Hello Porsche mates, I came upon an intermix issue - coolant with oil, at least the coolant looks like chocolate shake (or coffee with a lot of cream). The usual symptoms before this discovery, 1) Temperature indicator lit up even though the operating temperature was around 180F. 2) Coolant was very low, so filled up with coolant/water but noticed this not so salubrious coolant - very liquid still not sludge like a few other have seen. 3) May have overfilled cos an overnight leak was found near the right rear wheel.... I had the car towed to my mechanic, the next day, but while he hasn't completed the diagnosis, he does suspect a cracked cylinder head. I am wondering about the oil cooler fault as seen in a few forum hits but not confirmed yet. Oil is clean - not coolant there... I may be looking at a $6K hit for this and on the wall towards fixing this, if confirmed as a cracked cylinder head. Reasons 1) 2000 Boxster S has almost 185K on the odo - though new clutch, water pump, 2 AOS, fuel pump, 2 MAF and convertible transmission motors, and a bunch of other regular fixes....it may be worth just as much, $6K , so not sure if it worth spending as much, only to find another $K++ issue lingering around. 2) Suspension groans once in a while... 3) Cat throws a P0430 once in a while.... 4) I've driven the car for 12yrs now so wonder if it is time for a change.... Appreciate your thoughts on 1) Is $6K a fair price for repairing a cracked head or should I shop around, if identified as the root cause? 2) Given the car's year and miles, is it worth fixing this issue? 3) What should be a reasonable price for this car as a roller, has the M030 package, and litronics but stock otherwise, if I decided to move onto something else? I realize #2 is pretty subjective - I've enjoyed this car for many fun years and hate to let it go but plunking $KK into an 18yr old car, doesn't seem wise, even if I would like to keep the car. Thank you for your time here. Cheers, Vish
Back in May I found the dreaded oil-in-coolant, followed by coolant-in oil. I got the engine out of the car and the heads off, and away they went to Len Hoffman in Georgia. He confirmed yesterday that I've got a crack in the 1-3 head. He's doing the repair along with some other maintenance items and port/polish. The lifters and fuel injectors are also away for service. I'm aiming to have my 996 back on the road in the spring, running better than brand new with a bit more umph from the head work. Anyone else had work like this done? Just wondering what to be looking forward to.
Just bought a '99 Carrera w/ 28K miles. My intro to Porsche ownership hasn't been smooth, but I love the car so I'm determined to whip it into shape. Bottom line, there's milkshake in the coolant reservoir, and I have to top up the oil every day. My mechanic (whom I trust) flushed the thing out a zillion times, but the problem hasn't gone away. He says the engine is shot and needs to be rebuilt by a Porsche specialist. Asking around turns up the notion that it's either a cracked head, cracked cylinder, or slipped cylinder. So I need a good rebuilder in the NYC area. Actually I'll go anywhere between Boston and DC, but would prefer to stick close to home. My impression is there are a lot of sharks out there, so I'd love to get people's input about shops they have experience w/ and trust. Thanks!
Hi my wife bought last July a 2002 996 Carrera 4 with 96 000km. The full maintenance history being supplied with the (German import) car, and being a hobby mechanic, I did the maintenance incl changing spark pugs, oil (Mobil1), filters, etc... all according to the maintenace schedule provided on this site. By the way great site ! Now 7500km later, my wife tells me she got an oil level warning message. First time since 7 months I open the lid and pull out the oil dipstick. The oil level is just at the minimum mark. So I decide to top-up with some Mobil 1 and remove the oil filler cap. I was horrified to see some accumulation of crème beige thick deposit. :eek: Nothing massive, but on the inside of the cap and on the inside of the filler tube irregularly and at some places 1mm thick max. I checked again the colour of the oil with the dipstick and it is transclucent with the colour of (english beakfast )tea with no traces of intermix. I checked the cooling water reservoir which is just above minimum level (but I do not recall at which level it stood 7 months ago) and the colour of the fluid is translucent and yellowish. No traces of mayonnaise anywhere here. I topped up the cooling level and oil level... the engine starts well, does not smoke, runs smootly on all 6 cyl... Could this formation of deposit in the oil filler cap be caused by the very low temperatures we experienced the last months in Belgium combined with the fact that my wife only travels 40km every day (20 in the morning and 20 in the evening) and therefore the engine nevers get hot enough to get rid of some 'natural" condensation in the crancase?? In this case this could be "normal" for a 996... At the other hand, once the engine reaches operation temperature (which is at this season after +-10km) she got a firm foot and does not shy taking it in higher revs... What shall I check next....coolant level and oil level (+ deposit evolution) I will certainly but shall I check the oil-cooler for faults?
