    So the new Febi part is a little different than a new OEM one?

    With the M62 motors being 8 cylinders, is there 2 tensioners needed or only 1?

    Replaced mine yesterday. The old tensioner on the left was stuck in and there was no play with the spring. I soaked the new one in one before I installed it. Less rattle on the first startup after the install and on the startup this morning the rattle was completely gone.

    Ordered a tensioner today. I've read a few threads that said the new tensioner is compressed for ease of installation. Can anyone who has recently done this confirm that this is true?

    +1

    Update: just did it and no issues whatsoever. I didnt need the wobble piece. I just used a deep 19mm socket tool, 8" extension and 3/8" ratchet. Oh and a rag for the oil that leaks out

    I have a question and its probably off topic and in the wrong place but i need help. And I cant find what I need in a search.. my car is a 97 540i v8 146k miles. has been great no ticks knocks or rattles of any sort. well this morning it sounds like the timing set just fell apart randomly and its now constant still running perfect though. No im not driving it and only let it run long enough to hear the problem. My question is is this going to be a definite guide failure or could this be a tensioner??
    Thanks in advance!

    The only true way to tell is to drop the oil pan and look for plastic chunks.

    Do you have a bore scope? You can snake that in through the oil fill cap. It's usually the middle "U" shaped guide but sometimes the passenger's side can break.

    I can get my hands on a scope, However if it came down to it.. Would it be worth my time to take the valve covers off and get a closer look from the top? Or is the best bet from the pan/underside. Thanks!

    The pan lets you see the bottom of the U and will obviously contain any pieces or residue from wear. I recommend it. I did it to my old 540i. It's very simple and just costs you a gasket and an oil change.

    I want to take a minute and say "thanks for this thread". I have an 02' 540i with 104,000 miles and the ticking noise at start up had become progressively louder. I ordered a tensioner and installed it in about 15 minutes. They do come preloaded, I fiddled with mine and it became "un-loaded"...lol. It would have been much easier had I not coon fingered with it. Once installed, I started it up and it worked perfectly.

    I fixed my tensioner problem and it works great. no more ticking noise and running smooth. it just cost me $3 for a new spring instead of $80.

    here is the thread of how i did it my self:

    I found a spring that supposed to be the spring for the timing chain tensioner, is this right, http://www.eactuning.com/ssf/part_nu...01%20706%20809 they want 4 bucks.. Is it supposed to replace the tensioner's spring?
    New link for this, I can't find just the spring replacement vs the entire thing for $60 on eBay.

    This is NOT the spring for the tensioner and only listed as an updated link to a previous post. It is for a control valve near the oil pump in some I6 engines.

    The spring in the picture isn't the same as the ones shown throughout the thread. Am I missing something?

    I like the idea of doing this to keep tension on the chain as my 98 740iL motor ate itself alive once the timing chain guide came loose (poor rework by a company that head replaced the headgasket prior to my purchasing the car), but at the same time I worry if this renewed pressure is a good thing since there are stories of tensioners breaking into pieces. It's stopping people from having rattle, but at the expense or increasing pressure on an already worn out chain guide.

    High spring tensions aren't the death of the rails. It's the smacking of the rails when the engine starts and dies that causes failure. I'd rather have a tight chain than a loose ones, especially with aged rails.

    Bought and received the spring, have yet to do the work. As I stated though, the spring in the pics and what I received are two different looking items. Doing a Google search using the part number provided, it lists I6 engines, not the M62TU. Once again, am I missing something?

    Ordered this based off your link, for the third reply now...it's different! Please give me the correct part number. VIN ending in LH13219.

    Based on the spring in the picture, it can only go one way as the smaller end sits on a little nipple while the larger end just sits inside the assembly itself. Reverse it compared to the image below, that was taken just for the sake of comparison that EAS gave me the wrong part #.

    James,

    I'll look up the spring and see what it fits.

    It should be noted that someone asked for a new link to a part number mentioned earlier. I have no idea what they were using the part number for, nor am I suggesting it fits anything in particular. That's why I quoted that member's post.

    I'll edit the post to reference that the link is just for the previous request.

    It was I that asked for a new link to the replacement spring via your website. I bought what was in the link, and while the picture in the link is correct and what I received, I had no idea the size differences of the spring in pics vs having it in hand. I included in my post the size difference, which is nearly 2x larger than the current spring in my tensioner. Per the part number in the link you provided, every search I come up w/ says that spring is for an I6 engine, so even if there was some random miscommunication, an I6 spring shouldn't have been linked in an M62-specific thread in the first place.

    In the meantime, I've stretched my stock spring back out, fought it like hell to get it to go back in, but ultimately I'd like to get the correct spring replacement.
