I have a 2001 Super Crew, 105 K, 2 wd, Triton V8. When I start it when the temp is cold the oil pressure gauge goes from normal (sitting 1/2 way between H and L) to zero and the red oil light comes on. Within seconds it goes back to normal. It does this several times, and then as it warms up it stops. There doesn't seem to be any change in the motor when this happens.
I am worried I have a serious oil pump problem, any ideas ?

Thanks,
joe

 

the oil pressure gauge doesnt actually measure anything. the sender or sender contact is fubar.

 

I have the same truck and have had it for three years and after the first year it it started doing it. so dont worry about it. i know a guy that has a dodge and it does the same thing when it is cold. so you are ok
