Tech Question
michael hamilton, mount vernon, IL, 05 dodge dakota 4.7
I have 05 dodge Dakota 4.7l .the first thing I had was tachwas inop at times and oil light will flicker when hot . I took it to thedealer and had them replaced the cluster before I diagnosed the oil pressureproblem. I got vehicle back now the tach works but the oil light flickerswhen hot and with gauge hooked up and sending unit together. The lightstarts flicking at 9 psi at idle.
Any ideas?
Mike-
Truthfully, 9PSI hot at idle isn’t all that terrible, as long as it comesright up the moment RPM is increased. Worried anyway? If you have confirmedthe oil pressure with a mechanical gauge, there’s a few things you can do(assuming the oil pump is OK)…
1. Try a heavier oil
2. Change the main and conrod bearing
3. If really high mileage, either a compete rebuild, or swap to abetter-condition junkyard engine.
