Smoke from oil cap? HELP!!!!
I cant find anything about it but... I have a massive amount of smoke coming from my oil cap when the car is running? Smokes like a train...? is this normal? I dont get any smoke out of my exhaust at all.... no coolant in my oil and no oil in my coolant.... I just have alot of pressure in my crank case after my vortech install... I even installed 2 catch cans and ran them to the supercharger filter.... the catch cans are working but I ended up blowing my spark plug seals... I spent all last night taking everything apart and then rtv'ing everything and making sure it was all sealed up nice and tight... now I have the smoke just rushing out of my oil cap....? Please help.....

Of so...yeah I think you have some plumbing that is misrouted.
I installed the kit last weekend... then Chris Macellaro tuned it... I think he called you about it Shariff.... it was on wednesday... he was tuning it and it blew the spark plug seals while it was on the dyno.... I just put all the pcv stuff back the way it was and when I start it there is no change... it just shoots out of the oil cap with about the same pressure as you feel coming out of the exhaust.... there is no smoke coming from the exhaust though.... its all clean.... also when I drive it the car hesitates really bad... it feels like it is missing 3 cylinders.... and if I floor it my AF shoots up into the 19's and 20's.... my car is all kinds of jacked up and I dont know what to do...... he put 2 identical maps on my utec and I even tried switching back and forth between the 2 of them and it does nothing......
Edit: Today I also changed my plugs just to make sure that wasnt the problem with the hesitation, and I checked to make sure all my injectors were firing, along with my coil packs.... everything that should be working seems to be doing its job....... but not lol

nope... then it just shoots out from 3 different locations.... the oil cap.... the back of the drivers side valve cover... and the pcv valve..... looks like a damn smoke factory.... the thing that bothers me is that its not smoking from the exhaust.... how is the motor bad if there is no smoke or knocking.....
I havnt really talked to him.... he tried to call Sheriff to ask him if he had ever seen anything like that before but Sheriff was tuning a car when he called..... it has just gotten worse over time I think.... I am about to just sell the supercharger kit and buy a built short block lol.... at least then I know I am starting fresh.... I have done a lot of motor swaps... I am sure I can do one on a 350Z.... I just need some more tools....

no im not sure but I have tried everything with the pcv system..... it just blows so much pressure out I dont know what else I can try.... Maybe thicker oil? hell I dont know.... I am using mobile 1 10-30.... but I dont see how that would hurt anything... thats what I have been using for years....... I disconnect the pcv and smoke just pours out of every hole.... and if I connect it then it will just blow all the seals in the motor again.... I have been fixing seals on my motor for the last week... I replaced my valve cover gaskets with new once... then after that I just rtv'd everything.... now there are no leaks but I cant even test drive it because it feels like im running on 3 cylinders.... which... I know im getting spark and fuel.... the only thing left that I need is compression... I dont think im getting that.... I am just lost and tire of screwing with it.... every day this week I have spent every free moment on my car..... its just getting retarded at this point....
well id try one last think pull out all your plugs and squirt a small amount of trans fluid in each one of the cyl's. un hook the fuel pump and put some rags over the spark plug holes and bump it over a few times not trying to start just enough to kinda spread the fluid around. Put the plugs back in hook up the fuel pump again and start it up its goin to smoke out the exhaust like a bi*ch but let that run out with your pcv un hooked and let me know how that goes. again my .02
well what i have seen happen and not in 350z so much as altima and sentras is the fuel will flood out the cyls and by squirting trans fluid in it and soaking the walls and valves it helps pull the compression back up. so if it starts running better and stays running better be happy if it runs better until it stops smoking out the exhaust then its bad.
