Re: Alfa 145 cloverleaf smoking.
Blue smoke on over-run indicates worn rings and in general, as said above, a worn engine, my old QV use to do it, in fact before i uploaded one of the videos you could see it as i changed gear and let off.
If your mechanically minded and have all the right tools, spend around £300 on parts, get new big end shells. . .trust me, i taken to bits 3 2.0ts's now and all the shells were shot on then, the mains will be ok, change the rings, belts etc.
Its not going to stop you dead if you continue to run it, but it will gradually get worse to the extend maybe where you dont have a great deal of compression.
The only thing that i could possibly suggest to make it last a bit longer and perhaps help it in the mean time, is to treat it like a new engine when bedding the rings in. I snatched this from the puma race engines website.
"Now you're ready to take the car out on the road and bed the piston rings in. To do this requires several brief applications of full throttle in a high gear to generate high cylinder pressures and force the rings against the bore walls. Put the car into 4th or 5th at 1500 to 2000 rpm and apply full throttle for about 10 seconds. Coast along for 30 seconds to dissipate any heat generated and repeat. Do this ten times. It should take about 10 minutes and maybe 5 miles if you don't have too many other cars up your chuff trying to get past."
