Just got engine put back in truck engine was rebuild and cleanedo the works. Got engine in put all new fluids etc in got it running and let it run for half hour or so. When to change oil to get the breaking metal shavings out. When draining oil realized it was really water and even had slight green tint. So I'm getting coolant in my oil somewhere. Everything in and on engine in new from pistons to gaskets to thermostat. Any ideas? I'm thinking lower manifold gasket maybe not set right. Really don't think it is head gaskets being new and in properly

 

Are you sure you got everything torqued down to spec?

 

Positive rechecked by my father in law when putting it together

 

Probably is the intake gaskets, you have to be careful installing the intake, and sequence torque down.

Just a thought, does it have the "heated" PCV. If that is the case, and it's bad, you can suck coolant that way? Or a heater hose hooked to the PCV valve.........just kidding.

Good luck

 

I'm gonna check manifold gaskets tomorrow hopefully that's it and the heater hoses are hooked up right but no clue how'd that make it go into our oil?
