Hello,
The 235 engine of my 1952 Chevy 3100 leaks oil at the rear main bearing seal. One shop said, that it is necessary to remove the crankshaft and change the front and rear seal. There is no other way to do this if I want a good deal. The other shop said, it is just necessary to remove the rear mean bearing cap, change the lower seal and for the upper seal they have a special tool to change this seal. The first shop will need 16 hours, will remove the engine from the car, remove crankshaft and so on and take for this job $ 1800.-. The second shop says, they will need just 3 hours, will take $ 200,- for the job.
What shall I do ? Is it necessary to remove the crankshaft to change the seal ? Or is there a special tool which allows to change the upper seal without remove the crankshaft ?
Thanks for your help.
Tom
