hey guys,i have a 51 f3 flathead that was just rebuit from the ground up.started it up,smoked for about 20 seconds then stopped.ran good even test drove in the driveway,parked back in garage and saw coolant leaking out of the passenger tailpipe(i rigged two small exhaust tubes one for each side as temporary exhaust) so i performed a compression test,all cylinders were120 psi so im pretty sure i dont have a gasket issue,the block was sleeved and pressure checked by a reputable machine shop any ideas?im thinking cracked head on left side ,i did use sealer on the bolts and they were retorqued twice.any ideas?
