Questions & Answers

A picture of the acdelco 89060436 seal in the advertisement indicates that it comes in a 4-pack. Do you believe this to be true?

The seal is the only one. Even after using a tool to align the installation, the one I used leaked. Installation may be easier if you do it the normal way rather than reverse, as the factory and everyone else did at first. Face it in from the outside. I watched it done, and there were no leaks. It's a good engine but the rear main seal setup is bad, especially with a big turbo and wider ring end gap.

Selected User Reviews For GM Genuine Parts 89060436 Crankshaft Rear Main Seal

It is not uncommon for them to leak even after being installed with special tools

3/5

The seals on the GM automobiles have a tendency to leak oil since they were flipped backwards. In particular, if you are using turbo applications, this is a bad deal. My jaw dropped when I heard that these rings aren't equipped with a more effective seal for the bigger gap at the end of the ring. I've had to pay hundreds of dollars in repair costs due to these seals.
