so i got my 04 350z last about 6 months ago with about 125000 miles on it give or take some miles. it now how about 136000. but im starting to hear some unsettling rattling coming from the engine when in neutral. when i lightly press on the clutch you can feel the rattle and it changes tone. (side note: when i got the car the clutch was and still is extremely hard to push down. i have driven plenty of other manual cars to know that it probably shouldnt be this tight. the dealer i got it from said they put in a new clutch but recenlty i have had slips and while in gear and random times that make me question that.) also there is a clanking when start moving but it goes away pretty quick maybe its just clutch work idk. im thinking my clutch might be going out but honestly i have no idea this is my first manual car that i own. none of these issues were present when i first got the car i know that much. anyway, this is first car i have had that actually really like and i just put 1250 bucks into custom subs so im really not ready to get rid of her. i am getting ready take the car to nissan next week. if anyone knows whats going on or has any ideas please help!
i have been considering doing an engine swap. im not sure what engine i want to put in there though or if i want to get help in building an engine or rebuilding my current one. if anyone has any ideas on how to prolong the life of my z please share. i would to be as cost effective as possible. im not working with a tone of cash.
much thanks.
