What do you suggest for a stop leak product for a leaking rear main seal?

I don’t. These products rarely work very well and I’d be concerned the variable valve timing in your engine will be negatively affected.

If the seal is leaking a little, ignore it but check your oil frequently. If it is leaking a lot, get it fixed properly by replacing it.

When the front main seal started leaking oil on my Honda five months ago, I added this each time oil needed to be added.

Each time I added it instead of oil, the slower the leak got, until it stopped.

Tester, are you using it at 20% of oil capacity?

There’s a 1/2 quart of the Lucas stop leak left in the bottle used in a 4.5 quart oil capacity system.
