Would you consider the camshaft oil seal to be an internal engine part?
I am sure some would say it is and others would say it isn’t. The others would be the warranty company looking to avoid paying.
One could argue that the oil seal can be changed without the need for opening up the engine. However the timing belt has to be removed along with the back cover. So if the timing belt is considered an internal engine component then the camshaft seal would also have to be considered internal.
My opinion is the camshaft oil seal is an internal engine component. I am basing this opinion on the replacement procedure of the oil seal itself according to the auto repair manual procedure. The new camshaft oil seal is to be installed first and then the camshaft into it. This means the camshaft needs to be removed before hand. And there is no denying the camshaft is internal. I will ad the auto repair manual procedure so you can get a better idea of what I am talking about.
