I have just put in a oil cooler and filter kit.

But was thinking with everyday driving /hiway driving oil temps will be too cold??

What its normal running temp for oil in a rb25?

I was going to run a oil temp gauge and have a cover over oil cooler for everyday driving then take cover of ect on track or very hot days?

Any ideas or input?

Sorry if it's been covered I did search and google it

Get a sandwich plate with a thermostat in it. That will only open up the oil cooler circuit when the oil gets to operating temperature.

Since you already have a sandwich plate you should get an in-line thermostat. 60deg is too cold. Your water thermostat opens (or should) at eighty something degrees.

I have one of these:

and it opens at 71deg C

Oil doesn't start to beak down until much higher temps than 100°C. No point in having a panic even if the oil is up towards 120°C, which is about the upper limit for sensible operation. Just don't flog it if it's running that hot, and if it keeps going higher than that, then you start to worry, shut it down and wait for it to cool off. 90-105°C is the sweet spot. Anything as low as 60°C is too cold to consider opening the throttle - It's not even warmed up until the oil is hotter than normal coolant temperature.

I doubt that the trip to the oil filter is cooling the oil much. And if you shift the sensor to the sandwich plate look carefully where the port is because if you connect it to the return from the oil filter it won't read any differently. Try a hood over the cooler until you can get a thermostat.

Its cooling too much.

My Greddy thermostat sammich plate opens at around 80 degrees I seem to remember. I have seen 110 degree temps on a squirt through the mountains, perhaps I need a larger cooler before I track it...

^^^^ added to my list of stuff to buy...

i still get normal oil pressure, no excess burning of oil...

so pretty much my set up is cooling the oil far too much... or is it that im not running thin enough oil?

Your oil level could go up because it never gets hot enough to boil off the fuel/water conatmination.

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
