Hey!

I got a problem with my E55 AMG and the problem is very irritating...

My engine (wath i think) have some strange shaking some times, the shakes will only come if i have it in P or N, never in D or R. The shakes is not very big but you feel it and like i sad it is very irritating..

I have changed the spark plugs, check the car at a computer (No fault messages or something)

I hope someone can help me and maybe some other E55 owners that have the same problem like me.

Bad motor mounts

Yeh bad motor mounts. Got both mine and trans mount from partsgeek.com 185$ shipped.

did you replace the spark plug wires along with the spark plugs? These cars aren't the smoothest when idling. A slight miss/ vibration feeling is normal. However these vibrations may be emphasized when you have bad motor mounts.

Motor mounts or possible the spark plug boots weren't fully seated on each spark plug?

Mine shakes on cheap gas. By cheap I do not mean 87 octane. I always use premium. If i stop at 7/11 my car shakes.

MACH-E55

Id say mounts and I dont think you sould be running nothing but 93+ on forced induced cars

Energiiz

Thanks a lot, i will first check the sparkplugs ans the wires. If thata OK i will order mounts. The fuel here in Sweden is from 95 to 99+ so thats good!

pimpjuice

you can see if its the motor mounts because they will look wet. they are fluid mounts and fail a lot. Mine idles smooooooooooth...but my mounts went bad and they are a PITA to replace!

Not much of a choice here in NorCal, it's been that way since August 1st, 2001. 91 octane for us suckers on the left coast.

I have now checkd the sparkplugs and the wires and it looked great. I talked with a mechanic and ask how to check the mounts i did like he sad but they looked fine. Another thing that i saw when the engine was running is that the pulley didnt go "straight" it was like that the stock was destroyed.

Can the pulley maybe be the cause?

A wobble in the pulley sure it could cause vibration in my opinion.

My car had a bad pulley and I changed it and it did help the shake a little but the mounts were also bad. Put the car in drive, step on the brake and give it gas, if the motor lifts up a lot then the mounts are bad. One is probably bad but you will do both while you are there. My experience tells me that your pulley and mounts are bad. Book gives you like 6-6.5 hours to replace but my guy is fast and did them both in under 4 hours and it was his first time. Again, he is pretty fast. The pulley is pretty easy. It's the pulley to the left of the motor, I think it is the idler pulley? Good luck.

Energiiz

The mounts is good. Checkd it today. The pulley that i mean is the crankshaft pulley .

Energiiz

Thats the pulley i talked about, that one is wobbeling.

The question is where can i by this one and how mutch will it cost? I called the MB dealer in Sweden and they wanted about 900$...

The part number is A1130300103

gaspam

hopefully that pulley is not wobbling a lot because that is your crank pulley with harmonic balancer.... looks to be stock pulley

60nomad

If that is the case then just get and aftermarket smaller pulley, not sure I have heard of that pulley going bad but what the heck do I know? Others with more knowledge will chime in I'm sure.

Great info.. I just found out that my drivers exhaust manifold has a stress crack.. best price for part only is about $375 at genuine merc parts. Chardul suggested having it pulled and welded and put back on. Also, mentioned that engine mounts can cause this as excessive vibrations stress the manifold mounts sooo...just want to be sure regarding parts...

Went to partsgeek as suggested above found these:

http://www.partsgeek.com/catalog/200...ans_mount.html

http://www.partsgeek.com/catalog/200...ine_mount.html

the tranny mount I heard of course, to just do it at the same time. and those engine mounts had two type billstein and corteco. does it matter billstein is good name and cheapest...

or stick with genuine oem for these?


and if anyone knows a btter price on genuine merc drivers exhaust manifold please let me know.

thanks much

Ps. Getting labor prices now

novae500

I have febi bilstein motor mounts that I purchased from parts geek and didn't need since my mounts are still good. Also have ds exhaust manifold w 55k miles on them. Will throw it in if you buy the engine mounts plus pay shipping

cobra101

Ok, mechanic lifted up....motor mounts are good. We saw the old stains where the originals failed. Replacements look like it was done with the last couple years...

I thought bout buying used manifold but knowing the same spot fails on these, I am probably going to have it pulled and welded. They guarentee the weld, they say and its a little more than half the cost if New one. I fig the manifold is good except the typical spot that stresses. Looks like it did not go all the way around and weld will work. The rest if manifold typically does not fail from what I read...


Think it will work.

Ps. I may do left lower control arm at the same time. Bushing seems bad, as told by two mechanics. bout 400 installed. Car had a very light play bushings/front.

cobra101

Update: Weld on exhaust manifold held and was quiet. For about a week

Now shop claims they can not see any cracking around weld and that the noise I am hearing is not an exhaust leak and pretty normal. They say can't fix something, they can't find a problem with. inspected weld and no "Apparent" cracks.

Of course I know it did not make this sound when I picked it up from weld. Now same noise is back under same conditions.

Is there an upgraded exhaust manifold? Just buy one from genuine merc parts and have it installed for piece of mind? (hopefully not for full labor again).

I also noticed that bottom crank pulley? shown in picture in this thread, is also wobbling a bit? Should I worry or just keep driving it normal and enjoy?

thanks

Ps. If anyones manifold cracks, I would certainly just buy new one to elimiateit from the equation, not to mention for peace of mind alone.

might as well just get yourself some evosport shortly headers

Many luck with your issue? Dealer told me sometimes after changing Trans/motor mounts Exhaust manifolds Can cause a vibration at a stop when in gear. Suggested to Loosen manifold bolts so exhaust manifold can relax and retighten manifold bolts.
Any ideas if I should try this before replacing Trans mount again, btw transfer case weight mount was loose and fell off but didn't see any damage to Trans mount. Assuming transfer case mount was loose all along.( before and after the motor/ Trans mounts where done about 3 months ago.
Thanks so much

W211_350WagoN

I had same issue with weight falling off, put back on and now a vibration at stops when in gear. Did you loosen manifolds and if so did this work? I replaced Mounts/ Trans mount replace less the 20k ago. Thanks in advance!!
