  1. 1. The Ctek 3300 does get warm when it is charging, but cools when it gets to full charge. All Ctek units have built in overheat protection that will reduce output or shut the unit off. 2. The fact that the mode control button does not move the setting to the car icon is a problem. Do either of the 1/2 battery or full battery indicator led's come on? You are supposed to connect the unit to the car first (cigarette lighter or alligator clips) then plug the unit in and try to set it to the car mode. If you cannot, it may be an indication that either you have a bad battery ground, p
  2. The windshields that cause interference (blockage) of radar signals use a thin metalized film imbedded between layers of the glass. Typically, these windscreens have a slightly golden metallic sheen if looked at on an angle in bright light. Because of the metallic film, the radar waves are reflected and never reach the detector mounted inside the vehicle. Several manufacturer's use this technology as they can pass a low voltage current through the entire glass surface rather than just in localized areas, improving the deicing. If the heated windshield option uses this method, it will bloc
  3. The power steering systems in these cars suffer from a couple of issue; first, the reservoir volume is too small and in a location where it is seldom looked at (even worse in a Boxster or Cayman); and second, due to how the system is packaged, they tend to overheat. Street cars typically do not suffer a lot of problems unless the steering reservoir was allowed to run dry. Track cars suffer a lot more due to accumulated heat. In either case, once steering pump noise or issues develop from heat and/or low fluid levels, nothing can be done to save it, component replacement is on the horizon a
  4. If you have ABS, you need the PST II/PIWIS because you probably have gotten air into the ABS control system with the master cylinder swap out as the Motive system forces the air downward into the system...........
  5. Normally, a bad AOS will have an unusually high vacuum in the sump. Try removing your oil filler cap with the engine running, it it is difficult to get off, you have a bad AOS.
  6. If I'm not mistaken, wasn't this issue recently written up in Excellence magazine? If it is, they came up with a welding solution that is supposed to be a permanent fix............
  7. Exactly, as stated earlier, the very early cars had an adaptor plate, which is what yours is; the later "S" cooler will still bolt in, and as Loren pointed out, is the only style replacement cooler available.......... As for the coolant, if the system is not drained prior to pulling the cooler, it will dump about 2 liters of coolant all over the engine, and some will most likely go down the oil passages. Removing the vent line will not cause the system to drain down; the cooler remains full of coolant when the engine is not running............
  8. The cooler is the only place coolant is anywhere near the fluid, it has to be the source.
  9. Actually, we do have experience with it, some with aftermarket conversion kits as well as with some of the OEM "Flex Fuel" setups, which I believe is what the OP was asking about, and what I based my comments on. So I would not say that my shop "doesn't have any experience" with the technology; we do, and it hasn’t always been as smooth or easy a route to cheap performance that some marketer’s would like you to think; which is also I also believe the OP wanted to know as well.
  10. Yawn......................... B) Look, if you are so "had up" about using E85, be my guest. I see far better performance pathways for these vehicles, with fewer maintenance headaches, than high EtOH based fuels, particularly on engines that are not normally aspirated, and definitely not those with DFI. In the end, it is your money, your vehicle, and your problem. Just don’t expect everyone to agree with your choices……….
  11. As most, if not all of the customers (and potential customers as well) that approach us concerning upgrades or modifications to their vehicles are fairly astute and reasonably well read on the options available. The read the usual performance magazines and post on websites focused on their particular make and model. As such, they have been exposed to a lot of potential modifications, and usually start by asking about the relative merit of “A” over “B” or “C” pathway to more power/better handling, etc. Very few come to us clueless about what they want or need to do. As for E85 availability
  12. Just so we are clear: We hear about extensively modifying Porsches everyday; along with our Merc, BMW, Ferrari, and Maserati customers as well; and with our domestic crowd. Not one has brought the subject up. Upgraded turbo's and associated gear, headers/exhaust systems, cams, reworked heads, intake manifolds, injectors, throttle bodies, total upgraded engine swaps, computer re-flashes, even the occasional nitrous set up; but no E85. Perhaps at the "complex carbohydrate adolescent" shop across town, but not here...................
  13. I think he wanted to have metal flakes checked, not oil, to reveal the exact alloy. In any case, he will need a metallurgic lab to determine what the alloy is, and I do not know of one that is “Porsche specific” and able to tell you where the alloy came from; that is simply way too specific. I think any decent metal lab can do the alloy break down, figuring out where it came from would best be addressed by someone that spends a lot of time building there engines from scratch......
  14. "Fuel lines would only need to be changed if they are aluminum (most cars are not, nor is the fuel tank usually aluminum.)" And how many OEM's are using "aluminized mild steel" fuel lines these days as a hedge against situations when water gets into gas due to E10? More than you might imagine....... "Ethanol is proven to make more horsepower at the same volume of air flow if enough fuel can be supplied. " Sure, if you pump enough EtOH into the engine, eventually you overcome the simple physical fact that EtOH is down 1/3 on specific heat output (read horse power) on a volumetric basis w
  15. Usually, someone familiar with wheel bearing noises on these cars can spot a bad one quickly once the car is up in the air, just by turning the wheel and listening. Changing the bearing is not that bad a job but is made significantly easier using a specialty tool set like the SIR system.
  16. @JFP, Thanks for the input... I cut my filter yesturday after 1k miles. Still finding some flakes...less flakes based on only 1k miles. What the hell...I changed the oil while I was there. Drain plug shows no sign of decay or flaking. There are no PST or Durametrics in my area. I have considered the purchase of the durametric for my personal use... If you strongly believe I should plug in and watch cam deviation on a regular basis... I will order one now... Let me know. The Durametric software is as close as you are going to get to having one of the $18K/year leased PIWIS systems
  17. There should be no resistance in the cables to and from the battery.
  18. Magnetic drain plugs are used on everything from motor cycles to Cadillac's to race cars, and on engines, transmissions and differentials; they are a low cost tool with no moving parts that can help you assess the general condition of your engine, and sometimes help identify a developing problem before it becomes a disaster. Not bad for a couple of bucks.....
  19. What you may want to look at it the resistance (ohms) in the battery cables. From time to time we see a car with apparent charging problems that are actually caused by high resistance cables due to internal corrosion or bad connector ends
  20. Going on a population of two (the ones I have personally seen) yes, but with a caveat: I did not have access to the car's records prior to them coming into my shop, and both were multiple owner cars; so I cannot say if the car was factory original, or if they had been "updated" at some point. Interestingly, the engine oil cooler on the very early cars (without a vent line), is almost a dead ringer for the trans oil cooler still used on the Tiptronic transmission; both mount via an adaptor plate, neither has the vent line. I have often wondered if they were the same unit, but have never ha
  21. No modifications? How do you seal the oil passages without modifications? What do you do with that tube that does not stick out of the top of the 1997 (986) heat exchanger? Very simple: That is the very early 2.5L oil cooler, that uses an adaptor plate (attached to the cooler in the photo) can be removed and moved over to the newer cooler, which is flat on the bottom, with openings for the oil and coolant. These adaptor plates were only used on the very earliest 2.5L motors. The later cooler will still fit, and this is exactly why most dealers seem to sell you more o-rings than you
  22. I would expect a more granular ferrous material, and a lot more of it, if it were the IMS bearing.............. That said, there are no "good" metal finds in the oil filter, and I'd keep an eye on it. Just to be safe, if you have access to a Durametric system, or a PST II/PIWIS unit, take a look at the cam deviation values at idle, if they are steady values the IMS is probably OK at this juncture.
  23. Sorry, but that is not correct. E85 has a tendency to cause corrosion due to water entrainment in the fuel, leading to severe problems with injector, fuel lines, and components such as the pump, which also may not be able to deliver enough E85 fuel to begin with. Most to the seals and o-rings in the fuel system that are meant for gas will also tend to swell and leak, leading to additional issues. We have seen more than one "attempted" E85 conversion in the shop, most of the aftermarket kits simply do not hold up because they do not go far enough. As far as making more power and costing
  24. So what? The part number designates it was for the "S" Boxster or the Carrera's, but it still fits as the mount on the engine case is exactly the same on all three cars. It is taller than the base unit, but that is why you want to use it: It has more than twice the heat transfer capacity. It fits, without any other modifications, and it works.......
