Of all the upgrades for diesel engines that we offer on this site, I believe changing over to Monark injector nozzles will give you more performance improvements for the money that any other single product. From our own diesels to the glowing reports we hear from our customers - you may have a hard time believing just how try this claim is until you experience it first hand! And Monark nozzles are probably the last of a breed. Yes, they are still manufactured in Germany...
Recently, I set out with the goal to provide our customers with all the resources they would need to troubleshoot and repair the brake systems on their own cars. As your favorite Benz ages brake problems will arise and they can sometimes be difficult to diagnose. Since brakes are a safety related system it is also VERY important that any repair work be done properly and with great care.

Description: Single replacement 30 micron filter element for our standard FM 100 filter used in all our conversion systems. Comes in box sealed in plastic for long shelf life. This element is used as a first primary filter when two filters are used in series. It is also a water separator. I recommend using two filters if you re-fuel on the road. Buy using 2 filters in your system you can increase filter life and extend top engine performance during more of the filter life.

For me 2010 is going to be the year of the transmission. It is hard to believe I have been working on a transmission repair manual for the past 6 years I Just the other day I was looking at an email I wrote to a customer in 2006 telling him the transmission manual should be out by the end of that year! Each year we receive an ever increasing number of requests for transmission help. Neither these transmissions nor myself are getting any younger so I decided I had better get my act together and deliver on my promise.
Troubleshooting an annoying shift problem must first start with the vacuum modulator. This vacuum control unit mounted on the side of the transmission must be tested and adjusted to specs BEFORE you move on to other adjustments. Unfortunately this can not be done by guess or by feel. There is a pressure port on the side of the transmission that you must tap into and connect to a pressure gauge. The engine must then be started and the modulator adjusted to a set pressure for that specific transmission. It is not a difficult job with the proper test tools and information, and can be done in less than an hour. Too much pressure and abrupt shifts will occur. Too little pressure and you may experience slipping or flaring during shifts. My kit with help you do all the above with ease.
In the 45 plus years that I have been working on old cars I have tried every product on the market that promises to fix rust. Almost all of them do not live up to their promises nor do they product permanent lasting repairs. Even welding does not last if the weld line can not be treated properly on the back side of the weld.
Nothing works like Miracle Paint. Their new heavy duty (thicker formula) stands above the competition and is ideal for making the types or repairs you see in the picture below.

Brand New Release! This manual writing by Kent Bergsma will walk you step by step through the process of removing and replacing a Mercedes steering lock assembly. This can be a very frustrating job if you don't know some of the factory secrets. For anti-theft reasons the engineers designed it to be very difficult to remove!
Includes 30 quality red plastic clips, a removal tool and detailed instructions. There are a number of reasons why you would want to remove the center side trim on your older Mercedes. You may just want to clean and detail behind them (it does get pretty dirty back there over the years). If you are repainting your car removing the side trim is a must for a quality job. There could be rust growing out of the holes on the back side of the strips (do not let this go - see my Miracle Rust Cure products). Or you may have one or more loose or damaged side strips. The biggest problem in removing these strips is that the plastic snap clips often come off with the strip hold down pins.

Follow along as I take you through the products and procedures I will use to repair the rust on my 6.9. I have been working on rusty old cars since I bought my first Model A Ford when I was 13 years old. I have tried every product imaginable. Very few live up to their claims to make it go away and not come back. Even welding in new metal is not a guarantee that the rust will not come back. You should see some of the dozens of examples where I have seen the weld seams rust from the inside out because they were not properly coated and protected from moisture on the blind side! And NOTHING rusts faster than an oxidized weld seem. I have come to believe that unless you are restoring a valuable collector car, one should stay away from sheet metal weld replacement.

I have never been impressed with the rubber vacuum hose found on older Mercedes diesels. I don't think the engineers ever anticipated how much abuse or how long these hoses would need to last! Over the years I have seen way too many vacuum related problems lead back to a failed hose connector or short hose length. The combination of high heat generated in the engine compartment as well as both internal and external engine oil contamination are the chief causes of its early demise.
Timing chains have been used on Mercedes engines since the early 1950's. My 1953 220 has an overhead cam six that is driven by a twin row chain - similar to engines well into the 1990's. Timing chains may be old technology, but they are proven and they work for long periods of time (provided the engine receives proper service).
WARNING: Timing chain failure is the NO. 1 cause of catastrophic engine failure in these old engines. If it lets go the valves will hit the pistons. If it comes off at high speed, the pistons can be damaged and the camshaft can driven right out through the valve cover!
CAUSES: There are a number of reasons for excessive chain stretch / chain failure.
New in 2010! After years of receiving email and forum requests for tech help, the problems most customers have and the questions they ask start to follow a very predictable pattern. So to better help you find out what is wrong with your Mercedes and what parts you need to fix it we are launching a new WHATS WRONG section on our website. Each category will list the common problems, what steps need to be taken to fix them and links to the parts and instructions needed to tackle the repairs. Where applicable you will be directed to one of Kents kits or manuals for help in diagnosing your problem. We know that isolating the problem can be more frustrating than fixing it!!!
Over the years I have used many different products to try to adhere chrome and trim pieces to body and interior panels. None has performed better for me than E6000. When dry it holds like nothing else. It never dries totally hard so you can always cut it with a sharp razor knife to remove the part in the future. Great for adhering bumper trim and rubber, side mouldings, and interior wood and trim. It does take overnight to dry, so you will need to something strong to hold it in place while drying. Note: For bumper rubber I have even driven the car up against a wall to hold the rubber in place while it dries overnight!
I don't know about you, but I just can not stand loose trim. Kent Bergsma
