Low oil pressure

[brooksn1]

re : 1987 LAND ROVER LR 90 DEFENDER

When driving the oil pressure is ok but on idle its about 5 to 10 on the gauge - the bottom end sounds ok ? Is this a major cause for concern ?

Many thanks

Dependng on the mileage on your Engine this may be normal... try cleaning out the oil pan or going to a heavier weight oil.

For info, the engine has done 84K...

Then I would pull the oil pan, and clean the pick up tube. Sounds like it may be dirty... with that low of mileage it shouldn't be the pump....

Cool - thanks for all your replies - what oil viscosity is recommened by LR ?

A friend says that it could be the cam/cam bearings that are also worn. Could this also be the case ? How easy are these to change ? I imagine it'd be an expensive job. Is it damaging the engine driving with a low oil pressure problem ?

Cheers, Neil.

I run 10/40 in my Disco, but I plan to switch to maybe a 15/40 when I get over 200k on the clock... I still have a while to go.

I can damage the engine if low oil pressure, but it will make noise first. On startup, do you hear the vavle tappin? If so, clean the oil pan and screen and the pick up tube.... problem should go away.
