I just did this today, I had hardly any oil spill out, until I tipped over the tensioner and removed the piston. When I installed the S54 tensioner I didn't notice it needing tension to get the threads started, but maybe I just have big muscles

My tensioner was the same, as pointed out already in this thread, its normal. Just thought I would re-post that.
