So my son and I have been very slowly working on his Ranger. The weather and life just hasn't made it easy to get to. Anyway, we finally buttoned it up today and it's not running. We did the timing chain components (we were already there, so why not) and the camshaft synchronizer and valve cover gaskets. So, after the truck wouldn't start, I was doing some digging. I think we installed the top timing cam upside down.
The only video I could find on the webs doing a timing chain replacement on a 4.0 OHV had, with cylinder 1 at TDC, the bottom crank key at 12oclock. The top cam had the dot also at 12 o'clock. (see video screenshot). This is what we followed.
But, and I can't find this but in one place - (on charm dot li) - I found a picture that shows, with cylinder 1 at TDC, the bottom crank key at 12 o'clock and the top cam with the dot at 6 o'clock! Please don't tell me we followed the only video we could find on this and it was wrong. (see screenshot of drawing)
Please help - do the dots point both at 12 or bottom at 12 and top at 6.
