Any advice much appreciated.

Owner said engine revved by itself, then white smoke from then on. From start up, slight misfire (comes and goes), consent white smoke from exhaust.

Round 1:

Oil level found to be excessively high (owner has admitted to "topping" it up with oil) drained out oil, then drove it to burn off oil from exhaust, on test drive missfire got worse and smoke stayed.

Round 2:

Compression test all between 300-350 psi.


Round 3:

Fault code relating to No.2 cylinder, swapped the injector with No3 and the fault code followed injector and low reading from bleed off test. New injector, smoke still remains. (Simons ECM, give injector vales in %, new injector gives 100% reading and the other 3 between 60% and 120%).

Round 4:

Smoke/random misfire, still remains, defiantly smells on fuel, now on Auto Talk for advice! Please! Many thanks.
