Sigh. What could this be after valve cover change?
Been a stressful day. First start of the new valve covers didn't go well. There's a loud whistle noise coming from the passenger side or from the plenum. I put a stethoscope on the plenum and could hear the whistle. Couldn't do too much because it's night time and it's pretty loud actually. No check engine lights and the idle was normal for a cold start. Sorry for the crap video but I had to be quick to keep the neighbors happy. I'll try and get a better one tomorrow if needed. Any idea what to check for?

Some are going to scream here but if you have a propane torch, open the valve on it and run the torch around the area you suspect and see if the engine speeds up. You can do the same with WD-40 although it's messy or carb cleaner which is far more dangerous. And I guess I have to tell you to NOT light the torch.

The pcv valve hose fixed my issue. Cant believe it whistled so loud like that. I saw Z1 sells all three hoses together so I'll buy that soon. The intake tube to driver valve cover hose isn't too far from failing I'm sure. It felt just like the other hoses that broke. If anyone plans to do their valve covers or remove those hoses I would buy the hoses ahead of time. The coolant lines felt fine and were still flexible. Just seems to be the ventilation hoses that were beat
