92 300zx engine "locked up"

[nikitenko91]

i bought a 92 300zx and the gu that i bought it from said that the engine is "locked up" i dont know what he ment by that but when i try to turn the crank shaft with a ratchet it turns smoothly but then gets stuck, so i turn it the opposite way and it turns again but then after like 2 full spins it get stuck again. does any one know how to fix this?

[osiriskidd]

like...hydrolocked? or what...?

[IndianStig]

oil in the motor?

Well why did you buy it then if you dont know what it means? It means the motor is destroyed and buy a new one.

yes it has oil. so no one know what the problem could be?

If its NA then swap the tt engine in and if its tt then just pull the motor and rebuild it from the ground up.

Pull the plugs and try turning it over again

its not that its hard to turn it, it dont turn at all.

[speedminded]

its not that its hard to turn it, it dont turn at all.You said before it would turn one way then turn the other way but just not all the way around. Now pull the damn spark plugs and try it again :slap:

[EmotorsportsE]

Pistons hitting valves? Jump time?

[DaRussian]

i am thinking the timing is way off because it looks like it got new timing belt.

[khailon]

prob locked up b/c of no oil

[DaRussian]

it has oil.

[3.5altman]

probably didnt have oil when it locked up

I'm going to give you the best advice in this thread. If you're really so dense that you don't comprehend "locked up" and then...get this...you try to turn the engine by hand and it wont turn. Now what would that lead one to believe? That maybe, perhaps, possibly "locked up" means one of the following; seized, blown, "exploded", trash, garbage, giant paper weight, etc. Honestly, if you can't figure that out, go get yourself a nice civic dx, leave it totally stock, and drive it until you can afford something else that you don't need to touch.


Stupid kids man, damn.

i am thinking the timing is way off because it looks like it got new timing belt.How can you tell it has a new timing belt? You can't even begin to see the timing belt without a couple hours of work...

[DaRussian]

i got all the covers off thats how i see it.

**** you this is just my first 300zx i am fixing i am not that stupid maybe the timing is just off and i am not gonna go and buy a new engine.

[BlkCD5]

i hope you didn't pay more than 5g's for it. Setting timing is a ***** on those cars. Plus buying another engine to build isn't a bad idea.

[speedminded]

i got all the covers off thats how i see it.ah, well did you try turning it over with the spark plugs out?

[SiRed94]

my guess would be a bent rod....

[turbolaser6]

idk

[nikitenko91]

yall are ****in idiots when you take the spark plugs out it only makes it easier to turn. it iS ****in stuck you retarts! quit sayin the same ****in thing over and over!!

[Honngodda411]

sounds to me like a rod broke and it is hitting the inside of the block when you are turning it over. btw if you take the plugs out and stick a long extension in the hole you can tell if the piston is moving or not......if it doesn't move there's no rod connecting it to the crank...=your screwed. if it was or is locked up it will not move at all. peace

Now this is what I gathered a from a few posts and threads on here.


i am thinking the timing is way off because it looks like it got new timing belt. You said that it looks like it got a new timing belt recently.




ill buy it. how much? i was changing the timing belt on my z and i messed my pulley up.

That was from another thread ^^^



**** you this is just my first 300zx i am fixing i am not that stupid maybe the timing is just off and i am not gonna go and buy a new engine.


Ok so from what I have gathered from your other post's you were changing your timing belt recently and broke your pulley. So that means you lied when you said that it looks like it had a new timing belt put on because it dosent LOOK like it has you know that is has because you put it on.

Also nikitenko started the thread saying it was his car but in DaRussians post he calls it HIS first 300zx.

So who's car is it exactly? Oh and also...

HA reps for due PWNage.

But really, if your gonna post here kid you got to stop acting like a little ass. Now get outta here, go talk to the gurus on NICOclub or 300zxclub so they can tell you the same thing.

My take on this? Your deluded if you think a garage DIY job will fix your car in this state buddy, especially with no prior Z32 EXP.
