Just got a 93 300z was told that the engine "locked up" wondering if anyone has opinions on what it could be or previous experience with this problem

Someone may have ran it with little or no oil... bad stuff! You bought it like that? Probably gotta get a new motor, buddy....

naw. it was given to me.. said if i could fix it i could have it.. I was told that It had oil.. the actual owner thinks it might be a timing problem.. because it just skipped and then cut off.. didn't run hot.. or do anything out of the ordinary besides stopping hah. I dont' think he's actually had anyone real take a look at the car tho

if the engine just locked up, it is most likely something internally broke. either you will have to do a complete rebuild or buy another engine.

I've only ever heard of that happening when someone runs them WAAAAAAAAAAY too hard, then just shuts them off right away when they get home. They need time to cool a little...for the turbos (if it has them) and the engine.

What I'd do if I were you is pull the engine (or just ship the whole car) and ship it to sgp racing in Texas. Have them do a complete rebuild on it with all new, up-graded parts. You didn't pay anything for the car, so you're basically just paying whatever the cost is for the rebuild service you choose....kinda like getting a like new, race-prepped VG30DE(TT) for as little as $2,000.

I think ~7 grand for a race prepped, essencially new, damn near bullit proof engine isn't too damn bad. Wouldn't you like one of these put in the car you got for FREE....

Well seeing that picture just made my heart drop. Very exciting!! Wish i had gotten mine for free to do that.

But anyway, as they said, I would suggest the same. You got it for free, Spend the cash on the new engine and you will prob be saving rather than if you bought one from someone.

Good luck

Nice, shiny, new VG30DE....yummy.

i just have to say that the sgp site is awesome, and i would love to save up some cash for a new engine and trans. but ya know, what kid is made of money now a days :disappoin

I've talked to a couple on here....one 16 yr old kid that was asking what to buy to mod his new 350Z....little weary of that whole thing.....

hey long live i like the pic of another Z better. my friend has a silver one turbo, 5 spd its pretty hot, ill make sure he sells it haha

Well.....if you (or, if ANYONE knows, for that matter) know anyone selling a 5-speed 86-89T, PLEEEEEEEEEASE let me know. I get paid thurs and I'll have about $1,500 to spend. Lemme know.

Oh yea...thanks for the props, too. I got the current pic off Cardomain...hope the dude doesn't mind that I bum it. He really does have a beautiful 86T. That is what I wanted to make the multi-colored one into. Oh well. Besides...I'm hosting the pic off my own photo site, so I doubt anyone will mind.

what's with the factory alarm. I didn't even know that the car had one until the lights started flashing one day when I got out of it. Now she won't start. can anyone help me with this?

dude...sounds like the timing belt snapped. this could mean replacement valves, a full rebuild, or jut replacing the belt with alot of luck.

you would have to tear it down to figure it out.

good luck.

holy fucking old thread
