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. Do not use the old gaskets and sealing washers or they will leak! This kit will fit all M116 3.5, 3.8, and 4.2-liter V8 engines from 1969 to 1991 350, 380, and 420 models. All M117 4.5, 5.0, and 5.6-liter V8 engines from 1971 to 1991 450, 500, and 560 models. As seen on Cherry. CLICK HERE to watch the full video series on Kent’s R107 rolling restoration.
Product Details
Kit Contents:
- 2 high quality and tight-fitting valve cover gaskets ( some of the cheaper ones will LEAK!)

If you don't want the new gaskets to leak, we highly recommend you use a small beam style torque wrench. This is the most accurate type when working with low torque settings. See related products below:

M116 and M117 Valve Cover Bolt Copper Sealing Washers Set of 8
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.
