Webbo Posted October 29, 2016 Report Share Posted October 29, 2016 Hi, Thinking I might have a crankshaft rear oil seal leak on my 13\60, I took out the gearbox etc., only to find the oil appeared to come from the oil gallery plug at the top left hand side of the rear face of the engine. I unscrewed the plug, checked the thread,(seemed ok) degreased, and screwed it back with locktight threadlock. Needless to say, there was still an oil leak ( poss worse than before) , so I stripped it down again and it seemed that this is the only place where the oil is coming from. My questions are ; Why is there a plug there anyway? Can I glue this beast in permanently ? Is there anywhere else where oil can come from in that area that I am missing ? Thanks. Webbo.

Pete Lewis Posted October 29, 2016 Report Share Posted October 29, 2016 it seals the bore in the end in the oil gallery, its under full oil pressure and needs a copper washer and if needed some sealant like loctite 574 ( brilliant stuff) or simlar that seals hard when air is expelled from the joint, normal thread lock is not a oil tight sealant I wouldnt use a soft sealant may well blow out under the oil pressure. there is a welch plug/core plug above the threaded plug that seals the end of the cam bore , this is under less pressure but can leak, and dont miss out on the rocker cover joint leaking and running down the back of the head/block. if thats any help Pete Link to comment Share on other sites More sharing options...
Webbo Posted October 29, 2016 Author Report Share Posted October 29, 2016 Thanks Pete, that's helpful to know about Loctite 574. All the other areas you mentioned are ok. Webbo Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 29, 2016 Report Share Posted October 29, 2016 There are a number of loctite sealants I use 574 because we used it on truck production after many trials to make face joints gasket free and sealed for life It worked in many conditions and environments on engine gearbox and diffs pete Link to comment Share on other sites More sharing options...
