Oil warning light flickering on tickover

Last week the oil warning light started flickering on tickover as I had got home from work, 5 miles, so the engine was warm.

I changed the oil and filter and everything looked OK.

We have been to the Lakes this W/E no problems, checked the oil and water when we got home last night and things seem OK. The oil was down a bit to the full mark but I had over filled it a bit so I wasn't over worried.

Got to work this morning and the flickering was back. The light goes out immediately when I rev it.

What could be up?

What do I check in what order?

My thoughts were to check the oil pressure to be sure the sender is working, are gages dear or can I borrow one (Mirfield)?

Bob.

Hi, if you have good oil presure at cold start up and as soon as oil warms it looses presure there is a clearence issue, take a oil presure reading @ tick over cold and tick over hot !!

change your oil pressure switch,
did exactly the same on my disco after a run

changed switch no further problems
