Harley Twin Cam, deep dive into the cam chest! pt 1 of 4.

Join me while i keep this early 88" twincam with 83K miles on the road. this reliable engine started to make some noises at low idle, so we are diving into the cam chest. Compresstion/leaked down test (see other videos on mt channel for that) and oil pressure test came back ok, what could it be, the lifters? By part 4 shes all back together.
