I did the rotella t6 but after like 100miles it makes the noise again i repeat the t6 5 40 DID NOT RESOLVE THE PROBLEM list of oil i tried royal purple 10 30 high performance street the one with zinc, oem mobil 1 10 30, redline 10 30 all of them doesnt resolve this problem, from all that oil the oem mobil 1 10 30 eliminate that noise the longest, like 1k miles

 

I found that Pennzoil Platinum, the stuff made from natural gas, lasted the longest thus far.

 

Will this noise eventually cause engine failure or damage ?

 

No.

 

So far, for me Mobil 1 5-30 keeps the noise from happening the longest, almost 2000 miles. I've only tried Castrol 10-30 and Mobil 10-30. It makes sense to me that a thicker oil would help, but that's not what I'm seeing so far, especially people in this thread saying Rotella isn't helping. Also, I think I notice the noise more in the winter, which points to thicker oil possibly being problematic. What's confusing though, is that people in another thread said that Rotella helped.

 

So ive been reading this for the last few days and was wondering if its already been determined that the noise is not causing any harm then why are we still going on about this?

 

Still don't understatnd how this is 'normal' per the dealership. I hear no such noise on my 2014 and have close to 30k on it currently.

 

Because people new to the issue tend not to read the entirety of the thread, and/or want to hear by themselves an answer to this.

 

I'm not sure, but lots of evos are doing it. Mine started when it was brand new with the original oil.. I decided to change the oil at 1500 or 2000 km because it made a lot of noise, and I did notice that when draining the oil it was a grayish gross colour.. All subsequent oil changes have been normal. Therefore it's my opinion that driving 5000km before an oil change on the original factory fill isn't really appropriate, and that an oil change is due at 1000km,and then again at 5000 or 6000km on the odometer.

 

I did change my oil at 1500 miles or less when I bought it. That might be the only difference.

 

Hi folks.

I've owned a Ralliart for the past five years, and never heard this noise at all.


My Ralliart, like the vast majority of them, came with no oil cooler Yesterday I had an Evolution X oil cooler fitted. 100% new, factory Evo stuff - lines, cooler, thermostat, the whole lot.

And, driving home, I hear the exact noise described in this thread. Clear as day, between 2500 and 3200rpm, audible once the car has warmed up.


So my theory, after a whopping 12 hours of experience (lol), is that this is very much tied in with the Evo's Oil Cooler setup.


Off the top of my head, I'm thinking one of...

1. Different oil flow characteristics with cooler and lines, compared to it being blanked off.
2. The hard lines themselves conducting oil pump vibration, eg. harmonics around 2500-3200rpm.


...or a combination of both. Those hard lines come from by the oil filter, but hang via a bracket directly onto the oil pump housing itself... so it could be a harder working pump plus the design and fitment of the metal lines... right there on the pump housing.


Anyway, interesting!

 

Sounds like u on low gears.That pitch sound is normal.What about at idle?

 

It had nothing to do with gear selection. It occurred between 2500 and 3200rpm.

As with other reported instances of this particular noise, it went away completely when I changed the engine oil on Sunday night.

And, in line with others' experiences, I do expect it to slowly come back, too.


When it does, I intend to play around with some vibration prevention on the hard oil lines to/from the cooler. Lines that are fixed directly to the oil pump with a metal bolt and bracket.

Just get a louder exhaust or an open dump and you will no longer care about those little pesky noises!

 

The fact that I can hear anything over the sound of my two-year-old, track-hardened star spec tyres is a worry in itself, lol.
