Quagmire Posted December 31, 2007 Share Posted December 31, 2007 Hi, I have a 2.25p 90, which developed a nasty clonking noise from the engine last week. I stopped pretty much straight away and the landy was towed back for examination. The noise seemed to be coming from the rear of the engine at the head and first thoughts that unleaded fuel in a leaded head combined with continuous high revs (i do lots of motorway miles) had killed the top end. However on inspection there was nothing found in the head that would account for the noise, so we dropped the sump and had a look. The big end on number 4 had some play. This was examined and we found no unusual wear, BUT when i undid it it seemed a little on the loose side . It was decided to reassemble it and torque it up properly and see if this made a difference and it has. No more play. The others were checked for tightness and although they were all slighty under the book figure none was as loose as this one. Has anyone seen this before where parts have come loose? The workshop manual does not mention loctite or any other method of preventing parts coming undone... Finally, can i replace the shells on this cylinder without getting any machining done, and if so would it be a good idea as a precaution? I have not checked for ovality but considering the state of wear on the bearings i dont believe that i would find it out of tolerance.
