Our article on how to interpret and make sense of those fault codes may help. Maintenance rarely solves a problem. However, neglecting maintenance can cause issues — check your last service update with our recommended maintenance schedules. Porsche vehicles have a number of regular sources for leaking oil. Some of the most common include rear main seal see belowvalve covers, spark plug seals and turbo oil supply line seals.
Less common are leaks from the cam seals and scavenger oil pump seals. Valve cover leaks are obvious and fairly straightforward to fix on most models. The valve covers do not have a gasket — instead a liquid gasket sealer is used.
The time consuming part is removing the old gasket sealer from the valve cover to ensure a good seal for the replacement.
Spark plug tube seals are also prone to leaking — leaks from the spark plug tube seals can be frustrating. The tube fills with oil and causes misfires by destroying the plug and the coil. If you see oil on a plug or coil, always replace the seals. The early engines had a plastic tube insert and the later engine features two seals.
The upper seal can be replaced when removing the valve cover. The lower seal leaking is more of an issue and requires removal of the camshafts. One of the most common, misunderstood and potentially destructive issues is an oil leak from the rear main seal on the Porsche engine. A leaking rear main seal appears through the bell housing joint between the center of the engine and transmission joint. The leaking seal will quickly destroy a clutch in a manual car if not addressed promptly.
The seal needs the heat of driving to remain sealed efficiently, so in some circumstances the leak can slowdown or stop during the driving season. Replacing the seal requires the removal of the transmission and in a manual car, replacement of the clutch at the same time is a good choice. The seal does dry over time and can leak, however, there are other potential issues that could also cause the seal to leak see Air Oil Separator below.
Causes of the seal failure should be checked thoroughly by a competent shop before you proceed to replace the seal. As an integral part of the emissions system, the Air Oil Separator AOS is designed to extract oil from gases in the crankcase. The oil is recycled to the sump and the gas is sent through the combustion path to be burnt and cleaned by the catalytic converters.
The AOS has caused numerous issues on Porsche engines. As the membrane in the AOS fails, oil is sucked into the air intake.
Initially this can show up as a check engine light for fuel adaptations and the oil can be deposited on the o2 sensors causing emission faults.
Of course, once it fails completely, the resultant huge clouds of white smoke are fairly obvious.4hk1 pressurising cooling system
At that point, it is clear what needs to be done. However, replacing the aos sooner rather than later can be a good precaution against other failures.
A failing air oil separator aos is the likely cause of rear main seal failure and oil leaks, as it is in other VAG cars. Crankcase vacuum exceeds the normal range in the engine under heavy acceleration and sucks in air damaging the rear main seal.Table of Contents.

Insofar as I am both an automotive journalist and a long-time Porsche Club of America member, I hear stories like this all the time. The difference in this case? It was a 2. These cars were about 15 years old back when I was in high school, and could be had in good condition for three or four grand. In a straight line, they were easy meat for a 2. The smart money bought an old BMWwhich could also be had dirt cheap and which would blow the proverbial doors off the VoPo. Things have now gotten officially out of hand.
My dinner companion paid somewhere north of 30 grand for his 2. For that kind of cash, you could get a five-liter Mustang, capable of towing a down the quarter-mile in less time than it could complete the task under its own power.
The lesson I would encourage you to ignore goes something like this: Given enough time, all Porsches will eventually become super-valuable, no matter how unwanted they are today. I strongly suggest that you do not follow that advice, with two potential exceptions we'll get into later. Porsche made quite a few of them; they were far more popular than the air-cooled generation cars that preceded them.
So the supply is high. The interiors did not wear well and the paint was subject to fading, so many of the es out there look pretty crummy nowadays. This is particularly true of the models. IMS problems aside, the is absolutely stuffed with fragile, fast-wearing and expensive components, many of which can't be reached without dropping the engine.
But the does seem to have a larger-than-average percentage of lowest-bidder parts. The Fried Egg Investment people will readily stipulate all of the above difficulties.Convertible Top WON'T OPEN/CLOSE GO UP/DOWN - FIXED! Porsche Boxster 986 Troubleshooting Tips
But they believe they'll be rendered irrelevant by skyrocketing resale, as happened with the 2. I recently read an article that said something like this: Eventually, the supply of es will contract as the bad ones are put in junkyards and the good ones are restored.
Buying a in is just like buying a SC in To begin with, the air-cooled cars have character that no modern car has.The convertible top on the Porsche Carrera is hydraulically actuated. This means that rather than using the traditional approach of cable and pullies, the car uses a set of pressurized cylinders to both open and close the top. Over time, the system can leak or fail, causing your convertible top to get stuck in either the up or down position. In this article I will explain the basics of the system.
The basic operation of the system boils down to the use of two hydraulic actuators, mounted inside each rear interior panel. Each actuator is fed by the main system pump. If the system is low on fluid, it can operate loudly and cause the top to stop working.
If you are having problems with your top, there is a chance you could just be low on hydraulic fluid. Sometimes simply adding fluid to the system can get it working again. Additionally, the fluid in the reservoir can go bad, especially if there are leaks or contaminants, causing the system to work harder. Begin by moving the convertible top to the service position. This is where the front edge of the convertible top is about inches from the top edge of the windshield.
This is so you can keep the body flap open and also gain access to the pump. Once the top is in the service position, look under the rear window flap to find the guide cable connections. These are attached to the car with two ball joints picture 1. The idea here is to keep the rear window flap down when the top is opening or closing. Pop both cables off the ball joints and fold the rear window flap up over the top.
Directly below, you'll see a carpeted area held in place with four plastic rivets. Pry the rivets out with a small screwdriver and carefully work the carpeting over the two large plastic blocks on either end. Once the carpet is clear of the blocks, pull the carpeting up and out of the car. You'll see the hydraulic pump for the system underneath. You'll also have access to the rear body flap motor as well as the DME computer and the relays.
Locate the two hydraulic lines going out from the pump to the actuators.Worried about potential repair costs? An extended warranty can provide peace of mind.

A new one was ordered and replaced. Clutch showing early sign of wear while releasing pedal. Known to Porsche as an "IMS" failure.The hydraulic wing lift system can never be fixed permanently.
Who wants to dismantle the wing mechanism every year or two to replace o-rings, then fill and bleed the mechanism??? We have cataloged 14 distinct causes for failure. Fix one problem, the next will occur. The factory wing mechanisms are getting older and are failing more often. For the first time, the Turbo lineup employed a 2-piece spoiler wing assembly built into the rear deck lid. This is the same concept utilized in the Carrera GT supercar. The upper wing is an inverted airfoil, or upside-down airplane wing.
The same principle that lifts an airplane up is used to push the back end of the Turbo down. Down-force climbs as the car reaches top speed, down-force pressure on the rear axle builds up to 20 Lbf [90 N].
No longer was the tail of the turbo floating! For the 6th generation Turbo, the 2-piece spoiler wing extends 1. The early water-cooled Turbos took rear down force to a whole new level! Shown before conversion to the all-electric eRam system. All too often Turbo owners experience a broken or malfunctioning wing or leaks under the engine lid from the cylinders, fittings or motor driven plungers. The electric motor spins a jack screw in one direction or the other, which pushes or pulls plungers via a threaded plastic block.
The closed system plungers force fluid through hoses into two spring loaded hydraulic cylinders connected to the wing. The microswitches send a signal back to the instrument cluster ECU computer controller to turn off the 12V drive motor.
The ECU tracks the time it takes for the wing to deploy. Upon failure, the only protection to keep the motor from burning up is a thermister overheat fuse near the motor commutator. Strangely, a discrete electrical failure protection fuse is missing, as a single fuse in the panel is for the entire back lid electrical; hydraulic system, light, e-latch, fan, etc.
Many root cause failures have been identified by Rennkit and our many customers. All are prevalent, given the age of these vehicles. The entire mechanism sits directly over the hot engine. Of course, part of the system is exposed to the elements with the wing up. We are finding a lot of dirt and moisture inside the chrome cylinder cavities.
Often one side of the wing lowers while the other remains up! When the wing is up, the hydraulic system is under high pressure. The tubing and banjo fittings are notorious for leaking — loosening up with heat cycling over time this happened to me :. They are very delicate, and can become brittle, crack and lose their pliability due to moisture, pollution, dirt, age, wear, sunlight, heat and other environmental factors. The seal is no longer maintained, allowing moisture and dirt into the inner cylinder area.Wispow free piano 2 keymap
The chromed tubes may bind up. This allows dirt and moisture to enter the inner cavity with every stroke. The inner cavity is where the narrow brass hydraulic cylinder and spring reside. But in reality — this may not be accomplished as only one side may fail. The actual piston and cylinder that raise and lower the wing are quite a bit SMALLER than the surrounding chromed outer cylinder, about the diameter of a pencil — cleverly hidden within the big fat outer cylinder.
Fatigue, moisture and dirt will eventually cause spring failure. This exacerbates failure and leakage at every joint and seal — since the entire hydraulic system both rams, fittings, hoses and both motor plungers experiences excessive hydraulic back pressure. The steel springs often break due to corrosion:.Table of Contents. Page 3 Please take the time to read this manual before you drive your new Porsche.
