good god, edit your message and make it read able please.

 

yea sure, if its in good condition

the hydrolic valve lifters make a tap noise which is high in pitch when compared to a lower pitch knock of a rod.

Jack the car up and if the sound is louder under the engine..then its your rod.

if its the hydrolic valve lifters, its nothing to worry about there is a spring behind the cam gears and if the spring isnt installed correctly or if its just missing it will knock or click.

WTF???????

no, it will not fit

for sale section?

the abs actuator located behind the passenger side

do you have your E-brake up? low on fluid? abs actuator?

yeah i have a 1990 N/A too. btu I still don;t knwo wtf ure talking about. that taping noise might be that ure due for an oil change. mine use to do that. put in some MObil 1 10-W40 fixed mah problme right up. (Along with OEM nissan oil Filter)

 

valve tap is very common on Z's. sometimes, switching to a thicker oil has helped it go away.

 

i picked up my 90 300zx na 2+2 for $3200. the suprising thing is that everyting works! Car is in pretty darn good shape.

 

cool? That was kind of random...congrats though. Start a new thread with the info on your car and some pics.

 

well every one im taking the 1990 300zx into the shop tomorow i will keep every one posted on whats going on with it.. so far i have done a Castrol Full sysentec oil change 10-30 k&N oil filter , put in 80w 95w rear diff oil, that stuff is rank i could still smell it a mile away !!!! i was told my 1990 has the VIS LIMITED SLIP DIFF ? should i be impressed? umm when i have more time i will be droping the tranny pan and doing the tranny filter and tranny oil, any one know how to do the ECU CHECK ?

 

Hold on as i read is there really a recall on a 7th month of 1989 ? somthing to do with the valves? 6 cylendar? any body know ? please i need help asap !

 

some of the 90's built in 89 had soft vlaves....im not sure about a recall though.

 

there's a link at Twinturbo.net under the FAQ page that tells u step by step.

 

Ok i took the car into the nissan car dealership to have then diaognois this littel problem i have they said the timing belt is so worn that its really slipping and hitting the timing cover? i havent had any time to check thius out my self.. is there a place were i can install the new timing cover and news tensionors myself? im gonna snap !!! if i have to pay 600 dollars to have a new timing belt put on.. any help yall ? any good links with pictureS? helps etc?

 

if you're asking for parts, check with courtesy or at ocncept Z performance. I believe Rizz's link page can help you out as well. As far as how to do it.....here...

I'm gonna go out on a limb here and say the you do not possess a thorough understanding of how an internal combustion engine works. I'm alos going to bet that you don't really know the side-effects of installing a timing belt incorrectly. If my assumptions are correct, then just have the dealership do it. If the timing belt is actually hitting the inside of the ttiming cover, then I suggest you have this done immediately. Replacing the timing belt is a 4 hour job. $600 isn't bad for having the dealership, if they do it right and replace the belt, tensioner, pulleys, cam seals, main seal and VTC springs.

 

Not to mention if there's further problems, you can take it back to them and have them fix it cuz they screwed it up.
and calm down, no need for you or the timing belt to snap. Just take care of it.

 

Ok people the 1990 is in the SHOP !!! i will find out in a few days whats wrong and whats not wrong but for sure the new timing belt is being put on , plus i talked them down to 450 dollars i dont have a hole lot of money to spend , darn i wish i had more time off from work then i would install the timing belt my self, and for all u people who think ( im some dumb *** ) i do work on my own cars my self ( you can only learn from working on them )

Learning from your mistakes is another good thing. I have a feeling that if you tried to change the timing belt on your own that it would be a good mistake to learn from. Just let the dealership do it.

 

in due time i will learn more an more...
