I getting ready to move, so I don't have time to work on my car. I am taking the car to a friend for him to do some work on it. I was going to have him pull the lower oil pan and look for plastic from the timing chain guides.
Have any of you guys been doing that? It seems like this might be something good to do.
why?

b/c of threads like this

I will be replacing the chains and tensioners and guides soon as I figure what tools are required to do the job. My car is a 99 and has some sort of knock from the front of the engine as well.
It looks to be a pretty expensive job, even for the DIY. To replace all the guides, tenioners, and chains, I think I got a parts total of like $650. Thats not counting any gaskets or special tools.
BMW chains usually last the life of the car

Wouldn't you only need to replace the rails guides, since it is the plastic guides that deteriorate?
Looking for an E39 belly pan , passenger front inner fender liner …
Can we organize some sort of kit to be able to purchase as a whole that includes the needed gaskets and rails?
Or can someone just post up links to each item, I would do it but I just got in the e39 world and I don't know the websites very well yet.
The chains are cheap. The tensioners and guides total $500.
Yes, but the life of the car can be defined by how long the tensioners last.
I had the job done in December 07. We replaced everything that we could find in there to replace, because we didn't want to go in there again. Big job -- I was charged 10 hours of labour, IIRC. Valve covers, oil pan, timing covers all have to come off. My chain jumped a tooth as well. We were lucky that it didn't jump more.

Wowzerz.
Just looked at that thread. Pretty crazy, but both motors look like they had a strict dino poop diet - one fed good fresh dino poop and the other looks like it never saw an oil change.
EXTREME neglect:

This IS scarey stuff. Thanks for brining it up, again, OP.
I think fresh synthetic and a new tensioner (#19 in the diagram and easily swapped-out) should go a long way towards adding some longevity.
Garrett
that's probably only if you don't hear anything already?
if removing the tensioner, do you have any chance of giving the chain too much slack and jumping a tooth?
$650 for the chain parts? Wow, that's cheap (google M88 timing chain parts)!
Timing components will last a very long time as long as everything is well maintained. The M88 problem is that the tensioner gets sloppy, causing rattle and slap, and the guides will disintegrate (especially if they're 25 years old). I'm not surprised the M62 has a similar problem.

I can count the number of M62s that I've done that job on with both my hands.

According to a indy around here, my startup knock/rattle/whatever is coming form worn guides or something along those lines. It was relayed to me by nc540 and did not seem to be an expensive or overly difficult job to take on. I'll get more information soon because I need to do something. Embarassing startups will only be that way for so long if my chain decides to shit the bed. Then I'll have to drop an LS1 in there.
I asked my indy about this a couple of weeks ago after hearing another member's car cranked up after sitting in my garage for a couple of days. It made quite a racket... My indy said he's replaced lots of chain tensioners on cars 99 and newer, and seen failures on those cars that weren't serviced, but said mine (and older) aren't really candidates for failure. I hope he's right.
M62s or M62TUs? Every failure mentioned so far has been an M62TU (thankfully).
Ah ha! M62s look like they use a metal timing chain guide

I'm getting scared.
Is there any way to properly check for tensioners and guides wear and chain play before something really awful happens apart from removing the front of the engine? "Listen if it rattles" doesn't seem too accurate..
