I wont take the plenum off and try to start it then
RE the oil: I asked for 10/40 oil but have a feeling it was 30 cant lay my hands on the receipt but remember seeing it. Didnt think it would be a problem at the time
will an oil change to 10/40 cure it?
blue smoke was definitely coming out the exhaust. Was thinking of taking as much apart as I can at the front today and at least cleaning it and having a look but realistically if smoke is out the exhaust is there any way it could get out the sensor or through the plenum and be pushed back into the engine and through the exhaust?
I am hoping its curable as I love the car but in my heart of hearts I think its not viable to repair if it internal seals as I am not that confident on engines
