You might be surprised to realize you spark plug holes need cleaning - and yes some REALLY need cleaning! This 5-minute video will demonstrate Kent's method of cleaning the threads in the cylinder.
This video will walk you step-by-step through the proper procedures for doing a full compression test on your older V8 Mercedes Engine.
Replacing a distributor cap is easy right. No problem?? If it were I would not get so many emails and why the engine won't run right after changing the cap and rotor. This is a short eight and a half minute video but the tips I share could save you some big headaches.
This is one of those severely neglected parts that seems never to get changed. This is the FIRST thing you want to look at when the engine won't start, starts and quits, or misfires erratically. This is a quality German-made Bremi aftermarket cap.
If your V8 is running hot or temp gauge is moving you may have a bad sending unit. Located at the front of the engine. Easy replace. Drain one gallon of coolant out of the radiator before removing it.

These are three inexpensive parts that seem to never get replaced when they wear out. If "mechanics" miss these items. Are you losing coolant? Are you losing windshield washer fluid? Do you have unsightly oil on your right valve cover?
Hard to believe we took so long to come up with this tool. It was Gerson's genius that made it happen. The secret turned out to be the hook that keeps the tool in place while stretching out the rubber donut. Wow! What a cool tool.
Best engine oil filters for your classic R107 or C107. As seen on Cherry.
These will fit all 1976 to 1991 4.5, 3.8, 5.0 and 5.6-liter V8 engines with Bosch C.I.S fuel injection.
Do not let anyone convince you to install some super platinum, iridium or kryptonite spark plug in your SL V8. They are just not capable of handling the richer fuel mixtures associated with these older engines.
Have you ever had a hard time finally a very small coolant leak? Do you find yourself adding small amounts of coolant but can not see any leak? Is there a funny smell coming from inside your Benz when you run the heater?
In this video, Kent will walk you through the steps needed to convert your older Brake Bleeder tank to one that can continue to bleed brake systems as well as pressure test radiators and cooling systems.

If you own one of the early Mercedes overhead camshaft engines from the mid-1950's up to the mid-1970s that have mechanical (non-self-adjusting) lifters this is a MUST HAVE tool!
This is the hose on the left side of your engine that seems to always rot and leak power steering fluid. If you look closely at it you will most likely see small cracks in the hose. This is the larger size hose used on those early models with power steering from the early 1960's through 1976.
This is the very best hose Kent has found to use to install spark plugs in restricted spaces. Watch the video below and he will demonstrate.
Keeping your throttle linkage ball sockets and pivot points lubricated extends the life of the parts and maintains top performance for the engine as well as some of the later transmissions.
For a number of maintenance operations, you need to be able to turn the engine over by hand. This includes valve adjustment, timing chain replacement, injection pump timing on diesel engines, checking and setting internal engine timing, draining the torque converter, and others.
This is not a complete instructional video on how to "overhaul" the M116 and M117 D-Jetronic fuel injected V8 distributor. There is lots of information out there on installing new points, setting the dwell and timing, replacing the cap and wires, etc.

Learn all the tricks to adjusting the valves on your older Mercedes V8 engine.
PLEASE NOTE: This is NOT a complete instructional video on how to install a new timing chain in a 1970 to 1991 M116 or M117 Mercedes V8 engine. Rather it is a collection of "tips" to help you prevent running into trouble when doing this job yourself.
In this video, Kent will walk you through some initial steps you can take to try to solve a rough running problem on an early Mercedes V8 engine with D-Jetronic fuel injection. Please note that this is an introductory troubleshooting video. It does not contain any actual repair information.

New O.E. cap as shown. Alert: These are almost out of production.
Exceptionally nice set of high-performance spark wires as shown. These should be replaced approximately every 80,000 miles for peak performance.
If you are a 1969 to 1991 V8 you should have some extras of these on hand. They are inexpensive and should be replaced anytime you remove your valve covers. The gaskets will keep a good seal longer than the bolt washers.
These will fit all 1976 to 1991 4.5, 3.8, 5.0 and 5.6-liter V8 engines with Bosch C.I.S fuel injection. PLEASE NOTE: These spark plugs have an aluminum end cap that does screw off. You will receive the plugs with the end cap installed.

One of the most often neglected easy and inexpensive maintenance items I see on gas engines. Why do people think that spark plugs will last forever or that it doesn't matter what type of plug is used! Aren' they all created equal?
This is a VERY common maintenance item on the older Mercedes V8 engines. If they are too old they will leak. If they are not put on properly they will leak. If you do any maintenance (ie, valve adjustment, clip replacement, timing chain, guides, etc), you should have this kit on hand.
You can not believe how many problems Kent has seen over the years as a result of the camshaft oiler tube falling off inside the valve cover! It is held on by inexpensive small plastic clips and guess what happens after 15 to 20 years? Yes, that is correct.
Kent will show you the proper way to remove and replace a V8 valve cover gasket so you won't have oil leaks after installing a new one. This is a common maintenance item.
UPS GROUND ONLY: This is the best spray can paint Kent has found to detail the semi-gloss black parts on your Benz. It is not easy to find a good spray can paint!
2 large style clamps to be used on upper and lower radiator hoses. Use these to replace your thermostat or water pump without having to drain all your coolant out of the radiator. Works on medium size coolant hoses also.
Want to try to make your car's engine and engine compartment look like it just came off the showroom? Would you like detailed information on the chemicals, brushes, tools, and procedures Kent uses to get his engine compartments looking so nice?
If your engine is just running hot, it may be due to a plugged radiator or possibly a stuck thermostat. If your engine is just losing coolant it could be a leak in the water pump, radiator or hoses.
The digital PDF instructions will walk you through the install and detailed photos will visually assist you step by step. PDF is 4 pages long.
