Hi, first post here. Got a van I'm looking to pick up for work (2012 E250 4.6)...they have a video of it on YouTube
Has a slow knocking and high rev it seems. From doing a autocheck last time there was any recording was a bit over a year ago so I'm assuming the gas is bad. Anyone have an idea what that knocking may be? Rods?
Too much ambient noise. Hard to tell. Towards the end (0:51) it seems that he rev it up and the clicking remains at the same frequency. I had a catalytic converted with the inside destroyed and made a similar sound, but it would change with rpm.
Good luck with the purchase neighbor (The Woodlands here)
