Hi all:
I was swapping the plugs in my 1996 Nissan Maxima (117k) and noticed that there was oil on the coil and on the walls of the spark plug chamber for cylinder #5 (bank closest to firewall, the cylinder closest to the driver). I think the problem is the spark plug tube seal that goes in the valve cover and was hoping to tackle this soon.
Do I need to apply sealant along the entire length of the valve cover (in the gasket groove) ? How about on the head-side - any sealant there? (I plan on replacing the cover gasket, all 3 tube seals and use new grommets on the valve cover bolts).
I plan on cleaning out the EGR ports while I have the plenum off the car too.
Any other tips/advice from people who have done this before would be appreciated.
Thanks. Nirav
