924, 944 and 968 Servicing tailored to your requirements

With its roots stretching back to the original 924 in the mid 1970's which evolved into the 924 Turbo, Carrera GT and 924 S, the 944 was released in 1982, featuring the new 2.5 Litre engine with a complicated belt arrangement requiring specialist attention. Later a Turbo model was introduced, 16 valve variants and capacities of 2.7 and 3.0 Litre also evolved. Eventually in 1992 the model was replaced with the 968, featuring variocam variable cam timing and a new body design. Each model of 924, 944 and 968 requires its own attention to detail only available from an experienced specialist. If looked after correctly, there is no reason why this model should not last forever and provide the same driving experience as they did when new.

At JMG Porsche we are familiar and equipped to deal with with both the earliest 924, 944 through to the last 968. This includes the 924, 924 Turbo, 924S, 944, 944S, 944S2, 944 Turbo, 968 and 968 Club Sport. We are even experienced with the more unusual 924 Carrera GT, 944 Turbo Cup, 968 Turbo S and 968 Turbo RS.

Selecting the correct service for your Porsche can often be a confusing task for those who do not deal with it every day, more so if you only cover few miles per year, so we tend to recommend that when you need servicing ask us for our advice, we will be more than happy to ask you a few questions and reply with the ideal service for your Porsche.  If on the other hand you are sure which service you would like performing from the factory schedule, we are also more than happy to do so.

As part of the service your car will be inspected beyond the usual items listed by Porsche to be inspected. Should we find any problems, we will try to call you so it is important to make sure you are available by telephone and if you are unable to answer our call, to call us back as soon as possible so we can discuss the issues and if need be, so you can authorise any additional repairs.

We are probably more experienced at maintaining, repairing and modifying these models than anyone else in the UK and possibly the world. Our chief technician and managing director, Jon Mitchell is also the author of books on the subject and the technical advisor to the Porsche 944 registry of the official Porsche Club of Great Britain. Beyond this we have experience of building some of the most powerful 924, 944 and 968 turbo and non turbo Porsche in the UK and possibly the world. In short, we probably know more about these models than Porsche do!

Interesting service and repair information for the Porsche 924, 944 and 968 models.

Service interval - Even though the service book specifies six monthly and yearly services. We would strongly recommend that all Porsche models are serviced at least yearly or every 10,000 miles if more than 10,000 miles are covered per year to avoid expensive repairs and to potentially catch issues early, where they may be less expensive to repair.

Engine failures - Not as common as you would expect, we at JMG Porsche have never had to replace one of these engines due to wear, however we have had to replace many due to insufficient servicing and maintenance, but there are still worthwhile ways of avoiding unexpected large engine rebuild costs. One of which is proper servicing by a real Porsche specialist, which may not need cost as much as you think. There are also some ways to avoid unexpected bills by following some of our other advice bellow.

Brake fluid - Did you realise this should be changed every two years? Not doing this can cause problems with expensive parts within your car, such as the ABS pump or any part of the brake hydraulics due to water contamination as the brake fluid actually sucks moisture out of the air (hydroscopic), so even if the car is not used, the brake fluid must be changed every two years!

Water Pump - Often thought of as a part which fails with age, mileage and quite suddenly, leaving you stranded, our expert technicians are used to inspecting these during services, and so may spot tell tale signs of failure long before they become an issue, so saving you from the indignity of being broken down at the side of the road. A 944 and 968 Waterpump is also part of the cambelt drive mechanism, so it failing can cause serious damage to the cylinder head and engine as a whole.

RMS - Rear main seal - Something else you might see horror stories on the internet about, these used to be a real problem and Porsche re designed the part several times to arrive at the current design which is the only one we at JMG Porsche use. Like an IMS Bearing replacement, this is best performed during a clutch change, however on tiptronic models or on cars not needing a clutch, they can be changed at any time.

Transmission services - Not clearly noted by Porsche for when the transmission should be serviced and this vital expensive part of your car should not be overlooked. Just like your engine, the transmission is filled with oil/transmission fluid, which over time degrades. Not only this, but not many realise that many Porsche transmissions also contain a filter, which becomes clogged over time and can starve your transmission of lubrication, causing expensive repairs. We recommend all Porsche transmissions are serviced every 4 years or 40,000 miles, whichever comes soonest.

Diagnosis - Long has gone where cars had limited electrical equipment and a wiring diagram could be found in a manual from Halfords. Now the Porsche models have multiple separate computer systems, which all talk via networks, and many sensors to feed those computers with information about the world around it all tied together with many hidden wiring looms of thousands of wires and connectors. This can mean that in the event of your Porsche suffering an electrical issue, it is important that a Porsche specialist auto electrician is available, as we have at JMG Porsche. It is also important to understand that sometimes, finding the fault will not be as simple as plugging in a computer.

Drive Belt - Many of you may have had cars where a drive belt, timing belt or cam belt needs to be changed at a regular interval. Your Porsche model has a belt which should be changed every 4 years. Failure to do so can cause instant overheating, loss of power steering and damage to the engine very suddenly. We recommend you have this changed at least every 4 years.

Cam and Balance belt - The 924S, 944 (ALL) and 968 (ALL) have a cam belt and balance belt, which has to be set to a very precise tension and run across various pulleys, tensioners and rollers to function correctly, if these are not maintained with a new cam belt and balance belt every 4 years, and a new waterpump, tensioners and rollers (as well as front engine oil seals) every 8 years, the consequences can be catastrophic to say the least.

Brakes - The Porsche 944S2, 944 Turbo and all 968 models are fitted with Brembo callipers, which overtime suffer from corrosion build up which can cause the pads to stick and bind up within the callipers or even make it difficult to fit new pads. When this happens the calipers require a service rebuild of the slider plate mechanism, which needs to be performed by a specialist with the right experience, techniques and tools to make the repair more than a very temporary one.

Heavy clutch? - A heavy feeling clutch which is stiff to use is not normal on a Porsche and often a sign that the clutch has almost worn out. Ignoring this can cause further damage, such as to the dual mass flywheel and clutch fork.

Alarm system - At JMG Porsche we are experts of all Porsche security systems and have reverse engineered all the various control units. This not only means we can program new alarm control units and keys to your car, just as the main dealer can, but in some cases we can repair your old alarm control unit and keys, or in some cases recover your old keys to be used on the new alarm control unit, which is a service unique to JMG.

Alarm system causes - In most cases the cause of alarm control unit failure is water damage, we can perform modifications to your Porsche model to help mitigate the chances of this happening to your Porsche.
