I have been a reader here for a while but never a poster.
I bought an 04 Durango about a year ago with 87,000 miles at the time.
It now has 107,00 roughly.It is a Hemi 5.7.
My wife was driving today and out of the blue started making a knocking noise so she pulled over.
After I had it towed to work it had a horrible engine knock.
I checked oil and it was at proper level as was coolant with no overheating.
After running it for a minute the noise went away but a bad misfire was present.
I checked the manifold pressure with a vacuum gage and found only 5 kg/cm instead of 20 atmospheric pressure.
Obviously internal engine damage like dropped valve maybe.
I am about to fork over $1800.00 for a used engine but am wondering if anyone has had this happen?
I am an auto mechanic for Honda and have maintained it to a tee.
My wife said no driveability problem or noises until this happened.
I guess I don't really have a question other than what the heck?
That and maybe if anyone else has had this happen.
