any idea y my mondeo si is knocking??
Discussion
my si has started knocking outta the blue. its a top end knock and only seems 2 do this between 2500 and 3000 revs she also knocks quitely on idle. we've changed her oil and filter as it was dead but its still there although a little quieter now.
Anyone got any ideas?
Does she have hydaulic lifters shes on a L plate? could this b the prob?

Just a thought, grab a long handled screw driver and use it as a stethoscope, have a listen around and you may pinpoint it. It could be something as simple as a water pump bearing going.
...or the alternator. How's made a slight knocking noise before it went and it was so bad when it did go that the AA man recovering the wife thought it sounded like the big ends had gone until he spent a good while pinpointing the source to the alternator which had shattered its bearings. Running the engine without the aux belt will discount the alt, pas and aircon. Disconnecting the water pump belt (for a very brief perdiod) will discount that.Gassing Station | Engines & Drivetrain | Top of Page | What's New | My Stuff
