I have an 89 300E - 3.0 engine. I purchased the two plastic pieces that fit in the center of the valve cover that hide the plug wires. Mine came undone and fried on the exhaust. Should I glue the bottom piece down to keep it in place? Unless I am missing something I see no way of keeping it in place.

Thanks,

And thanks Mr. Bible for all your help on the front timing cover. I cannot believe the local shop wanted $600.00 to do this!
