I am reading that, and it sounds like, I have to jack the engine up slightly to get the oil pan out. Theres a leak down there which I can only assume is the oil pan becuase I don't see any other obvious leaks.

If I have to get at it, what is the method specifically of getting the engine into a postition where I could do the job? Thanks

the ideal situation would be to put it on a lift and use a rotating jack on the harmonic balancer to lift it up

The reality of it being you probably dont have access to a lift, so just put the car on ramps and use a good jack on the harmonic balancer it should give you enough room to do it

Good luck
