mmgemini Posted December 15, 2012 Share Posted December 15, 2012 Yes Mo I did..... I wonder if it's just shattered or the fingers have worn off and knackered the crank...... Quote Link to comment Share on other sites More sharing options...

mmgemini Posted December 15, 2012 Share Posted December 15, 2012 That to me reads "Oil pump pressure relief valve" not the actual oil pump. If indeed an oil pump has been fitted the you" Ralph " must be right with the cam bearing. There's not a lot more to loose oil pressure with. I hope he fitted a new timing belt kit when he did the pump. Quote Link to comment Share on other sites More sharing options...
western Posted December 15, 2012 Share Posted December 15, 2012 there's a comma between oil pump & pressure relief valve Quote Link to comment Share on other sites More sharing options...
mmgemini Posted December 15, 2012 Share Posted December 15, 2012 Well there's only the camshaft left now..... I wonder did he feed the fingers of the oil pump gear over the nose of the crank correctly. Was the nose of the crank rounded ? Also did the "O" ring on the pick-up pipe get replaced. What happens if the oil filter is taken off and the engine spun over with the stop valve disconnected ? Oil should fly ot. Quote Link to comment Share on other sites More sharing options...
Mutz Posted December 16, 2012 Share Posted December 16, 2012 Has he used a gauge yet!!! Quote Link to comment Share on other sites More sharing options...
mmgemini Posted December 17, 2012 Share Posted December 17, 2012 Has he used a gauge yet!!! Doesn't need a gauge. There's no oil getting to the oil filter http://forums.lr4x4.com/index.php?showtopic=80321 Quote Link to comment Share on other sites More sharing options...
farmer_ben Posted December 17, 2012 Author Share Posted December 17, 2012 ive took the filter off and spun it over ,nothing happens ,the crank was fine and i turned the pump so it just slotted on and yes i fitted a new seal on the pick up pipe Quote Link to comment Share on other sites More sharing options...

mmgemini Posted December 18, 2012 Share Posted December 18, 2012 My pump was new but the crank nose was damaged....What was the old pump like ?? All fingers intact ? Quote Link to comment Share on other sites More sharing options...
farmer_ben Posted December 21, 2012 Author Share Posted December 21, 2012 the old pump was fine couldnt see anything wrong :-S Quote Link to comment Share on other sites More sharing options...
western Posted December 21, 2012 Share Posted December 21, 2012 does the crank front end rotate when you spin the engine over ? if not crank may be sheared.therefore it cannot drive the oil pump = no oil pressure or oil flow. Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted December 21, 2012 Share Posted December 21, 2012 Possibly a daft suggestion this. I was told by a man who did a lot of Range Rover repairs that RV8's used to require the oil pump gears to be primed with petroleum jelly so that when starting the engine for the 1st time they would suck up the oil from the sump, would this also apply to a 300Tdi?

No, refer to my earler reply to this 'priming' suggestion, LR workshop manual just says fit new pump & start engine. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted December 21, 2012 Share Posted December 21, 2012 I did fill my oil pump with engine oil as best possible. Pressure came up straight away. Quote Link to comment Share on other sites More sharing options...
farmer_ben Posted December 21, 2012 Author Share Posted December 21, 2012 tthe crank is turning ,ive put another engine in tonite but cant get it running :-( Quote Link to comment Share on other sites More sharing options...
TSD Posted December 22, 2012 Share Posted December 22, 2012 Bit late now, if you changed the engine, but when you had the sump off did you check the oil pickup pipe isn't cracked or broken? Just thinking an air leak above the oil level would prevent it from ever priming itself. Quote Link to comment Share on other sites More sharing options...
bushwhacker Posted April 23, 2013 Share Posted April 23, 2013 Hello. Anyone know at what pressure a gauge would read at tick over and at running speed on a 300tdi. A mate has fitted a new rad/oilcool and he is getting low readings after installation. He did have good pressure as he called before the new parts. All the pointers from the thread will be gone over to night. Thanks Quote Link to comment Share on other sites More sharing options...
ejparrott Posted April 24, 2013 Share Posted April 24, 2013 Not sure about the 300, but IIRC the book says 55psi cold and 25psi hot for the 200 Quote Link to comment Share on other sites More sharing options...
western Posted April 24, 2013 Share Posted April 24, 2013 Not sure about the 300, but IIRC the book says 55psi cold and 25psi hot for the 200 for a 300tdi engine my rave cd says 25 to 55psi [1.76 to 3.87 kgf/cm2] engine warm at normal operating speeds Quote Link to comment Share on other sites More sharing options...
ejparrott Posted April 24, 2013 Share Posted April 24, 2013 Just checked my disco manual now I'm at home....25 to 55 at normal operating temp...must have imagined the cold bit Quote Link to comment Share on other sites More sharing options...
Boydie Posted April 25, 2013 Share Posted April 25, 2013 The spring and the washers look as if they belong to the oil temperature valve assembly. Quote Link to comment Share on other sites More sharing options...
