RTV Sealant
When I sealed up the bottom off the engine with Permatex ultra black I do not waited an hour before apply torque. I forgot to do this step and I'm not sure if I'm going to have oil leakage problems in the future.
Has the same thing happened to someone and had a leak problems? |
I mean, pulling the engine to do an oil pan is such a fun job, why not risk it?

I mean its a great way to spend the afternoon in the shade in/around/under the car

I use Toyota FIPG and don’t wait any time before torquing. Granted laying a bead, installing the gaskets, baffle, pick up tube, another bead, laying the pan on top of all this, and finally torquing is probably a ~20 minute ordeal. But I never have leaks.

Thank you very much for the reply 👏😅

I used the same RTV and I torqued it right away, no leaks. Waiting an hour sounds weird. When you torque something that has been RTV'ed the sealant flows to conform the materal and make a good seal, it then sets up. That is the only way I have ever read to use RTV.

You're correct, but there's also (usually, not sure for every brand but the Wurth stuff I used to use did) a specified time you're supposed to let it skin before putting parts together. Usually it's: Apply bead, leave for X minutes, then join parts and torque. Basically, you let it part cure so it's still sticky and pliable, but not totally set. Join too early and when you torque the pieces up it may just ooze out the sides and leave a tiny amount of RTV that wont seal well. Join too late and it's too firm to conform to crap surfaces and will leak. TLDR: read the label. |
I use Permatex "The Right Stuff" 1 minute gasket maker and I never wait. It does set really fast though.

I use grey silicone and it skins for about 20 minutes while I do all the stuff Curly mentioned above. Not only it never leaks, separating the pan from the block gets pretty difficult if you ever have to remove the pan for whatever reason. |
