As long as it goes out and stays out, it should be OK. It should say in the owners handbook it's acceptable for the oil light to flicker at idle on a high mileage engine, does this happen?

It may be fitted with the wrong oil filter allowing oil to drain back into sump when parked, this has to then be filled when started (2-3secs!).

doesn't flicker at idle, just when fired up. Car's 'only' done 51k.

Don't use Halfords filters (made by Wipac). The anti-drain valve does not seat properly as the material relaxes after exposure to hot oil. Best filters are Mann & Hummel or Fram. I spent a long and messy time at Lucas sectioning used filters, and contrary to some opinions on this site, I found many were poor. The Lucas (Crossland) filter had swarf in the thread!

How long ago was your work done? See the thread below which contains a a reply from Halfords on source of their own lable filters.

Might be worth while either replacing, or cleaning the oil pressure switch in case it's got some crud in the end of it.
|
|
You really need to measure the oil pressure at start up and at 3000 rpm or so. This should either identify a problem, filter, Pressure sensor, or put your mind at rest. Regards Peter

Sorry forgot, How quickly does the light come back on when you turn it off. ??? You can test the switch, when removed with regulated compressed air if you have access to same. Peter
|
Doesn't take long (1/2 Hour?) for the light to come on again when restarting. Does anyone know where the pressure switch is? Haynes manual for 80-90 useless. Orion manual for 80-90 useless. Haynes 75-80 manual tells us where the switch is for the old OHV engine, but they've moved it since then :-(.

Whay do you mean 1/2 and hour. If that is the case you have a damaged switch that is slow to open the contact 2 to 3 secs and 1/2 an hour to close again. Explain please you may have found your problem. Usuall ythe oil light hase come back on within a second or two after the engine has stopped and you have got the ignition back on. Regards Peter
|
oh, I meant it takes 1/2 hour after stopping the engine for the 2-3 second fault to re-appear (at a guess), i.e. the light not going off straight away.
Sorry should\'ve understood your question right. Light comes on after stopping engine almost instantaneously.
|
I don't think there's any problem, as long as the light goes out and stays out within 5 seconds of startup. I used to own an Escort with the 1.3 HCS engine (carb) and it did precisely the same thing, from 60K up until well over 100K miles.
Not sure about the merits of semi-synth in such an old-tech engine, but my experience suggests that with regular oil changes, and long journeys, these units rattle on for a long time.

Hi
The only reason these hcs engines rattle is cause of the rocker assy (complete sys not just tappets)
some hcs escorts and fiestas sound like singer sewing machines at idle and at speed
I own a hcs fiesta so iam laughing at myself
