Jeff210R Posted October 6, 2021 Share Posted October 6, 2021 I've just refitted my sump today and I wonder what people's views are on the curing time for the sealant?The Loctite 5980 Technical Data Sheet says 21 days for full strength which seems a bit excessive!JeffLoctite 5980 Tech Data Sheet_2.pdf Link to comment Share on other sites More sharing options...
aerobod - near CYYC Posted October 6, 2021 Share Posted October 6, 2021 One standard technique for silicone RTV gaskets is to apply the gasket bead and torque the bolts evenly to a jointing torque value that is about 25% of the final value, leave overnight, then torque to the final value the next day. The gasket will continue to cure to maximum strength for a longer period, but should be fluid resistant and ready for use after the second torquing.

Jeff210R Posted October 6, 2021 Author Share Posted October 6, 2021 Too late now as they're all torqued up to 20nm! I'll probably leave it a couple of days and test for leaks unless anyone has any strong advice to the contrary? Link to comment Share on other sites More sharing options...
John Vine Posted October 9, 2021 Share Posted October 9, 2021 The film thickness will be tiny, so I think you could fill with oil and go the same day. That was certainly the case with the Ford sealant (1217470) that Raceline supplied with my Duratec wet sump, and Raceline made no mention of curing times. The key is to make sure sealant has extruded all the way round the join.The Loctite 5980 curing data says:According to that, even a 1mm film cures in a day, and your film will be much thinner.JV Link to comment Share on other sites More sharing options...
