Wish I had that problem.
But you have any luck. It should just thread in, no leverage should be needed.

Haha, I did mine because of an exhaust leak too. Figured it was easier, and I was being lazy And figured if it wasnt the tick, it wasnt going to hurt anything.

I see that CED has a timing chain tensioner bolt listed. Is that required?
Also, I assume all you guys bought the ACDelco part, iinstead of off-brand Cloyes(?), right?

FYI - when rethreading the new tensioner, make sure you press on it with a CONSIDERABLE amount of force while simultaneously turning the bolthead. Otherwise the threads won't catch.

I didn't need much force at all to get it threaded in, and it torqued down without a problem

I pulled my new one apart since I read I was supposed to set something. But didn't see anything. So I compressed it and re-installed the retaining clip.

Should it be good to go or is there something I have to do because I took the plunger out???

The way it sits the tensioner tip is spring loaded and takes a fair effort to press in still.

Im beyond paranoid to do this since this is my daily driver.

you're not supposed to take it apart, you just take the old one out and put the new one in and start the car and it sets itself. You guys are making this way too big of a deal

I still hear a rattle under slight acceleration and when accelerating from a stop. I'm guessing its something different?

Its no big deal when youve done it lol.

Im more concerned about **** popping apart into my motor, timing skipping and the vast amount of different opinions about how to do this.

Some say just screw it in.....some say lock it then release it once its screwed in. I cant afford a mistake with my daily.

In 5 years, this thread will be 10 pages long... and people will still be asking if they can just screw it in and start the car... or do they need to set it.
