Hi Guys! I have a 455 4 speed 70 GTO. When I purchased the car, it had an oil leak. The rear main rope seal was leaking, so I had it replaced with another rope seal. After several hundred miles, the leak reappeared. I then had the rope seal replaced with a 2 piece viton seal. Again the leak reappeared after several hundred miles. Can someone please offer me advice on what I can do to stop this continueing problem?Also, is it recommended polishing the searations off the crank shaft when using a non rope seal?Thanks in advance,jkell
hello butler performance sells bop one piece seal. it has one cut i it instead of two and have been said to work. the searations are ok.
Thanks shyrgfuh3 for your response. I appreciate it.jkell
I just used a one piece seal from Butler about 6 weeks ago, it hasn't leaked a drop since. I left the sarations on the crank with no problems.
