Took my '74 2.0 to a car show yesterday about 40 miles away.
I took the back roads on the way there and by the time I got there the oil temp had leveled off at 230' - I am told this is warm but not cause for concern. On the way home I decided to take the interstate and after about 20 mi. at 75 MPH THE OIL TEMP HAD CLIMBED TO 260' (2200 RPM in 5th) So I got off this road and after a break to let it cool, I proceeded on the back roads keeping the R's above 3,000 at slower speeds but it didn't seem to help much. Made it home with no problem and a pull of the dipstick shows good, unburnt, clean oil. How concerned should I be and what should I look for? NOTE; ambient temp was 85' (IMG:style_emoticons/default/confused24.gif) Thanks in advance for any help. CHAZT |

How are you doing 75 mph @2200 rpm in 5th? (IMG:style_emoticons/default/agree.gif) That would be closer to 60mph wouldn't it? Not that I'd know. I don't run 5th gear at any less than 3500 rpm, preferably closer to 4K. Running at 2200rpm in 5th is a great way to overheat your heads and cause burned valves and/or cracked heads. That's a lot of air-resistance your car has to push through at that speed, and it causes a lot of unnecessary load on the engine with your rpm's that low. This isn't a water-cooled car, don't drive it like one. |
