oil light

[Seanz]

hi guys, 2007 3ltr GU after hard acceleration oil light appears pulled over checked oil level, good motor not hot.
dropped oil pan thought it may of been dirty pick up nothing engine has 160k's oil changed 5000ks any ideas about this Am about to install oil pressure gauge only thing to keep mind at ease about oil level

Hi mate could be your oil pump cavitating under hi rpm what oil do you use?? try the pressure gauge 1st & seeif it improves

My Mechanic says its a GU thing , mine does it all they time but not lately
All I do is stop turn it all off and start again,

Is yours a common rail? There was a few cases where the oil pump bolts weren't torqued correctly and worked loose in the early common rail engines.

With a 160,000Ks on the clock I doubt if this will be your problem. It would still be a good idea to check while the sump is off.

Common rail 03/2007 auto I run 10w 40 tried 5w still
did same thing even traveling light not towing the boat thanks.

Cheers,
I run 10w 40 and have run 5w same thing happened
told by Nissan high oil sender faulty which 1 told there's 2
so thought gauge was best options

I'm a big fan of guages, hate this light comes on your stuffed. I like to monitor how the motor is performing ,
Plus I can drive accordingly. Other than the Pillar pod there is not many places for other guages like water temp, oil and AT temps and pressure
maybe another dual on top of steering housing

Oil light is a concern do you have pressure gauge setup
and if so is it from top sender above starter motor.
thanks again.

Two oil pressure switches on ZD30, one above starter motor is the high pressure switch and one under turbo charger is low pressure unit. Easy to troubleshoot since only single wire is involved the switches break earth when engine is running (and obviously there is oil pressure) Most would put a T for additional gauge on the low side due to having more room/space. There is no room above starter motor and other way to do it would be to run a hose to remotely mounted sender which might be a bit risky.

Cheers

thanks Rumcajs, so passenger side is the low oil pressure side I take it either will do as a pick up for a gauge for pressure T section.
Will let you know the out come, has to be better knowing you have oil pressure

Cheers
