My car runs totally brilliant, no smoke nothing, making good power but obviously we knew something was wrong. Anyway i bought a leakdown tester to see exactly where its losing pressure and whats needed to rebuild it back to 100% Was a real eye opener did a compression test first and all were 160 psi with the engine being cold but number 4 was at 90 odd so i knew that something was wrong there anyway but then we did the leak test and 1,2,3 were all perfect no valve leaks, ring leaks, headgasket leaks etc, did number 4 and we expected a bad result and as we expected went straight down into the red and you listen to where the leak is coming from. Oil cap and i…

I have a problem with the speedo in my '92 UK spec 300ZX auto, it suddenly dropped to zero shortly into my journey, flicked back up to show the correct speed a couple of times before dropping down to zero & staying there permanent. Without the speedo the power steering cuts out after a short time & the HICAS lamp comes on. I have replaced the speed sensor on the auto gear box to no avail & tried a new speedo unit to no avial. Last weekend I jacked the rear of the car up & measured the ac voltage out of the sensor whilst in gear, ranged from about 1v rms to 3v rms depending on speed. Checked I was getting the same out of the 2 pins on the connector tha…

Thinking of uprating the suspension but do i need to buy new poly bushes also? Can i just buy uprated and lower springs as mine does sit a little high? Also budget tight so nothing too pricey? Ta

My Dad saw 2 black Zeds either Sat or Sunday together, think he said Ipswich road. I also saw a red one coming Towards Dunston Hall.

who's is the red Z been parked outside Autotune in Hedge end for ages now... (Got like checker'd flag design on it....) just wonderin if its like got something major wrong wif it... (been there for at least 2 weeks now...) :( Plate starts with ROB so rob, i take it its u..... but the question is..... who is rob? :) :dance:

As the engine is out it makes sence to rebuild the engine but what is actually needed? i want to hold big hp, the tubs which are on order should hold between 550-600bhp ish. I know the obvious parts which need replacing but what about other bits. I've been looking on sites do i need to replace any of the following? Valve Springs Titanium Retainers Valve Guides Crankshaft Master Valves

currently i have Dump valves on the turbo pipes at the top of the engine. If i was to remove these and connect the standered wastegates back up would it make the cool wastegate sound rather than the dump valve noise? Also what are the best? My brother done this on his 200sx and his wastgates sound awesome and they are standered.

Bright red zed on a drive in the same cul de sac my mate lives on :)

Done a search on this and seems as usual there is a problem with camber when lowering . Adjustables sort this! Problem is mine is standard ride height,standard rims and is running bad negative camber to the point were the inner 60mm of the tyres are slicking out with thousands of miles left on the rest of them. I know it can run out with age and a mechanic friend has suggested that if it is original front shockes and springs they may just be knackered and causing the problem. Anyone think this is correct or is there a more sinister problem going on?

Saw you today, well think it was you! Had the stripes on the bonnet like you have!

Saw you on Friday afternoon (2 June) heading towards Ipswich. I was heading th other way in my dirty Zed! :p

You had a big wing and loud exhausts. Looking good! I was in the white one with black tape on the bumper.

Silver Z 4exhausts near BP hounslow west heading towards Feltham went round the roundabout twice, Z moved very quick must say sounded good too. We was parked up in BP red Z and Purple/Blue Z Yesterday.

ive got a set of bilstein shocks on the front an on one the bottom bush has gone the shocks part number is 636 1481 h001 would i be able to get a new bush or have i gotta get a new shock?

Anybody know who supplies the series 1 replacement spoiler the cheapest. Got a price of £175 but sure i saw them for £125 some were?

My water pump has just gone pop,shit and steam everywere. Hope i have not cooked it. Got off the road and switched it off asap. Anybody had one replaced and how much did it cost? Mine is an NA so not sure if it is the same as the tt or maybe maxima?

you was talking to a friend of mine called stu

Finally seen another one. Pulled up next to a silver Z in the Stirling Services, I was on the CBR though :xxx: . It was a G reg, looked and sounded in very good condition. Dave G

Stupid question probably. Are these all diifferent so that I can check the correct engine is in my car or do they just indicate the engine type ie.twin turbo or NA etc. Also where is it to be found I don't have my car at the mo but will be checking it on tuesday. Sorry if this is genuinely silly!! Rob

red zed heading down orton road carlisle at 10.30am this morning. i was in mine and waved but just got blanked :cry: also...silver zed heading towards keswick (lake district) 1pm ish again i waved and nothing back!!

Hi all, Very strange.... when driving normally, there's been no problem(autobox), however when leaving the car on idle for about 5 minutes or more the exhaust starts bellowing out smoke. :( Any ideas? Could this be a turbo seal going or something much worse? (my motor has covered about 75k...) Of course I'll be getting it checked out shortly but wondered if anyone else had this happen? :rolleyes: cheers, Quadsmarty!

Well this bloody Z is starting to take the mick Windows working fine yesterday got in it today (very hot day) and my window would not go down? Any ideas, I cant see it being the switch and I doubt there is a fuse per window? It makes a very quiet clicking noise when you press the button but that could be the motor or the button lol

Where is this in the engine bay, I want to remove the hose from the solenoid to check if it's working at all, but have no idea where it is. Ta.
