How long rtv to dry

The RTV allows the gasket to extrude out between the mating surfaces in some cases. My favorite was seeing a cork gasket on a valve cover hanging out all over with big gobs of RTV all over the place. I've seen it more than a couple times. Having worked on the heeps I say that with love as long as I did, I can sympathize with people who find engineering faults. I had to also repair many of the things the factory didn't do right. But for the most part they get it right. As for when RTV should be used.

In any case the best bond seal is attained when the RTV is allowed to set up for some period of time, check the product you are using. On valve covers, I would normally allow it to setup for 15 min.

Generally, let it set until it just starts to lose its tack. Then be careful to set the piece in place without disturbing the bead.

That brings up my last point. RTV's great attribute is the ability to fill imperfections in the mating surface ever seen the mating surface on your t-case halves, very rough machined surface.

I hope this helps. Eastern Raider , Dec 11, Next time pick up the "The Right stuff" rtv sealer from permatex you can use it and 5 min later fill up.

Vehicle: 3 Grabbers. Dave B , Dec 11, Our RTV at Chrysler is formulated for trans pans and fluids. Bolt the pan on and fill it up. Never had one leak. The fluid wont penetrate the bead created in the pan so it doesnt effect the seal between the pan and case. Used it for 20 years on valve covers and trans pans. Our differential rtv is a redish orange color designed for diff fluids. You need the right rtv for the right job.

If in doubt go grab a tube from the dealer. The dealer wont use a product that takes long dry times nor would the factory supply us with such product. The last time I took it to chrysler, they used black.

Yeah,things dont sit in shops for a day before getting filled and started. Ive always done it within the hour. Usually as long as it took to get things back together and get done. Jan 17, 7.
