New Engine Noise post-Oil Cooler Install

spearfish25 · 06-20-2011, 11:57 AM

The noise mine makes is similar to nabenson's. It's just not a big enough deal to bother with, so I've grown accustom to it.

So im bumping this back up from the long long ago.

I installed the Fast Intentions oil cooler this past weekend, and I have the oil cooler whine that everyone here is speaking of, it sounds like when you have a bad PS pump. It increases and decreases with RPMs, and really only starts once the engine/oil have warmed.

I replaced the filter last night out of caution, retorqued the sandwich plate and all the AN fittings, but the sound is still there. Has anyone ever figured out how to kill this noise? Its loud enough for me to hear in the car while driving in 1st and 2nd gears.

I have the Z1 34-row kit on mine with the optional protective sheathing and no noise. I wonder if the sheathing has something to do with it.

Same here. I had the Z1 oil cooler with covered hoses, no noise. And no I'm not deaf.. I could hear the ECU whine loud and clear.

im with LostSol I just installed my 34 row last week, I have the smallest leak I could imagine so I need to install the lines on the sandwich plate dry and try that, but I have the whine sound as well if you Google oil cooler noise it's kind of a common thing it has to deal with the stainless steel lines touching the frame somewhere and your hearing the pulsing vibration of the oil going through the lines.

heard people dull the sound with heater hose from a hardware store that they use on water heaters. go under the car and follow your lines and see where they touch or think they are touching and wrap the part of the line and zip tie it. could also have a second helper move the lines while you rev the car and isolate the noise and then wrap that specific part as well. ill be doing it this weekend.
