i just changed my spark plugs and the last sparkplug i pulled out was soaked.

i asked one of my friend who goes to UTI and he asked his teacher at UTI and he told him that that cyclinder is not working and right now i am running in 5 cyl. is this true? if so you think dealer will tell me what the cause is?

its killing me, please help me out

 

need more information. Did you do a compression test? Was the car running poorly, maybe like it had a miss? Does it burn oil? Does the car get very poor gas mileage? Is the car modified extensively? Is the car running a turbonetics kit and you did a top speed run for 10-20 miles on regular fuel? Do you drive around on the rev limiter because its mad jdm cool?

 

no i have done any compression test, and yes car burned like quart of oil.
also i get poor gas mileage compared to other Zs.
my car is all OEM with intake thats all
even plug was oem

please help..

thank you

 

you're just guessing if you haven't done a compression test, for all we know your coilpack is ****ed up.

 

wet plug is no spark,unless it's wet with oil

 

Does it have oil on it?

If that's the case... it's probably just your tube seal leaking.

 

if you werent firing in a cylinder you would get a misfire code almost guaranteed

 

I had a problem with misfires after changing my plugs for the first time a while back... my problem was that I put the coilback on the wrong plugs..... i mixed up the placement because I didnt mark them before removing the whole coil pack.....

 

1) Check for a bad coil pack
2) Check for oil on the plugs
3) Check for any pending code(s). You can have a code and still not throw a CEL.

 

if he was running on 4 cylinders he would know and the thread wouldnt be about a wet plug

 

i just got call back from nissan and they said there is leak from the tube seal...

how much would it cost me ??
is it possible to replace by my self??
any more info will help

thanks for helping me

 

Thats not a uncommon problem and your engine will be fine but i think the valve cover has to be replaced.I am not sure but reading on here is they dont sell the tube seals seperately.

 

+1 i bought used set of valve cover from one of member here. It's common issue, there is no point to get a brand new valve cover.

There is couple more in Maintenance & Repair section.
If you want to get brand new valvecovers, AAANissanparts has cheapest price.

is it difficult??
