280z smoking after new valve seals
I will just start from the beginning. In august of last year I turned on the car and backed out, nothing weird, but then all of a sudden the car started to smoke really bad and misfire so I let it just run and then i just drove and problem solved. Over the winter I started the car and it ran for 15 seconds and then started missing and started to smoke(blue). And I wasnt going to drive it so I just let it run, the problem did not solve itself like the previous time. So I did some research and decided it was the valve stem seals.
I ordered the parts and began working, the job was my first serious job working on the car besides the simple oil change, etc.. The job took me several weekends but I got it done and I turned on the car this past weekend. It started strong and it ran really good for 10-15 seconds and then the same thing happened, It started to misfore and smoke(blue). So I went to a local nissian mechanic that works on z cars and he said to change the plugs and pcv valve. So I got a new pcv and plugs. I am having trouble removing the pcv hose so i have to cut it, but before I do that I will get a new hose. I changed the plugs and it ran longer for around 30 seconds and the same thing, all the plugs had oil on them. Is it possible that the problem is the pcv valve or something else. I serously doubt its the rings because the car only has 77k miles. It is a 1977 280z.
