Hi Mike.
All we know from your posts so far is:
1)You've checked the engine oil level with the engine running which tells
us exactly nothing about your engine oil level.
Did you top the oil up?
If so, when did you last check it (mileage), and how much has it used
since (in mileage terms).
What is the level when the the engine is not running. Preferably at least
10mins after it's stopped. Why not park it up on level ground, go and
have a cup of coffee, and then check it.
2)You have a blowing back box.
Replace it.
3)You are frequently stalling.
