Message: [QUOTE="TARM, post: 1423627, member: 578"] But then it should not be ok once its started even cold. Sure as it warms up that changes things but if I am understanding correctly its only starting it the initial time and only in the cold. Would an issue with the injector cups create an issue? If its losing oil and its not from a leak at the normal external places I tend to question injectors hpop. How does the valley look? It is dry. See if you can trace out the path down the rear if you have a leaking hpop. Have you put a scanner on it while cranking? Would like to see what kind of ICP etc.. I have always wondered about hydrolock damage on a engine that does not fire up at all but is only cranked by the starter. The force can only be that of what the starter can apply and then the lever affect of the flywheel radius. Hell most of our old starters seem to barely have enough tq to get these 7.3 turning over in the cold. Compare to say the force of the cyl pressure @ say 1000ftlb I guess I could stop being lazy and work the math. Say its a 200 ftlb for starter at the gear. flywheel is what 12-13" diameter so half that or for easy math 1/2 foot. SO we work it just like adding an crows foot or similar to a tq wrench. half a foot would increase it 50% so 300 ftlb tq. Compare that to force the CP inside the cylinder puts on the rod and crank at peak TQ. Not sure I can see that bending a rod. Now if a cylinders were firing and it locked up that would make a mess. I could also be way off here in my calculations. But I can not see how a starter with a maximum stall tq of 200ftlb even with the leverage from the flywheel length(so 300ftlb) could bend a rod on a engine capable of putting more than that at the flywheel in stock config. Someone that knows please correct me if I am way off. Above is more a question looking for confirmation than anything. [/QUOTE]
