OK, I put it in the freezer for a while and went to put it in. I got it most of the way in, not sure how much farther it needs to go. The timing chain sprocket goes right on. At first I tapped it in with a plastic mallet then once it was in, I went to the heavy artillery, a dead blow hammer. I whacked it a bunch of times and it ain't going much of anywhere.
Here's the timing sprocket. Does it need to go further on to the crank? There is a step in the crank snout which prevents it from going further back.
The one on the top is an old OE one and the bottom one is the MP one I am using.
