Sounds very like shot big ends. drop the sump and take off the end caps. The shells will tell the story - the bearing white metal surface will show wear on the stuffed one and you might also have wear on the crank journal - not so good. Not sure you can feel this but it will be obvious on the run big end once the shells are open. Dont mix up the big end caps - they're paired with the conrods. Torque settings etc critical with these when re assembling. If not too bad you might get away with new big end shells and a light clean up of the crank journals - depends on how long you expect the engine to last or how much power you try to wring out of it in future. Might need a micrometer to measure true wear and ovality. Proper solution if the crank is damaged is a regrind and undersize shells.

big end bearing rattle when the oil has thinned? Thick oil would only disguise it a little - it would only get worse and wreck the crank. Dont suppose its easy to get the sump off one of these to check the big end shells?

Check it still spins on viscous - with the engine switched off of course - spin by hand to see if it has a jammed bimetallic spring clutch. The load could cause belt slip if it is jammed and you would waste fuel power

I'm with Chris on this. If you ve got big splits on boost pipework you cant make any real boost. If you have something indicating 1.25bar with seriously leaking boost pipes I'd be sceptical what its reading. be interested in the explanation once you find it

You have to find out where the 3l of h2o went. Then you have to see if you've damaged anything - like a cylinder head gasket. Check your oil dipstick for whitish cream. Your exhaust for excessive steam etc. If alls ok and its just a hose leak or similar then you've been lucky.

Scottie any feedback on this subject? ne body?

allegedly toasted the tyres, bent a driveshaft and rogered the clutch doing max rpm standing starts. Bl00dy sacriledge on an old timer jag like that! but then again tp gear give back all their test cars with no tread on the tyres or meat on the clutch! Its funny how cars you dont own can be made to really really perform And I thought the stig was Nigel Mansell too!

http://rides.300zx.co.uk/rides/135/Copy_of_coolzed.jpg does that work - well it hot outside!

maybe servo motors that open and shut the various vents to when controlled on auto - the auto aircon section of the manual is enormouse - could do a phd on it. Maybe you have some leaves or something stuck in a vent and its fouling the door flaps and stopping the servos - just an idea or a little animal in there that doesnt like the cold:)

also could happen with a duff Sky digibox. These things are programmend to call up sky using your phone line and transmit data on what you view back to sky. Yup your own sky spy!!! Our phone would chirp sometimes and when you picked it up there was nothing. Then I noticed one time a led flashing on the sky box as it happened. this led goes out immediately as soon as you lift the phone up. It must be programmed to hang up if you lift your phone up and it will ring sky quietly again later. Cure is to pull out the telephone connection to the digibox. The sky contract says it must be in but so what. Also heard that if this goes wrong big time it calls up other people and you get charged for the calls. Basically it should be programmed with a sky freephone number to upload the spy data on you!! If it gets some other persons number it gives them a quiet call! quiet because it waits for a digital signal handshake.

Dont understand this - how can you ever reach 1.25bar with a boost leak. Either it leaks or it doesnt and 1.25bar tells me it holds pressure pretty well. Hope it aint detting!

Yes Zimon for sure. "we" is always growing as others integrate into "we" but there's a lot who will never be "we" coming in now. They want (demand) us to be as them. These previous waves of immigrants were / are the "spice" of life and they got their heads down and worked here. People made it tough for them too. No I'm talking about the religious nuts who think God likes being praised all day rather than seeing a bit of work getting done, I'm talking about the ones on the DSS take and taking black economy, the ones claiming dole in several towns, the ones who are not the slightest bit grateful to share this land. The sword fighters in central Slough and so on

You should maybe look at rebuilding it. Its basically a bunch of power transistors. Check it with a local electronic engineer. But the price in the link from Vijay might be very tempting

from 01/08/92 same day mine was first registered - legally you must have em. Reality is they may not check on MOT as the zed may not be listed in the cat database. You are even supposed to tell your insurer about this too. On that clean underside shot - is that 3 boxes on each side? looks like 2 each side upwards of the diff! must be quiet? Mine only has the Apexi cans on the end of the 3" plumbing with nothin else - hence the sound / noise depending on your point of view

3.7 degrees negative on the front suggests your top link bushes are worn too. The top link mount studs have plenty length if you want to make up shims for behind the mounts. Just fitted new Nismo bushes on my top links and the front wheels look very vertical now - not measured tho. If its on the rear have you checked whether the stock adjustment is already maxed out or still at the oriinal factory setting?

but thats marketing strategy, first you cream the top layer who will pay the most then the next and so on. Look at telly's and PCs. Its nothing to do with fair.

Just fitted these Nismo bushes to mine too. What a bitch getting the inner mounts off the inner wing. The nuts were so tight. Although I could only feel a little play on one side of the car and it has passed 2 MOTs like this the links on both side had loads of play once the suspension weight was disconnected. Strange but the old bushes I knocked off the top links were similar but not exactly the same as the new Nismo ones. I was expecting to take off plain rubber ones not greased bearings with rubber seals. The part numbers of the Nismo ones start with the same first 5 digits. The new Nismo ones also say competition use only?? Same bushes are on the Courtesy Nissan site. My service records on the car says a Nissan dealer changed the top links 30k miles ago. So they did'nt last very long. I wonder if these Nismo ones will be any better. The car is running 18"X8.5 front. Maybe the heavier wheel and less bump absorbing lower profile tyre is wearing the damn things out quicker than normal. Still the steering has gone nice and direct now. There is no noise over potholes etc and the front end feels all tightened up as it should. I think, as Scott also says, uneven tyre wear comes from this as the wheel will lean more on cornering due to the play and scrub the shoulders. Willie

I blame satellite tv and WMD (culturally anyway) like Baywatch. These tight ar5sed religious cultures breed mind control fundis who keep women down and ensure nobody questions why things are the way they are then boom they see Baywatch and they pay their life savings to get anywhere west of manland Europe preferably! More and more are seeing what they think they are missing! and they are informed the dss is paved with gold. The trouble isnt a bit of immigration of talented hard working, smart, law abiding people ready to integrate into and contribute to this society. Its all and sundry, the feckless, the workshy and culturally crippled from half ar5sed cultures that cant organise a bit of farming or even allow a piss up in a brewery and the first thing they do when they get here and enjoy the local hospitality is to try to shove the same dumb ar5sed culture down everybodies throats here that helped make where they come from the half ar5sed place it is. The worry that the bnp feeds on is that there is an endless supply of potential immigrants that wont integrate into this society not the odd wave over time that easliy integrates into a society. The information age means people everywwhere become informed faster of where they might go that's better than where they're at. Ever decreasing transportation costs means the means to get here are coming closer to them. I am all for enabling others to succeed and develop their own countries. I respect those that work hard and contribute. I'm not for unlimited hospitality here though.

I did it myself. Had a bad experience one time with a "proper job". I know it doesnt mean they are all bad. I used a crude but effective track guage made out of 2 pieces of wooden profile curved one side flat the other each about a metre long or so about as thick and broad as a normal ruler and placed back to back and held together with a couple of elastic bands. Sort of thing you find at B&Q near dowling stuff The 2 pieces slide against each other and the laccy bands hold them tight together but still allow you to use it like an extending rule. Get the picture? Then you get under and extend it to meet the wheel rim at as high a point as possible behind the axle then without disturbing the inside track measurement you just made you try in front of the axle same place on the wheelrim. With toe in it should be a lessor measurement and need pushing in. You check the back again and see how much gap difference there is back to front. We are talking a couple of mm here so do it several times to get an average or to be sure you are measuring right. I did front and rear like this and after a couple of thousand miles the tyres are showing no sign of wearing wrong. You adjust the track arms exactly the same amount each side - we're talking half turns here each check. If you get it wrong your steering will be all off centre! So maybe count visible threads each side and make notes! If you feel this adventurous that is. Its at your own risk! When I first got the car it had 7 or 8mm toe in on the rear after a professional had fitted new rear track arms. The tyres were disappearing and the handling was diabolical in the wet. I think as well that just about every zed around 10+ years old will have a little sag in all its rear bushes and springs meaning more than std negative camber. You might as well adjust the rear camber to the max positive setting first and believe it or not check it with a spirit level. On flat level road you can see that you'll still have negative camber even then. After getting the camber as good as possible you need the rear tracking set anyway. When I checked mine one rear camber adjuster was already at the max and one midway. On the front I guess shims behind the top link mounts would go some way to restoring camber if springs or bushes sagged. I'm having a crack at fitting Nismo bushes in the top links in front at the weekend and then I'll re check tracking again.

Since we're a picky shower of bar-stewards here and since you gave us so many piccys to look at - your bonnet or centre panel looks squint on 03.jpg! the gap is uneven - prolly the centre panel not put back straight after a mess around with the intake filter.

Sending one down to the stores for a long stand! I've been got with a message to call a Mr Lyon at a number that was the local zoo or a Mr Rose at a number that was the botanic gardens. But most irritating was a week where I had to shout down the phone all week to be heard due to a piece of cardboard inserted into the microphone part of my phone. All a long time ago of course when I was wetter behind the ears. However I got my own back on one of my torturers when he took a call at my desk - the end of his tie was in my partially open drawer so I shut it gently. He near strangled himself when the call was finished much to the delight of our colleagues.

So how long before we see 20" with 275/25 by 20" then? Also are bigger diameter wheels not fundamentally heavier? and does it matter?

Could imagine the manual chip doesnt have the routine in it to retard the timing on upshifts to soften the gearchange so maybe it wont feel as smooth on gearchanges but cant think anything else is so affected that it wouldnt work at all. Not sure but doesnt the auto ecu talk to the engine ecu to do this. Still the different turbos and camshafts must change the tuning characteristics auto/manual a bit but maybe not as much as people think.

http://www.300zx.cl/ Some good stuff here for zed addicts that I havent seen before anyway- sales brochure, road tests, drawings, cutways, videos and sound files etc - you can waste hours browsing it! asta la vista baybee the zed consiousness grows ever larger

Not reconnected the wheel sensor maybe or wiring to it or possibly damaged the reluctor ( I think thats what its called) ring on the hub when changing the bearing. VW wanted to relieve my bro of a grand for a new ABS unit until he spotted the wire to the wheel sensor was frayed through.
