Can small cracks inside the crankcase be treated with Silicone RTV gasket cement?
I have separated the crankcase of my Honda CD200 Roadmaster. There are numerous minute cracks inside the crankcase. I dont think welding is necessary because the cracks are due to wearing from thousand miles of bad road. Can i cure the cracks using silicone RTV gasket makers? I have one on my shelf called Hardex. Would that be ok? cause the silicone stuff doesnt melt even on high temperatures.. Thank you.
Sorry forgot to mention i have no oil leaks absolutely. and the cracks are like short streaks and less than 0.4mm depth. they are present around the crankshaft housing and the kickstart housing. the bike is atleast 25 years old. but still in very good shape. cheers
Are you sure your not just seeing casting marks? Does oil seep out at these locations? I would recommend against using and RTV sealant or JB weld inside the crankcase all it would take is a small amount to break loose and it could destroy the engine.
