Manuel, Have you tried using the broken off top half of the original bolt. If you press real hard and turn the bolt as if you were removing it, this should extract the broken off piece. I have done this with success on head bolts that were deeply recessed as well as several other hard to extract bolts. What you need to realize is that there should be no pressure on the broken section, it is just sitting there. The only potential pressure is the o-ring on the bottom of the threads. Try this and let us know..... I have another super-trick if this one does not work.

Dog-n-Hog <[EMAIL PROTECTED]> has some very good information about the ICV and the pulse width modulated signal that drives it. I would add the following caution: According to Bentley, the proper setting of the ICV adjustment screw is with the engine at a base idle of 700-750 RPM (going from memory here) you adjust the screw on the ICV so that an ammeter in series with the ICV shows a draw of 400 ma +/- 10 ( again if memory serves correctly). You may ask, why is he being so particular ? Several posts in years gone by have addressed failures in the Idle Control Module (ICM) where a "post mortem" revealed failures of or related to the output transistor that drives the ICV. The consistent failure related to the fact that the transistor has no heat sink, and that there were what appeared to be failures due to excessive heat from that transistor which translated to burned traces/failed solder joints to the output transistor. My own experience is that changing the setting on the ICV adjustment screw does indeed change both the idle and current draw. If 400 ma is the design state of the ICV current draw, I can foresee two sets of circumstances that would lead to failure of the ICM: * You set the adjustment screw to try and play with the idle speed so that the ICV draws excessive current that causes additional thermal stress on the output transistor that gets conducted down it's leads to the pcb to which it is soldered * As the ICV gets worn and or gummed up with oil and dirt, it's response to the pulse width modulated driving signal starts to lag. This causes the system to try and compensate and I can see that changing the current draw of the ICV ( greater or lessor, I don't know, but if greater - --- ). As above, this increases thermal stress on the output transistor and it's solder points and traces. Since power can be calculated as being equal to the square of the current times the resistance [a transistor in it's "on" state has a small internal resistance - which in combination with the current being passed through the device dissipates power in the form of heat, hence the "dissipation rating" of a transistor] , a small change in the current draw of the ICV can have significant heat dissipation effects in the driving transistor which is passing/controlling that same current - without a heat sink. [example, the power dissipation at the design state of 400 ma. is 0.4 x 0.4x R = 0.16R watts. If the power draw increases to 50% to 600 ma, then the power becomes 0.36R watts -- that is a 225% increase in power/heat dissipation! ] Harvey - I live with fear, death, and evil...but I used to be able to turn it off and use a Mac.

Game officers, game wardens, Dept. of Fish and Wildlife, whatever they are called in your state, have more authority and powers of arrest than a sheriff, police officer, or even state police officer. Think about it, they have no jurisdictional limits to contend with. The state line is their limit. A police officer cannot cite you for fishing, hunting etc. whereas a Game officer can, as well as speeding etc. They do not cite for speeding unless you are a moron and pass one of these fine officers at warp9. Don't ever take a game officer for granted, they can do more damage than a normal officer if you are asking for it!!!

HuH? Unless I'm totally confused, 225 vs 205 represents the nominal width of the tire at the side wall. Nominal being the operative word, as tire manufacturers round these numbers in bizarre ways. How much tread is actually on the ground varies also but usually is related to the sidewall width measurement. A 225 tire is usually about 20 mm wider than a 205 tire at the sidewall and at the tread. The 45 vs 50 of the second number is the height of the tire as a percentage of the width. A 225/45 is roughly 225 mm at the sidewall slightly less at the tread and 101.25mm measured sidewall height. 205/50 is roughly 205mm at the sidewall width slightly less at the tread and 102.5mm measured sidewall height. www.tirerack.com has some good explanations and drawings of how all this works.

I do know for the kind of driving most of us do (i.e., driving schools, etc.) the more mass in the rotor the better for heat dissipation. But the difference in price was only $2 so I figured why not buy the gimmick ATE's At the time I did not know that suppliers advertising on this digest carried Baylos which I would have bought without hesitation based on previous experience with this aftermarket supplier. I ground down many pads on my Baylos before I had to replace them after over 150,000 miles. I would never buy cross-drilled rotors and I probably shouldn't have bought the slotted ones but I knew I was going to sell the car and they did look kind of trick. I figured the new owner would never know or care about the truth of slotted rotors (less mass).
