  1. I am traveling, and did not take a picture at the time. Can do so after getting back, if you give me an email. There are many ways you can make this tool (a number of designs are evident in the ones sold on ebay). I had a worn out diamond saw blade disk that was the same diameter as the tank ring . I then cut 4 pieces of 1.5" angle steel 3/4 " wide. One side of each angle was slotted 3/4 inch deep about 0.150 wide (to engage the raised ribs on the retainer OD). The angles were then spot welded to the disk 90 degrees apart. If you don't weld, bolts could be substituted. In the center hol
  2. When ever you get a crank with no start condition, please remember there are a couple somewhat unique design features to these cars. First, the Bosch ECU does not turn on the fuel pump relay (never) unless it is getting pulses from the crank position sensor. This means, if the engine is not turning under crank or run conditions, there is no fuel pressure. This is intended to help prevent engine fires. So, if the engine will not start, you have to do the old fashioned check for fuel and ignition. Since these cars do not have fuel pressure sensors, the OBD will not be any help here. Pull
  3. I would like to pass along a recent experience that may help explain a lot of erroneous fuel level indication issues. My 986 has always been in the South, and subject to long periods of storage. The fuel level indicator moved in large increments rather than gradual change with fuel consumption. When the sender was removed for check out, the float arm was found to stay in any position it was placed in (could not fall of its own weight). Closer examination of the steel rod that the arm is made of, revealed a uniform layer of tan colored oxidation over the entire length. The arm can be pulle
  4. We sold a bunch of the production "no suspension dismantling required" bearing tools to various DIY mechanics. But the pro mechanics did not like the fact it pulled only the smaller bearings used in the Boxsters, and 996 front wheels. So,..... we redesigned it to pull both front and rear wheel bearings of Boxsters thru 04, and 996 thru 05. Now all configurations of these cars can be serviced with one tool (regardless of FWD, RWD, S model, or base model). You can see it on Ebay with a "Porsche wheel bearing puller" search. This tool is less than half the cost of a shop replacing just on
  5. We have been away from this forum for a bit, because you folks have been keeping us busy. We sold the 76th bearing yesterday, and have had to double the manpower assembling bearings. We are shipping dual row and single row bearings, as well as pullers and drifts for the same. We direly need to update our ebay listings, and get an alternate supplier qualified to make IMS support studs (for those of you that have run the assembly to complete destruction). So far no one has needed a stud replacement, as all the bearings have gone into engines that had serviceable bearings or very early failur
  6. Some really good, informed discussion here. It is important to note that the updated IMS bearing supports with the wider 3 rib seals also have very significant seal MATERIAL change. The early black o-ring seals are made of buna rubber. The 3 rib are orange (silicone). If you are using synthetic oil(which everybody should if they can afford it), the buna will eventually soften to the point where it will not seal. On conventional oil, silicone rings of similar size will take a compressive set in less time than buna, but life expectancy under synthetic oil is still worth making the material c
  7. Your 99 came with a dual row bearing. Check maint. history to see if it is still in there. There are so many factors involved in oil selection, I would not dare make a quick comment on what is "best" for your application. All the major oil companies have lube chemists or applications engineers you can speak with. Get in touch with them. As a general comment I can say we are fortunate to live at a time where so much really great oil is readily available. Any mineral oil (coming from a top oil company) with an SG rating is going to be 1st class. Likewise the top synthetics. Synthetics are
  8. Thanks Loren, The B90 is a very popular tool with the Porsche community,.... high quality. BUT, we have taken it one step further by eliminating the need to pull axles/hubs/compress and partially remove front struts to get the old bearing out and new one in (req'd with the B90). This will save the amateur mechanic about 4 hours (pro...at least 2hrs) on a front bearing,.... with no need for additional tools (spring compressors, joint separators, etc.). The B90 is usable on different make cars. Our first tool will work on base 996/986 front and rear wheel bearings (exact same bearing). Th
  9. Oops! Should have mentioned......the tool also has built in capability to re-install the new bearing. BR
  10. Here is the prototype puller with the bearing just about out. It is rough looking, but the production tool will be professional grade. This is a very robust puller, and will pull hundreds of bearings if used properly. Don't ask to see the mechanism, we will not tell you. Sorry, if you want to see how it works ...you will have to buy it Bill Ryan
  11. Early wheel bearing failure (40K miles or more) is pretty common on these cars. Just did one of mine last week with 45k. The 30MPH range is typical of when the noise can be heard inside. If the noise is independent of if the clutch is depressed or not, it is probably a wheel bearing. It is usually pretty easy to audibly tell which side the problem is on, but determining front to back is more difficult (at least on my Boxster). W/o the front wheel drive, you can remove the wheel and brake pads (5 min.) and spin the hub. If noise or roughness is felt, you found it. If you think it is gone, b
  12. On the subject of mechanic qualifications for installing the hybrid bearing kit.................. If your mechanic has personal experience doing Variocam actuator replacement, has renewed the chain guides both on the Variocam actuator and in the crankcase, has removed and replaced all the three (totally unique but unfortunately interchangeable) chain tensioners, has sequenced and timed the camshafts on both banks, and has field serviced an open bearing or two in his past............then he is qualified (he understand how this valve train works). If he says " I've done it on a Toyota, same t
  13. Thanks Loren, hope this can be resolved as I do not like letting people think they are sending messages to a vacuum! All personal incoming messages thru the Renntech system are in miniscule text regardless of which of my 3 computers I am using. To read them I have to forward the message using my regular JUNO email. When the forwarded message opens, it is in my usual text size. However,.........any links in the original message will not open, making a reply impossible unless the writer has included a direct email address. This situation is completely unique to Renntech correspondance. T
  14. Mike, You sent me a direct message thru the Renntech system, and I could not reply because the text size would require a microcope to read it. I have written to the webmaster, but the problem persists. Please send me a direct email at N1WR@juno.com On your requests above.............our position with this bearing replacement is that it is a job for trained, skilled, mechanics who already have experience with major repairs to these specific engines. There are so many unique construction features and special tools required for these engines, that the chance of a novice installing one w/o
