  1. I put the wrong one up. This is the correct one. Sorry http://www.carburetion.com/Weber/webernumber.asp?Kit_Nbr=99004.731
  2. Seems a little pricey but. http://www.carburetion.com/Weber/webernumber.asp?Kit_Nbr=99004.110
  3. I agree Here is something from Mobil Mobil Technical Bulletin Mobil Oil Australia Limited Automotive No. 863 WHY DO WE CHANGE OIL? Some machinery, for example steam turbines in power stations, does not require oil changes, the original charge being usually expected to last for the life of the machine, which may be 20 years or more. Why then does the oil in a motor car engine have to be changed at regular intervals, which may represent only about 50 hours running? To answer this question, it is as well to state that except under very unusual circumstances, oil does not “wear out”, “break down” or otherwise deteriorate to such an extent that it needs to be replaced. What happens is that it becomes contaminated with water, acids, burnt and un-burnt fuel, carbon particles and sludge so that it can no longer provide the desired degree of protection for engine components. But, it will be argued, most modern vehicles have an oil filter. Why does this not remove the contaminants? The answer here is that a filter can only remove solid particles above a certain size. It cannot remove water, acids, or fuel dilution, all of which pass through the full-flow filter just as readily as the oil. As we have already seen, the oil contains additives to combat the effects of these contaminates. But there is a limit to the amount of contamination that even the best oil can neutralize, and there comes a time when the only satisfactory procedure is to drain the oil and replenish the engine with a new charge. Thus there arises the necessity for regular oil changes. The question should now be asked “How often should engine oil be changed?” Unfortunately there is no simple answer to this. From what we have already discussed, it will now be apparent that we change oil, not because it has deteriorated, but because it has become contaminated with various harmful substances, and the greater the rate at which these enter the oil, the sooner an oil change will be necessary. The things that influence this include engine condition and method of operation. A vehicle that is used mainly for short distance stop-start running will require more frequent oil changes than one used for regular long distance traveling, and a worn engine with leaky piston rings will contaminate the oil quicker than a new engine in good mechanical condition. Thus it is not unusual to specify oil change periods in terms of numbers of miles or days, whichever comes first. It should also be borne in mind that a high performance product like Mobil 1 can handle more contaminate than other products, and hence longer oil change periods can be justified. As a final comment on this subject, it is worth mentioning that it is normal for oil to darken in service. This is not an indication that the oil has deteriorated. It shows that it is picking up its load of contaminates and keeping then in suspension, where they can do no harm, and where they can be removed from the engine when the oil is changed.
  4. Oil dose not break down!!! Oil gets contaminated if you keep it clean it will last a life time. There is a diesel Tugboat running around the Great Lakes I forget her name, that has the same engine oil in it since it was put into sevice 1953. The filtering system they use cleans the oil down to less than 1/10th of a micron. All they do is add additives that are recomended after testing.
  5. Sounds like they want you to change your oil at 5,000 miles to me. My 86 Ford diesel says 5,000 normal and 3,000 extreem, Which they say is towing or dusty conditons.
  6. I guess what I was asking. What dose Kia call extreem?
  7. Not if you get the oil up to operating temp. and drive it. If you drive 3mi to work and back and never get the oil up to operating temperature and yes condensation would be a problem. As far as contaminants, if you use a good high Quality oil and air filter and keep the oil clean, there is no need to change the oil that often.
  8. I don't know what extreem condtions means to your Kia, but if you go to a oil change place they always say "we recomend you come back in 3,000 miles" and put that little sticker in your window to remind you.
  9. Why is 3000mi the magic number, because the oil change places and and filter companys like Fram say so, even if the car companys state a longer oil change cycle. Why, because they are selling the stuff. Most people in the world don't change there own oil. So let's say you take your car to a oil change place every 3000mi. And you keep your car for 100,000 mi. That's 33 oil changes. But if you change you oil by the book at 5,000 mi. That's 20 changes, so how much extra money did the oil change place make.
  10. I guess what I'm trying to say is, if you keep the oil clean by filtering, it dosn't matter which oil you use Dino or Syn. The oil will still do it's job long after you are changing yours.
  11. I've looked and looked and can't find the ratio. Someone has to know or have a book or something that tells.
  12. Dose anyone you know the rocker arm ratio of a EA81?
  13. It's your money. But did you read this? http://neptune.spacebears.com/cars/...s/oil-life.html
  14. .700mm is about 1/2 the thickness of a CD disk, I don't think it would cause a problem.
  15. Unless you are running Alcohol or methenol for fuel, you wasting good oil. It would make more sense just to change the filter at that low of mileage and top the oil off. you could go on for ever without any worries.
  16. Wouldn't you use them to mount the hubs to the trailing arms? Using beveled washers you could change the camber, toe-in toe-out. If you were going to race your Suby on a round roundy track, you could adjust your rear tires to lean into the corners better.

  18. I don't know what kind of mount it has for a winch, but here's a cute little one. http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=91727
  19. It's not just the oil they use to get that kind of mileage between oil changes. Amsoil also recommends that you use their oil By-pass and air filter system, similar to the systems used on big trucks and heavy equipment. I operate heavy machinery and they change oil every 200-250 hours and that's using Dino oil. Now these machines run wide open most of the time in far more dust and dirt, than the average auto does. So how far could you travel with your foot on the floor in 200 hours? Like I said before, if you can keep the oil clean, it will last alot longer than 3000 miles.
  20. As long as you keep the oil free from impurities, there is no need to change it.
  21. Your version works just fine. What I like about the one I posted, you can print a hard copy of just your car.Craven
