Ok so i have replaced clutch master cyl. Only to find I need to renew slave. Haynes manual says remove exhaust from manifold. I can hardly see it Never mind remove. IS IT REALLY necessary to remove just to let the engine tilt a bit to get box off ? Can I do this job on my tarmac driveway , with 2 big trolley jacks and an engine crane that would be pushed in from the side. And several axle stands , any advice very welcome. From someone who has actualy done this in there driveway.
