Hi, I want to know if I have ordered a cheap valve spring and it will break again. I replaced a broken valve spring with Empi high performance premium steel valve spring. I will only be replacing the one that is broken. I have a 1962 vw bug with a 1914cc , the spring that broke is a steel spring not sure if high performance or not. Also what type of oil should I use in the engine and what type of oil should I use in the transmition, its a 1967 swing axel 4 speed stick. Thanks............. :-)
