Ok Guys,

My buddy is lookin for a new engine for his 96 teg. His mechanic found him one with 150 psi across the board for the comp test, and oil 40 hot ......I told him that the comp test looks ok since it is across the board and everything, thgoh I could be wrong I'm still kinda new to this, but I had no idea what "oil 40 hot" meant......does anyone know what is meant by this?
