Excessive Fuel Consumption and Poor Overall Performance

Excessive Fuel Consumption and Poor Overall Performance

Recently we had a 996 Coupe in the shop, the customer’s concern was that the fuel consumption appeared excessive and the engine seemed to be less responsive than normal. We ran a complete controller interrogation, meaning we scanned all the control modules (computers) in the car for faults with the PIWIS (Porsche Integrated Workshop Information System) scan tool. Primarily we were searching for faults or fault codes in the DME (Digital Motor Electronics) controller AKA the ECU (Electronic Control Unit), there were no faults present. At this point most technicians would conclude that since there are no faults present, there must not be a problem, however, this is not always the case. Through experience we know and believe that the customer is usually very familiar with the operating characteristics of their car. With this in mind we continued our diagnosis. We performed a test on the pre-catalyst (before the catalytic converters) oxygen sensors utilizing a DSO ( ... read more

Callas Rennsport Change!

For the first time in 20 years, in an effort to handle our clients more expediently and just improve our overall quality, we added/moved one of our most valued technicians, Casey Gervig, into a “Service Adviser” position. We have purchased all new computers (network) and actually are converting from a DOS to Windows based operating system (most of you will laugh). We are also updating our automotive service system to the new Scott Systems Maxx Traxx software. Needless to say, we are now looking to hire a new automotive technician to fill this void. Callas Rennsport is immediately growing and accepting resume’s for this new position. With Tom Prine and Kelly Callas in our main office, Tony Callas and Casey Gervig in our shop office, 4 master technicians, 1 apprentice technician and 1 helper out in the shop. 10 individuals that still offer personal, detail-oriented service in this fast-paced world. Thank you for your support, and we lo ... read more

Living with the M96 Engine and the IMS

Today we know that the IMS (Intermediate Shaft Bearing) has been a major cause of concern for owners of 986/987 Boxster and 996/997 Carreras. It is generally accepted that far fewer problems are being experienced with the M97 engine, but that said, there have been IMS bearing failures in M97 engines also. Unfortunately, the IMS bearing in the later M97 engines cannot be easily replaced like in the M96; the later M97 requires complete disassembly of the engine for IMS replacement. One of the main concerns relative to these later M97 engines is how the factory’s larger IMS bearing will hold up over the long term when the miles driven get well beyond that of the 100,000 mile mark. The potential for serious engine issues is not something new for those of us that have owned 911’s over the years. For those who have, it is likely you are aware that there have been multiple problem areas with these engines. Oil leaks for all years. The cylinder head studs in the 1975-1989 911’s.

Porsche Clutch Systems 101

Manual gearboxes have always been synonymous with Porsche. Although the Sportomatic, Tiptronic and currently the PDK automatic transmissions are great and have a loyal following, there is just something really cool about working the clutch and shifting through the gears in a Porsche. Every car with a manual gearbox includes a clutch at no additional cost, well at least initially. We are often asked how one knows when a clutch is worn out or going bad. Generally, this can be dependant on a number of factors and in some cases when the vehicle was manufactured. For example, all Porsche’s that have a clutch cable, if there is no more adjustment length on the cable available, and the clutch is slipping; it is time for a clutch replacement. Porsche has not utilized a clutch cable since model year (MY) 1986, so that method of diagnosis is only applicable to that year and earlier models. Starting in MY 1987, Porsche utilized a hydraulically actuated clutch ... read more
