06 cr250 coolant leak

Recommended Posts

Eh guys. 

Just did a full engine rebuild and I've done one heat cycle. 

Im leaking coolant from the Allen screw bolts above my exhaust outlet.  I've replaced the o rings that are on the inside of that exhaust/power valve piece. 

Im wondering if I either didn't seal it right with the gasket maker, or if those Allen head screws aren't done right? 

I had the cylinder replated. And it came back disassembled. I didn't do anything special to assemble those screws, just some blue thread locker. 


Thanks for the help.

Perhaps one of the orings got dislodged during assembly? Obviously it has to come apart. What did you use as a gasket maker? I'd take it apart, try to identify where the coolant is coming from and reassemble carefully. A thin bead of black RTV would probably be my option if everything looks correct. And not sure you needed blue loctite on those bolts...did the manual call for it?
