alanlambert Posted January 2 Report Share Posted January 2 (edited) Only when hot, and no fluctuation on oil pressure gauge Could this be a symptom of a sticking pressure relief valve ??

mike_sekinger Posted January 2 Report Share Posted January 2 Is the buzzing associated with a particular rev band or also present at idle?

alanlambert Posted January 2 Author Report Share Posted January 2 Hi Mike, Only hear it when bonnet open and its there when hot at all revs, well from tickover and increases when its revved up. Initially suspected it was a bearing on the front of the engine first but traced it to the oil cooler pipes with a stethoscope when over a pit. Thought it might be an issue with oil cooler pipe de laminating inside, but changed them to no avail. ? Quote Link to comment Share on other sites More sharing options...
mike_sekinger Posted January 2 Report Share Posted January 2 Could it be from the oil pump itself? That would probably transit to the oil lines. 1 Quote 1996 Esprit V8, 1998 Esprit V8 GT, 1999 Esprit S350 #002 (Esprit GT1 replica project), 1996 Esprit V8 GT1 (chassis 114-001), 1992 Lotus Omega (927E), 1999 Esprit V8SE, 1999 Esprit S350 #032, 1995 Esprit S4s, 1999 Esprit V8 GT (ex-5th Gear project), 1999 Esprit V8SE ('02 rear) 1999 S350 #002 Esprit GT1 replica Link to comment Share on other sites More sharing options...
