New Member and W126 owner.

Post by Mercal560 » Fri 16 Feb, 2018 8:55 pm

Hello all. Thought I'd properly introduce myself. My name is Callan and i am currently the owner of two W126s

I have long wanted one as my father has had one since around 1997. So early in 2017 i bought my first W126

I started off with my 1983 560SEL. I know what your saying. I didnt make sense when i looked at it. I imagine this car has an extremely interesting story. But it has a euro spec engine and it surprisingly quick. The numbers dont match and the car is rough. But i love it. We call it the Whale.

Upon realising i had bought a lot of work i decided I needed another one. Adding to my eight car collection.
I bought an immaculate 420SEL. Its a 1987 model in Diamond blue. The interior and paint work are immaculate and the body is rust free. Unfortunately the day i picked it up the previous owner had run it almost out of fuel and now its running like a complete pig.

It is a tad low in the front. Still rides and handles well. But I do worry about the front end a bit

So it appears the 420 isn't as sideways as the 560....
This is the day i bought it in need of a detail.

So i am budgeting a timing chain, guides and tensioner on the silver 560. On cold mornings I have heard slight rattle on start up on colder mornings.

The 420SEL needs a few more things. Originally i thought the exhaust was blocked. When it had no power and appeared to be getting hot. The exhaust was due for replacement so it is gone

And it still runs poorly and has no power. Now i am leaning towards blocked fuel filter and pump. As i earlier stated the day i picked it up it had almost no fuel left and began running poorly.

I ran out of fuel in my old 560SEC and had the same symptoms after. New fuel filter and was back to normal.

Welcome to the forum Callan.

Cars looks to be in great condition.

You're doing the right thing by changing timing chain. If you don't know when it was changed last, get it changed.

I would check the basics, plugs leads, distributor, rotor button, filters, etc....

Welcome - car looks really nice. I guess the 560 has been fitted to a 500 if it is 1983. I wouldn't even start it until you do the guides etc. If the guide breaks and goes between chain and cam wheel as they often do and it happens in a heartbeat - motor pretty much becomes a boat anchor or very expensive bill.

I would say if he let the tank run almost dry it picked up crud in the tank bottom that has got past the tank strainer and into the twin fuel pumps.
If the pumps whine sounds more noisy than normal/ or noise tends to cycle up in pitch - then you have a pump issue
Also the main fuel filter might also be clogged up and there is a fine mesh filter in the fuel line-in where it screws into the fuel distributor that you could check out whilst fault finding.
Seeming it has only happened since he let the tank run very low it sounds like a fuel delivery related issue to me

Thanks a lot. Yeah prevention better than a cure really. I am slowly going through the 420s standard stuff. I have noted it has cheap leads i will bin.

basically what i am hoping. I have ordered filters and hopefully that's a good start. I was worried it was the fuel distributor itself but when dads 380s FD packed up it could rev and not seemed starved just rough.This seems starved.

Welcome. Nice to see another one kept from delinquency.

I only have a few suggestions.

1. To avoid frustration when working on the 126, get a copy of the factory service manual. Forum sponsor carries them. Not expensive. Saves lots of time and swearing.
2. There are also maintenance sheets in the reference library section. List contains all the job numbers (from the service manual PDF's) that are required as part of ongoing maintenance.

Insofar as the work undertaken - timing chain etc, it's all sensible advice.
sprockets and cams wear as do the followers, occaionally the compensating elements on the hydraulic adjusters die, and there are valve lash adjustments that are performed by replacing the lash caps or shimming as appropriate - which will keep the valvetrain quiet. if you ever have to remove the cam oiler tubes then replace all of the plastic connectors. do not reuse them ever.

I view the fuel system with a holistic approach with an unknown vehicle.
Fuel problems can cause huge bills, so prevention is better than cure...
the downside is getting dirty, and it takes a fair bit of time to do it properly. Once done, it's good for a very very long time - just filters and routine servicing.

Here's my list.
1. tank strainer - remove.
2. flush tank with gerni, metho.
3. new tank strainer.
4. new pumps fitted (yep they do not last forever)
5. new filter fitted (always)
6. new filter on fuel divider (always with every oil/filter service)
6. check fuel pressure regulator for operation and static pressure. Replace if it leaks down.
7. absolutely remove the fuel pump relay, clean the PCB and resolder the relay connections and any other joints that look to be dry. ( this should be #1 on the list actually)
8 carry a spare jumper wire with 2 soldered pins (wrap it around the brake line) to use as a fuel pump relay bypass wire, in case the relay dies and you're a long way from anywhere....

Injectors occasionally get blocked after copping dirty shitty fuel. Pull them out and have them cleaned or buy new ones.
on the 560, the air shroud tubes around the injectors are prone to leaking with age. be careful with any R&R. use new orings and if possible new tubes. This can get $$$ if the items are old crusty and brittle, but if you don't replace the crusty parts, your engine will misbehave, and never run right. It's a great source of high idle issues and misfiring.

Or you can join your local Mercedes Club, most will have the manuals available to borrow from club libraries.

Firstly AMG thank you for that very comprehensive list. I didn't even think of a service manual. When i restored My Ford Marquis the manual was a huge assistance. They had everything down to measurements for badge placements.

I have worked on dads 380sel' fuel system a few times. A couple of fuel pumps And a relay in 20 years. Not bad but the Fuel distributor is due for a rebuild.

Next week i should be starting on slowly working through the Fuel system. I have never been the type to run a car out of fuel. For this reason and more.
