This kit fits ALL 116 123 and 126 4 and 5 cylinder diesels, 616 and 617 designation. This is one of the most common oil leaks on the older Mercedes diesels from 1977 to 1985. It is often found at the gasket between the engine block and the oil filter housing. A lot of oil under high pressure moves through the oil filter housing and over time the gasket hardens and shrinks. Leaks soon develop that can cover the floor and underside of your car with dirty black engine oil. Look on the underside of your oil filter housing to check for leaks.
Replacing this gasket can be a messy and difficult job. Without the right tools and some insightful tips included in this kit the job can really drive you over the edge. From my experience replacing many of these gaskets I have developed a couple special tools along with a few techniques to make this job go a lot smoother. You will need to remove the oil cooler lines and get under the car to complete this job. This kit includes a OEM grade specialty gasket (do not use an aftermarket gasket here), special metric allen wrench, two tie wraps and complete PDF instructions.
I highly - in fact - strongly recommend you purchase my special wrench set to remove the oil cooler lines from the oil filter housing. Normal wrenches will not work. If you can fabricate your own by cutting and grinding you should be ok.
