Aftermarket valve covers w/ replaceble gaskets
I think we need to understand what the root cause is. Is it the seal degraded , the seal shrinking or the OEM clearance between the seal and the spark tube not correct from factory. If the OEM seal is okay the easiest way to fix this could be making a sleeve that goes over the spark tube to seal up the gap between the tube and the seal.

Found the QX4/Pathfinder valve cover for the driver side only for now. I only had the passenger side VQ35 cover to match not the driver side bc the online inventory said the junkyard had both. I traced the outline of the QX4 one and went back to the shop and it matches the driver side VQ35 one. The coil packs also use 1 bolt each like the VQ35 one. The junk yard only had the driver side and said they would call me back when they have both.

I have both covers now but the passenger side cover doesn't work with the coils from my car. The Pathfinder/QX4 coils are different than the ones from newer VQs. Only way to make it work is to use 1 01-02 coil. I read there are problems with them though.
Gasket fits perfect.

Do you see any grey dots on the coils? The grey dots on the coil was suppose to mark the updated part number that did not have the misfire issues of the earlier coils. I remember this issue from my maxima days.

I dont have any of the 01-02 coils. I will have to go to the dealer to ask to see those coils and to check for grey dots tomorrow.

Went to the dealer and as I suspected only 1 coil is different then the rest in length. I paid $127 which is really high compared to online prices of 89+shipping which no more than 10-15 for all 6.
This should work now. But wont know for sure until install time.

It looks like you could possibly just swap the boot over. The soft rubber is two pieces. The shaft portion and then the top cap portion. Maybe swap over the entire assembly or just the shaft portion.

I already took one apart and I'm not sure if it works anymore. I'm going to leave it as is unless it misfires.
I have a 2003 with factory seals and 130k on it.. And only one of them is leaking oil. I really don't see the big deal in just replacing it with the factory seals again, they'll last at least another 6 years. Use RTV sealant if it makes you feel any better. Why go through all that trouble.



All those seals I bought was for nothing.
