judibake posted a topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Two years ago I traded my 2001 C2 (125000 km) for a 2003 C4 with tiptronic (120000 km). Neither have had the IMS bearing replaced. I've read TOO much about the bearing experience. Last fall I changed the oil and filter and adjusted the level after using the car on several occasions. The oil level registered just at the full capacity electronically and manually. The car was then stored for 4 months when I checked the oil before restarting. It was 1 quart down, so I added a quart and it has remained just under full. There are no signs of oil leaks and the anti freeze is clean. Any explanation for the loss of the quart? This got me thinking about oil and lubrication and possible relation to failure of the IMS bearing. I assume that the proper oil level is necessary to provide adequate lubrication for the engine but does the proper oil level truly reflect the ability of the oil to lubricate the IMS bearing? I don't know the mechanism for its lubrication but could it possibly be enhanced by adding an extra 1/2 to 1 quart of oil? There are varying opinions about overfilling I quart. Is there any rationale to this suggestion?
judibake replied to judibake's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Thanks for all the options. The correct dimensions are 35x52x22 and Autozone has one for $13.95. Probably the easiest to get.
2003 C4 cab tip. I just determined the source of the noise coming from the AC area when the AC is switched on. I need a new AC clutch/pulley bearing. The part number is 35BD5222DUM18A which my part source in Toronto can't find. Would anyone know a replacement equivalent part number that I could possibly use to order the part? Thanks for the forum. It's very useful.
judibake replied to jhshelton's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)If the codes suggest a problem with the secondary air injection SYSTEM, I've been there before. Do not fail to assess and replace the vacuum reservoir at the beginning of the repairs and not at the end when all else fails.
judibake replied to jhall299's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)When I purchased my car the label was also missing. Fortunately I had the original owner's manual which has a copy of the label within. With your computer and printer and some time playing with fonts and sizes, you should be able to print your own copy that you can then glue to the hood. The copy from the manual did not copy well. porsche hood label.doc
2003 996 C4 Cab Tip. I had the AOS replaced 5000 km ago and the vent hose to the back left intake manifold was fine. On examining the engine the other day I noticed some oil covering the corrugated hose and think it may need replacement. I've read everything I could get my hands on about AOS replacement and mine was replaced by dropping the engine. Others have done so by removing most of the accessories of the rear left engine space and worked in this area and below the engine with the car elevated. It looks like the vent hose alone can be installed easily?? by unclipping it front and back and pulling the new one through. Am I being naïve or can it be done with not too much difficulty.
judibake replied to Jonas007's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Just an additional thought from a DIYer. My AC clutch packed it in last fall and I was presented with all the valuable information that is listed above. Of note was the price of a new clutch which always included the compressor which in most instances did not need to be replaced. Of course, the replacement of the compressor is a much more involved exercise than the relatively simple replacement of the clutch pulley and its bearing. I have been involved with auto restoration for decades, and more often than not, new or restored parts were not available. I would find a used part, either refurbish it myself or have it restored by a professional. This mode of thinking somehow does not exist anymore. Everything must be new on installation, presumably because there are no guarantees by dealerships or indys on installation of used goods. I think a sound used part is more than adequate if the repair is easily performed by a DIYer. IN THE PROPER INSTANCE. DCauto.com has provided excellent used parts for my 2001 C2 and 2003 C4 Cab tip in the past including an excellent AC clutch for $100 including shipping. (3 years working normally). No need to use the electromagnetic coil if just the pulley/bearing requires replacing. I hope members will not think this thread blasphemous but this solution has worked for me for decades. 1958 Austin Healey BN6 1960 Austin Healey BN7 1957 Jaguar XK140 OTS 1952 Jaguar XK120 Coupe 1957 Austin Healey BN6 2001 Porsche 996 C2 Coupe 2003 Porsche 996 C4 Cab tip
judibake replied to judibake's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Thanks for the advice. Sounds like a job for my indie who has the calibration equipment. I'll get back to the forum regarding the outcome.
This January I purchased a very well maintained 2003 C4 Cab with Tiptronic transmission. I have had no issues with it to date. With top down warm weather this past week I happened to look at how the top appeared in the down position and the relationships of the front panel containing the overturn pop ups, the middle panel which is the front of the top in the up position and the rear metal clam shell. There is a 1 1 1/4 inch gap between the front and middle panels as seen in the attached pictures. The top otherwise works perfectly well and opens and closes with ease. There doesn't seem to be any other obvious poor alignments. Obviously I have checked with other Carreras and this gap does not exist. Any advise on this would be appreciated.
judibake replied to judibake's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Thanks for the information. I take it that the Gillet mufflers are stainless steel and under the circumstances that you have outlined, they can pit and corrode. The seam that appears most vulnerable is the bottom one. Probably due to start up moisture being dependent and its mixture with contaminants from within. I guess external salt and water in winter conditions would also contribute. Just for the record, if you wish to buy used mufflers, look at the bottom seams VERY carefully. Also even if they appear intact, you still do not know what's happening within. Southern states and low mileage may be of equal importance..
judibake posted a topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I'm in the process of looking for mufflers for my 2003 C4 Cab Tip. Some mufflers have Gillet stamped on them and others do not. I've been told that the Gillet mufflers are stainless steel. Are they indeed? If so why do they usually have their bottom seams corrode out after 80000-100000 km?
judibake posted a topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)My 2003 Carrera 4 Cab with Triptonic Tx will require new mufflers within the year. The bottom seams are showing some minimal corrosion. I get the feeling that the mufflers for my car may be different than those for a coupe, manual Tx or RWD. I would appreciate the part number for the mufflers for my specific vehicle. Obviously I can't get to them with the mufflers in situ in the car. As well I've been looking at SS Agency Power AP-996-170 replacements. Any comments would be greatly appreciated. MG
I don't wish to open this topic for general information again. There is enough information on line about these codes to fill a large book. Over the past 3 years I have attempted to find the cause of these codes in my 2001 996 C2. The car was looked at and presumably repaired at 2 independents as well as a Porsche dealership. All tubing, the single check valve and the vacuum switch had been replaced with the guidance of numerous smoke tests. Another independent (Porsche, Audi and Benz) FINALLY identified a VERY small hairline crack at the base of the reservoir. The pros on line usually leave this possibility at the end of the list. For minimal additional expense the entire vacuum system from the black/white valve on the intake manifold to the check valve should be replaced on the first go by someone reputable. Unfortunately it may take some time and money to find that reputable shop. Safe driving.
Hi, I have a 2001 C2 that had a similar problem. I realize that there are many articles and threads written on oil leaks and I don't profess to be an authority but I found a simple solution in my case. I spent several hours cleaning the undersurface of the engine to try and identify the source of the leak. It appeared to be coming from the front ends of the cam covers. My car has 140000 km on it and city driving with potholes etc that are inevitable. I understand that the cam cover bolts are not torqued very aggressively and found that MOST were loose but not to the point of turning them with your fingers. I GENTLY tightened all of them no more than 1/4 turn and voila - no leaks for more than 2 years. Just an instance that resolved my problem but may not be for others. Hope this helps.
I have the opportunity to purchase a 1988 Carrera with a body in very good condition. The car was last licensed in 2003 and has been left outside in a covered shed since then. The owner of course suggests that the car ran well up until he abandoned it and lost the keys so I am unable to examine the boot, interior and particularly the engine compartment. Through the window the dash, seats and trim appear quite good. The car amazingly has no obvious rust but my examination is limited. He had a locksmith try to open the door unsuccessfully and has suggested that we break a window. My suggestion was to go to a Porsche dealer with the VIN and get a new key if possible. My major concern is outdoor abandonment for over 10 years in the Toronto environment. I have completely restored 4 cars in the past and am willing to refurbish this one if it can be done without a major restoration. I also have no idea what to offer him knowing the unknowns and probable costly surprises of the purchase. This may be a situation that many members would love to be in but I'm not wanting to undertake a large time commitment at this time. Help.
