Thank you Advisor Guy and (again) Brian,
Brian,
You were right - At least 2 of my plugs were shot, probably 3. Since I already bought 5 from the Dealer rather than by mail (hoping to complete this quickly.. ) I just decided to go with the Bosch, as were there originally. First 4 came out with some effort - last one behind the oil filter is a bear and I think the nut is stripping.... I tried all of my 12 mm wrenches (a regular, a ratcheting one, and my 12 mm socket won't fit due to clearance). I also sprayed some blaster. I believe this one is shot, too, and I want a new one in there. Any suggestions on how to get it out? May it be needed to actually remove the oil filter housing
? Advisor Guy, your idea of removing the throttle linkage is a good one, but I don't think it is enough now that this is stripping. Are there any ideas on how to remove this nearly stripped old, dead glow plug? Many thanks!
