Sid, I have a 2180 VW and use the inside aft head bolt and I think the temp is supposed to run around 230 - 280, or something like that. Steve Bennett can give you the exact number, or I can look in my manual and find it for you, if you like. I put it under the plug on my first KR, and found that to be very problematic for the washer on the sender. I just put it in and re-torqued the bolt, but it is never a bad idea to check the torque on the bolts. Do it when you are going to adjust the valves and then you can remove the rocker and do all of them. I have had them loosen up on me before.

One placement is at the sparkplug gasket (substituting for the sparkplug washer?). The other location is under a head bolt (exact head bolt varies). The sparkplug location would tend to have higher temperature readings than under a head bolt. Then there is the wear and tear from checking and changing sparkplugs. Does the sparkplug washer provide a better seal than the thermocouple washer? Is there any concern for how far the sparkplug goes into the cylinder using different washers? If I put the CHT probes under head bolts, would the entire set of head bolts need to be re-torqued or just the one bolt with the probe? Does it matter which brand of engine for the above considerations? Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA sidney.w...@l-3com.com Mark Langford wrote... ... I'd had the sparkplugs out and when I put them back in one of the CHT probes (which I noticed wasn't looking that good) got a little twisted and frayed. That allowed one of the sparkplug thermocouple probe wires to short, which makes the EIS a little crazy... _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html
