Driving one of the cars (2.0L with dual carbs) and see a consistent 230-240F on the dipstick temp gauge. The gauge is accurate (tested in boiling water). Normal driving.... 90F day, mixed speeds with 60 to 70 mph max, flat terrain.
The PO had pulled the tins to repaint them so I assume mice nests are not a problem. I will check the oil cooler and the bellows this weekend; however, I don't expect any issues there. So, other than investigating to see if there is a lean condition with the carbs (which impacts CHT more than oil temp...correct?), It looks like my options for remediation are limited to an oil cooler. I've done a search and find most threads are for 6 conversions or homemade setups. Of the few kits available, is there any consensus on a good affordable solution? |

The cheap narrow-band O2 sensors will tell you almost exactly NOTHING. They kinda suck unless you're trying to keep a car with modern digital EFI in the mixture range that lets its catalytic converter work the best (and minimizes pollutants).
You need the wide-band O2 meter if you're going to try to check your mixture. I will echo Mark Henry's comment above about "Assume nothing." I wound up with a couple of paper towels in my fan a month or two ago which caused very high oil temps in normal driving. And any time the engine tin has been apart, it is possible for the flaps to get left out "because they just get in the way", or for them to get stuck and not able to open fully. I recently installed a large Earl's cooler, together with their t-stat and "sandwich" adapter. I put it under the rear trunk floor, figuring that a larger size would make up for a poorer location (than the nose of the car). It does, but not completely. See my "will it be done before Parade" thread for pics of what I did. Oil temps still got to 240F up around Reno on a 100F+ day at 75-85 MPH with this setup. I backed off down to 65-70 MPH and the temps dropped to the 225F range. --DD |
