Updated crank seal
Hello eveeryone I am a new member to the forum so I have a number of questions that you regulars have probably answered a hundred times . I have a 1098 race motor in a 1960 Huffaker BMC Fjr .I have all the info on the car back to 1960 so there is a wealth of information.The motor that is now in the car was built in 93 and was dynoed at 98 hp.I ran it last year 3 times at track days and it runs superb but leaks oil like a sieve thru the rear oil seal.After 2 or 3 sessions the oil gets on the clutch and I get clutch slip.I have pulled the motor and box and intend to fix all the leaks.This required taking the center bulkhead out and completely stripping the car.I changed the front gearbox seal and now I want to fix the crank seal,Mini Mania has the updated crank seal that runs on the crank flange and I have heard conflicting remarks on whether this is a good idea, or should I just replace the standard type seal.I also have rubber seals TAM1089 on the sump pan which I understand are early morris minor .Are these better than the cork seals ? These rubber seals are hard to find. Since I will have the motor apart I will change bearings ,oil pump ,clutch ,water pump etc.The bore looks fine. Thanks for any input.
