197 Engine removal, clean and replace

Recently bought a 197, It has got a oil leak coming from the timing cover housing?
I am planning on removing the engine to fix this along with cleaning the engine and bay then refitting.
I could do with a bit of advice or pictures from people that are familiar with this and anything that I should replace while I'm at it etc, cheers

Planning on removing the engine on my 197. Wondering what the procedure is? If anyone has any pictures? And will I require any special tools... Cheers
