_ethrty-Andy_ 2132 Report post Posted July 25, 2012 no oillines there, it will be the rear main seal most likely, reletively common issue on the M20 engine. Quote Share this post Link to post Share on other sites

*Glenn* 854 Report post Posted July 25, 2012 Either check it yourself more thoroughly or get it checked by a professional. Sump gaskets are more prone for oil leaks than rear main seals... unless the seals have been incorrectly fitted by someone in the past. Give me a call if you need more info or help Quote Share this post Link to post Share on other sites
