Why wont motor turn after replacing timing chain and guides

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?

On a 2001 Ford Expedition how to get the crankshaft to turn freely to put in time

I know the answer. The hub rubs against the cover. The original timing sprocket is larger. The cloyes kit on eBay much ???

We replace the timeing but we where trying to check the Timing mark but won't turn all the way round go half way then stop

Hi im just curious if you ever resolved the issue. Im experiencing the exact same thing you just described. Any help would be awesome
