierburg is an OEM supplier w/o PORSCHE part #/price tag Clutch - SACHS is an OEM supplier Suspension - take a gander over here: http://www.pelicanparts.com/catalog/...n-Steering.htm

You might look at Driven DT-40 motor oil. It was developed specifically for this engine and has a better wear package than Mobil1.
