Hello everyone, first post here. This forum has helped me tremendously over the past few weeks as I've gone through the process of swapping the motor on my 02 4.0 SOHC and I'm hoping the members here can point me in the right direction with my newest issue.
To give a little background on the issue:
My XLT has 230k on it and the timing chain on the front bank gave out completely without any warning (took out the piston and intake valves on cylinder 4 in the process). After much debate with my wife, we decided to pick up a new motor and do a swap since we have a Jasper trans with only 60k on it and we both love the truck. I ended up finding an engine on craigslist advertised with 112k on it and new chains for only $650.
I pulled the valve covers after getting the engine home to verify the chains were new and to do a quick glance over of the internals. The rear chain was brand new and the front chain looked as though it had been replaced within a few thousand miles. The crankshaft keyway was facing 12 o'clock and the stub on the driver's side camshaft was straight up and down. I don't remember with 100% certainty the position of the stub on the passenger side bank, however I want to say that it was up as well (again, not certain).
I went ahead and did the swap after watching a lot of cruzroy's videos that were posted here on the forums and the new engine is now in the truck. Unfortunately, it does not want to turn over.
I double checked the firing order, verified both spark and fuel pressure, and checked with my scan tool but found no DTC's.
Is it possible that timing is off due to that passenger side cam? If so, am I able to just unbolt the cam gear and spin the camshaft 180 degrees?
If the timing is correct, are there any other ideas as to what it could be that's causing this? I just want my Explorer back! LOL.
