this maybe a dumb question to many but how do you clean your upper timing chain tensioner besides replacing it, also a vid would be nice if anyone knows of one

Do you know how to remove it?
Pull the valve cover off
Pull the upper timing cover off
There are two 10mm bolts holding the tensioner to the head, remove them
Take the tensioner and push the metal rod (piston) in and it should push back out. There should be resistance against you while you push it in. Keep pushing it in and out like 50 times. Now soak it in parts cleaner for a couple hours and then clean it off. If it pushes in and out smoothly, you are good to go. Bolt it back on your head and get that car running again.

old bump but related question; i have a tensioner that was very hard to compress (i.e. we stood on it repeatedly to get it to compress all the way). i'm guessing that even if it were full of oil, it should not be that hard to compress?
i've already ordered a new one, but my thoughts on this one are that the inner oil passage hole is somehow blocked? the outer one we can get a pin though and know it's not blocked?
now that the oil has seeped out of everywhere else it can, the tensioner feels like it should, but that's just the spring tension. i have a feeling that there will be no oil pressure in the tensioner but have no way of knowing if it's blocked or not as I can't take the tensioner apart and check
