had some problems with my 1.6i gls mk3 astra this morning, basically it looks like there are fumes escaping from the manifold near the engine at the front of the bay.
my question is, is this something that needs serious attention? will it damage the car to leave it? if so, short of replacing the manifold is there anything else i can do in the meantime to fix it? the smell of exhaust fumes in the cabin sets alarm bells ringing in my head even when i know where they're coming from lmao
