The V8 Owners Forum -

Thanks Stevie.

I can see that could be part of my solution.

Dave, you are right.

Currently I have an intermittent faulty unit in the car and several spares with the wrong gear wheel (pinion).

If I can swap my existing pinion on to one of my spare units, I can solve the problem.

If not I could ...

Circa 2010 - 2012.

Does any one recall a V8 Forum Member posting about swapping pinions on the LT77 Speedo Transducer?

The gentleman concerned must have established a method of removing the pinion without damage and exchanging different color pinions to suit his need.

I think he also sold ...

Many thanks, I was talking to someone who thinks
That my valve rings( is that correct term) may be gone as even
Though I have decent compression and good vacuum , I get some
Smoke going into the air filter from the engine, my car idles differently with pancake air filter off to when on , is this ...

Hello mrsimsam,

It varies, of course, with compression ratio and altitude.

In your case 10.5 CR multiplied by 14.7 lbs/sq inch atmospheric pressure (say, near the seaside, approx) = 154 psi.

Take off a bit (up to, say, 10%) for reasonable losses around the rings, valves and what the cam is doing ...

Thanks. Most interesting.

I removed the stat and the problem vanished. I removed it because it was also opening late, and by the time it did, the fan switch didn't have time to catch up and didn't kick in until 100.

Now its coming in at 90 and I've gained a few degrees.


You'll probably be ...

I believe what happens is this:

Air pockets get dragged around the cooling system randomly according to the speed of water flow. ie related to engine rpm.

When one of the pockets of air pass by the exhaust manifold water galleries (by far the hottest locality) the coolant thereabouts turns to ...

What makes a spark plug just give up like that? Was fine this morning. They must only have done about 3K.

Hello Bart,

Perhaps half a dozen reasons why a new spark plug will fail prematurely.

# damage to electrodes when ...

Hello ?.

I guess is depends upon your use! Urban? Long haul Motorway? Track?

For normal urban motoring you will definitely be able to do all you need with 95 RON.

Don't thrash it and don't overload it. Let it rev freely and change your engine oil every 3000 to 6000 miles according to how it looks ...

Hello Richard,

In general the original (shall we say) SD1 V8 set-up of cabin heater, radiator, thermostat, cowelled viscous fan and Aux fans - if fitted - is perfectly capable of overcooling the engine.

It is the responsibility of the thermostat and the viscous fan to, jointly, control the ...

You could add molyslip!

as per pages 3 & 4 of the pdf available from here:

If that does not work, check and renew if necessary the rubber bushes of the 'remote' assembly.

Hello Mick,

Its a while since I worked on mine and my memory fails me.

However from this link on my web site there are two LT77 PDF Workshop Manuals for download.

Hi all

I've had a couple of "fail to starts" recently when the car has been sitting for 10 minutes or so after a long run ,

Are you just presuming that the ignition amplifier is faulty or have you proved it by observing nil sparks at the king lead immediately upon opening the bonnet?

What if it ...

Very interesting and I can report it will not tick over unaided by the throttle but as it's in the garage I cannot hang around without suffering from c02 poisoning.

Orange can you clarify this?

The statement confuses me if the engine will not tick over - otherwise you could stay in the garage ...

What is interesting it still starts and runs with throttle when the fuel pump relay is pulled and pump not working. Must be pulling fuel through.

First thing you need to do is check just what is happening with the fuel pump - as it certainly can't 'pull fuel through' with the pump stopped when ...

Almost immediately it started playing up going into a massive stuttering misfire when you tried to use anything more than half throttle. Sometimes it would behave itself though and drive perfectly - usually when hot.

I've replaced the ignition amp and ecu temp sensor - but the car was almost ...
