My dad wanted to do something nice for me while I was out of town so he took my car to a new mechanic who said they worked on Porsche's all the time but it appears not as I just found out. They changed the oil, seals, plugs, etc...and I have been driving my baby 1998 Targa 911 the last couple days and just checked the oil since it has been smelling horrible! I just saw it has an excess of 4-5 quarts of Mobil 1, 15-50 oil above what it should be! Yikes!!! What is the worst thing that could have happened? Blown seals, hydrolics, failed bearings? What else? Please, any advice on how to proceed?

Did you pressure bleed them from caliper up to the reservoir? You need to do that because of the ABS valves.

I am not a Cayenne guy but first and formost the timing belt on Porsche's absolutely must be changed every 60k miles or sooner and the water pump every other time, just for good measure. A rough idle after 1 hour driving does not sound like a timing belt issue to me. I would call/attend a local Porsche Club of America (PCA) event and ask around as to who the best mechanic/shop owner is. In the mean time, IF it is the timing belt DON'T DRIVE IT!!!!! if the belt breaks while the engine is running, you may as well buy a new engine! Get very familiar with everything Porsche and your vehicle will last and love you for a very long time. If you don't it will destroy you and your pocket book!

I hope this gets you in the right direction!

normally that's the problem,

It does'nt. What was the problem with the car, that you took it to the mechanic for?

It sounds like whatever your dad did needs to be un-done. If you are getting hot air then you don't need to replace the blower or any part of it, it sounds like something is just wired up wrong. I would ask you dad what he did and if he can change it back.

if your chain becomes loose it will become very noisy and should be replaced since most nissans are interference engines which means lots of money for a new engine

sounds like your porche dealer is one of the "one for one" mechanics (repair it,no, replace it).assuming it is the diff,the pinion can be adjusted to reduce the noise on overun but you will need to get one of the old school mechanics to do this,as personally,ive only done one,in 35 years,i have even heard of some people that fit a thicker oil to reduce the whine........then sell the car.not nice.if you trust the guys that said its repairable,then they "sound"genuine enough.otherwise they would have tried to get you to change it (they make more money/take less time).

using chevron gas in the tank may be the easiest solution to your problem, don't ask me why but, it worked for me AND I WAS TOLD JUST AS YOU ARE BY ME.

im not a porsche expert bro but worked for gm for over 7 yrs and we had a cpl of porsches come through, there should be nothing special except fr the fact you should always change the oil with a full synthetic no high mileage **** or cheap oils.. Best ones on market for theses european cars would be mobile or royal purple the purple works very well for hard driving i use all there products for my drag cars and my dad uses it for his new BMW M5 but you should prob consult your dealer first porsche is a very delicate piece of machinery..have a good day..

you will yes my dad had this problem with his merc and you will just need it recoding or erhaps a new set of keys and recipors in the car.
