Ok guys... This is a question on a Nissan Z (2.2 liter) engine from a truck..
I have been working on this truck to get the carb setup right.....after dumping it in the trash and putting on a new one, I have a problem...
When the truck is running, there is oil seeping from the # 3 & 4 exhaust ports, and a little from # 2 and truck is smoking like a freight train when I hit the gas. It has a slight miss, but only under load it seems to be missing on one cylinder.
It does not do it immediately after starting, I have to give a minute or so before it starts.
I've checked the PCV, its fine, it will still smoke with the line disconnected..
Is there a possibility that its a head gasket or head problem ??? I can't imagine three pistons all of a sudden breaking rings....
