So my Crankshalf pully bolt flew off few months ago, bought a new bolt and wooduff key, had it fitted and it lasted for couple of months before the old pully, being a bit worn at where the key bites, got chewed off and i had to buy a new Pully.

Had the new pully fitted, it went fine for few more months until one day i noticed the spacer washer was a bit loose, so I re-tighten the bolt again with load of Locktight. Now after couple days of driving the 19J started to puff white smoke heavily, and running hot even at idelling!

I've cheack, there's no oil in water or water in oil. Could that be sign of cracked pistons? Failed Turbo? Or crankshalf's on it's way ?

Any Ideas ?
