Asked by Sep 21, 2012 at 05:29 PM about the 2001 Ford Expedition XLT

Question type: Maintenance & Repair

The original timing guides were damaged, so I removed them and replaced with new chain, sprockets, and tensionors well after replacing went to started and motor would not turn so I removed them and tried to spin crankshaft still would not spin, I removed the pan to inspect shaft, rod and bearing everything is in order. It is not frozen because it will turn about an inch back and forth nothing else was removed it has me baffled. Any ideas?

It sounds to me like you didn't set the timing correctly. Did you line up the marks on the timing chain with the cam and crankshaft marks? You probably have a piston hitting a valve and since it didn't get a good spin, you probably saved the engine. Re check your timing! Did you check the manual to see how to set it up to begin with? In the future, use your digital camera to document where everything belongs as you take it apart. This will help a lot when you go to put it back together.

I know this is an older post.....however i just had a similar issue. except i dont have it all put back together yet. I tried rotating crank after replacing guides. And the left one will not hardly budge,,,, Backing up just a bit i was stupid because i wasnt TDC to replace guide at the start....when removing tensioners the left cam spun. So i had to rotate everything independently.....Is it possible for the left cam to be one entire revolution off?
