Kent and others have seen valve cover leaks return within a few years after resealing. Some feel this may be a design flaw, but I contend the job was never done right in the first place. Let Kent explain why the leaks come back...
I know that many, including some coil-over sellers, recommend just leaving the original pump and hoses in place and plugging them where they attach to the four struts, but I can almost guarantee you will have problems in the future, either with a noisy failing pump, leaking hydraulics, or a possi
They can often be reused if you carefully cut the hardened rubber away from the coupling. If you prefer new here you go. Three are included here and that is the total used on your V6 or V8 engine up through 2006.
Depending on the age and mileage of your V6 or V8 engine, this part may or may not need to be changed when you replace the breather hoses. You can check before ordering. If the part is still soft and rubbery, then it most likely can be reused.

This kit will allow you to properly fill any 722.9 7 speed automatic transmission as well as other cars that use the underfill method.
Anytime you need to replace your rear shocks/struts, you must drop the rear control arm. If you are doing other rear suspension work, you may need to drop it as well. Kent came up with this tool kit when he was converting his SL500 to conventional coil-over shock absorbers.
You must drive this star bit into the head of the damaged bolt with a hammer, but it will hold. The bolt will then need to be replaced. Watch the video below as Kent will explain how it works.

In this 20-minute instructional video, Kent will show you the steps on how you can replace the "hidden bushing" in the rear control arm by yourself without having to take the control arm off the car.
I can now offer a unique digital meter and several attachments in a convenient carrying case that I can grab and go with anytime. Are you tired of fussing with your standard meter straight-tip probes? I think they are worthless.
30 light bulbs total in this assortment. PLEASE NOTE: These may not be every bulb you will need for every model, but you will have extras on hand. These cars are OLD, and most of the bulbs need to be replaced. They even start to loose some of their intensity over time.
When you need the torque, this will deliver.
This is a complete kit. Aftermarket new plastic breather tube with rubber attachment elbows, one new clamp, and a zip tie. You can see below how it installs on a turbo 300TD wagon. Watch the video for more specific details.

This is part 3 of a three-part series on converting your 2003 to 2006 SL500 to coil-over shock absorbers. It is 27 minutes in length. The complete series is 1 hour and 27 minutes and was too long to upload as one video.
This is part one of a three-part series on converting your 2003 to 2006 SL500 to coil-over shock absorbers. It is 18 minutes in length.
This is part two of a three-part series on converting your 2003 to 2006 SL500 to coil-over shock absorbers. It is 41 minutes in length. The complete series is 1 hour and 27 minutes and was too long to upload as one video.
High quality fast break in pads with special coated anti-squeal pad bonded to the back side of the pad. We include 4 new sensor wires and a small ceramic brake pad grease to lube the pad edges and the pins. ( no need to lube the back side).
This will be instructional information that you can not find anywhere else! The focus of the 25-minute video will be on removing and replacing the oil cooler thermostat once the oil filter housing is removed for a 1977 to 1985 engine ( excluding the 190D).
Want to find out if your oil cooler thermostat is working correctly? In this 22-minute video, Kent will take you through a test sequence that you can perform in your garage. Please note that this video DOES NOT include details of removing or replacing the oil filter housing.
We know it is a surprise to many owners to discover there is a small thermostat inside the oil filter housing. Rather than write about it, watch the video below and Kent will explain the theory of operation and how to get it it.
In this video, Kent will show you how he used this unique heater to remove a stuck oil cooler hose fitting. It had to get really hot, and using a propane torch in this area would not have been a good idea.
Set of two new aluminum washers as shown.
Getting that oil pressure line off the bottom of the oil filter housing on the 1977 to 1985 240D, 300D, 300TD, 300CD, and W116 300SD is tough. If you break the line or damage the nut, this part is no longer available new.
Kent was a little skeptical when you first used this—it sounded like it would be too good to be true. The first use was getting some rusty bolts off the Garrett T3 turbine housing ( some of you know the pain there!). Well, it worked, and it worked very well.
In this 5-minute video, Kent will show you how to use our digital battery meter to determine the health of your battery. He will also show you why you can not rely on a volt meter to give you anything helpful other than the "surface voltage."
Finding W116 front seats in even half of this condition is almost impossible. These are amazing for the age. No rips, tears, worn spots, and solid padding. These came out of a 300SD with only 130,000 original miles and have been in storage for ten years.
If you own an older Mercedes with the 7-speed 722.9 transmission and the car has over 120,000 miles, the day may come when the transmission will suddenly not shift or not shift past 2nd gear. This is more likely to happen if the transmission has no fluid and filter changes every 40,000.
This OEM thermostat from another engine fits perfectly in the OM617 diesel engine. It does require a special rubber seal, which we include here.
LOOK closely at the picture. This is exactly the hardware you will receive! Grab bag of fortune!

This is what you need as the final touch to get your later 450 engine to run smoothly. New Distributor cap, Bosch or Bremi rotor, and new Bremi wires. If you need spark plugs as well please order separately. See related products below
New tensioner as shown. No specific instructions are available but this can be installed from outside the engine once you get access the the hold down bolts.
Removing the valve body is not difficult, but it is fraught with risk. It is easy to damage the conductor plate if not removed properly, and that can be a very expensive mistake.
If you are planning to remove your 722.9 conductor plate for inspection or repair, you will want to take the time to thoroughly clean the plate, the valve body, and the solenoids. No cleaning agents or foreign chemicals should be used.
I call this the hidden and forgotten bushing. Why? Because you can not see it to inspect it, it hardly ever gets changed. When these bushings wear out you will feel "weird" movement in your rear end, especially going over rough ground.

They started using 18 mm hardware after 1996. Most wrench kits use to not even have an 18mm combination wrench - let alone a long one ( measures 11 inches long).
Excellent used prechamber as shown.
To to prevent potential fluid weeping on the end of this pipe you might want to replace them if you end of removing the pipe in your procedure.
Since there are no dipsticks on these transmissions, the DIY way to check fluid level is from under the car with a touch-free thermometer to measure the heat of the transmission fluid BEFORE setting the correct level. Instructions are included with my full 722.9 transmission fill kit.
Very nice set with silicone copper core wires. See detailed pictures below. Two coil leads of different lengths included. Check before ordering as this fits these models from the early 1990s with dual distributors in the front of the engine. 400E. 400SE.
