This topic is about what happened to a friend of mine while driving back home from his holiday. On the final leg of his journey, the car started to lose power each time he tried to go over 50 mph. Then the engine had begun stalling and the car was shaking violently each time. Long story short, he called for my help and I towed him home for the last 10 miles because the engine went into a no start mode. Before towing him I checked for the no fuel condition and sure enough the fuel pump was dead (bought new 3 months before). His car is similar to mine, 1.3 liter on carburetor, it has a mechanical fuel pump. So anyway, back home he put back his old fuel pump and the car started right away. BUT... And here comes the part I'm not really sure what's wrong. There is an audible, quite loud knock at idle in sync with engine speed coming from gearbox end. Most probable it is related to numerous shocks that hammered entire transmission for the last 200 miles. See photo below where I indicated where the noise is loudest. The knock disappears when the clutch pedal is pressed. I have to mention that the knock is not the classic random rattle often heard on Felicia when gearbox is cold coming exactly from the same area. It is a constant, louder knock. What I can say for certain is the knock is related to gearbox input shaft. I can further guess the bearing of input shaft is faulty, but I've never heard a bearing knocking is sync with the shaft speed. That is why I need your opinion.
