M112 V6 M113 V8 How to Fix Common Valve Cover Oil Leaks - On Demand Video

You SHOULD do this yourself. It is the only way you will know it is done RIGHT!

WHY does Kent stress doing this yourself - because my shops do not take the time to thoroughly clean and prep the covers for the proper sealant, or they do not use the proper sealant or use quality gaskets, or torque the bolts properly.

M112 V6 and M113 V8 Mass Airflow Sensor Intake Air Critical Seals

Set of two seals of differing sizes for the intake elbow below the Sensor.

These seals getting totally neglected. I consider the bottom one the "forgotten" seal on these engines. They can be very frustrating to change out if you don't know the right sequence.


M112 V6 and M113 V8 Drive Belt Idler Pulley

Guaranteed to go bad between 70K and 100K miles. Easy to check. Might even be able to hear it failing.

M112 V6 and M113 V8 Water Pump Metal Pulley

1998 to 2006. You will want to replace this for better belt life if the surface is worn or rough.

This pulley is usually replaced when you replace a worn-out and high-mileage water pump. If your pump is good and you just need to replace the pulley, you can do this very quickly by just loosening and dropping the drive belt.

This will solve your hard to remove cap for years to come. For 1998 to 2006 models

Mercedes BlueTec AdBlue Diesel Exhaust Fluid - 1/2 Gal. Bottles x 2

Don't use cheap Blue DEF or your pocket book will be sorry. Only use fresh AdBlue - Made in Germany

The reports of BlueTec engine emissions failures are numerous. Failed NOX sensors and emission fluid injectors are often traced back to using old or cheap DEF fluid. I know it is easy to be enticed by the cheap price.

Removing the front rubber engine mounts requires getting under the car and going up inside a hole in the subframe to remove the main bolt. And it can be a bear! I don't know who they hired to tighten these at the factory, but he must have been a brute.

380 engines tend to run hot. As long as it is not too hot it won't hurt the engine but that extra heat is not kind to rubber and plastic parts.

380 420 500 560 V8 Fan Clutch Replacement Kit

Watch the engine temp. If it likes to creep up especially at idle it could be a worn out clutch. Watch the video below for more explanation.

This fits all Mercedes V8 engines listed in the title from 1981 to 1991 including the sedans, the SL and SEC models. I compare fan clutches to shock absorbers. They wear out slowly over time and you don't feel or see the difference until you actually replace it with new.

So often neglected - yet critical to preventing pre-mature or catastrophic engine failure!

Why is this so important? It is primarily due to the age of these cars now and the fact that lurking problems can be hidden from visual inspection. There is not ONE diesel that Kent has looked at in the last five years that does not need this service! Even ones with under 150,000 original miles.
