I have the enginebuilder kit in my 22R, and had a DOA Racing chain kit. The DOA Racing chain kit lost the tensioner after about 5000 miles and the long guide went kaput. I don't know how in the heck it didn't jump time, but it did slap like crazy under 1500 rpm's.
I ended up putting in a Carquest chain kit and now it's good again. Like was stated above, it's really best to pull the oil pan just to make sure that there's nothing in there and it's not like it takes another 3 minutes to pull it. Also as stated above, after you pull the disty, there is a bolt in the pool of oil beneath where the gear was. Lots of people have not found this bolt and ended up busting there cover due to prying it off.
It's overall an easy job, and one that most anyone with common knowledge of engine work can do.
