The oil dipstick was starting to get very rusty due to the excess heat from the manifold, so rusty, it's starting to break in half! Before it happened, I decided it was time to replace it with a new one, coated in Very High Temperate Paint to give it extra life.
The oil dipstick tube part number is FINIS 4346328

With the Very High Temperature Engine Enamel Paint, it should keep the dipstick tube free from rust and also it's easy to clean. Result! :D
