just noticed my oil temp is around the half way mark for the past couple of days as per the centre gauge

wed night i noticed the radiator collant was boiling too? i checked the coolant level today and radiator had to be filled a little to top it up but the reserve was ok

checked engine oil level this morning and thats fine

engine temp is sitting half way as per normal

oil temp doesnt really go past 1/2 way

what could be causing this?

cheers

Sounds normal to me.

I'm not so sure about that.

My GTR and many of the other ones I test drove before buying my one doesn't get anywhere near half way on the oil temperature gauge under normal driving conditions.

Around town, mine is around 80 degrees or so. Hard to tell where that is exactly, but the gauge is still hovering over the numbers "70"... so basically about 1/6th of the way up the gauge from the bottom.

Driving on the highway at 110, it tends to go up to 90 degrees or so. still below halfway. Apparently (yet to see this), but on track use, it should get around half way up the gauge or perhaps more (??). When was the last time you changed your oil, oil filter and stuff?

What about oil pressure? Should never go below 2 or above 6-7 in my experience...

Also, how did you know your coolant was boiling?

It can depend on many things. How hot it is outside, how hard your driving, if you have an oil cooler etc...

Daily driving i get around 80-90... on hot hot days even 95-100...

Around the track i've had it up to 130..... which is where i start to ease off.....

no oil cooler and the half way mark of oil temp is just from normal driving (no boost) after about 40mins worth of driving...

oil change (motul chrono 10w40) about 1500klms ago.

as for the boiling coolant, you can actually hear it before it starts flowing through the reserve and leaks out eventually!

got it booked it at Advan on monday to try and figure it out.....hoping its thermostat or blocked radiator or something simple.....doing a cylinder leak test so we'll see what that brings up :?

could it be a stuffed cat converter?

would dying turbos cause this?

Ive had boiling coolant before in my GTR when i first got it and the cause was a radiator that was block to about 80%, i got a new 2 core radiator and new thermostat and it solved it straight away. My oil temp sits at about 80 and 90 odd when driving for a longer period of time.

2 weeks pass since the visit at Advan

the radiator starts leaking....so I baby the thing to the workshop (not the same workshop as mentioned above, never again!)

turns out the radiator is blocked (apart from the obvious leak that just started)

ended up buying a new radiator from Justjap, change thermostat (old one was OK), changed clutch fan just because and i couldnt get a refund anyways (old one was also in great condition)

Now, my water temp is always below 1/2 way, oil temp just gets above the 70 mark on the gauge even with a bit of spirited driving and aircon on!!!!

Moral of the story, dont think a well known tuner can solve all of your problem! Had a feeling that the radiator was stuffed but decided to listen to the mechanics!

But what can you do, it is a GTR and I'd rather spend a few $ for someone in the know to figure things out rather than spending thousands to fix the engine!

      My extinguisher mounted like this unscrewed a little (Maybe from the chair sliding forward) and dumped a bit of white on my mats. I'll need to get a more narrow one for future.

      I totally couldn't do the whole kids taking up my life thing! 😮 I find it bad enough doing 45 hours in 4 days, and then fitting normal adulting life into the other 3 with no kids! As for my mates race cars, they're AMG C63 setup for production racing. The original is what has just been stripped and a brand new shell built. The original is then going away to have some panels straightened, then it will be put back together again. Then there's a third that will shortly head off to have a roll cage put in, then build it up too. And potentially a fourth to be built too... Oh, and he has two Renault Clio D class production cars, ha ha. And when he's not racing them in the Australians and QLD production championships, he's been racing one of Chaz Mostert's Lamborghini's in GT4. They just won GT4 at the 12 hour in the Lambo. We're pushing to finish the new AMG as it has its first round (and potentially its first shakedown/outing) in under w weeks for Round one of QPC, and that round is really the shakedown to make sure it's all good for the Bathurst 6 hour, which I'll be at too. Ha ha ha Working on my project is different to his, I slowly tinker and work ways to make things happen on a shoe string budget. Hes in a good position that he has a massive workshop full of parts and tools, ha ha. He also looks after me. When his air compressor died, he just needed it working, so bought himself a new one and gave the old to me. Sand blaster unit too, and a 20t pressing. And pretty much all the shelving in my shed too as he upgraded all of his (the stuff he gave me is the expensive black Bunnings heavy duty stuff)!   I enjoy working on his stuff. No decision paralysis, and anything that's needed parts wise is just there. Plus, then I get to be hands on at the track in real racing, not just club day stuff.

      I definitely agree with you there - I never click on content for cars I would never ever be able to get or compete with/against/be seen next to. Seeing a MX5 compete with a FD RX7 will make people upset though, for sure. Even in 2.5L Turbo form which is pretty grass roots. (or at least as grass roots as classic cars can be) Yes we're all classic car owners now.
