I'll stick details up once it's underway. It's not beyond the skill of a competent DIYer. My issue is I only have a small front drive to work on (the car just fits, and then it's the pavement!) I also have to clear everything away at the end of the day so would be almost impossible at home.
By the time I'd hired an garage space for a few days, and an engine hoist, and then transported all my tools there and back, I'd probably be several hundred quid into it before I'd even turned a spanner, sp no option but to pay to have it done.
