Well, today was the day to start up the new 207 engine,warm it up and get it hot and set the cam...then I stopped it to check oil level first..noticed milky looking oil on dipstick..bad news..water is leaking into the engine somewhere!! Big Setback, drained all the creamy oil.. we'll pressure test radiator ( GMC rad,was was sent to me by a friend)..it was checked also. Rebuild guy won;t want to hear this news...Engine block and head was Dyna fashed...what could cause this? We will turn engine today with starter, remove the plugs to see if water spurts out of any...any other suggestions?.about ready to give up! mtvoices...
