Oil pressure
I have a tapping noice on my 07 chevy
avalanche (and a misfire code 307 on the
same cilinder, not sure if related...)
I changed all the spark plugs and wires,
troubleshooter the coil sensor (good),
opened the head cover and flushed the
lifters and push rods with carburetor
cleaner and lubricated again. The push rod
on cilinder 7 is loose but not Brocken.
Put back together and drove; check engine
is home and truck rum smooth but tapping
noice still there, but got a message of "low
oil pressure, turn off engine!" Why is
that???
I'm planning to flush the oil tomorrow and
change oil filter. Any ideas?? I changed the
oil pressure sensor about 2 years ago
