ERR7146 - Timing Cover

I usually only use Britpart for the most innocuous of parts, however the price of their timing covers (ERR7146) is attractive – I could buy two and still pay less than a genuine one, and have some change! I’d like to seek thoughts about this specific part, rather than Britpart in general. It does have a bearing, which makes me wish to proceed with caution. I really CBA to replace the bearing alone as I’ve got enough jobs on my plate!
