Nothing. Sorry, but if you were talking about a leaky gasket, there are additives that will swell gaskets and subsequently stop leaks. In your case, major work is unavoidable.





You *might* have limited success with JB Weld. If you can get to the crack that is. Clean off the area very good of all oil and dirt - a brake cleaner works good for this. Mix the JB weld and apply it liberally to the crack. Let it sit for 24 hours - no exceptions. This might slow or stop the leak long enough to get by.





However, I'm assuming your block cracked from something breaking inside the engine (rod?). I can't imagine it's still running or will run for long if this is the case but a tube of JB Weld is less than $10 and worth the shot I guess.





Good luck.What can i buy to stop oil leak incar ? engine block has crack cant afford major work ?
I know of a couple of different substances that seal cracks in engine blocks and cylinder heads. Permantex makes an excellent sealer for casting leaks. I would recommend jbweld sealer for your engine block. I hope for your sake that it isn't a very big hole and that it doesn't leak too much oil or coolant. Good luck.
theres ways to fix things but no body knows what you are talking about.
