Lexurf IV - The Second Coming

[Growler]

just a thought - i used those pattern o2 sensors - one lasted 3 weeks and the other died after 2 months.

the guys in the lexus dealers sold me 2 ngk ones for £80 - still working now. Not so sure on that one Gary, as when I took it to Vince's his OBD reader showed them up as faulty unless memory needs clearing down

also had a carbon brush disintegrate on one of rock autos delco dizzy caps after 400mls - changed them for bosch ones which are still working now.

maybe i'm just unlucky

Just waiting to get myself sorted and then I can take a proper look at things, although it would be handy to have the reader at home instead of in Wales. Getting a strong unburned petrol smell which is why Vince put his reader on the motor.

P.S. took myself to a private hospital and things are now moving on, but ###### expensive. Bupa won't cover previously existing problems

excellent news on the back situation

try clearing the ecu - they are probably old codes in the memory - the od light flashes like a normal surf if theres a fault. it was ok in the last 5-600 mls i did.

dunno about the fuel smell - never had that before

[Growler]

Cheers Gary will give it a try.

It's alive!

Running rough as a roughed up rough thing, but it is running.

It's making a strange noise too, video to follow.

[Albannach]

It sounds like the cam or distributor, any other ideas?

[BUSHWHACKER]

It's not the cams.
Does it rev OK? Is there a strong smell of petrol from the exhaust?

Plug leads fitted correctly?


The only thing I can think of that would make that noise is the fan belt idler pulley, the small one at the very top. The bearing dries out and it makes a noise very similar to that. I replace them as a matter of course on all the conversions now, the bearing can be knocked out of the pulley using a suitably sized socket.
I get the bearings from a local engineering parts supplier, they're around £6 each, much cheaper than £30 odd for a replacement pulley.

It doesn't rev well at all, it's only firing on a few cylinders though. Now that I have it started, I'll change all the ignition things and the injectors, I'll swap that bearing too.

Once all the bits are swapped over; I'll do the codes and see how things pan out.

Bearing part number: C6031

Could be rain water in the spark plug tubes if it's been standing for a long time.

Thanks Vince, I'll order a bearing tomorrow.

The plug holes are wet, I'll seal them better when I replace the plugs and leads.

[gary-r]

hehehe remember my bearing vince - it sounded like it had a blower under the bonnet

[Albannach]

It's dead again!

It ran the other day (Wednesday), rough as a rough thing, but it ran.

Today it's dead, turns over, but won't fire. Ah well...

Cold start injector...black wire snipped on the back of the ecu...perhaps try connecting that.

I re-joined that, I think. Is it the wire with STA on it?

I don't think it's fuel, I think it's electrical, I'll swap all the bits I have to swap (so I know it's all good) then try again.

[gwh200]

Two bare ended black wires. If you have connected them, try starting without Andy.

[gwh200]

That post I just posted is crap.

If you have rejoined the black cold start injector wires, disconnect them and try that.
