Re: 97 Volvo 5.7 GS Water in Oil
You mean the oil pressure on the oil in your pan? Or the oil/water mixture pressure on the oil/water mixture in your pan? Whatever that gauge is reading is pressure on a bunch of crap water/oil goo. Your Only running it on a hose I'm guessing, once in the water your that engine won't last long. Especially if its in salt water. JB weld might stop that EXTERNAL water leak you have, but it will do nothing for the impossible to fix internal water leak you have.
If you do attempt to drive it, I would buy a towing membership. Because you won't make it back from the first trip most likely. Start shopping around for another engine.
