oil pressure light

[blingsta]

me again! what does it mean when oil pressure light comes on at low revs or on idle?? does it mean that oil isnt circulating? and how much damage can this cause?

[Steviec]

Sounds familiar! Mines the same, is yours smoking?

[Brianmoooore]

Oil light on is not normally good news, but try a new switch before you panic too much.

[blingsta]

mine started smoking and running very badly on way home last night together with overheating and head gasket!!!

[Brianmoooore]

Just keep the oil pressure switch and fit a new engine to it.

Just keep the oil pressure switch and fit a new engine to it.

[blingsta]

so seriously.. does block need to be changed now, or can it be saved?

[Brianmoooore]

It can be saved if you throw enough time and money at it, but oil pressure light on, overheating, smoking, bad running......
I haven't seen it, so I can't say from here, but sometimes you've just got to know when to give up!

[blingsta]

that is a very good point Brian, but i thought it would be something simple such as oil not flowing properly due to the bad running? and once the engine is flushed with engine flush together with the cooling system it should solve problem!! Ive had the head off and inspected it thoroughly, No signs of head gasket failure or cracks on head..???

[Chris-W]

Have you had the cam out of the head?

[blingsta]

NO, but ive inspected as closely as i can, and no cracks under the cam...

[Brianmoooore]

You won't see them on the rough cast metal - 0nly as a faint grey line across a cam journal.

[Chris-W]

They like to hide underneath the cam, there's no way you'll spot them in a fully built head.

[Brianmoooore]

Beat ya to it!

[Chris-W]

Can't type as quick, clearly. Plus I was distracted. And the cat ate my keyboard.

[blingsta]

cheers guys...i find it easy enough to change the head gasket, but i dont know how to take the cam off, any tips for me? is it easy, and i take it tappets will need re-adjusting when put back together?
