LR4 PCV Valve Question

[Aderry]

I am replacing the PCV valves on my 2013 LR4 and the kit came with 2 different size springs which do I use?


My issues is when I removed them the one closest to the fire wall was in good shape with a longer spring, but the one closest to the front of the engine the spring was rusting and completely compressed. So is it a combination of long/small or assuming the back one is right, is it two long springs? This is the NA 5.0L

Thanks

Both mine were the exact same.

Thanks from the picture do you think yours looked like the longer or shorter spring?

Mine where identical in length and looked more like the shorter of the two you have pictured.

Thanks I wonder if it’s a supercharged vs NA thing.

The shorter spring is for the 3.0 engine. I believe the longer spring allows more air in, hence the hissing sound (which is normal)
