Indeed just keep an eye on the cats and water/oil pumps.
If they are going to let go it’s the bottom end that I’ve seen fail on the Ferrari derivatives...usually ending up with a conrod poking out the side of the crankcase.
Are you sure you're not thinking of two of my Dad's Austin Maxi's and his Austin Princess?
Seen the con-rod poking out of the side all those three engine blocks. My Dad, God Rest his Soul, seemed to think oil was a luxury, despite being a mechanic in the REME during his National Service.
Funny about Dad's and cars. He'd also leave it until the last minute to put petrol in, 'There's another 20 miles left, easy' - splutter, splutter, of we go for a walk to the nearest petrol station. We once ran out of petrol in the middle of a scary right turn into a major thoroughfare. So consequently I've never ran out petrol, never missed an oil change, never had an engine let go on me. Thanks Dad!
He also told me Spaghetti was actually made from worms (can't eat Spaghetti) and the long central reservation gardens around the back of Bolton Town Hall are Giant's Graves (can't walk on them).
