In preparation for my first attempt at adjusting my Zeniths when spring finally arrives, I removed the AC compressor to give me better access along with the condenser. Although it blew cold air when I first got the car, I never used the AC and wanted to remove it eventually. I was planning on waiting until the spring to do this so that I could drive it to a garage equipped with a freon removal system. Wanting to confirm that there was any freon in the system, I loosened one of the joints and nothing happened; the gas had already leaked out. Getting rid of that stuff really opens up the engine bay - looks so much better!
You can see in the first photo that the breather hoses to the oil tank were reversed. I will re-install them the proper way, which will hopefully reduce the amount of oil that ends up in the air box. I will install a catch can to scrub the oil out of the re-circulated air, as suggested by wayner here on Pelican.
I also removed the cold air distributer from under the dash. Love the minimalist look in the cabin.
The spark plugs were removed to see if they can give any hints on the engine health and the carb settings. The plugs in cylinders 1,2 and 3 were as expected, suspecting that the carbs were set rich. I was happy to se they weren't oily, which hopefully means the engine is not too tired!
I was pleasantly surprised to see the plugs in cylinders 4,5 and 6.
Any comments on what the plugs indicate and what I need to adjust on the Zeniths would be very appreciated!
