This happened this week on a mf13. Hydro locking is a bad thing

Water/coolant doesnt compress. When u introduce that into the engine the steel has more give than the water therefore the rod bends over the water giving more

No this happened cause a cooler blew and coolant hydro locked the engine. Deleteing it keeps this from happening. It also jubked the block too. Needs a whole new engine

ive seen this more then i can count on cummins engines the great thing about the ISB is the egr cooler is above the engine and it runs back into the exhuast and into the cylinders and then you got to start it and she is locked up. ive seen a ISX do the same thing as that maxforce but it didnt ruin the block not trying to brag but i guess them cummins blocks are stronger then them Internationals ha ha

I don't think the coolant will run back in the cylinders with the velocity of gas exiting the exhaust ports. More likely what is happening is that when EGR is commanded it pulls through the cooler, exhaust gas and coolant, into the intake side, and then you get the big bang. :thumbsup:

The rod.bent so bad that it smashed.into the side of the block. When the engines shut off I agree as on the mf13 its above the engine. Itlk run back into the clys as will the isx even though its behind the turbo
