I never once had no problems with my redtop throughout ownership, yeah fair dues I fully rebuilt it before it was fitted to my corsa but I never once had a problem, kept it well maintained, warmed up first thing, was one of the best engines, same for the C20LET I had, full strip and rebuild, always looked after, not one problem. Its dickheads who buy them and don't look after them who give them a bad image for reliability. I'd always be tempted to go back to one again, but maybe in an astra gsi this time, too much power for the corsa. Damien
