Hi gang,
Being a born again DIY mechanic I am tackling things beyond the normal servicing requirements for both cars, boat, etc. I think it is character building when those bloody computers and all things electrical get so complicated. The current assignment thrust upon me is courtesy of the dunnydore which is trying to drive me insane and not to work. Having solved a couple of computer problem I now have the oil light coming on intermittently. The oil level is OK and I thought that it only leaves a couple of options like the wiring, pressure switch or the pump. My wife drove it to work this morning and it was ok until she stopped at a red light when it came on - puting it in
park made it go off, so I was thinking that maybe the idle speed when in gear maybe to low. Any contribution is appreciated.
Kind regards

Just to be on the same side, get the oil pressure checked with an independant gauge. It could be a an oil pressure problem.

Thanks emo. Is it possible to do this without getting professionals involved? In my boy racer days I can remember (vaguely) having to fit another prssure sender to make that happen.
Kind regards

Yes, it's pretty easy but you need an oil pressure gauge. You unscrew the oil sensor and screw in the gauge. 5 min job.

Hi.
Do you have the correct oil and filter fitted?
Get your self a good quality test gauge and test line,
Get a test line that is long enough to either get the gauge inside the car or tape it to your wipers.
Check the pressure on a cold engineat idle and at say 1500 rpm, then take the car for a run checking the pressure as you go.
When the engine is up to full operating temperature check the pressure again at idle and 1500 rpm
This will give you some ideas

Hi Ray,
I reckon so, but I did change to a fully synthetic 10,000K ago (due for another change now). Niggling me that the higher viscosity might be doing this. When you say a guage is this something I would get at a tool
shop (heaven forbid I need more tools) and does it connect up to the existing sender? (I know this doesn't make much sense because if the sender is stuffed then so will it give bad readings).
Kind regards

goodday beatit
sounds like a dicky oil pressure swicth to me .have you recently serviced the car is there oil in the oil filter
people hang bleep e on me but i always like to put a bit of oil in the filter before screwing it back on to give the suction threw the filter something to work on
when my dad was alive he had his toyota crown serviced but the oil light would come on at idle and when i checked the filter it was bone dry i also believe 1 of my filters took about 5000ks to pull oil thru it while we were away it was serviced just before we left and when checking oil 1 day it was down about 3/4 of a litre only time it has used oil topped it up kept a good watch on it but was ok seemed to be the only answer

Hi Steve,
Not sure if there is such a thing as a dumb electrician, the game would soon eliminate those out of the gene pool I reckon. The vehicle has done 210,000K and whilst no spring chicken it seems just fine - so I'm thinking that the pressure itself should be OK. The oil and filter have been in the car for 10,000K but I have been experiencing some weird car stuff with the computer recently so anything is possible. A bit hard to fill up the filter on this vehicle as it is mounted horizontally. I just priced a new sender and at $22-80 I will be replacing it in the next couple of days.
Thanks and kind regards
Theo

Hi there Beatit, what model condom is it, 96 upwards with eco-tec motor if so dump the synthetic oil out of it, it stuffs the roller rockers big time, we have vx01 supercharged s pack with ecotec, was informed after I put the synthetic and tappets become increasingly rattly an took to holden and was informed not to use fully synthetic in the v6 ecotec engines.So I did and still has a rattle every now and then but has since new so dont worry about it now and wife just drives it.Funny thing is HSV only recomend full synthetic and you guessed it run the same roller rockers minus a few valves and tappets go figger. Only got 60k on it now was getting rid of it last month but decided to keep it, still like new.I think if you get it reguarly serviced then it wont be oil pump but as said above more likely to be oil pressure switch. I've never had to fill up filter prior to screwing new one on and as you said cant be done anyway as it on its side.I doubt idling speed, should be on around the 850 mark and should idle back up if air is switched on, does it hold its revs up when air is on ??? if not then yes maybe idling to low but I doubt thats your problem. Hope this might give you some more thoughts. Regards Steve M

Hi Steve,
It is a VS V8, so not an ecotec motor. I got to admit it has sounded a lot more tappety (a newly invented word) just like when the oil is running low. So maybe move away from the synthetic oil. Will check the aircon thing. But seeing it is due for a change I'll go back to a standard oil.
Funny thing is that it only started late last week and the synthetic oild has been in it for 10,000K but it was pouring rain and I have had some other computer issues (fault 82 - 1-2 shift solenoid) so there were some circumstances that might have created this problem other than the oil itself.
Kind regards

Hi there Theo, didnt think of V8, we had the V8 in our series 2 97 Statesman and I used the full synthetic in that so would disregard my comment on the oil thought it was ecotec.Our stato went a bleep load harder with the synthetic in it that motor loved it. Sound like a revhead dont I but I use to love giving that a squirt every now and then my wife misses it big time hates the commodore she reckons the pistons are gunna come out the top one day when she gives it some. Might be quicker to take to holden and find out what the codes are save you some time.Just read your reply again we use to get a code some thing like that and it was to do with the transmission and after stopping at lights it would actually start off in second gear instead of first, use to have to turn it off restart and it would be ok again for a while, probably did it half a dozen time in the last 6 months never got it fixed as I knew we were trading it in.

Hi .
Test gauges of good quality are mechanical ( unless it is the expensive electronic type ) . The sender unit is removed and the hose for the qauge is fitted to this port.
Some auto electrical shops will have equipment to test your sender switch.

Hi Willem,
Not a bad idea except these bloody cars have computers and they seem to be on to those sort of tactics. I would drive around with it on except that I fear most an error message leading to the car going to limp mode or worse stopping for no other reason than a bad sender/connection. Give me a non computer job any day but that is getting less and less these days. I'm pretty sure that the reason for these computers is purely to ensure that you have to go back to the dealership for servicing and repairs - I know just another conspiracy.
Kind regards
Theo
