low oil pressure

  1. Naturally Aspirated
    I replaced the lim and uim gaskets and valve cover gaskets on my 04 Monte Carlo with the 3800, ran good lastnight. Today low oil pressure light came on when the car warmed up. Any ideas of anything I could have messed up or broke?
  2. Bottom End
    I'm in a pickle. This 3800 has been true blue all 124k miles. I had a lifter knock when the weather was really cold. Now Ive got a knock, which goes away when I'm accellerating. The Mechanic is trying to sell me a Jasper Motor or a GM replacement. Another place wants to rebuild it for 2500.00...
