I watched it last night. I was curious. Does the TR4 engine use thrust washers like the TR6? If so, they never even checked them, nor did they take the head off. I guess the compression was good and the car was not smoking. Ant did install an "improved" water pump with 6 impeller vanes and a two-piece rear main seal plus an alternator and of course reversed some wires. They paid $6,800.00 for the car, put in about another $6,500.00 and sold it for $16,500.00. They got a new doorskin from England custom made. $1,340.00 as I recall. Car was clean and rust-free.
