04 CRF 100 Oil Pump Problem?

[martinact420]

Hello all. So I redid the top end on an 04 crf 100. Before the rebuild the bike blew oil out of the clutch arm. Right after the rebuild, the bike blew up again. I noticed the engine getting incredibly hot but my buddy told me thats normal. I dont know if it is or not but the bike did blow again I think. It;s making a grinding noise when the kickstart turned over. I havent taken the bike apart yet but I did notice that it did not blow any oil through the clutch arm. Would this be a bad oil pump. The bike had full oil and was ridden for about 10 minutes after the rebuild prior to going down again. Please let me know what you guys think. Thanks.

sounds like an oil passage block that is building pressure in the bottom end and relieving through the loosest orifice(lololol), the cluch arm. Use any sealants on this engine?
