Hello everyone!
Hello everyone!
First thanks winmutt!!
then i dident really know where to stick this so i figured this was the best place.
so here i go lol. im phill and I may soon be a owner of a merc.
Specifically a 1987 w124 300d with a om603 turbo in it.
I just had a few questions before going through with it.
1. They want 900 dollars i assume thats pretty good?- read rest.
2. What are common problems with these cars? what should i specificaly check for for when going to test drive / look at it?
its an auto obviously, i dont think they gave the om603 turbos manuals in the US.
the guy says the motors good trannys good but has faded paint and other cosmetic issues. tear in leather in seats etc.
and some body rust.
how are these things with rust?
any help would be greatly appreciated. i really do want to buy this car but if it wont be worth it then ill have to wait till another deal comes my way.
Thanks a ton guys im really hoping I get this car!
These are great cars! and may people have converted them to manual transmissions
Things to look out for are head casting number **** ** 18 ** by the 2-3 injector from the front
you want a casting number above 18-21 replacement any 14-16 are prone to cracking if they have ever gotten hot!
Good to know. Im pretty sure I need to listen for when its runnung, such as bad hydro lifters unsmooth idle
Check to see if the upper radiator hose is already pressurized when its still cold or immediately after starting before it gets warm that will tell you if the head is cracked and pressurizing the cooling system!
also look in the oil for any signs of water or milky oil
Wow. I never even thought about the pressureized coolant. I appreciate these tips rmmensly.
The OM603 have a cast iron block and aluminum head but they are much more powerful compared to the older 300d with the 3.0 five cylinder OM617
the om603 will last a very long time if taken car of 400k +
yea thats the only other thing i was wondering about its got right under 300k so im not sure if its gonna take the abuse i plan for it
but assuming all is right in the car its worth 900 no?
I bought my 87 300sdl totaled for $600 + towing charges so if it moves under its own power I'd say it's a deal!
plus if the engine ever dyes it will give me an excuse to get an OM606 to put in it's place
So I went and took it for a test drive today. A little dissapointed. The car runs and shifts fine but theres no power. Makes me think the turbos blown I felt no spool or anything.
The underside of the body wasent bad a little rust on the corners near the wheel wells.
Un fortunatly the intake manifold was a 14 number. So thats a bummer. The hydro lifters dident sound very good. And the interrior was pretty rough. Seat dident move so thats an issue because I couldent drive very comfterably
the only thing that makes me still want it alot is its got so much potential. And he lowered the price for me. From 900 to 700.
700 for am essentially running om603 w124... What to do. What to do.
Power could be related to some vacuum lines I had a bunch of vacuum leaks and the ALDA wasn't getting boost so it never enriches the fuel mixture! fixed that and bam more power than I could imagine!
Yea this is very very temping for me. At 700 for essentially a good running car I almost cant pass it up.
And thanks alot man for replying to my thread, I need all the help I can get. Coming from gas 4 bangers fwd this is a complete 360 lol.

Makes me think the turbos blown I felt no spool or anything.By pass the over boost protection solenoid on the firewall. The hose runs from the manifold to the solenoid to the grey box on the IP known as the ALDA. Googling will explain this. Dont worry about the power, its there.

Ignore what everyone says bad about the #14 heads. If it made it this far its going to keep going. Plenty of original heads on cars with 400k and up. A #17 can be found pretty easily from the SDL's. Of course you want an 18-21 but really its not a deal breaker at that price.

here are some pics.
i have done a good amount of research and planned on adjusting/ cleaning the ALDA or removing it. i hear it does wonders. I think i would also try to adjust the timing on the IP. couldent hurt.
i live in maryland with every single season being intense. lots of snow rain etc. rust is common and there wasent that much
the best way to describe the sound is the engine sounded like 2nd car in this video

here are some pics
yea paint is pretty rough and im in desperate need of a project car. and love to tinker. so i think this is going to be alot of fun.
So its official. i will be the owner of this 87 300d soon im finally officially a merc owner lol.
Im really excited to see how much I can improve it with out parts. Just removing or cleaning or adjusting etc. its going to be alot of fun
The second car in that video sounds like it needs the injectors rebuilt not an uncommon thing at that mileage it can cause an excessive clack/smoke at idle if they are worn not a big deal
A new a set of tips and nosils are around 100-120 bucks and if you can do it you self It doesn't cost anything if you have some descent tools other wise you can send them out to be rebuilt for not to much.
I had never done it before but there was a whole article about how to do it.

also my car was making a lifter tick when I got it so I ran some BG 209? engine flush through it and some fresh synthetic oil quieted it right up!
Yea I consider myself pretty capable so I'll probably try that.
But I also was thinking about running a can of sea foam or simmalar product through it hopefully that'll help. And obviously a good routine matinence sorta thing. Like oil change, filters, etc.
And thanks for the link man!
Ive read good things about seafoam, havnt tried it yet.
I use Lubro Molly diesel purge, and ive always liked the results that has given me.
Congrats on your first benz purchase too! Great great cars.
What kinda "gas fourbangers fwd" were you into previously?
I like sea foam it also works well!
