pressure test your engine, that'll let ya know the condition of your seals ... it should hold 6lbs for 6 minutes

Same thing happened to me last year. Right hand seal went out. Mine didn't overheat, though. Yes, you do have to split cases

ok here is what i found my drive gear on the end of the crank came loose and the nut shot through the case lost the w/p gear seal case cover and w/p bearing sucks total rebuild i guess first time for me any help to stop this from happening again

87 before u start tearin it apart try just flushing all the coolant out that might be part of ur cooling prob and ur gonna need to reseal the cases thats why its leaking oil out the bottom their sealed form the factory but over the years it wears out of course, i had Jeff at FAST do it for me

 

And i would richen up that premix i wouldnt trust that 50:1

[banshee87]

can i seal it wit yamabond you are talking about the bolts that go through the case out the bottom right

[batoutofshell]

if your case is cracked or broken in that area you have to replace it
