  1. L28 280Z Car engine problems!!!

    Ill check the dizzy/leads but im sure Ive check them more than once to be correct. Im trying to by a second hand intake off a late 280zx so I can grab the thermotime sensor and water temp switch. But unsure this will solve anything... The triple carbs would be my overall choice for what i would like, aesthetics and reducing the old dodgy electrics, however its a massive trade-off because I want to drive the car now, and dont want to spend the money.... Anyone got a cheap set of triples out there for me?!?!
  2. L28 280Z Car engine problems!!!

    Hi Guys, After a couple of dry weekends Ive managed to get back onto the Datsun engine, but shes still not running properly if at all. I corrected the dizzy shaft tang to what appears to me to be the correct tooth. See photo below. Now, Ive plugged up both vacuum hoses from the dizzy and purge tank respectively (see photo on previous page) Thermo time switch and water temp switch are both not fixed/connected either. I can finally get her running for about 15 seconds, sounds like its seriously missing/running on 5?... and then it dies, and unable to start again. Ive done this twice. I have half a tank of gas, and getting spark. Im really unsure what to do now!!! Very frustrating, living in a place with limited parts and limited knowledge on these cars!.. Was even thinking of getting rid of the whole FI and going for carbs! Any help would be appreciated. Thanks in advance.
  3. L28 280Z Car engine problems!!!

    Thanks for the replies guys, really appreciate it. I originally cranked it over post-rebuild without the spark plugs to get the oil up/check there is no bent valves, timing correct, etc but now thinking about your last post Site, the dizzy could be in the wrong way. (180 degrees around ), this would certainly make a difference right? I can almost assure you that the timing/tdc is correct as i had to do it twice! (broken head bolt, dont as lol). but i didnt check the dizzy when it went in. I get a popping sound out of the AFM when i give it gas while trying to start it. Think the dizzy in the wrong orientation is my answer! Will get to it this weekend guys and let you know. Thanks again for the help! Cheers JD
  4. L28 280Z Car engine problems!!!

    Hi all, Happy New years to everyone. After taking the leap of faith and tearing the engine down and rebuilding it, Im now at the nervous point whereby you hope everything is done correctly and hope she fires up.... and she didnt.... So some basic background on the engine. When I received it was running very rich and since checking compression and tearing done the head, found a bad valve seat in Cyl 1. After reconditioning the head, replacing the rings, big ends, new camshaft (after my original was stolen) put is all back together and she cranks over but does not fire. I have spark, I have petrol (injectors are spraying on crank over). Now to my nightmare.... The wiring was in pretty bad nick when i got the car, but have continuity tested all wires from the ECU and everything check out, the problem is some of the sensors have broken. The thermo-time switch is broken, as well as the brittle wires from the water temperature switch have broken. (see photos below) The car was also running a vacuum switch solenoid on top of the thermostat housing, (originally from Cali) which also has broken, leaving me with a some lose vacuum lines and wires I have no idea if that is contributing to it not starting. These parts are not cheap buying new, i think a new thermo-time switch is about £80 by the time i get it shipped to the UK, not really money well spent. Can any of you guys point me in the right direction of potentially removing/blocking up/ resolving these niggly problems and if they contribute to the car not wanting to fire??? Sorry for all the photos, but unsure where to start... any advice on any of these issues would be greatly appreciated. Many thanks, JD
  5. Certificate of Origin - Help!

    The DVLA over in the UK needs to see the certification to ascertain that it is the car stated. I didnt get any paperwork with the car, no log book or anything, just the California plates on the car. The shipping/VAT has been paid my end when it came into the country, I just need the 'certificate of origin ' for them to register it here. thanks
  6. Certificate of Origin - Help!

    Hi guys, Ive recently imported a 1976 Nissan Datsun 280Z with California plates from the USA to the United Kingdom. I would like to know how to get a 'certificate or origin' from the USA so I can register it in the UK. Ive contacted Nissan USA but they have been rather unhelpful. 1976 Blue Datsun 280Z VIN: HLS303114422 California Plate Number: 5WVN339 Can anyone help me with previous experience?? Many thanks, JD
  7. Camshaft NA to turbo swamp

    Great, thanks, I dont mind the 'horsepower' behind, i just dont want to chuck it in and start bending valves! Cheers
  8. Camshaft NA to turbo swamp

    Thank guys, sorry have been away on work. Check out the link below, it has everything Im missing.. Wondering if this would be a straight swap.... What do you guys think? Many thanks JD http://www.ebay.co.uk/itm/1983-Datsun-280ZX-Turbo-Camshaft-Clean-Nice-with-Sprocket-/222640225402?hash=item33d6643c7a:g:fL4AAOSwa4FZtH
  9. Hi all, Im currently reconditioning my L28e N42 in my 1976 280Z and have a bit of a problem. I took my head in to get re-conditioned, and i left my original camshaft with cam towers and chain sprocket in the boot of my daily driver, Rover P5b Coupe, which has since been stolen last week!!! So basically Im in need of a new camshaft but means i still need the towers/sprocket/bolts too. There is a Turbo Camshaft with towers on eBay which supplies all my needs, Im wondering if that will be a straight swap????. Ive had a look through forums and understand there is a difference between NA and Turbo camshafts however im wondering will the turbo one still work with none/minor tinkering?? Im trying not to over spend by getting a worked cam and then paying through the nose for the towers and sprocket which are very hard to source, especially that I live in the UK. Any advice would be great, or if you have a spare cam/towers/sprocket that works even better Cheers JD
  10. L28 280Z Car engine problems!!!

    Thanks guys, I went with Ring Engineering in West London,, they have found my problem, Cyclinder one valve seat was corroded to buggery. Will look forward to getting this back and start putting it back together. Also anyone got a spare stock camshaft with sprocket and mounts? I left mine in the boot of my Rover P5b and that got stolen last week. So down to one car now thats on blocks with parts missing! Speaking of which, I know its not Datsun but for all the UK users, if you see this old girl rocking around please alert me and the police, would love to get her back! 1972 Rover P5b 3500 Coupe, stolen from SW18 London around the 2nd Sept Cheers
  11. L28 280Z Car engine problems!!!

    Right, Ive decided to take a leap of faith and go the whole hog. Pistons are out, Sump is off, from timing cover is off. The rings seemed fine but there was a small water mark on the bore, and i slightly tired head gasket closest to the timing chain, which cold have suggested water getting through in the amount of time it has been sitting. Could be some of my problem there. Also the big ends are a bit tired so replacing those too. Gives me a good excuse to give the engine a good clean down and spruce up, just hoping it goes back together ok. Guys i need a full engine gasket set. Preferably here in the UK so I dont have to pay import tax and shipping! Also can you guys tell me the difference in L28 whether I need a 240Z/260Z gasket set or a 280ZX gasket set. Mines a 76 and i think im in a bit of a cross over when it comes to parts. Thanks
  12. L28 280Z Car engine problems!!!

    Hey team, Thanks for the replies, after going through what you guys had suggested and finding nothing out of the ordinary, I decided to run a compression test... (shouldve done this way earlier) to find no compression on cylinder one. I took the rocker cover off, the valves seem to move and seat fine. I used the compression testing kit and blew into the spark plug hole with the valves closed and could hear the air down the crank case. That has got to be bad rings right? After deciding to take off the head and inspect further, I found the exhaust manifold in no.1 totally covered with burnt fuel compared to other cylinders, See photo... seems like this has been the problem why she was overfuelling. Does this make sense all of my symptoms? All things going well i will drop the sump this weekend and try pull some pistons out!! Any tips on getting the sump out? I remember the sump in the L20et on my old skyline was a right dog to get out... Also any easy tips on whether the front of the block needs to be removed, water pump etc? thanks in advance JD

    Cool, youtube is better..Thanks will check this out over the weekend.
  15. L28 280Z Car engine problems!!!

    Hey guys, managed to get a couple hours in after work tonight, and good news... Shes running. Pretty rough mind you, but I turned up the Idle, and both the cold start valve (21, 47) and thermotime wires (45, 46) were around the wrong way... My fault entirely from replacing the corroded and brittle clips back when I got it months ago. I have attached a photo of the engine bay, anything look unusual??? Trying to up load a video so you can see how rich shes running... pardon the boxes of Stella Artois, its me birthday on Saturday hahaha Again, vacuum hoses off and running better. Unsure... Thanks again guys. Feel back in love with it tonight!!! Cheers JD IMG_6761.MOV
