Hi,

Am new to yor fgeorum but wondered if any here could assist in solving a current problem.
I have just done an oil service on my calibra 2.0 eco and now suddenly l have no oil pressure after a couple of minutes. lf l switch the engine off and restart the pressure goes right up and then sinks to nothing and the pressure light comes on.
Prior to the oil change there was not a problem with the pressure.
Hope you can assist
Thanks
Dom

worst case is f.u.b.a.r.'d oil pump ...

best case is dodgy sender - find the connections and clean them up, check wiring for condition etc from the block all the way to the back of the dial.

next check would be the wiring on the dial itself ...

if still persistent after that (and actually most likely since the oil light itself is also coming on) ... the pressure sender unit itself could be the culprit ... swap it out.

even before all that, have you rechecked the oil level since doing the service?

Thanks for your quick reply James,
Will check out what you suggest, as soon as it stops raining!! Will ho pefully be a regular on the forum, work permitting.
Have checked the oil level and is still fine.
What was worrying though, was a post on Calibra owners club which said that it could be the wrong oil filter, or a blocked sump filter. The other suggestion was that the pump had gone, and reading in the Haynes Manual the trauma involved in changing the pump. Strange thing was the fact that before the oil change, with the dirty oil the pressure was fine.

It is possible if the old oil was really bad, that in draining it you have dislodged a piece of [email protected], which as blocked the oil pickup?
