Oil Cooler whine?

By thermocouple im sure that you mean the mocal sandwich plate adapter correct? Nissan said 168 isn't bad, but again it depends on what oil you are running. I have the same whine coming out from my car and I've done endless researching on this subject. Z1 said that it is "somewhat normal" in one of their other threads. HOWEVER, I have also read that it has to do with the oil lines rubbing on the chassis giving off a resonating frequency. I am going to Nissan today to have them wrap it to see if it makes a difference. The tech there that installed is a gt-r certified mechanic and also worked at a speed shop here in cali so i know he'll hook it up

Which dealer is that? I see your in riverside so really close to me. Actually I go to the riverside dealership (performance nissan).

Funny enough they said one other guy was waiting for the oil cooler too (I was waiting longer at 3+ months). Is it the same dealership? LOL.

I did talk to the guys there and they said that they couldn't wrap the lines to get rid of the noise as it would void the warranty or some crap. =( That was a bit lame but the sound doesn't bug me THAT much so I will live.

It is not difficult to wrap them yourself. When I installed my oil cooler, I bought about 4 feet of heater hose that has the same ID as the oil cooler lines' OD. I slit the hose length-wise and cut it into sections. I wrapped and zip tied the hose pieces everywhere the oil cooler lines touched anything -- maybe 3 places total.

I did not do it to elimiate noises, but to prevent any chafing of the lines against other parts.

Food for thought.

I've seen a couple of threads on oil coolers causing whining noises, the car whines a lot without one. Even after you turn the car off with the clutch in it whines, and then you let the clutch out and it stops. I had the hood off of the car for repainting and it was really noticeable, this was just before I installed an oil cooler (Z1) this week, no change in sound afterwards. YMMV but I think it's the way it is.

I go to Raceway Nissan. So did the wrapping cure your problem with the whineing sound as far as the wrap that you used? I took it to them today and it got rid of about 20% of the noise. So Im guessing maybe the rest is from the cooler having now rubber grommets for the pusling problem. I remember when I was in the navy and worked in the engineroom we could tell if a rubber boot went out on the platform for the engines, it'd give off a little sound. Z1 does have reasonable prices but I got mine from Nissan North america through their consumer affairs line. I haven't heard any success from anyone on here as far as getting rid of the noise problem, its frustrating that it is there in place of hot oil temps. I guess I'll just get a loud a$$ exhaust to dround out the whine? yeah buddy!!!!
