Alright long story short im wondering if anyone on here has any experience working on Nissans or the like. My cousin has a 2003 350z 6 cylinder 3.5 liter, and it needs new valve cover gaskets. I have never worked on a car of this caliber before, let alone any jap car lol. I was just wondering how hard it would be to get the covers off. I mean i know im going to have to remove a bunch of stuff to get to them, but i was just wondering if there were any hidden surprises. I know its not going to be as easy as an inline 6 . Im confident i can handle it, but just wondering what was in front of me.
You are just talking about a valve covers here, if it was the heads it would be a bit more tricky but very do-able IMO . Google it or go to a Nissan forum and ask them , not here maybe and your odds will be much better there . Do I think I could do it ? Yes and the head too if need be, just saying .
I tried googling it and a few people were saying it takes a highly experienced mechanic 4 hours minimum. Some people said 6 hours labor if you took it to a shop. I thought those seemed like high estimates, and thought it might be because there was some out of the ordinary things you had to do.
I will try gooogling it too and see what I can see . Any chance that the PCV is clogged/dirty and it just msking a way to get rid of the pressure ? I would check that first and try tightening the valve cover bolts a tad first . Edit: have you tried asking on a Nissan forum too ?
The actual problem is the seal around the spark plug chamber. Apparently it is a common problem for this year group. Im sure my cousin is a member on one of the forums, ill probably just ask him to post something instead of making a new account.
