  1. Johnny-5, I am not in a position to say if you can or cannot feel an improvement using an aftermarket air cleaner on your Porsche. In my mind, to assume that you can, you also have to assume that the stock filters are in some way degrading and that Porsche knowingly provides air filters with their cars that are inferior. I do not have any basis or reason to substantiate these assumptions and they are not consistent with Porsche products. Hot Rodders in California found that cotton filters increase horsepower because it breathes easier than paper, and cotton could be washed. In Europe BMC
  2. I am running a 97' with 75,000 miles. Is this the general consensus that the entire Row M030 suspension, including springs, struts, sway bars and bushings, is the best way to go for better street handling?
  3. Simple green is on the stronger side. You can use Dawn dishwashing with enzymes which is milder as often as you like. Dawn, as long as you have enough, it surrounds the oil molecules and and lets them float away in water. You can clean everything. I used Dawn to flush out the engine last year when oil got into the water. I was not aware that any areas need to be taped off from soap and water on a Boxster. I put Dawn in a generic variable spray bottle. Straight or mixed with water it does not seem to make any difference. Just squirt it at the dirt and it floats away. You can flush a
  4. If you ever had a 914, please have your say. There is a 914 basher in Amazon.com Customer discussion Click: Amazon ~ Discussions: Once a year oil change: when is the best? This used car salesman who has probably never driven a middie, has been unjustly badmouthing the 914. Can everybody please chime in. He says 914s "were cheap and showed that Porsche engines are sludge monsters." It is unfair to young readers just coming in, to hear this rubbish without your opinion. Please go in there and straighten this guy out about Porsche!
  5. 1997 Boxster vin #WPOCA2987VS620323 The Bosch technical department told me to only use the original plugs not the new ones. What part number plugs can I use, and does anyone theorize why.
  6. The original cooler does not need any kind of adapter. it fits into the block, with four seals and four screws. These were the directions to replace the oil cooler. Although there was no reason to mess with the throttle intake. It does not show anything about draining the oil, or removing or replacing a vent line. There is no mention of any adapters, or air vent lines. Can you please tell me the order of the three hoses top to bottom under the oil filler hose? Oil cooler hose? Radiator vent hose? Coolant filler hose? Coolant overflow hose? Whoops that four, I
  7. Why couldn't you just run this to the engine vent line, with a "T."
  8. Jeff don't all the after market exhaust systems make more noise than stock. That is there trade off, they are tuned less to what your engin needs and make more noise!
  9. Two Porsche dealers, and the shown TSB 1001, seem to say that if you change the oil cooler to one of those new tiny ones, that you have to change all of this other stuff, and add adapters etc. It is a mess. The simplest thing is to just replace the original part and drive away. Porsche sees some connection between the oil pump in the front, the oil cooler on top , and the changes that would have to be made to the expansion tank in the boot. Changing the cooler will affect the velocities, the passage lengths, the volumes, and the breathing of the engine.
  10. >I really don’t see the relevance to this tread as the oil pump is on the other end of the engine from the oil cooler…

    I do not see the connection either. But two dealers, and the shown TSB say if you change the cooler to one of those new tiny ones that you should change all of this other stuff, add adapters etc. It is a mess. The simplest thing is to just r...

  11. It looks to me,that if the original part is not replaced, that is if a part with a different part number is put on. Then a new oil pump with double-sided mount must be installed, and the oil pump must also have an intermediate plate installed.
  12. Thank you very much. The dealer told me it was TSB 7-99, but it really was TSB. #1001 with a date of 7/99, for a 1997 Boxster.
  13. Does anyone know here I can find Technical Service Bulletin TSB 7-99?
  14. Believe me all I want to do this morning is go terrorize some two lane blacktop and pass a bunch of cars for the honor of the marque. But how can the same part fit both blocks, when as you can see the blocks are clearly different. One has flat oil passages, the others are recessed. They tell me the same part shows for both years, but they cannot confirm that the adapter fits all 1997 blocks. I am not trying to buy a part number, I am trying to find a solution to an oil leak. This is the newer block. The surface is flat, with the seals on top. This must be where the adapter lies. D
