I own an 87 300e. I am looking to replace a cracked distributer cap. I found one for $63 U.S., is this a good price? Also, has anyone ever replaced this before? Is it difficult? Also, I think the seal on the front of my oil pan is leaking i.e. oil is all over it. Has anyone else had this problem? My final question is about a repair manual. Any recomendations on a good one? I found one made by bentley for $32 U.S. Thanks a lot everyone.
