  • You may try running the car with a big house fan in front of it and see if this makes any difference.(sitting still or get a really long cord)Ha

    • I just took off the new water pump to check the impeller and it was fine. I'm starting to wonder if i have a head gasket issue.

      • Hope not. Anything in the oil? It'd show there by now if so. =/

        What's conservative advance on the MSD? What is your initial and idle advance? I'm wondering if it needs more advance at lower speeds.

        • With getting derby motors hot often, we can tell if a head gasket goes by the water going out the exhaust.. To be honest, our exhaust goes straight up.. Can't say which side is prone to going.. Seems even on both sides..
          Maybe remove your exhaust at the collector and run it to see if some comes spitting out.. You will get a damp hand when you pass oy over the collector

          Water does not always go in the oil when a head gasket goes..

          • Run it long enough, it goes by the rings and into the oil, especially on shut down. Granted I've only seen a handful of blown head gaskets, but every one that impacted the cooling system had water in the oil.

            • Nothing in the oil yet. Timing is set to about 10-12 degrees at idle. I think I'll pull the plugs and see if there is anything interesting.

              • If it's not in the oil check the exhaust for more than normal steam and a sweet smell. If not warm it up and use a radiator pressure tester and see if it holds pressure if it does it may not be the problem let it set for awhile with pressure on it. If you don't have one I think Auto Zone has a loaner.

                • I pulled the plugs under the theory that if I have coolant getting into the combustion chamber I'll see a clean plug. Here are the passenger side plugs. The drivers side were no different.

                  • After that I decided to switch the thermostat again. This time i used the old high flow 180 that was in the enginge 6 years ago. Took it for a test drive and after it heated up to about 220 it started to come down. I drove it at least twice as far as this morning and when I pulled into the garage it was reading 185. I even let it idle for a couple of minutes and it held steady. I'd like to be happy about this develeopment but I'm too busy being confused.

                    Here is a question to ponder: If this really was the problem and my luck is bad enough to buy 2 bad thermostats, should I be driving an old car like this accross the country and back?

                    • Reliability is boring

                      I find the odds improbable, but you never know.

                        • Just took it for another drive and after a blip to 215 it behaved fine.

                          At this point, with 68 hours until we leave for the Power Tour and 3,800 miles of travveling across the country, there is no way I am going to be comfortable taking this car. There are too many untested systems the temp gremlins seal the deal.

                          Here is our ride for the tour this year:
