danieldu Posted June 22, 2007 Report Posted June 22, 2007 Hello, I am still rather new to bansheehq and I thank everyone in advance for your help. I have slight pitting on the surface of my crankcase where the cylinders and the case meet. I was wondering if I should have it resurfaced or if it would seal with a good sealant? I had my case powdercoated and the shop neglected to cover up the surfaces when they sandblasted the case(error). Either way it is too late and I need to figure out the next step. Thanks, Quote
swrbansheeboy Posted June 22, 2007 Report Posted June 22, 2007 from what i see you should be fine just slapping the gaskets on and torquing it home but if your realy worried you can put a light bead of yamabond on there between your case and base gasket. either way once it's all together do a leak down to make sure there are no leaks from your base gaskets...

Thank you that is what I was thinking, but it is always nice to hear a second opinion. Quote
letsgetthisdone Posted June 22, 2007 Report Posted June 22, 2007 i'd throw some yamabond or high temp RTV on there just make sure. Nothings worse then blowing it up an hour after you get it runnin cuz of an airleak that could've been prevented. Or tearing it back down when it doesn't pass the leak down test... Quote
David Keith Posted June 23, 2007 Report Posted June 23, 2007 Yamabond will seal better for a longer period of time. Go ahead & try it. If it leaks, then it may need to be re-machined. Quote
RZBansheeMan Posted June 23, 2007 Report Posted June 23, 2007 I wouldn't be against mixing up some high temp epoxy and filling them in carefully and then using a flat edge to carefully scrape it flush while it is still pliable. Quote
BigRed350x Posted June 23, 2007 Report Posted June 23, 2007 I wouldn't be against mixing up some high temp epoxy and filling them in carefully and then using a flat edge to carefully scrape it flush while it is still pliable. I just finished doing some epoxy work on my cases and that's probably what I would try. Easy way to check it after whatever you choose to do... bolt up your cylinders and get them torqued down, while you are doing your heat cycles spray some carb cleaner around each of the gasket surfaces of your top end. If there's an air leak it will suck the carb cleaner in and you will hear your engine bog real bad. Quote
danieldu Posted June 24, 2007 Author Report Posted June 24, 2007 Thanks for the replies. Any suggestions as to what kind of epoxy I should use? Quote
