For all you 2.0 d-jet folks....
Look at your throttle body plate (the valve that closes over the TB opening). Does your valve have NO hole in it, one small hole, or does it have a nut and bolt in the hole? See three samples below. The third photo doesn't show the small hole plugged, but you get the idea. It is like the second with a nut and bolt plugging up the hole. Bonus question: What purpose does the hole serve and why is it closed on some TB's? (IMG:style_emoticons/default/beer3.gif) Thanks, Len PHOTO 1 NO HOLE: PHOTO 2 SMALL HOLE: PHOTO 3 HOLE PLUGGED - THIS PHOTO DOESN'T SHOW IT, BUT JUST IMAGINE THE HOLE IN PHOTO 2 IS PLUGGED WITH A SMALL BOLT AND NUT. |

OK
Someone must know what the answer is as to why some valves have a hole and some do not. I found this photo of a bunch of TB's in a old post. They apparently came from a shop that would replace FI with carbs and had these throttle bodies as scrap. Note some of them have a hole in the valve plate and some do not. I'm puzzled as to why that is. I don't think those with the holes were drilled, they look like they came that way. (IMG:style_emoticons/default/blink.gif) Anyone? |
