Well bugger me silly all my probs with the car at this stage have been due to a blocked pcv valve and all the breather hoses to old and collapsed so deleted the pcv and set up a catch can.Did this yesterday has stopped going through all the oil,missing has stopped at idle along with the smoke.

So fingers crossed it's all good I only checked because a friend of mine with a 1jz chaser had similar probs and told me to check out the pcv valve.
