The Gold Seal myth
I am always on the lookout for 200Tdi engines: they are getting much harder to find than they were a few years ago, and even rough ones usually yield some useful bits. One thing I keep noticing is adverts for 'Gold Seal' 200Tdi engines. Gold Seal was the brand name used by British Leyland and later Unipart to promote its factory rebuilt engines, available through the BL dealership network to fit to your MGB GT or Morris Marina 1300. They were expensive but had a good reputation. Sadly, your 200Tdi is not a Gold Seal engine. The Gold Seal brand was phased out long before the 200Tdi first appeared. Land Rover was never part of the Gold Seal network and all 200Tdi engines were painted pale gold from new. The colour tends to darken with age. Sorry to break it to you.
