    Posted: 20 Nov 2017 at 12:20pm
One of the spark plug tube seals on my P12 QR20DE is leaking and may be causing misfires due to the collected oil in the spark plug tube.

Are the spark plug tube seals serviceable?  I see allot of people buying both the valve cover gasket and valve cover together.  Also, do the QR20DE and QR25DE use the same valve cover, as it seems some places sell them as interchangeable?

As an example, this place sells the gasket and tube seals as a set for the QR25DE:  https://www.ebay.com/itm/Valve-Cover-Gasket-Fits-Nissa-Sentr-Rogu-Altim-2-5L-DOHC-QR25DE-VS50777R/272483057503?epid=2102380410&hash=item3f71417f5f:g:dFgAAOSwnJVZmArB&vxp=mtr
