Oil light still comes on after replacing oil pressure sending unit.

I have a 1998 ford escort and already had a bunch of things fixed on it.

Recently the oil light has been coming on but not staying on. It kind of flickers on for a few seconds then goes off. The oil pressure sending unit was leaking so I had that replaced yesterday and figured that took care of the problem.

Tonight the oil light came on again but went right off a couple seconds later.

I heard that it could be the oil pump itself going bad which I hope isn't the case , but are those the only 2 things making the oil light come on?. The oil pump, or oil pressure sending unit?.

If it is the oil pump what would the average cost be to have a mechanic replace it?.


By the way the oil is full and it was changed about 1,000 miles ago.

Did you change the filter when oil changed ?

Depending on mileage , it could be general wear and tear on the engine with bearings etc. that is allowing oil pressure to drop .You could check actual oil pressure with a master gauge to verify . Could even be the oil pump pick up screen partially blocked .

p.s . you dont say what engine fitted .

Sorry forgot to mention it is the 2.0 and just a couple days ago I started hearing the rockers? Under the valve cover starting to tick. Maybe because oil not getting to them?

The head was completely rebuild about 1,000 miles ago if that makes a diffference .

The car has 174,000 miles and I am hoping it will make it to 250,000.

You can get a repair guide with walkthrough at Autozone if you want to drop the sump / replace oil pump .
