    Looking to perform a coolant temp sensor replacement in a 91' M103 engine. The part is ordered and the job looks straight forward. The sensor is located on the head near the firewall. Went to a junk yard to practice the swap and was unable to get a deep socket over the sensor due to a metal...

    Hi everybody! First and foremost I'd like to thank the people of this community past and present for your generosity and expertise. You have been an enormous help and I couldn't have gotten as far as I am without you. Into the thick of it. I have a 1989 190e 2.6 California (Link to VIN info...

    Hello, my rocker panel needs replacement bad. Very rusted and eaten away. Has anyone ever done this type of job themselves or had someone do this work for them before? Thanks

    Hi All, We've been working on a W201 190E project, and have accrued a pile of parts that we're aiming to have out-of-house as soon as possible. Parts available include effectively a full interior (dashboard missing, as we'll be keeping that) as well as the engine and transmission. We have these...

    Quick question. There are two large bolts and one bolt on the head of the M103 that are unused. The smaller of the three bolts is next to the vacuum lines that lead to the Throttle body. If I had to guess, this would probably not be a coolant passage, but I could be wrong. The larger bolts...

    Hello friends! I purchased a 1990 300TE base 3.0 M103 motor with ~136k miles several months ago. I've read high and low here and elsewhere on the internet, tinkered, and sought some mechanic's advice on running problems it has faced as of late, but thought that the sharper minds on this great...

    Hi everyone, With the motivation and push from a few members (specifically H.D. ;)), I have decided to create a new thread to consolidate all testing procedures surrounding the M103 engine. Please understand that there may be minor variations between the engines (2 pin vs 4 pin/EGR/Non-EGR)...

    I have a w124 260e from 1986 with 205k kms. Unfortunately I have the problem of the camshaft and rockers which wear out prematurely, a fairly common problem on the early m103 engines. At first I wanted to buy all the parts from the dealer, but the price was too much: 1300€ for the 12 rockers and...

    Need some advice where to start looking at my 91’ W124 E300 with the M103 3l engine. The engine lacks of power, won’t go over 2500 rpm and won’t shift longer than third gear. Full throttle, nothing happens. Its like its got half the power it should. Starts and runs great, good oil pressure...

    Few years ago i placed my 300CE in storage and I think right now it's goot time to take care of it since I've almost finished my other projects. I'm not experienced mechanic, but since i also own old LR Defender, I have some skills and knowledge :D And here are my few questions to you...

    Well I couldn’t pass it up. After owning many W123,s W116’s, W140, W124s, I had to get myself into a W201. I came across this tired gem on Facebook market place, and instantly realized what it was and later realized how bad the condition was. So I ended up with a ‘93 W201 190E 2.6 Sportline auto...

    Hi All, My S124, M103 1991 300TE (wagon) idles at over 1,000 rpm and sometimes goes up to almost 2,000 rpm when it is in N or P. I am trying to figure out how to fix this myself. Firstly, I am missing the hose that connects the engine air filter to the front grill (see image red circle)...

    Hey everyone! I think I have reached my wits end with this issue and now I am hoping someone here can steer me in the right direction. I just finished the manual swap using the 717.404 getrag manual transmission and parts from a w201. The car was running well before, but now is consistently...

    I have a 91 300e that I have been suffering through trying to make it run and drive properly. The motor starts and idles beautifully. You can rev it up to redline in park with no issues and it will go if you put it in drive or reverse, but when it's under load (3k rpm or so), it stumbles and...

    Hey all, Down here in Texas trying to fix the car I'm buying from family. It has a new harness, cap, rotor and spark plugs... So we know it has spark. We are suffering from a fuel delivery issue. The car has had 2 new fuel filters within the last month after having sat for a few years. Both...

    I let a mechanic drive my 300SEL and he said it's a clogged catalytic converter. The engine is "choking" and when you floor it, it won't go above about 3000 RPM. There's very little power. That would also seem like a catalytic converter to me but -- when you step on the gas in park, the engine...
