Well the new oil drain plug with a larger diameter sealing face,a brass washer and Permatex high temp sealer is leaking Amsoil. I road it over the weekend and didn't seem to have a problem.Today I did a 100 mile ride and it's leaking,I'm very disappointed. | ||

If you installed timesert it can leak between the timesert and the case, not between the plug and the timesert. Also it might leak on the brass washer. Do not use brass washers, those are good only for high torque steel on steel applications, not for low torque steel on aluminum interface. (Message edited by TPEHAK on November 03, 2020) | ||

This is the thread sealant I use: https://www.pepboys.com/permatex-high-temperature- thread-sealant/product/9560871 Never had a plug leak. | ||

Mike, whenever you drill the hole for the timesert you have to also spotface the area around the hole with an endmill or counterbore so this area is 90 degrees to the hole. When it pulls tight it can't have any angle and it must be flat. Drilling by hand and achieving that is really hard. That's why I recommended that you countersink the timesert and use an o-ring to seal it. An o-ring can make up for any irregularities. You really need to drill and spotface in a milling machine to get a flat washer to seal properly. | ||

Tom,that's the sealer I used. Greg,the Timesert is a 1/2",would you suggest I get a 1/2" or 3/4" diameter 82 degree countersink? | ||

If you meant it's a 1/2" OD and your drain plug is a smaller diameter then I'd get a 1/2" countersink. This way you can cut into the timesert and leave a shoulder that will capture the outside of the o-ring. Not too deep though, just a little support is fine. Consider it more of a funnel to force it inwards. Did you use a sealant on the outside diameter of the timesert? Tpehak is right about it leaking around the timesert if there's no sealant. | ||

The outside diameter of the plug is 1/2",I was thinking that a 3/4 countersink would be needed for a 1/2" OD.I didn't use any sealant on the outside of the timesert. The instructions didn't recommend sealant and what discussion I read about timesert installation,I don't recall anyone mentioning sealant on the outside of the timesert.I guess I should install a new timesert with sealant.The FAQ page says that an insert can be removed with a spiral point screw extractor. http://www.timesert.com/html/oilpan.pdf | ||

You might try the c'sink first with a new o-ring. If it works great, if not then you can try something else. | ||

I've never removed a timesert so I'm thinking out loud here. But, I'd be concerned of damaging the already fragile swing arm metal. I would give loctite_290 a try before removing the time sert. https://www.henkel-adhesives.com/us/en/product/thr eadlockers/loctite_290.html | ||

Tom,this would prevent me from using the 290, "Requires heat for disassembly". I have a countersink and some o-rings ordered to try Greg's suggestion first. | ||

Countersink should work long as the oil is not seeping past the OD threads of the time-sert. |
