Ok I checked my oil today and it was real low again

I check it fairly regularly. Anyway today the temp sensor was riding a little higher than normal and I noticed an oil patch on the floor after I pulled away.
Oil leak is somewhere from the left hand side looking at the engine from the front. Any ideas before I go crawling under her ?
I topped up with oil and the engine was roasting, drove her home tonight and again the temp gauge was rising by the time I was nearly home, was at nearly half.. think If I put an egg on the rocker cover it would be cooked in milliseconds lol.
Any ideas welcome, cant get underneath her till weekend
Cheers
Dan
