Gav240z

This is something I've never noticed my 73 240z had the overflow tank or vent tank and my 260z was well a 260z. My current 72 240z is soemthing i never checked for interesting.

Hey dude went through your gallery once again. I saw your reply to the white interior i mentioned a while back. Yes I am in Melbourne and I still have the Z . I've met a few Z nuts down here and thinking of starting a club or a group for the local younger Z guys. Don't wanna detract from the NDSOC as such more get a group of young guys together who can help each other out. All those spots are repairable however I wouldn't worry too much about it for now it really depends on how you wanna go about your car. If you wanna get it fully restored and do a group up rebuild don't bother fixing those places yet clean them up a bit perhaps but save that money strip the car down and pay for a decent rust repair and respray. As i say depends on what you'd like to do with the car if you wanna get those places repaired I'd recommend Rob at Zworx 95875500 in Mordialloc he's done some repairs on my Z when i got it and he's certainly had the experience.

oh me me me I know this one . Seriously it could be any number of things you need to describe when it's happening and how often. Just one other thing to look for though is if the carbs are too rich? If they are really rich it can foul up the plugs and it can splutter and backfire and carry on. It's nothing to do with your exhaust system more your timing. Your valves could need adjusting because if there not fully closed on the firing stroke you could get the firing noise through your exhuast. Check your spark plugs also and your electrical timing. As i say any number of items could cause it. :cheeky:

It could very well be the coil, I know that when my module from my distributor was on the way out the car ran like crap felt really unresponsive etc.. I thought it was the SU's making the car run crap I'd rev it and it just didn't seem like it wanted to rev. When i replaced it wow what a difference the car came back to life I took her for a spin yesterday dunno if u read my last post "Help Z Playing Up?" i was having troulbe with it but sorted that out. Then cause I hadn't been behind the wheel in so long I started going nuts must have given her a bit of stick and just didn't care because I have 3 spare engines And the new head will go on soon . What a blast it was to drive and drive hard too . Anyway off topic it could be a number of things I had multiple problems causing hell in my car all small things i can't help with testing how good your coil is go to a auto electrician they should be able to check it. I know stock coils on early Z's play up when the car gets warm.

Are you talking about the 290kw Ford Falcon? Apparently there pretty good seen a few around punching it too not bad but the body style isn't for me.:classic:

I like my stock Z's but if i was to keep mine bone stock i probably wouldn't drive it either or at least not much. I like stock alot so much so i almost went that way but modifying is good especially things like improving suspension. Changing cams, doing engine head work etc.. I like nice rims too the hubcaps are a taste not too aquired by myself. As i said i respect but I'd prefer to update my Z in the smaller ways while still keeping her with a good degree of originality. I find originality isn't practical when it comes to things like hard to get parts such as the original engine bay hoses or stock tyres. If i was to do so as i say she'd stay in a garage. At the end of the day however if you like yours bone stock and it makes you happy then great I love to see a well looked after unmolested Z . Keep up the good work!!

Problem solved. Turned out to be a number of things all at once. First was the fuel leak I believe caused by the removal of the intake manifold recently I think it caused the fuel hoses to get streched a bit and come slightly loose so I tightened them up was leaking in more than one place . The next problem the reason the car stopped running lights went off and tacho went silly. The earth lead to battery terminal was cracked causing poor connection. I knew it was cheap when i bought it. How do I know well i started car again today first time fires over as usual. Then stopped after it was running like crap, went to start again no go, played with battery terminals and voila fires up again. So need new uncracked terminal. Finally the roughness backfire and other carry on can be attributed to a rich condition. I think the carbs seats are worn causing a rich idle and fouling up the plugs. I will get the car professionally tuned when new engine head goes on. Also the tappets are out of adjustment but no point adjusting them when im changing engine head soon. Thanks all for the advice. It's always something small. :cheeky:

No gasket gew is neccessary however i would recommend fastening all bolts first and then tightening in a cross pattern to ensure a good seal. To check for exhaust leak use a cut off garden hose and put near seal and check for flutter noise. I know the exhaust shop who cut a section at the extractors so that I could remove the exhaust and get to the gbox easier didn't do a great deal with sealing and possibly used gasket gew and it's still leaking I didn't take it back yet car hsan't been on the road but i'm pissed off with them because it's something so simple and they can't get it right. The old do it yourself if you want it done properly often applies :stupid: .

Anyone mention the 300zx Z31 in rocky 3 or 4 the one where he fights the Russian that kills his friend in the ring. I think it's rocky's wife's car .

New update. I checked battery terminal but found it seemed ok in terms of contact even if it is cracked. I started the car expecting it not to start after last night. To my suprise it cranked over very roughly tried adjusting electrical timing and nothing if anything adjusting it makes it worse. I get a lot of dark smoke as if a rich condition which means most likely poor ignition thinking either coil or module again. Anyone know if the distributor and coil not working properly would have an effect on not being able to crank over the motor even without spark?

Yes Bambi your probably right she probably heard about me going to video tape the hidious act . I think you all have a few good suggestions since it was 1pm at night i didn't do much problem solving had a look at the coil connections and everything. It could be a problem wth the battery terminal i replaced the negative connection recently because it had been overtightened and cracked the connection so i thought i'd replace before it gave grief problem was the auto shop i go to only had 1 type made of cheap $h!t metal coated in some pretend gold coating. I couldn't get them to fit properly without having to tighten very hard and that caused it to snap. therefore it could be snapped and hanging off i haven't checked but it did cross my mind last night. What exactly do fuseable links do? I was thinking these could be the problem but i really don't know much about those. As i say fuses are all normal. I guess i shouldn't rule out the tacho being the cause but even in my old 260z where it wasn't working at all it still allowed the car to run. I have a spare but the hassle to remove and fit again is well a hassle so i'll try other stuff first. I hope it's not the module cause I don't want another second hand one but a new one here in AUS is $800 . I know that the fuel leak is another issue just from the way the car was acting but I guess it's time to replace that hose. Anyway more investigation and we will see in the mean time any suggestions appreciated.

Ok well tonight I wanted to drive the car for the first time in a month probably. Last time I had a problem it was with the module on the distrubtor and caused all sorts of headaches.(electronic distributor). Today i cranked her over took a few more turns than normal and coughed to life revving pretty hard. Then she started spluttering and i was tapping the throttle and keeping her going I was pulling out the drive and it started to get a bit worse then i smelt a fuel like smell decided nup not going anywhere popped the hood and found fuel leaking where the hose connects to the fuel pump(mechanical). Fine that's a leaky hose most likely, that's not it look at the distributor and she's playing games saying im doing 4000rpm when it's barely idling. I put her back in the garage and switch it off. Tighten the hose to see if it will leak again still a bit confused. Try to turn the key once more and nothing no click no crank not lights everything electrical is dead. Really unsure what's going on . Any ideas fuses look ok. The car was running ok before nothing major was gonna replace head with new e88 with large cam but with the car running how she is a bit lost as to what to do. The hoses arn't 30 years old either there about 10 years tops. I can fix a fuel leak. :disappoin

it's not the screw holding down the spare tyre is it? What about the hatch is she firmly on?

yeah she's an old lady and i look after her but she's still sexy and I like to think old ladies still like to feel young . I'm at a stage where i can fix about anything on the car now myself except the body work that makes her so sexy so don't worry if i break something I deserve it but I'll also make sure i don't be silly and attract too much attention maybe somehwere like a private car park with my mates . Then again I don't like thrashing her so maybe not but 1 video might not hurt hehe.

just wondering how they got there headlights to go blue like that. I think my Z would look good like that. It's funny how you guys know this car as a 240sx here in australia it's a 180sx. Fitted with both a CA18DET and SR20DET in later models

Hence the reason I never pump it . I pull the choke half way crank it and fires over straight away. Do you guys have electronic ignition or are you using the points set up still? My old Z's didn't have this and took a few turns.:classic:

my car is a beast fires up first time everytime. Cold or not sometimes it might take 2 cranks but almost instantly fires over to 1500rpm. I have stock SU's I use the choke and I have an electronic dizzy I think this is what helps most. I never even bother pumping the accelerator.

if your passionate enough it will just come down to the $$$ at the end of the day most of those areas shown are repairable if not all. My car was in a slight knock at the front also and it doesn't quite line up the way I'd like but I'll be fixing that when it come time to strip it back to bear metal and fully restore her. It just depends on if you wanna fix her up or not?

Very sexy car if you saw my webpage a while back. www.geocities.com/gavin_doolan/ you will notice I included your car For the intro section anyway . Black cars really show up dust and when they haven't been washed it's funny cause white cars are the opposite you'd think otherwise wouldn't you? Red cars don't like the sun on a daily basis But I love my red Z.

I'm not sure rick I had a clutch problem for a long time that i thought was a gearbox mount as it happened downgearing and would cause a shudder been told you can't get them anymore I bought a good second hand unit. got under the car went to the effort of pulling her out and discovered the one in there was near perfect. It could possibly travel have you checked for playing in the driveshaft there bolted on tight arn't they? You've made sure the top of the struts is tight at the shock tower also? I've never replaced a set of struts myself so i don't know if you can muck anything up yet . have you jacked the car up and tried for play with the wheel it self does it stay firm if u try move it side to side. If there was any way you could recreate the noise I think it might help i'm all outta ideas but.

I understand I'm a newbie to ZX's but I'd like to learn the fuel system as I'm thinking of a career with computers and the tuning of cars and using computers to diagnose cars and prep race cars . Not sure if i'll go that way but I have an interest and I will probably go turbo FI in my 240z one day even if it's not permanent. Compression test could be ok but oil rings could be the problem with the smoke.
