The worst situation is when stopping for gas or becoming stalled in traffic on the highway after running at high speed. On those occasions when I do drive in cooler temperatures the temperature usually reaches 75 - 80 degrees C (167 - 176 F) even without a thermostat although the warm up is a little slower. The advantage of running at this cooler temperature is that the system seems to have a larger "reserve" when the above traffic problems occur. I found that the indicated temperature (which is accurate), runs 5 degrees C higher even when using a 165 degree bellows or wax pellet type thermostat. I suspect this is due to the slight restriction even when the thermostat is fully open.

Very frustrating as the car runs so well with good oil pressure and compression. After many months of tests and checking have established that the block on my BJ8 has the porosity issue. This is not the well known oil into water but water into oil. (after 1000 mi, 3300ppm into oil) I did find an area behind the center tappet cover where water was oozing into the drain back from the rocker. Did my best to repair it with epoxy from the outside. No doubt it is leaking there or some place else. Fellow lister Wayne Schultz had the identical problem. My query is if there is a known solution to this problem ? resin impregnation ? or maybe a modern treatment ? Also have located some replacement blocks but how to test ? and be assured that these old blocks also don't develop the same problem ? Changing blocks invariably means a complete engine rebuild. How common is this ? All very painful. rg -------------- next part -------------- An HTML attachment was scrubbed...
