I am getting a tapping sound when I start cold. Goes away in about 3 seconds when the oil pressure goes on. I read a tech tip from the benzbin.com that states, "If you start your engine, after it sits all night, and you hear clatter which quickly subsides when you get oil pressure you probably are on borrowed time. Change the timing chain tensioner pronto regardless of how many miles on the engine."

Yes I understand it is a ratcheting type tensioner. I will install the new one set to the first detent. However, what I was wondering was how difficult will it be to push in the tensioner cap given the new spring?
