Oil filter relocation + oil cooler install
Hi all, I drive on a daily basis a Nissan 1400 ute with a 7agte installed. I saw on my oil temperature gauge high oil temprature 120 c with the temp. probe in the sump. I bought a oil filter relocation kit and a 15 row oil cooler. The lines supplied with the kit are all braided and are an10 fittings and internal measure 10mm. I need to know what would be best with the lines. Shorten them to the required length or do I use the lengths as supplied and maybe suffer oil pressure drop? The lines are nearly double the length I would need to do a tidy install.
Shorten them!
AN8-AN10 works well with 4AGE, but as Jacobxxx already said: Shorten them!
on my previous AE86 i had the trust gready geniune setup kit, and even then oil pressure did drop here and there. make its short as possible to try and limit oil pressure drop/starvation.
dose
I would be looking into other causes instead of masking the issue.
Running an oil cooler on a daily is not required IMO. Especially in winter!
Oil temp in normal operating conditions will roughly mirror your water temp.
Just more docile with its variation.
How's your oil pressure and water temps?
My engine is brand new also the oil pump is new so cold pressure is 5 bar but as the oil get hot it drops down to 2.8 bar, water temperature stay at a constant 80 celcuis, my cooling system is quite big, total capacity is 9.8 liter. The sump is baffled with trap style doors similar to what I saw in previous posts either on this site or on the toyospeed forum.
What the.. I`m getting between 6-7 bars on completely stock, newly oil flushed JDM engine w/ short filter bolt and filter mounted directly on the block..
Whats up with people getting so low oil pressure nowadays?? 2,5 bars is terrible and will kill your engine way faster than a presumed 120 celcius water temp!
You want 5,5 bars, ideally 6!
Not true.
Eg Sr20 FSM states :
Cold idle - 5.5 bar
Idle warm - 0.8 bar
@3200rpm : 3-4 bar
My rebuilt sr was spot on those numbers with same OEM spec oil viscosity.
Excessive oil pressure is also bad, you can blow out seals at minimum.
Also it should be noted that the oil pressure is determined by the viscosity of the oil.
And FSM figure are with factory spec oil.
Yeah, you generally want about a bar at idle with the oil and coolant up to temp.
One thing Joel missed is:
a guy on another forum was saying his oil temps were at 60 when coolant temp is up to operating. That is gonna accelerate wear and cause unnecesssarily high oil pressure.
Also, 120 is on the edge of alright. If it hit that every now and then while doings laps on the track, I would probably leave it. If it were approaching and holding closer to 130 then that's definitely oil cooler territory.

Thanks ken for adding that, I was more getting at the specified viscosity on the bottle for normal operating temps will affect your pressure reading .
You are however more correct
Regarding the temps, 120 'C on a daily is way to hight IMO
On the track after about 4 sold laps I'd expect to start seeing numbers over 100'c. But on a daily driver? Just seems like something is not right.
