I wasnt actually moaning about anything i dont like forums full of geeks but it just seems that someone with an innocent question is shot down straight away. maybe they have looked for the answer elsewhere but have not found it. as you said a forum is all about sharing advice.
I actually think this is the best land rover forum on the net and only bother with this one.
mainly because its not all part numbers and special tools!
I have realised that this is the way the forum works and accept that. I was not complaining or suggesting we change our ways at all, i was merely expressing what i see.
Now we can all get on. (until the nex time!)
 
Hi, Come all you experts whats wrong with this dead lump, and how much shall i offer him? I am ok with spanners and Haynes manual but im no expert on engines. Colin
 
the engine was rebuilt over 2 years ago and had given me completley trouble free motoring for 15k miles, until the pressure issue. Since then it has been striped and rebuilt again in the last 8 weeks to try and sort the oil pressure issue. Before you go down the oil pump route it has been changed. The only reason it is up for grabs is because every component, and i mean every component has been replaced for a new one. thats all the shells. front cover, oil pump, camshaft bearings, camshaft, heads skimmed. all off these components have been run for a hour tops. the only part which is as per the build 2 years ago is the block, rods, pistons and crank. The rods and pistons were new at the time of the build in 2007. At the time the block and crank had the works at the machinists.

If I new what was up with the thing i would get on and sort it as I have a current project on the go which is in need of a lump.
 
forgive me, if this sounds stupid, but how did you test the oil pressure?"the oil pressure is around 34 - 55psi and slowly drops off at tick-over"could there be a slight leak in the tube to gauge?

I'm sorry maybe I'm a cynical old Coont but the more you add to this thread the more My suspicious mind goes Yeah right!! Like ****!
 
i have always been told that the v8 rover engine has always had low oil pressure(about 10psi at tickover)and that the only thing to worry about, is if it does not raise quickly as soon as you rev.
 
i remember readin sumwheres that occasionally the oil warning light may flicker at tickover and is nothing to be alarmed about


found the fooker,it s stated in the early discovery owners handbook

Let's look at the lubrication system-it comprises basically of a tank (The sump), a pump, filter and a pressure relief valve. The pressurised oil passes through galleries including the crank. Bearing clearances and crank endfloat are critical, more so with the V8 crank as there are so many oil holes. If the clearances are too great, the oil flow will be less restricted and most of the flow will take the least path of resistance and spill back in to the sump. This is not as critical at higher engine speeds as the pump delivery-provided that the condition is good-is well able to deliver the required volume to the engine. The problem arises at idle speed, especially when the oil is warm and thinner which in turn spills back at an even higher rate, the pump delivery at idle is lower anyway and the oil pressure will drop considerably, especially when hot. This is mentioned in several handbooks, the Rover P6 (V8) and Classic which state that the warning light may come on or flicker at idle when warm but should go out immediately the engine speed increases. I had a P6 with a pressure gauge which showed an idle pressure of 5psi when warm and 40psi when cold yet the moent the speed increased it would fly up to 50psi. If the bearings and crank were replaced and all clearances, crank end float (Thrusts) were checked and in spec.,Oil pump was in spec. regarding clearances etc., no leaking gaskets and the relief valve working correctly I can't see why everything should not be o.k.

Unless of course someone knows different!!!!!!!:blabla::blabla::blabla::blabla::blabla:
