hi guys,i just changed the rocker gasket on my 2ltr omega gls,went 5 miles and the oil warning light came on. can anyone please tell me if this is a new problem or did i do something wrong, the oil levels fine.cheers.

Have you done anything else?

The reason I ask is because the oil level sensor is on the sump and you wouldn't have touched it for a rocker cover gasket.

Have you done an oil change recently? If so check your filter is installed correctly and the wiring to the sensor hasn't been disturbed.

did,nt do oil change,iv,e taken the rocker cover back off and started the motor up and theres a slight   spray of oil at the rockers but not much.do you know how much there should be?

If there isn't enough, the cams will run dry. Thats when you know there isn't enough. Can't remember what the 2.0L looks like with the covers off.

There are normally bolts with holes in that act as jets.

Which oil warning is it? The pressure (oil can red light) or the MID (Check Oil Level).

Did you use silicon to seal the gasket? Wondering if some silicon has got somewhere it shouldn't.

[wrecker]

yes its the oil pressure light,i did use silicon but not much.the rocker cover is held on by 10 allen bolts and on the inside there is 10 o rings,the bolts go into the upper cam carriers so i wondered if the carriers were also oilways and if the bolts were over tightened would they block them off,what do you think?

[Kevin Wood]

The only lubrication to the cams is from oil which returns from the cam bearing journals and from the hydraulic tappet bores. There aren't any jets specifically to lubricate the cam lobes on this engine.

Sounds to me like there is a blockage somewhere.

I wouldn't use it or drive it until you have at least checked the pick up pipe and sump.

How old is the oil and filter? It could just be age and it's due.

i changed the gasket because the sparkplug wells were full of oil and did a test run without topping the oil up untill the oil warning light came on,when i topped it up could i have created an air lock?

[wrecker]

sems strange it happened right then though but i better take  the sump off

I can't imagine an air lock as the oil pump would push the air out.

The oil pressure sensor should be around the crankshaft pulley. Take a look and make sure the wiring is ok.

Is the pressure light flickering or on constant?

[wrecker]

yeah the air lock thing was clutching at straws,the oil light is constant

[Kevin Wood]

Is there actually any evidence that the oil pressure is low? Are the tappets and bearing quiet? If it's survived being driven any distance with the light on the likelihood is that it's the pressure switch.

Kevin

bearings are quiet,tappets slightly noisy but got no louder when being driven in fact after the initial rattle i topped the oil up and it got slightly quieter,do you know how much oil should be at the rockers,ie,just a film or pools of it?
