Getting Ready for the Road.
Just bought the car, going to do an all around maintenance on a 1971 250C.
But I have questions..
spark plug recommendations? Your favorite with part number if possible.
Oil Recommendations: I know.. opening can of worms. I used Castrol GTX racing oil in my 928S because of the high zinc levels. I had 15-40 recommended as a weight from the previous owner in Colorado. I live in Rockford Illinois about an hour and a half NW of Chicago.
The car has some strange looking plug wires, pic below. Bosch Brand. I looked at them in the dark and they are not sparking on the outside, but I am getting a random miss when hot, replace? Problems with the Zenith Carbs also, so it may have little to do with ignition.
Getting coolant out of the water pump weep hole, so that has to go, will replace all belts along the way.
All replies are much appreciated Sirs! Gary
