We tested several types of lubricants when I was in school and found that the type could cause wild swings in torque applied vs. elongation. Generic torque tables being used with lubricants is a recipe for disaster and can easily overstress a fastener. An article I read years later in AOPA (September 2000) seemed to have a very good discussion on the subject and is worth a quick read . http://www.aopa.org/members/files/pilot/2000/anp0009.html

I had a similar leak on my 996 that was solved by updating the hose clamp. There is a TSB that covers this subject for the 996.

I agree with logray. I have seen 100LL lead foul a plug firsthand Sometimes I would get lucky by doing a runup and leaning the mixture and sometimes my flight ended on the ramp due to lead fouling. The "low lead" is misleading.

Gates has a nifty polyrib checker. A belt may pass visual but the groove depths may be out of spec.

Your first number is not an engine number, it is the transmission type number G9600 is for years 99-01 G9601 is for years 02-05

Normal, especially after sitting for a few days

As Paul said, held in by the adjusters. Buy new ones since the old ones tend to corrode. The 2 flat nuts with the shoulders are placed on each side of the tray and the knurled nut is actually the adjuster. It may be easier to remove the wheel liner to do the major adjusting to avoid numerous removals of the light to get it right.

Are you talking about the one on the right? Offset box end wrench Left=Idler center=tensioner right=idler

It will not work. The flex plate for the turbo is 9 bolt and yours is 8 bolt. The bell housing bolt pattern is different on the transmission housing. etc. etc.

I have Cargraphic (muffler p/n CARP996ETS) They do not drone on the highway, but sound very aggressive otherwise (a little loud IMHO).

You need to remove the upper bump stop. New regulators come with two and are designed to work on both the Boxster and the 996.

Expanding on what RFM said, AT66565018 AT = Austauschmotor or exchange motor 1st digit = number of cylinders 2nd digit = normally aspirated 3rd digit = 2005 4th thru 8th digits = serial number

Look at the pattern inside the housing. The 996 clear headlight has a diamond/grid pattern where the 986 clear headlight has a linear/fluted pattern for part number 986.631.132.14. Otherwise, they are interchangeable.

I agree with JFP. I happen to know for a fact the only thing that needs to be moved from the old engine (tiptronic) to the new is the water neck (see pic showing neck transferred to old engine for core return) on a factory reman. Seems like you are just getting a long block?? Didn't see this option available in the reman catalog

You cannot overrev a tip. Surely Porsche knows this. Even if you rapidly downshift multiple times, the tip logic will only downshift when safe to do so.

I just replaced mine this weekend. Popped the lid to check the oil and noticed the crust. You should be able to look at the catch area of the tank or see the obvious crust on the cap. Mine was an -01 cap and it leaked so I would take Loren's advice and replace with an -04 version.

As others have stated, you will notice a drop in your gas mileage. When I had my 996, I experienced 2 mpg drop with no other changes. One side effect I noticed was water accumulation in the winter. I had to start adding a bottle of heet every couple of tanks.

I feel your pain. I suffered a broken valve spring a few years back. A simple bore scope inspection revealed a shiny smile on the top of one piston. A compression test confirmed zero on that cylinder with the others being fine. I exchanged PM's with another person here who went the repair route vs. replace. You could do a search and probably find the postings concerning this same issue. If he is still on the board, he may be able to give you some ideas on cost. If I were you, I would replace all of the springs on both heads at a minimum. BTW, my valve spring failure was not the result of an overrev....car was a Tip

JFP is correct. Dealers have been using Techron for years and at one point in time actually issued a TSB naming Techron specifically. I had great luck with the stuff in my 911SC based on the local dealer's recommendation to use it right before an oil change. I drove the SC daily for several years found the Techron was a must to keep the k-jet working properly. Never had any issues with the injection (except a failed warm up regulator) and passed emissions with no problem. I also used Techron for years in my 996. Ref. TSB 8510 issued Dec. 6, 1985

I wouldn't worry too much. I have 7 Type II's recorded at 0.1 hours. This likely occurred at the factory since it happened somewhere between 0 and 6 minutes

You should have replaced the spring clamps with the screw type clamps. There is a TSB that covers the size/part numbers.

The high speed fans (AC off) do not even come on until 102 centigrade. You are worrying too much. BTW the digital readout on the AC display does not agree exactly with the DME temp readouts I have taken. They must come from different source inputs.

My 99 996 after about 30 minutes in metro traffic (avg speed 12 mph per OBC), OAT at 98F per OBC --> DME values (not AC diagnostics) shows 207F coolant temp, IAT shows 156F, engine cooling fan came on while plugging reader into OBDII port Dashboard gauge was around mid way on the zero

Make sure you really need to change the transmission. Tips do not frequently fail, but can exhibit symptoms of failure. I am not saying the shop doesn't know what they are doing, but just may not have that much exposure to Tips. It would be extremely hard to become an expert on Porsche Tip issues with very limited exposure. Are there any codes? CEL on? There are numerous things that can cause problems that do not require a new transmission. As an example, pressure regulator 4 can fail causing a CLC lockup not to work. This could be interpreted as slipping since the converter doesn't lockup as expected (about a $500 fix). Another example, if the brake light switch is intermittent, the automatic downshift does not work properly. Yet another, if a wheel speed sensor fails (P1710 right front or P1715, left front), then your tip shift buttons on the steering wheel will not work I chased this gremlin through wiring diagrams, fluid change, harness check, etc. Finally found it reading the OBD II section on Tip diagnostics, which is over 100 pages. After nearly a decade of metro traffic, I have only had the wheel speed sensor issue and intermittent brake light switch issue. You do have options for a rebuilt unit out there with the updated ZF parts. http://www.freddiestransmissions.com/html/zf_5hp19.html http://www.europeantransmissions.com/ http://www.drivetrain.com/parts_cata...smissions.html Please keep in mind, not all problems throw a light, but will produce a code. Codes that do not trigger a light : P0710 P0740 (note this code was thrown by faulty regulator 4) P1602 P1656 P1704 P1710 P1715 P1744 P1761 P1762 P1764 P1765 P1770 P1828 (short to B+ only, short to ground throws a light)
