just wondering, those with an oil cooler....

after running around in your car for whatever period of time, whats the temp of your oil cooler core like?

is it so hot you can't touch it?

is it cool enough to touch for a little bit?

or is it cool?

i had mine installed a while ago, and i dont think its working. its practically cold after a good 15-20 min drive, and on the track i get temps of around 120-130 degrees...as indicated by my factory gauges.

cheers,

It should get quite warm, especially after a "spirited" drive. Even the oil cooler on the mini gets pretty warm after a short drive. Does your oil cooler setup have a thermostat? If it does, maybe that isn't working properly????

Dunno if the trust kits have a thermostat. HKS kits do, they have an additional return line for when the thermostat is closed.

Pay Anthony a visit, he's got one of each at the moment so you can do a comparison. There's a big difference.

dudes, isnt 120-130 deg. quite high ???

i got a grex oil cooler and the oil temp sensor is off a sandwich plate where the oil filter is. on my gauge i dont think i have ever scene it above 100 deg, even after givin it a bit. mind u i have never been on the track.

hahah thanks tony :)

the grex kit consists of an oil filter relocation kit and core.

the core is sitting in the standard kit position and that is just left of middle behind the grill, in between my front mount core and my a/c condensor.

i didnt install it, it was installed by c&v, removed from one car and then straight onto mine. from the block there is a plate replacing the oil filter. two braided lines run to the oil filter relocation kit. from this plate, where the oil filter sits, 2 lines run to the core.

the core is dead cold, the braided lines from the block are warm. i suspect the problem is lying with the plate where the relocation kit sits. but i'll have to check those lines from the block again! :cheers:

in any case, its going to the workshop thursday morning. i just hope its something simple...

Just thought of something really obvious.

Is the factory sensor reading the oil temp as it is leaving the block, so before it gets pushed through the core.

I only installed an oil temp gauge on the weekend but have noticed that the oil takes a lot longer to heat up than the water. The sensor is reading the temp in the sump which probably has something to do with that, as there is a reasonable amount of oil sitting in there to heat up. Once it is heated up though it stays pretty consistantly around the 90-100 degree mark.

If there is a thermostat in the relocation plate then what you are describing as happening makes sense. Say the thermostat is opening at 100 degrees for example, for every day driving it will almost never direct oil through the core. Then on a track day it's obviously seeing higher temps and going through the core but you are seeing the outgoing temp after it's circulated the block. It's kind of like plumbing a water temp sensor into the top hose of the radiator to see the outgoing water temp from the engine rather than seeing the cooler temp after the radiator.

Frank: your oil temp is reading awefully high dude...mine reads no higher then 95 degrees during normal drives and goes up to 100 when punting it a bit. I've also set warning 110 degrees. My sensor is also reading straight from the oil cooler and not from the oil lines on the block itself. Also what kind of oil are you using?

just to clarify guys, my oil temps are perfect for everyday driving and also for a quick squirt. they only reach 130 when im on the track and after i've done 3 hot laps.

BHDave: i am unsure where the factory sensor is, i'll find that out tomorrow :D i had the impression it was sitting on the block where the oil filter plate is...but im really unsure :)

      Wheel Sizes & Offsets For Skylines

      9" wheels are a little too wide for a RWD 32. They can fit. People have put R33 GTR wheels on 32s for years and years. But they are a very tight squeeze. This has been known for about 30 years. As I said - there is no difference between a 17 and an 18 in terms of what will fit. The rolling diameter needs to stay about the same as stock - not very much larger. If you increase that, you will start to have problems. If you increae rolling diamater at the same time as yo increase width, you will have problems earlier. as 9" wheels are pushing the boundaries already, you would need to be careful with tyre choice. I would put 8.5s on the front of mine, but would expect problems with 9s.

      Diagnostic flow for a code 21 says check signal at the ECU pins, on a voltmeter of some kind it should read 0.1V at idle, 0.12V cranking, 0.15-0.25V at 2000 rpm. Check each coil such that +1, -3 is infinite or very high resistance, -3, +2 should do the same. (-1, +3), (+3, -2), (+1, -2), and (-1, +2) should all be somewhere between 0 ohms and high resistance. If you trace the path from the coil pin all the way back to the ECU in the diagram the resistance you measure at the coil vs connected to the harness should be pretty much the same.

      I have an elite 2500 running an adapter harness on an rb25de neo r34. I took the butterfly out and removed all that junk. But I also went Plus+t at the same time. The butterfly thing works in reverse to the boost solenoid on the Gtt if that makes sense

      yeh they are 235/45/17 up front and 255/40/17 in the rears. I still didn't get my answer if i can fit a 18x9 up front. I want to get 4 of this and see if they will fit before committing as they didn't see an 18x8 as an option but there is a 18x9.5 also.   Enkei RS05-RR 18x9 35mm ET 5x114.3 75.0 Bore Matte Gunmetal Wheel
