Oil Sump Leak Sealant - What Works Best?

What if you accidentally overapply and it starts to ooze out? Panic mode or is there a quick fix? Asking for a friend… haha!

I’ve had a lot of trouble with oil sump sealants over the years. I found that some of the cheaper brands just don’t hold up. Anyone else experienced recurring leaks?

Yes! I used one sealant that started leaking again after just a month. It was so frustrating! What brands have you tried that actually worked?

I had similar issues with the sealant I used. It seemed to degrade quickly. Has anyone found a sealant that stands the test of time?

Great question! I’ve heard good things about the Permatex Ultra Black sealant. Has anyone here used it? Does it really last longer?

I’ve tried Permatex before, and while it worked decently, it didn’t completely eliminate my issues. I’m curious, though, what prep work did you all do before applying the sealants?

I always clean the mating surfaces thoroughly before applying any sealant. It’s crucial! If not done right, the sealant won’t adhere properly. What are your thoughts on that?

You make a good point, khawkins. But did you ever accidentally leave a bit of oil on the surface? I’ve done that before and it ruined everything.

Oof, I can relate! The last time I tried to fix a leak, I ended up making it worse and splashing sealant everywhere. Sometimes it feels like DIY is too much work.

I think some sealants can be too forgiving. I’ve used one that set really fast, but I had no room for error. Anyone think that’s a plus or a minus?

It’s a double-edged sword, really. Quick-set is great if you’re confident, but a disaster if you’re not. I definitely appreciate a bit of work time!
