Is there a way to check timing chain with tearing engine apart?

Trying to figure out options.
After seeing the piston pictures, do you think there could be damage to the connecting rods?
Do the pistons need to be replaced?
I read that if the dented area of the piston doesn't hit the cylinder wall, that it would be OK.
I'm thinking I'll pull the head, and weight the cost of buying a remanufactured head, or having mine worked on.
What other engines are compatible with this car, with a 6 spd. manual? I know it won't be a plug and play, but something that won't require moving engine mounts, etc...

I would not attempt to fit another type of Benz engine. To many expensive issues to address.

Thanks for keeping up with this.
I'll get started on the head, and post up here what I find. Might be a couple days or so, depending on work.

Matt - if you ever hear a minor rattle of the chain against the chain case on cold startup that shuts up the minute the oil pressure comes up it's time to consider having a new chain pulled through long before the chain gets loose enough to jump. You need to listen with the drivers door open. You can seldom hear it with the doors closed until it's too late.

No - you can just pull a new chain through as per WIS instruction I posted earlier in this thread.

I don't have any noise, I was just asking what exactly to look for. If it shuts up as soon as oil pressure comes up it must be very brief. I just don't know what exactly to listen for. Wish someone had a recording of the noise. Anyway, my car doesn't seem to make any strange noises during start for now. I just like to be informed and on top of things.

Good!
EDIT. It's such a cheap job to pull a new chain & fit a new tensioner compared with fixing the mess caused by a jumped chain.

I had a decent recording of it. But I just updated my iPhone and it restored back to December. So I lost everything in between. Don't update over wifi. Plug into iTunes.
I was getting rough starts when it was cold, like it was missing. Then it would smooth out after about 10 seconds. And the rattles, that would last just a second or two.

Chain rattle comes from the chaincase between the crank & head. It is not constant or you would be in big trouble.

Hi Glyn, I was checking on mine today, and there is some metallic sound but seems like it's coming from exhaust manifold.
How long in time does it rattle before the oil level comes up? Mine seemed to do on for 10 seconds before I turned it off.
Also, I opened the oil cap with the engine running - to listen - and air was blowing from there (not too hard, as I was able to put the cap back on with no effort).
Is it normal, or my gasket is worn @ 118k mi?

VVF - it is normal to have blowby from the oil filler cap. This is a captive breathing engine.

Can you make a video? I don't think ticking is indicative of the chain. I've been trying to understand the noise, too, but if you think about a stretched chain rattle.. you can almost imagine it. Plus it would be brief, the oil pressure comes up quick.

Matt - just imagine a brief Grrrrrrrrrt of a chain slapping against an aluminium housing. Aluminium actally amplifies this sort of noise whereas steel does not.

Here's where I left off last night. Hoping to have the head off today.
Anyone know the unbolting sequence for the cam cage thing(sorry, not exactly sure what to call it), and the head unbolting sequence?
Got some great info from mikey1011 on the other post. Along with some of the DIY's.
Glyn, I'm going to replace the balancing chain, would you suggest also replacing the guides for the balancing chain?

I recall that FIAT put grooves on it's 1500cc engine pistons used in such cars as the X19 (which I owned) so that JUST IN CASE the belt snapped, the valves would not impact the pistons. This after it happened many times in the earlier 1300cc.
You were supposed to replace it every 30K miles. I did mine religiously, once I learned how to do it.
Of course, Mercedes would never want to admit such a thing could happen, and therefore of course would never bother to build something like that in. something a lowly company like FIAT used way back in the 1970's.
Sorry to see your troubles.
You seem to be on the right track!
You didn't purchase the service DVD?

PM Johnand or splinter & ask them to post the R&R. I don't have torque specs, order of undoing/torquing etc. You really need that.
