Geko Posted August 21, 2017 Report Share Posted August 21, 2017 (edited) The front engine block sump bolt thread on TR2-4 is a textbook source for oil leak. Forget the washer in refitting the sump bolt or try putting a longer bolt if the thread is damaged and the aluminum block will crack giving way to oil leak "from the sump". This adds up to the long list of potential leaks from the engine block. Edited August 21, 2017 by Geko Quote Link to post Share on other sites
