I found this pic on the web, and trying to determine the what part it is (in the yellow cloud)
Also - what is going on with the oil stick? Has this owner shorten the stick and tube? (pink cloud)

Wow you guy's provided awesome feedback!azruss wrote:the cover in the yellow square was the distributor location on the 1438 cc block. Future models moved it above the exhaust manifold and the the hole was covered. I added a computronix ignition and moved the solid state distributor back to that location and moved the plug to cover the upper location. I also removed the long dipstick and modified it to fit the hole as you see in your picture. The long dipstick was interfering with the dizzy. This cleaned up the top of the engine and got rid of interference with the hood and spark plug wires. this also got the solid state dizzy away from the heat put off by the exhaust manifold. Finally the upper dizzy location was prone to drip oil on the exhaust manifold. Got rid of that issue as well. Since the solid state dizzy does not require any maintenance, the lower location is perfect.

The dipstick used is an early one. Based on your timing cover, you have a 2000 carb motor and it should have a long tube with long dipstick or you have a late 1800 and that should also have a long tube and dipstick. The 1800 used a tube nut to seal to the block and the 2000 used a rubber seal.
