Nissan GTR R35 Plug Seal

Nissan GTR R35 VQ38HR engine rocker cover have 3 spark plug holes each side on the rocker cover as like the one in red circle in above photo, but one may notice the plug seal is not a service part under Nissan genuine parts option, although you may change to rocker cover gasket, it may be headache if the oil leak is from spark plug holes area.

In the one GTR forum, we found that some of the GTR owner had found out that one Subaru model crankshaft oil seal size is just fir nicely for the R35 plug seal purpose.

Although the oil seal price may cost higher when it compare to those VQ20DE and VQ30DE plug seal, which is under Nissan service parts, it still worth it if compare to change a whole new rocker cover.
