New BOP One-Piece Rear Main Seal
New Product:
Viton® One-Piece Rear Main Seal The new BOP Engineering one-piece rear mail seal is the most advanced rear main seal on the market for the traditional Pontiac V-8. This revolutionary design features a number of state of the art innovations including relocation of the parting line which greatly reducing the risk of leakage. The seal is simply sliced at a premarked location and slipped around the crankshaft. A more pliable construction works more effectively in engines with seal groove geometry issues, and double lip design to provide twice the protection against leakage as well as supporting outstanding vacuum numbers. Recent testing pulled 22 inches of vacuum when silicone from around the valley pan failed. Visit our website for complete installation instructions. O RMS18 3.00-inch Main One-Piece Rear Main Seal $49.99 O RMS19 3.25-inch Main One-Piece Rear Main Seal $49.99 (coming soon)

I'm a rope guy but I might try it. I would like to take a look at the install instructions. Could they be posted? Or a link.

So you have to cut it to install it?
If so, why is it not sold precut? |

Wade...that is some down-home Wisconsin ingenuity! Nice work. If have to pull my motor for a rear main issue (mine only leaks a small drop), I will put one in and give it a try.

Wade, might be a good idea to make a you tube video to show the construction and an installation of the seal.

My rope rear main seal is also dry but this may be worth a try in the future.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
