I say this because I am getting close to K on mine. My plan is to get myself a new one no more than 3 years old when I hit some key life milestones pun intended in Can it make it there? Even the mechanics scratch their heads and say I am a first for mileage seen on a Boxster. I will say this -- maybe it dies tomorrow, maybe it goes another K. Regardless, it rides and sounds as smooth as a new one No knocking, no leaks, no noise I'll keep ya'll posted -- for now, I feel as though I need to keep running it, just to see and let the world know what they can really do..
Last edited by boxsterlover77; at AM. Marc has k miles on his and the engine has never been opened up. Take care of it, fluids more regularly than any factory recommendation. But most of all, enjoy.
If you want a speedy,reliable convertible it is hard to bet an S But it is compromised for any long distance driving. All I think my indy had to change was ignition coils, sparkplugs, the MAF once and the brake switch cheap plastic. Car feels just like new Go figure Porsche cars are certainly not 'perfect' engineering, nothing is in fact, but they are certainly a good product none the less.
I'll buy again. Even the best Boxster can be an awful financial proposition when you see the real world value. I'm stupid enough to buy a k mile Porsche from 98 2. Have overhauled the engine - piston broke, cylinder lining replaced with sleeve..
Also have a 97 base with just over k KM, still on original water pump maybe they made them tougher back then? Had a new clutch put in when I got it about 15k ago, did LN IMS upgrade at the same time for 'new owner peace of mind', though it probably didn't need it.
Still going strong Originally Posted by oldskool I have a 99 Boxster. I purchased it in Sep 09 with , miles. Today it has just under , miles. I believe it has the original IMS. I am fortunate that I live relatively close to Woody. Some of the parts I've gotten from him have saved my bacon on more than one occasion: two radiators, an axle, sport seats, a rear trunk release cable and a space-saver spare tire. BB code is On.
After driving the car let it sit and idle. The front radiator fans should come on and the engine should maintain a steady temp. If the engine continues to warm and will eventually overheat, walk away. Turn off and take a look at the coolant level — it should have risen and be falling back toward the cold level.
If the level has gone down or is still at the cold level, there could be a small coolant loss through a cracked liner. The trained nose can smell coolant from the exhaust when the engine is running. A coolant sample should be free from oil or debris. Let it sit and separate if necessary. A Porsche repair shop can definitely help here. Lift the car and have a listen from below while the engine is running.
You might need a repair shop to do that for you. Much of this is the proximity of your ear to the valve train and the exhaust headers. These engines are famed for cylinder scoring — deep gouges in the cylinder liner, usually associated with a knocking noise and eventually catastrophic engine failure. The root cause of this issue is open to discussion, however, wear in the piston rings and liners causes the piston to wobble.
The wobble occurs at the bottom of the stroke and results in the piston skirt dragging against the cylinder wall thereby scoring the liner.
The rhythmic knock is the piston changing position at the bottom of the stroke and hitting the liner. In many cases, even with the head off the engine, the scoring cannot be seen until the piston is removed — it can be way down at the bottom of the cylinder below the lowest point the rings meet the walls. Sometimes it can be seen by scoping down the spark plug tube, but the best view without disassembling the engine, comes from removing the oil pan and scoping from the inside.
Timing is everything; especially in comedy and engines! The opening and closing of valves, the piston rising and falling in the cylinder and a spark are required at precise times during an engine rotation.
The major moving parts are connected by chains and these ensure the relationship between those moving parts is maintained regardless of the rotational speed. The rotation is measured in degrees of a full circle. So, for example, at degree zero; piston 1 should be at the top of the cylinder and the intake and exhaust valves closed. This is known as top dead center or TDC.
Naturally over time, the components supporting those timing chains will wear — the chain itself, guide rails, tensioners etc. The engine management system is measuring the angles in every rotation and within a range of angles, can adjust the timing of fuel delivery and spark to compensate for wear changes.
However, extended wear can produce an angle outside of the allowed deviation range and a fault condition will be set. The earlier Boxster experienced issues with stretching timing chains and significant wear on the timing guide rails. This caused a nasty rattle at startup and generally set faults during acceleration. Most of these issues were corrected in later cars, but during the life of an engine you should expect that these vital timing components will wear. You need a clear picture of where the used vehicle you propose to buy is in this wear process.
A competent Porsche repair shop can tell you what the deviation angle between the cam and crank is during a used car inspection. This is a simple read from a diagnostic device and a clear indicator as to the health of the engine timing. The change in angle will affect performance and is almost certainly not something you could pick up on during a test drive of an unfamiliar car.
Replacing the chains, guides and tensioners to correct this problem is not an inexpensive proposition — it is however, relatively straightforward if your budget allows. Before buying any car, it is essential to be certain when the last time the engine management fault codes were cleared and to check the status of the emission monitors. Again, this is easy for a competent shop to check or indeed the DIYer using a handheld scanner. How hard has the car been driven? Taking the engine to the red line for RPM is a good thing, but going over the red line obviously can cause damage.
A gear change at red line will actually cause the revs to increase slightly momentarily — nothing bad here. But, if you select the wrong gear, the engine revs to go way over the red line. Thankfully, Porsche engine management records many things and one of the most significant is known as an over-rev situation. Data is permanently stored within the ECU showing running hours and when engine events occurred.
There are six levels of over-revs recorded ranging from the engine being red-lined through to what would be a potentially catastrophically high RPM event. Events in the first category suggests the car has been properly exercised, but events in the higher categories could be hiding a potential life shortening engine event. Many Porsche owners like to go to track days.
On the track, gear changes will occur right around the rpm maximum red line. These events will be recorded if they reach the lower levels of the over rev counter.
Multiple recorded events in the lower over-rev categories could be a sign of how much track time the car has experienced. We recommend you use the help of a Porsche Repair Shop to read this data and give you an assessment. There are some common areas where oil leaks occur on the Boxster engine. Most are easily fixed and are part of the normal wear and tear process.
One of the most common areas for an oil leak is the engine rear main seal. See our common problems page for more information. Leaking oil used to just be seen as a annoying stain on the driveway and a potential fire hazard. However, modern cars feature many electronic engine management systems that can potentially be severely damaged by oil ingress. Oil leaks should not be a barrier to purchase, but they should be considered in terms of the purchase price — what appears to be a minor oil leak could turn into an expensive job.
Again, this is where a competent shop should be able to accurately asses and relay the cost of an oil leak repair. This is a machine that is built to be driven hard, so that leaves many consumers wondering how long do Porsche s last and what is the Porsche engine mileage? According to consumer reports, Porches hold up extremely well in comparison to other brands.
They are built to perform, yes, but they are built to perform for many years. Porsche engine mileage can be rated at , miles and 10 years. Like any vehicle, Porsche s last longer with proper and routine maintenance and care. Most Porsche vehicles will last you up to the ,mile marker and beyond. As always with any vehicle the average life of the car depends massively on factors like driving habits and service history. Porsche is a brand known for its longevity and these vehicles stay in good conditions for years after purchase.
These are porosity issues, cylinder and sleeve related problems and intemediate shaft failures. I agree. Once you have made it to 50k the motor has proven itself and mfg defects are unlikely. Now the issue becomes heat and wear. Give her regular service and watch your temp gauge. Make sure you do proper maintenance, with quality parts. Use quality fuel of the proper octane rating. Let the car warm up properly, especially during cold weather.
Keep your foot out of the throttle until the engine is fully up to temp. Your car should run for a long, long time. You can post now and register later.
