Q: How much to replace rear main seal or will BlueDevil rear main sealer work?

asked by on January 03, 2017

My Tundra has a bit of oil leaking, and I had a yourmechanic mechanic (great guy: last name Bradshaw) come out to inspect it today. He said that the drip is slow but would only get worse. So my question is how much would I expect to pay to get the rear main seal replaced? Or, do you have experience using BlueDevil Rear Main Sealer additive; would it be worth using? BlueDevil claims their sealer does not attack the seals like other additives do but restores the seal to original; is there any credence to this? Or will it destroy all my engine seals? I'd like to know from a professional's perspective.

Thank you!
