My dad blew his most recent MG engine because of what that might be, the pressure sending unit had some sludge or grit in it, or something that would never allow it to be an open or closed circuit (how ever it was designed) so it read 30psi at idle and would creep up at higher rpms so it wasn't completely jammed which made it quite deceiving, though it was never noticed that it would shoot to 30psi from just turning the key; even after the conrod tried getting out of the block. You might best try another sending unit, just test it.

[that wasn't the last engine, the most recent spun a rod bearing in september]
