davidlandy Posted January 24, 2007 Share Posted January 24, 2007 My bro in laws 200 tdi just wont run it all started happening after a run to London - on the way back it began to misfire slightly and run rough. It had also pushed oil into the air inlet via the breather. when he got it home he switched it off and it has never started again. checked valve clearances - these were massivley out so adjusted back to what to they should be - still no start fuel soleniod checked ok heater plugs knackered - replaced still no start due to a trace of oil in the water suspected head gasket - new one fitted - still no start timing check ok what next ? any ideas? or should we be goin back over any of the above like the timing many thanks Quote Link to comment Share on other sites More sharing options...
JST Posted January 24, 2007 Share Posted January 24, 2007 fuel supply? in that is there any coming out of the filter to the injectors? I must make a note - dont go to London! Quote Link to comment Share on other sites More sharing options...
Ex Member Posted January 24, 2007 Share Posted January 24, 2007 Have you checked for fuel at an injector? Pull an injector line and see if fuel comes out when you crank. This is where you should have started. Quote Link to comment Share on other sites More sharing options...
davidlandy Posted January 24, 2007 Author Share Posted January 24, 2007 yep theres fuel at the injectors it turns over ok but all you can hear is like one feeble attempt to fire during the firing cycle Quote Link to comment Share on other sites More sharing options...
SiWhite Posted January 24, 2007 Share Posted January 24, 2007 Diesels don't need many things to be right to run. I would check (in this order); 1. Air getting into the cylinders (pull hose from manifold and check valves working) 2. Check fuel getting into cylinders (pull injector, point it in a safe direction and try a quick crank (PPE worn by all)) 3. Confirm timing correct - hand crank the engine with glow plugs out and see if valves open and shut in correct correlation to engine's 'huff' through the glow plug holes 4. Get injectors tested 5. Do a compression test Let us know how he gets on! Quote Link to comment Share on other sites More sharing options...
davidlandy Posted January 24, 2007 Author Share Posted January 24, 2007 Simon cheers for that - as regards compression how much should we looking for? Quote Link to comment Share on other sites More sharing options...

western Posted January 24, 2007 Share Posted January 24, 2007 Simoncheers for that - as regards compression how much should we looking for? no laid down figures in workshop manual [genuine] just a difference of around 70psi between each cylinder.

pigster Posted January 25, 2007 Share Posted January 25, 2007 my figure before redoing hte head completely... were pot 1 - 305 (radiator) pot 2 - 400 pot 3 - 310 pot 4 - 400 (bulkhead) they should all be approx the same,,, so around the 400 mark - I can not remember if that was psi though. but I would go with timing being out... I assume you have aligned the flywheel and the injector all correctly.. and also the dot mark on the crank.. (just asking) my one was a bugger to start when it was out by about 2/3 teeth but she did eventually and ran rather well too.. no laid down figures in workshop manual [genuine] just a difference of around 70psi between each cylinder.

davidlandy Posted January 26, 2007 Author Share Posted January 26, 2007 well guys the compressions are as low as 100 on no.3 2 others are 120,130 and the other at 210+ (could read any higher cos its a petrol compression tester!!) Decided to drag it around the block to start it - well it did, smoke all shades of the rainbow, it was like a red arrows display! Oil pushed out of the filler cap and breather, and the oil light is now flicker when the engine is on idle. so I need to either do a bottom end rebuild or find a 200tdi bottom end thats going surplus ! any ideas?
