Instead, why not try sealing that leak from the outside? It might sound like magic, but you could be back on the road with a leak-free engine with the right products and a little elbow grease. So buckle up, folks, and learn about sealing motor oil leaks from the outside.

Can You Seal An Oil Leak From The Outside?

It is possible to seal an oil leak from the outside. There are various products available on the market that claim to seal motor oil leaks from the outside, such as sealants, stop-leak additives, and gasket repair kits.
