V8 Compression Test

Lucas is the genuine rotor

There is one other possibility - the ignition module on the side of the dirtibutor - when it starts to fail it can cause misfiring etc - it mostly happens when thye car and temps are hot (the mod cooks in its location) however in my case it was the opposite - started to breakdown on minus temp mornings in Canberra and went on that for 5 years until it started playing up all the time irrespective of temperature - they are about $120 to replace.

Given the testing that you have done maybe it is time to take the car to a specialist :o

GOOD NEWS

I played around with the timing by ear(Iknow this is a no no to some ,but Im desperate)and found I got it to run and sound better.

Two things
1.I now need to buy a timing light for the fine adjustment.
2.Why would the timing go out if I have never touched it and the distributer wasnt loose?


Garry,I like the blokes at the LandRover dealership but there knowledge isnt quite the same as most others.The 2/3 guys there,there is only one tradesman and the others are apprentices and both havent been there that long around landies.

Ive asked them for help ,which they have given but I have gotten more help from the people in this web site in 1 week then what I have in 1 year from them.


So a big thanks to all that tried to help me


Thanks

check the vaccuum advance unit on the side of the dizzy.....
if the diaphragm has a hole in it it wont advance properly.....

the motor will often idle smoother if the timing is out, but it rears it's ugly head at revs and under load.
get yourself a timing light and like any other landy V8 owner, keep it in the car. mine lives in the under-seat box on the drivers side with my dwell meter.
they do wander a bit, don't know why, they shouldn't but they just do.
26deg BTDC.
have fun and don't get your 9/16 spanner caught in the fan

They most certainly do - Landrover specialists were trying to sell me new distributors from when my disco was 20,000 km old to when I sold it at 100,000 km - when on the tune up machine the distributor was all over the shop - yet I was always able to time it with a light without any problem so it ran OK - at least with a new ignition module.

Another thought. You might have one or both of the mechanical advance springs broken or detached if changing the timing made a difference. I had a bugger of a time with the dizzy on my Disco after whomever the previous owner used to service the thing failed to put oil on the dizzy shaft prior to fitting the rotor. It was jammed solid, I pulled on it the two parts of the shaft seperated. This unhooked the weights and springs and allowed a massive amount of play. I had to remove, strip and rebuild the dizzy. After that experience I too carry a timing light in the car. Always!

Ok I need to get a timing light ,will do tomorrow.

But I have another question for ya's
Im getting a constant spray of water/moisture coming from my exhaust.With finding this I took the plug out of the radiator and noticed I get bubbles when I bring the revs up a little bit.(*note the radiator tank was not completely full about 1/2inche from the top and I get no bubbles on idlethat I can see)


Ill be booking my Disco into a workshop asap but just wanted ur thoughts
