2004 dodge dakota 4.7 V8 228,000 miles
I just bought this truck for $500 as a project to play around with.
It was sitting for 2 years never started or driven because it needed work. Needs tires, brakes, and ball joints that I have no problem doing myself.
CEL is on but it is just emissions related (evap)
However, I am stumped on what I believe is an oil issue.
Every time I start it after it sits for more than a few minutes it sounds like its starving for oil.
If I turn it off and start it right back up it wont do it.
It only lasts for a couple seconds but it sounds like I’m dragging an anchor on the pavement.
The sound is much worse than the sound you get when you change the oil.
It has an oil pressure gauge that registers pressure as soon as it starts (about 20 psi) then it slowly climbs to 40 psi after about 5 seconds
The first thing I did before I started it was put in a new battery, checked the oil that was in it and it was on the full mark, checked all other fluids, and put in some fresh gas. After sitting that long it started right up. Idles nice a smooth and quietly. No valve tap or knocking or smoking.
I changed the oil and filter as soon as a got it home thinking the valve in the filter was bad or the oil might be sludged but that made no difference at all.
I was told that synthetic oil was always used. (I bought this truck off the original owner)
But he said that regular oil was put in by mistake at his last oil change over 2 years ago before it was parked.
I changed it right back to synthetic 10w-30 Not sure if that makes a difference but I wanted to put in all info possible
What do you think is wrong?
