Smoke, oil consumption, and fuel trim issues with various fault codes can be traced to an internal leak at the oil separator.

1998 Porsche Boxster Problems
If the vehicle cannot return to run position after start or if the interior fan is not getting power, it may be the electrical portion of the ignition switch has become erratic or has failed. The entire switch assembly should be replaced.
Engine oil leaks can occur at the rear main seal and/or intermediate support cover o-ring; a revised seal is available. A careful diagnosis with proper tools is necessary to verify dimensional accuracy of the crankshaft to engine block.
The power windows not lowering when the Cabriolet top latch and/or door handle is operated or lowering unexpectedly while driving can be caused by a failing Cabriolet top or door handle micro switch. Diagnoses will be required to determine which switch is at fault and will require replacement.
Persistent coolant loss can be caused by a small leak at the coolant reservoir. Our technicians tell us the leak may not be visible due to the trunk carpet hiding the leak.

1998 Porsche Boxster Reviews
I love my boxster and have made into a project, to get my 98' in perfect running order. First I bought it with 89k. Now 9 months later it has 99k. First I had a 90k inspection done. A small linkage on the front was replaced and a tube leak around the spark plugs. I had had several noises come from the starter, so I had it replaced. Next i made a mechanical insurance policy by having the IMS bearing replaced along with the rear main seal (known problems that can kill any porsche 1997-2008). While having the Trans out to do this repair I had the clutch replaced with only a parts bill since the clutch had to come out anywhey. They made note of cracking coils after this latest repair. 2300 miles later the car ran rough and I had it towed to the shop. And of course the coils went bad. Now the car runs better than ever and I am real happy. I now feel safe to drive this car anywhere. You could have a muscle car and never have any of these problems, but it would just be a car and not very good on windy roads, just good from a red light. On the road I get 25-30 mpg.
Once you drive it, you don't want to change it. Take this advice from someone who have changed around 30 cars so far. You will love Porsche for ever. I have a Boxster 10/1998 and I feel very happy about it. It never let me down so far.
