The V8 Owners Forum -

Just like to say chaps a new pressure switch and fresh duckhams today and shes sweet as a nut.

Examined the oil that was drained was very black, well past its sell by date but no metal swarfing so im guessing it never lost pressure.

Again thanks for the advice

Thanks for the advice chaps ill look into it tommorow. Hopefully it wont be too serious, fresh oil, pressure switch and a new relief valve. Fingers crossed this should get it sorted. Ill post up how i get on. At what pressure would the switch illuminate the light then ? Just a little worried that i ...

Mines definatly not a serpentine engine. The oil does look fairly black so im going to change that tommorow.

I think ill change the pressure switch and the pressure relief valve too and see what happens.

Surely if there was no oil pressure at all the lifters would be very noisy ?

The oil pressure light illuminated whilst i was driving home last night in my 1990 range rover 3.9. I stopped as soon as i could, checked oil level all seemed ok. Restarted engine sounds fine no loud rattles etc. I then removed the filler cap and there doesnt seem to be a great deal of oil around th...

Thanks for the advice mate found the rpm trigger wire hanging down the inner wing connected her up and bobs your uncle shes all sorted

Ive inherited myself with a job today just after a few pointers for when i take a look tomorrow. Its a gas converted range rover, apparantly since a garage has replaced the coil the car no longer switches to lpg. Im guessing either the wires are mixed up on the coil or not been refitted at all ? Can...

You say in the ignition post that you run a wideband lambda system. Where did you get it from mate ? What sort of cash are these and are they difficult to fit. Have considered fitting a loop control lambda system for the lpg but they aint cheap. Also seen some vacuum operated mixture control setups ...

Backed it off a fraction today. im running 10 degrees static now no pinking issues on petrol and still pulls well on gas. Ive go a couple of intermittant problem when running on gas. Just cant seem to get to the bottom of them. Occasionally when the car hits 3000 rpm it just hits a massive flat spot...

Whats the best timing setting to use for my lpg ed 1990 3.9. I want a compromise so it will run as best as possible on gas but still drivable on petrol.

Checked today its got 14 degrees static with the vac pipe disconnected. Runs well on gas but pinks on petrol.

Been having a few running problems the last couple of days.

Intermittantly my v8 will pop back through the inlet whilst running on gas.

Guessing its ignition related but my coil is new lucas, new bosch plugs cap and rotor look in good condition.

Thinking about renewing the plugs, leads, cap and rotor on my 3.9 range rover. Apparantly improving ignition system on lpg equipped cars improve economy and performance. lpg very dependant on ignition being in tip top condition. What plugs are best to use ? (make,heat range grade) Id love to buy a s...

ideally you need an oscilloscope to check the switching of the low tension circuit.

Im led to believe with lucas ignition systems - amps often fail, coils rarely fail.

Hi there chaps just thought id let you know after many swear words and slammed bonnets i finally decided to let an auto electrician have a poke at getting my car sparking. After a couple of hours several multimeters, osilloscopes and cups of tea he finally pinpointed the problem to be an incorrect a...

Ive fitted a 3 pin amp and used the adapter loom.

Can anyone tell me what the wiring colours are. Ive been told by the place i bought it from but just want to double check

Was running perfect before the wiring burnt out. Its wired exactly as it should be a company called simtek refurbed my loom and theve made a spot on job.

Ive tried disconnecting the feed to the ecu i think its only a reference wire for engine speed.
