New Engine Noise post-Oil Cooler Install

Kyle@STILLEN · 07-14-2010, 06:26 PM

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.
