Just put a new VDO cylinder head temp gauge in during the off-season (after getting scared that the oil temp gauge was off, though the car runs like it's new). After driving it around for a couple of days I have the following results (with Mobil 1, 15W50, in a '74 2 liter):
Oil temp on factory dash gauge - barely reaches the "T" after full warm up and no matter what rpm I'm at. Cylinder head temp - around 300 driving around town (never gets beyond 325, even in traffic, such as it is in Kalamazoo); around 400 on the freeway @ 3200 in fifth at 75-80 mph I thought the oil temp and cyl. head temp would be roughly equivalent, at least as far as I can figure from the past threads. The big difference has me stumped. Anybody have any explanation? Am I going to hear any expensive noises soon? What numbers should I be looking for?
