 Oil filter housing
Well I was ordering the parts to fix my filter housing leak when I noticed in the diagram that the filter cap shows to have a spring on it. The diagram I was looking at was on realoem.com. I know mine does not have a spring on it from doing the oil changes, but up until now I was not aware there was supposed to be one. Am I looking at the diagram wrong or is there really supposed to be a spring on the inside of the filter housing cap? |
