/forums/images/graemlins/angryfire.gifWell I just finished starting my new rebuilt engine for the first time. Guess What? It is eating the coolant and burning it out the exhaust /forums/images/graemlins/angryfire.gif!!!! This is the exact reason I rebuilt it to BEGIN with /forums/images/graemlins/angryfire.gif! A little background for everyone. 1 jimmy gets hot - got new thermostat 2 worked good for 2 days then radiator sprung a leak 3 bought new radiator 4 worked fine for approx 2 weeks then started getting hot again 5. again changed thermotat 6 engine ate up all coolant 5 or 6 times got hot! 7. figured had a bad headgasket so decided to rebuild 130k 8. sent everything to a "very good " machine shop 9 .030 over, heads reworked, block heads blasted and baked 10. everything checked good 11 rebuilt 12. started it ran fine for approx 5 minutes then ATE the coOLANT again. 13. $1000 dollars and still at sqaure 1 WTF????? /forums/images/graemlins/angryfire.gif Anyone have any ideas warped head? Cracked head? It eats the coolant in a matter of 1-2 minutes so it would have to be a major crack or leak somewhere and should have been easily seen at the machine shop right? Please help I am losing patience fast with this thing!!!!
