There really isn't any really good place to do this on the type 3 engine. If you can seal around it, sticking it in place of the oil pressure switch would be interesting. If you have the 72-3 heads (doubtful) that had the breather tubes, you could stick it down that hole. Don't stick it down the breather pipe: It's likely to get caught up in the cam gear. 8-0 > Also any temp specs that I should be reading would be appreciated. Oil temp? > cooling air temp? any others? Berg claims that oil temps above 212F indicate trouble. I suspect that 180- 200 should be "normal." 212F is convenient since it is easy to check the calibration in boiling water. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
