I saw a reference in this forum a while back (unable to find) about a MB sealant that could be used to plug a leak from the timing chain cover on an '87 SDL. Please supply me specifics on this and how durable would this be considering the tremendous heat and pressure. I'm considering the short term fix for now and I'd like to direct my machanic on what exactly I'd like done. Can this be purchased from the PartsShop?

thanks!
