Hi folks. After my rrc not starting i replaced the dizzy cap and everything was running fine. Then yesterday it just stopped got it started again but wasnt ticking over properly had to keep revs up then died miserably .Also the coolant tank is pressurised even by just turn over the engine if you undo the cap coolant f@cks out. I thought HG

Now the B@sterd thing wont even fire. Turns over and now and again it coughs and thats it. I was advised on replacing the module on the side of the dizzy or the coil. Can i replace the module without taking the whole dizzy out. Any advice would be great thanks.
 
Did you have any over heating or coolant loss before it died? Or any problem with your heater blowing cold air when it should be hot?

Check your oil for signs of coolant contamination, it'll look like spoiled mayonnaise on the dipstick.

After that you've got to start figuring out if it's not running because of fuel, air or spark.
 
Checked dipstick all looks normal, heater does give out heat. Did take spark plug out yesterday and there was a spark but not great. Could the head gasket stop it from firing. It hasnt devoloped any nasty misfires and the temp gauge has always been normal
Cheers
 
Soz. I know nothing of lpg systems. I live in the land of milk and gasoline.:D

The spark should be bright white not yellowish. When mine suffered a similar issue, it turned out to be the coil.
 
:) your not the only one. The spark was yellow and did look weak. If it is the head gasket could that stop it from firing. I did have a peugoet once and the head gasket went but it still kept going. Cheers
I've not suffered a HGF, so I don't know. I would think that if it were catastrophic enough to keep it from firing then you would see some other signs, like lost coolant. Have you checked other plugs? I recollect from other threads here that a plug that looks all steamed cleaned and bright can be a sign of a HGF or cracked liner.

I did only check the one plug. It doesnt seem to lose coolant just built up pressure even just turning it over. Could it be i over filled the coolant tank. I always thought HG causes serious misfire/power loss which it seems to be fine in that department. In the peugoet i had that used to **** out water every where. I was told by the recovery bloke last night that it could be the thermostat not opening/closing.

Sounds like you might have a couple of issues there mate. I have had a quick blast through this thread, I would suggest check ignition system. What year and what engine is it? 3.5 flapper or 3.9 hotwire or maybe 4.2 if it's an LSE.

Try a search of V8 section for ignition checks/tests. Could be a failing coil or possibly ignition amplifier.

Yes it is possible to remove amplifier without removing distributor but it is fiddly and you will still have to time it up after.

Pressurising cooling system is classic symptom of head gasket failure, do a compression test straight away. If you don't know how, again do a search ( I know I've posted on that).

AFAIK a slightly blowing head gasket won't stop it running but if it is a big leak then there will be a loss of power and possibly little or no combustion if cylinder pressures are really low, min. on a V8 is about 150 PSI, and between 170 - 180 on a healthy 3.9.

You said something about having to keep revs up then it just died - could be an air leak, check inlet pipework and all vac pipes.
 
Thanks for info C Kev. There didnt seem to be any power loss when working. When turning it over now though there doesnt seem to be much oomph as there was before (battery is ok :D). Is the HG a big job as iv only changed HG on motorbikes. Wouldnt mind doing it myself to keep costs down and to get a bit of know how.
 
Could i have a liner slipped/cracked as spoke to local garage who told me 3.5 and 3.9's were bullet proof i.e no liner problems but i thought that was just 3.5's. He also said if it was a liner then me engine is shagged. Can you get replacment liners or has it got to be a whole new block. cheers
 
3.9s are prone to liner probs..you are correct only 3.5 is bullet proof..

cheaper to go buy new engine than repair...to wit i have an excellent tuned 3.9 i would sell to fund my big yanky v8 hunt..london..pallet service is cheap..
 
How much you looking for Zen. Im hoping that it is just the HG. Is this a big job as would like to do it meself to keep costs down. Just had a look at the beasty and there is slimey/sludgey stuff in the coolant tank so im guessing its HG.

In fact any of the 94mm bore RV8's (3.9/4.0/4.2/4.6) are prone to slipped liners. (With hindsight LR would have probably been wiser to just extend the stroke when seeking more grunt back in the late eighties). I've suffered head gasket failure myself on a 3.5 & a slipped liner on a 3.9, but neither prevented the engine from starting/running.
