I know on my recent timing chain replacement, we also replaced the top chain sprocket (gear). The teeth were pretty pointed and non-uniform. This may not be necessary in your case, and you won't know until you get inside.
That's the benefit of having someone like Steve perform the work.
1. The deficiency was detected
2. The part was ordered and installed the next day
3. It only added ~$65 to the job because the tech was aready in there working.
4. Came with a full warranty.
For me it was $$ well spent to not have to worry the sprocket was going to accelerate wear on my new chain and/or lessen my driving enjoyment.
Steve ?? is this a common replacement item, or do you find the teeth are rarely to the point (ha ha) of needing replacement?
