Hello. Thanks for any help at all. First off I have a 730 that I am the second owner of. The tractor has been sitting for 5 years from bad wiring harness. I rebuilt that and got it going again. Changed oil and coolent. After driving it down to my barn I was almost there and it started smoking white and gotten hot. Smelled like coolent. So I pulled the head. Couldn't tell where it was blown on the gasket so I put new gaskets on and everything back together and went to start it up to warm it up to tq the head and thin I noticed it had no oil pressure at all. Now I am lost. Any help will be appreciated!
