Hahaha I enjoy doing the odd tinkering, until i get into the difficult stuff, and the really messy stuff....
What I said earlier about British cars, just changing the oil filter and oil in the Disco is a messy process... Pull the filter off not problems, and not that hard to get to, residual oil then bounces of two different parts of the steering system, making it hard to catch, then there is the sump which when emptying lands straight onto the anti roll bar and agin splashes oil everywhere! So unless you have a can of degreaser laying around, and clean everything as you go, you end up covered in oil!!
An of course being a land rover, it doesn't have an oil leak, it just marks it's territory
