4.4 4.8 Timing Chain Guide - Page 4

I went to have nine installed and the shop told me the A/C compressor has to come off on my 02 4.4. They said they managed to get a wrench on it but it was stuck on. They said a two day job.

I'm going to wait until I change the water pump in the spring and I will have them take everything off the front of the engine and do it then. I don't want to work on the cars anymore or I would do it.

Funny story, I went to open the box at the shop...on the box it said handle with care. These are put together a certain way that the plunger stays in. Well I dropped it and the plunger dropped out and it went in pieces. The picture is after I dropped it and you notice it's longer than the box and wont fit back in. They returned that and I have a new one ready to go. I use an independent shop and he used to work for BMW. He buys aftermarket German parts that BMW uses.

Please post if you were able to do it without taking the A/C compressor off.

Did it come with a new O-ring seal?

No it didn't.....guess I should order one.

I read the dealer and independent shops don't want to do the job once the chains go and look for used engines. I've also read posts of 4k to do the job.

If you search YouTube your bound to find someone who did this on another car like a 7 series with the sane engine.

The gasket for the tensioner is the same exact part as the drain plug washer. I have 4

I posted a link to a video.

I watched this 540 video. No compressor movement. I just looked at my X. Looks like the compressor is not in the way.

Is there a DIY for replacing the timing chain guides? I know it's a helluva job since the entire front of the engines needs to be removed...lol!

Interesting thread, seems like a great preventative.

My car is at the dealer to get the defective door handles replaced. I asked for an estimate to replace the lower timing chain tensioner and they said $225...I said go ahead. I guess you can get to this buy just removing the air cleaner and it's located above the a/c compressor.

They had one in stock and were familiar with it like they replace them all the time. I have to find out more of how often they replace them.
