1kz-te oil presure help!!

[COMILUX]

Hey

Just got my 1kz-te up and running in my 93 kzn130 surf.
Oil presure seems to be sitting very low on the gauge - not to far above the L - where do other surf owners gauges sit?

Fitted a oil presure meter and ran motor, started on about 40psi on idle and droped to 20psi once warm, when i give it a rev it goes up to about 65 - 70psi which im guessing is ok?????? Has brand new oil presure sensor so if that presure seems ok maybe gauge is out?

Help please????

Thanks
Nic

pressures are ok i would check the earth to gauge and sender if not that i would say gauge is out of calibration take gauge and sender to e parrots and sons they will calibrate it for ya

[COMILUX]

Thanks, thort 20 may have been i little on the low side but motors stock so dont see why it would be low.
Paranoid as hell running it lol.
Motors quite noisy but think it may be the old fuel in it.

My 1kz idles at 10 psi at about 80 deg once engine is hot and 40 psi at 2500 rpm cruising . Engine has done 170km . Factory gauge is crap IHMO, readings taken off my cheap auto gauge electronic meter , so might be a bit off.
Engine doesn't use oil and makes good power

Thanks for that mate, think ill go buy a after market gauge tomorrow and mount it in there.

can I also ask a question. I have recently change the oil and oil filter. Lately I have notice the oil orange light comes on during start and only goes off when the water temp goes over 50 degrees ( i am running an after market water temp). when i check the oil level in the morning before start up it shows oil is at the Full line. Do i need a new oil level sender?? or is there something wrong with the engine?

engine does have a light drop of oil but not enough to reach the ground..

Mine just has gauge no oil light

Orange light staying on , after engine has started is prob the engine check light, you can short the diagnostic terminal in the engine bay and retrive the fault code.

Do a google search for the check procedure and fualt codes as I don't have the link on hand at the mo.

[Ginzu8]

yeah its an orange light. well i should clarify that my truck is a 1993 land cruiser Prado kzj78 with the 1kz-te motor. the orange light thats next to the oil pressure gauge. I believe it comes on when it sense the oil level is low..


it goes out when the water temp is more than 50 odd degrees and start off for the rest of the trip. or never comes on again as long as the engine is warm

[radar21]

sounds like the oil needs to thin out to switch off light oil might be to thicker viscosity try running a broader spectrum oil may be a
5W40 i no a that penrite do a broad spectrum oil

[Ginzu8]

but the oil that i use this time is only 15W50 fron Penzrite oil

Proceed with caution my oil pressure dropped real low just before it spun a bearing.

[Ginzu8]

tallsam66: did you have the same problem as me before you spun a bearing? I start to think that its just the sensor cause my pressure is pretty good... then again i could be wrong.

[COMILUX]

Put my new gauge in tonight, has good oil presure just factory gauge calibration must have been out

[tallsam66]

Well i noticed the pressure was real low a cpl of minutes before it lost power & wouldnt rev then started knocking.

If you have any doubt id take a look at the oil pump and pickup..... cheap insurance to check it out .... a rebuild isnt a cheap exercise.

[Ginzu8]

yip i agree, any rebuild isnt cheap. but what i want to know is did you have the same symptoms as me. ie. the low light comes on during cold but goes away once the engine is semi warm.. and stay off for good...

Nope.... just noticed low pressure on the guage shorty before death knocking started .

Out of interest what was the cause of the low oil presure?

No idea.... engine builder didnt say.

If you have a look at the engine workshop manual it says that at idle the minimum oil pressure is 4psi. This seams really low but apparently Toyota engines are known for running low oil pressures. This can be a good thing and a bad thing. The good out of it is you don't have a substantial power loss from running a oil pump which from using ones at work requires a lot of push. The bad is you might not get the oil you need when you need it. I would look at taking it to a garage and get them to use a good quality oil pressure gauge if you are worried. Don't get a super crap one. I had one and the oil pressure would drop like crazy when it got warm. I now have a Auto Gauge Smoked Stepper gauge (you can get them on trademe and repco sell different models of the same brand) and the pressure does drop. I am guessing either a faulty sensor or badly made. Also when i turned the lights on the pressure would drop. Explain that

Get something like this, a good quality AUTOMETER mechanical gauge if you want to be dead sure.

Id stay away from cheap electric ones for something like oil pressure.
