M35 VQ25DET rocker cover leak
Hey guys, got an interesting one here. Popped the bonnet the other day as something didn't sound right, could hear a hissing sound like a boost or vacuum leak. Pulled the compressor out and did a boost leak test. Couldn't pinpoint the spot until I put a small hose line into my ear and fished around, turns out the air leak was coming from below a coil pack. Obviously it is coming from the rocker cover seal, the funny thing is that there is no oil passing through, just air, spark plug well was dry as a bone.
Has anyone experienced this before?
Would this be considered a boost or vacuum leak?
Im wondering if in fact it is a shagged seal or maybe the pcv has shit itself and is causing this. As most of us know the seals are non serviceable and new rocker covers are around $300 each. I managed to find a passenger side for 180 brand new but it is the drivers side I require and cheapest I cold find was $318 delivered. I have simply put some 3 bond onto the coil pack seal to try and temporarily seal it up, haven't started it yet, letting it properly cure.
Has anyone successfully changed seals of an existing rocker cover. You tube methods look uninspiring, lol.
Thoughts and experiences please.
