Bomag Posted June 15, 2012 Share Posted June 15, 2012 Ive just had the cambelt changed on my 300TDi and while it was being done the front thrust washer on the cam was renewed as the cam had moved out 5mm. The rocker assembly was also removed to look down the pushrod tubes. On picking the vehicle up the mechanic said about it being very lumpy on tickover, but as the engine was now warm tickover was fairly smooth. The next morning it felt like it was ticking over on 3 cylinders till warm and when accelerating was chucking white smoke out the back. Once warm no smoke. The vehicle has now done over 200 miles since the belt change. Prior to belt change the engine ran sweetly from start up. Does anyone know whats gone wrong?

elbekko Posted June 15, 2012 Share Posted June 15, 2012 Were the rockers adjusted properly? Quote Link to comment Share on other sites More sharing options...
Bomag Posted June 15, 2012 Author Share Posted June 15, 2012 No idea tbh. Got a mate over tomorrow who is going to take head off and check head gasket. He will also check timing and reset gaps. Quote Link to comment Share on other sites More sharing options...
Bomag Posted June 21, 2012 Author Share Posted June 21, 2012 Checked the timing last night, and its spot on, so moved onto valve clearance and two were tight when they should've been loose. Reset gaps and runs fine now Quote Link to comment Share on other sites More sharing options...
coachman Posted June 21, 2012 Share Posted June 21, 2012 I was always tought that it is better for the engine to `rattle ` a bit ,then you would know the valves were not tight , not always pleasing to the ear but none the les a good point .coachman Quote Link to comment Share on other sites More sharing options...
elbekko Posted June 21, 2012 Share Posted June 21, 2012 I set mine to the smaller end of the tolerance - just being able to move the feeler gauge. I find that's the smoothest across the range, has no problems revving high, and is not too rattly at idle. Quote Link to comment Share on other sites More sharing options...
