I have a 2001 Toyota Highlander with a leak somewhere in a lower engine seal. I got a quote of between $1200-$1600 to repair it. Is using a “Stop Leak” oil treatment product a good idea just to keep squeaking by. The vehicle runs just fine otherwise and I just want to avoid coughing up the money for a large repair like that if possible. Thanks in advance for any advice.
Please do not use stop leak products, It will only further damage your engine. If the car is otherwise in good condition it’s probably just best to fix the seal that is bad, and any other seals/parts that would need attention while they’re already in there and have it taken apart.
