My 63 Lark likes oil. You can tell where it's been by following the blue smoke trail.
I just fixed the valve stem seals over the weekend, which seems to have eliminated most of the blue smoke. Also, the 6 cylinder engine has a PCV valve that was totally plugged which might have helped cause the trouble. The car spewed blue smoke whenever I started it, whenever I was going down a long hill, and at speeds over 55 MPH. Number 2 and number 5 sparks plugs were black. The others looked good (nice and white to slightly grey.
I haven't driven the car far enough (or fast enough) yet to see if the oil consumption is good now, but it sure looks better around town.
The other thing I'm wondering about is the oil pressure. The gauge reads 70 pounds at speed. About the lowest it reads is about 40 pounds at idle when it's hot. After it's been running all day, the maximum pressure is down around 60 to 65 pounds according to the gauge in the car. This seems high to me. The manual (on CD) says the pressure should be around 40psi and talks about an oil pressure relief spring that should be check anually. I could not figure out where that spring is located, however, so I can check it. Can somebody explain where it's at??
thanks!
