LiftdT4R Posted May 22, 2008 Report Share Posted May 22, 2008 Hey, what's up? I havent been around in a long time, but I noticed the other day I have oil leaking out of my drain plug. The plug seems reasonably tight, and it had a brand new copper crush washer on it when I put it in. I was using 40 weight PJA oil though, and I think that may be too light, anyone else ever have this happen, if its just the oil I would gladly switch back to the 80 weight gear saver. Thanks!!!!

okbeast Posted May 22, 2008 Report Share Posted May 22, 2008 I don't think changing oils would stop that leak, or any for that matter. Are you 100% sure it's coming from there, b/c that's the bottom-most part it could be leaking somewhere else and running down to that.

LiftdT4R Posted May 22, 2008 Author Report Share Posted May 22, 2008 Yeah, I'm 100% sure, I took off the skid and I can see it seep out by the gasket, and then drop. When I removed the bolt, the drain looks fine, no beinds or cracks, and like I said, the gasket was new, so I'm kind of at a loss. Quote Link to comment Share on other sites More sharing options...
glassjawjm Posted May 22, 2008 Report Share Posted May 22, 2008 (edited) Is it an aftermarket Drain plug?? maybe some debris carved up the crush washer on its way in. crush washers are pretty much one time use, but i think in this application you could get away with pulling it off once or twice, unless its wrecked by debris, have you pulled it off and cleaned it up?

locogato11283 Posted May 22, 2008 Report Share Posted May 22, 2008 you should be able to put water in there and it not leak. switching weights isnt gonna be a fix. i dont even use a copper washer. i put a little yamabond or gasket maker on the threads of my drain bolt and ive never had an issue. ive been running 10w-40 motor oil in my tranny forever.

LiftdT4R Posted May 23, 2008 Author Report Share Posted May 23, 2008 Damn, I took a look at her today in the light, and there appears to be a hair line crack on the top of the drain, running down the side. Must have been from when I last had the motor out. I just rebuilt this entire motor, and I really don't want to take the entire thing apart to replace the bottom case. Any suggestions? Maybe some JB weld? I can grab a pic if needed. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted May 23, 2008 Report Share Posted May 23, 2008 so the crack is in the lower case? Quote Link to comment Share on other sites More sharing options...
LiftdT4R Posted May 23, 2008 Author Report Share Posted May 23, 2008 so the crack is in the lower case? Yeah, it starts at the bottom of the drain at the threads and goes to the top of the drain, it's basically a hairline crack I think it happened when I was shuffling te engine around while it was out of my bike. I'm thinking even a little high temp RTV might do the trick, but I wanted to see if anyone else had any other solutions. As always thanks :beer: Quote Link to comment Share on other sites More sharing options...
250psd Posted May 24, 2008 Report Share Posted May 24, 2008 Gouge it out a bit and JB weld it to you are ready to replace. Easy on the drain plug or you'll make it worse. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted May 24, 2008 Report Share Posted May 24, 2008 yea i think i would try to run a dremel along the crack and then jb weld it. i think thatll bond better than just trying to use some sealant. Quote Link to comment Share on other sites More sharing options...
