New Engine Noise post-Oil Cooler Install

Jordo!

Can you record it? Could an oil line be rubbing against something?

I'll give recording it a shot, but I think it will be too subtle for crappy iPhone recording. Definitely not lines rubbing anything. The sound is perfectly reproducible and continuous with every throttle application. It's almost identical to the transmission whine (ie, whiiiiiIIIIIRRRRRRRIIIIIIIiiiiiiirrrrrrrr as throttle is applied for the first half and then released and the revs drop on the second half of the 'sound').

To be completely honest I don't have a very clear idea from your description as to what the sound is like. Is it a rattling noise? Is it a sound like air/fluid running through a pipe? I've never been able to "hear" an oil cooler before, especially from inside the car when all the major components are out in front of the engine.

How much fluid did you add? Did you double check your engine oil after the install was complete?

Where did you purchase your sleeve nut and oil cooler filter adapter/spacer? I have seen on these cars where the sleeve nut is just a tad bit too long. We actually trim ours down. If the sleeve nut is too long may not leak oil but it does prevent a perfectly flush fitment and can cause the spacer to rattle a bit...You want to fix this ASAP as it may not leak oil today but it might in the future.

Also, some people have mentioned that they can hear the flow valve/ball rattle in some cases. This would amplify as the RPM increases.

The system took just under 6 quarts of oil when I refilled it. I've checked the levels numerous times over the past four days and it's rock steady.

As for the noise, it's not a rattle, vibration, or buzz. It's a whirring sound almost identical to the sound of a loaded transmission driving in low gear. At low rpm (idle), I can't hear it at all. With some application of throttle and the revs coming up, I can hear it build and become slightly higher pitched. Similarly, it decreases in amplitude and pitch as the revs drop back to idle where the sound becomes inaudible again.

I'm using the same Mocal sandwich adapter (with included sleeve nut) that Modshack used with the exception of a 200F thermostat. The sandwich adapter has a nice, flush connection both with the car-sdie and the oil filter on the other side.

On my way downstairs to record it now.
