I have a rear main seal leak. Can I use blue devil sealant. Does it work? Can it damage anything? Repair will cost 1800 dollars

  1. I have not tried any of these products personally. If the product is and does as it states on there website, I don’t see any harm in giving it a try. Less than $20 vs. $1800….
