Possible engine probs
My 33 has started to run a little rough. The problem started when I discovered that a pipe running from the bottom of the throttle body to the oil filling point had snapped off on the oil filling point connection. seemed to have lost a little oil before i temporarily repaired connection a fitted new hose. topped up the oil using selenia 2k as recomended by an alfa garage. Then the noise starts about a week later, sounding slightly tappety and very laboured. I have seemed to have lost some power to. Anyone out there got any ideas?
Thanks in advance
P.S. Any idea on what the pipes purpose is?
