Well they are testing the oil pressure right now. It came on for a second this morning so I turned it off and restarted it, and it was gone hopefully a good sign. And that was -20 C but it gets alot colder than that up here.

 

Alls good. Oil pressure to spec. Changed the oil sender,13 bucks and changed bearing in an idler pulley. No more engine light comin on at start up. Thanks for the info. Much appreciated
