So before I get to the point of serious dismantling, can anyone advise what engine checks would be worth doing whilst it's still all connected up and able to run? I was told that a fair amount of engine work was done on the car (65 TR4a) in the States about 10 years ago (but only about 8K miles ago) but I haven't been able to find out exactly what was done (or why). The engine seems to run pretty well, oil pressure comes up quickly, idles fairly smoothly, no obvious noises, exhaust a little smoky on initial choke but seems to be ok after a while. I did detect a little oil when putting my hand to the exhaust, but only a little. Usual oil leaks under the car, haven't pinned down exactly where from yet. So what checks and tests would be worth doing at this stage to inform later decisions on engine work? Compression I would guess would be a good start?
Any thoughts gratefully received
