tpk241 Posted April 28, 2007 Share Posted April 28, 2007 Hi All, Hope someone can help me diagnose the problem i have. Coming back from sodbury couple of weeks ago near to home the discovery started making a faint knocking / grinding noise. I took it easy to get home and parked up. After coming back from holiday and working on disco today I started it to turn the wheels full lock and engine stalled. Symptoms now are: Eventually started whilst giving it gas, knocking noise evident, lots of smoke and wont idle needs gas to run. So I switched it off straight away. BTW the engine is a defender with about 100,000 on it. Inpspected engine & removed rocker cap, lots of steam/smoke (not sure) ... Removed belts to check wheels, all moved ok. I fear the worst, someone please HELP ! Thanks in advance TPK Quote Link to comment Share on other sites More sharing options...
steve b Posted April 28, 2007 Share Posted April 28, 2007 Hi is it 300TDi defender eng in a disco ? smoke/steam from rocker cover immediately on start up suggests blown head gasket.. is it really a "knocking" or more of a banging? How's the water level (300tdi check header tank and at thermostat housing) .They usually idle still if head gasket is gone though. ........however metallic knocking & won't idle suggests cam belt may have slipped a tooth, when was cam belt last done? the grinding noise you mentioned on the way back from sodders also suggests cam belt . with the rocker cover off did all the push rods look straight & all the valve stem caps in place? some food for thought maybe Steveb Quote Link to comment Share on other sites More sharing options...

Roverdrive Posted April 28, 2007 Share Posted April 28, 2007 Sounds like a head gasket to me. Quote Link to comment Share on other sites More sharing options...
