Main bearing replacement overview
My oil pressure
dropped, so I
replaced oil pump
and and all new
gasket . & New rear
main seal replaced
.new timing belt &
chain . No oil leaks . I
added 1 qrt. Of lucus
oil & 5 qrts. Of
10w30 . But after
truck warms up the
pressure drops to
about 6 lbs of
pressure is that
normal ? When
engine is running at
3000rpm oil
pressure is about 25-
30 pressure. Is that
normal ?
