I'm pretty amateur at all this. Are you saying that this is normal and I shouldn't be too worried or that it is common problem that happens that needs to be sorted out asap? It's a 2005 Focus with about 147,000 on the clock, so it's not old but not new so I'm unsure what you mean by "new" Fords.
I'm seeing answers on other forums that it's nothing to worry about, and then on others I am seeing answers that say my engine will basically blow up.
If it needs to be fixed, what is it that I need to ask the mechanic to fix (but in simple terms so that I can understand what I'm asking as well).
Thanks again, really appreciate it.
