so i took out my old spark plugs to day and found all 6 of them has oil deposit on it as shown in picture. on the top of that, i also found oil pooling after removing coil pack over in cylinder #2 but not any of the others. I've read the sticky thread and the guy was talking about cylinder #6 getting oil leakage. are we on the same problem?

i have only 39k mileage on my car. full warranty still valid til Dec. 2009.

 

Yup, same problem, try to fix it under powertrain warranty. how many miles do you have on ur car?

 

You are covered 6 yr 70K miles with powertrain and this is power train.


Go get the valve covers replaced under warranty.

 

Damn, I will check the mine after my new plugs arrive.

 

how hard is this fix if i was suppose to do it by myself?
Also how much is a valve cover?

 

I would just take it to the dealer. They'll fix it for free and they will put you in a fly loaner for a day. My dealer doesn't charge for the loaner either.

 

There is a 10 page thread on the subject:

i cant imagine any authorized dealer charging for a loaner under any condtions... i got myself in a coupe for a oil change free of charge.

 

I did the valve covers myself. You have to remove the intake, upper plenum, lower plenum and then you have access to the valve covers. I painted my new covers before install.

The passenger side valve cover was much harder than the drivers side because of the coolant rail.

All in all it took me like 4-5 hours. I'd give it a 3 of 5 on the wrench category.

 

Do you know how much a valve covers would cost?
also do we need any special tools?

my warrenty is over..

 

You can check out here for any OEM infiniti part that you need (http://www.infinitipartsusa.com).

But I did the search for you and here's a link to the valve covers. They are about $200 each and all you really need from what I have read is gasket for the spark plug tube. If this is the case I hope infiniti gets their act together and start to sell these separately.

Valve covers are easy to swap out. I have taken mine off a few times.

 

just changed my friend's 05 coupe's spark plugs today. found same problem. there are oil marks in the tube after removing the coil pack.

gg

 

for the seal/gromet problem? Of something else...

 

When I changed my plugs I found a pool of oil on the cylinder closest to driver on the passenger side. It sucks cause I don't have warranty and need to get a new cover. Anyone know how long I would be able to drive it for?
