Hi guys, wonder if anyone can help me out a bit
Just bought an S3 only to have the oil pump fail within a week. I foolishly drove the car about 300m after the oil pressure light came on to get it to a nearby garage. The engine sounded tappety and clearly wasn't behaving.
Garage (Ford) weren't keen to look at it so i towed it home and took off the sump to find that the oil pump chain had come off the oil pump sprocket - turns out the metal ring of the baffle had got wedged between the two and bent the sprocket. The chain had clearly been running despite this and had mashed up the pump somewhat.
Worried about having siezed the engine i tried to turn it by hand using the crank pulley - i managed to turn it half a cycle but it was tight.
I replaced the oil pump, pick up oil filter and oil and sealed it all up totay hoping that would be the end of it - but when i went to turn it over it the following happened...
First attempt sounded normal just didn't fire the engine - all good i thought
Secont attempt and i heard a pop noise and saw smoke coming from the top of the block, went to look ant it looked like it was coming from the coil and there was a smell of burnt oil.
Engine now turns over too easily and doen't sound right - like there's no compression and it won't fire.
I'm out of ideas - can anyone shed any light on what might have happened??
