The Best Car Ever Made Will Live Forever

Many agree. This in the ONE. A 1983 W123 White 240D with manual 4 speed transmission and manual windows

Look what just arrived at Mercedessource. It was 40 years ago and Kent remembers clearly the first time he really noticed a Mercedes Benz. In fact it turned his head when he walked by. It was 1980 and he was walking around the Pamona Car Swap Meet in Southern California. To be continued...

Doing a Rolling Restoration to Keep the Motivation High

Follow along as Kent does just that on his 1983 R107 380SL

So you want to pick up and restore an old Benz - maybe even a classic SL convertible? I have a recommendation. Bring home a running and rolling restoration project. Do NOT bring home a project car that is not running, needs a repaint, and shows severe signs of neglect. I get people disagreeing with me all the time on this, but you can not believe how many "project" Mercedes I run across that people have given up on. Follow along as I do this on a loved 380SL. You will understand better why I am such a believer in approaching any old car project this way.

What is Showing Up at the Shop: Fall 2019

A few very interesting cars indeed.

Of course, the 280SL (Happier) in the foreground has been around for a while, but check out the Mercedes on the lift and the one directly behind it. Both of these are pristine examples of very desirable models. The gold sedan is a 1972 300SEL 4.5 with 78,000 original miles. See the video links below to watch the series of videos as I bring it back to life after sitting in a heated garage unused for the past 12 years. The wagon is a 1981 (first year of the turbo) 300TD that has been garaged and driven lightly for the past 20 years.

Diesel Engine Removal Checklist:

Preparing an Old Benz for a Long X Country Road Trip

Specifically 25+ years old. The older the more work you may need to do

Have you ever wanted to make a cross-country road trip in a 30 plus-year-old Mercedes? I have always thought it a little “risky” unless the car was thoroughly checked over. I usually recommend if you are purchasing a car that old from “afar” you might want to consider having to truck it to your location. We have heard from a number of our customers who have made such a trip successfully and suggest I might be a little too cautious. A couple years ago I sold a 1980 240D to a buyer on the East Coast. I suggested he truck the car back east but he was adamant about driving it.

What Got Kent Into Mercedes Benz 25 Years Ago

Let Kent tell you how it happened... just to "help" an old pilot friend out

"So how did you happen to go from being a pilot to getting involved with older Mercedes Benz?" This is a question that Kent gets ask a lot. Most of us can recall those seamingly insignificant events that end up changing the whole course of our lives. CLICK ON THE PICTURE TO LEARN MORE. So was the case here. It all started with a 1982 240D in the early 1990's. Watch the video below and he will explain how it all happened and why he continues to be passionate about old diesels. 

Will They Really Go a Million Miles?

It takes a lot more than hype to make a diesel engine last!

I am sure you have heard it before, "Oh, these old Mercedes diesels will go a million miles." Sounds pretty good, doesn't it? But maybe it sounds too good to be true.

Kent's 10 Most Neglected Maintenance Items on Older Mercedes

Not necessarily all issues, but here is his list of those things often overlooked on a 25+ year old Benz

This week while working on “Fritz” (my 1980 280SE Euro W126), I started making a list of all the things I will need to fix or service on the car. As I looked at the list, I said to myself, “ I have seen this list many times before!” I thought the list would make a good video series. CLICK ON PICTURE TO READ MORE.  I Chose to title it: The 10 Most Neglected Maintenance Items on Older Mercedes. Please keep in mind that my “top” ten list may not be the only things wrong with an old Benz.

Save the V8's

Hard to believe Mercedes made one style V8 for over 20 years.

I must admit I have a soft spot for the old M116 and M117 Mercedes V8 engines.  From a 3.5 liter when it was first introduced in Europe in the late 1960's, to a 5.6 liter at the end of production in 1991, the basic engine did not change all that much. I liken it to the German version of the Chevy 350 engine. Of course, it went through a lot of subtle changes as well as revisions to its fuel injection system. But the fact that the valve cover gaskets did not change during the 20 plus years of production tells its own story.

How to Search Kent's Videos

With over 1100 on Youtube and almost 200 on his website this will help

Almost everyday now we get requests for help trying to find a specific video. As of March 2017 Kent has produced almost 1300 videos and on average 3 to 4 new videos are being posted every week. It is hard for even us to keep track of them all and we can not answer questions unless YOU TELL US the specific video you are asking about.  Here is the best way to search Youtube video content:

My NUMBER ONE Warning That You Should Heed

There are a number of things that can break on an old car but this one will really leave your stranded!

From my own experience and from hearing from lots of other's experiences I can not stress enough - DO NOT NEGLECT YOUR IGNITION TUMBLER AND STEERING LOCK ASSEMBLY! If your key is starting to "stick" or "catch" in the tumbler then you shoud replace it before it will not turn and leave you stranded!  In the picture here the owner tried to drill it out, but let me tell you they do not drill out very well. If you neglect this warning you could end up spending hundreds of dollars instead of less than $50 for new new tumbler and keys.

Whats up with all these issues with Diesel Pre-chambers?

Kent explains how the prechamber works, what can go wrong and how to fix problems

Fuel Leaks. Air Leaks. Rough running diesel engine. All around your diesel injectors! Collar nuts might just need to be tightened, but could be too worn and need replacment! If you are having problems with your diesel prechambers we have tools and parts to help!

Below is a great Video Kent did on all the in's and out's of Prechambers and will explain in detail what each part is, how it works, and how to replace it. Watch the other two videos to see how the tools work along with a warning if you plan to remove a pre-chamber. 

Finding the Leak in the Suspension of an Airmatic equipped Mercedes

If you can find and repair the leak (s) yourself you can save Thousands $$$$

It is the end January 2017 and Kent has just finished filming a new video on how to find air leaks in an Airmatic suspension.  There is nothing like driving a Benz with Airmatic, but there is a price to pay... and that price does not need to be that much if you learn to diagnose and repair the leak (s) yourself. Do not be afraid to tackle these systems! Kent will make it easy for you to save lots of money if you are willing to learn and apply knowledge. 


New Ways to Thoroughly Clean Gas Engine Fuel Injectors

Many of the older injectors will need to be "back flushed"

Not all older MFI and CIS fuel injectors are "restorable." Some are just plain worn out. If the tip is worn out or damaged there is nothing you can do to repair that. There are no replacement parts available for Bosch mechanical gas fuel injectors. You can not replace the tip. The fuel injector is sealed up tight during the manufacturing process.

Full Service Brake Tips

Do a full brake service on your older Benz BEFORE hitting the road.

This is that time of year we pull our prized Mercedes out of winter storage and get it ready to hit the road. Just today (April 8) it was 72 degrees and bright blue skies here in Bellingham. Tomorrow I am going to put the top down and take Happier (my 280SL) for a tour of the countryside. :-)

250SL Brakes Rebuild or Replace, Shrunk SL Top, Cleaning Rotors, 300TD SLS

When it comes to brakes nothing beats prevention. The same could be said for the self leveling suspension on a 300TD wagon. Work starts this coming week on helping the owner find out why his rear suspension is acting so badly and what it is going to take to fix it.
