What follows may apply only to earler RV8 systems, but whatever ever the actual cause of RV8 overheating, these ideas may help? # Crud in the cooling system - flush and reverse flush the three main system elements, separately - Block, Heater matrix and Radiator - using domestic water pressure...

Oh Well! And there's me thinking that because the white/black wire from coil negative to pin 1 ECU was not on your concise checklist, that must have been missing and it would have precisely accounted for the symptoms too. I'll go backto sleep now, causes less confusion all around. Apologies Ramon

Hello Brian, You are missing the ECU trigger signal from coil negative to pin 1 of the ECU via a 6800 ohm resistor on a White/Black wire, explained here: Rover SD1 Efi Trigger Resistor Homer Simpson had a word for this: DOH! My cct diagram shows how: Check out the other Efi component...

Hello Rob, Check under carpets, boot, anywhere for the on-board swimming pool. Soak it all up with newspapers, towels, sponges, etc. Why fogging up at 15/1600 hours? Parked outside, solar heating (sunshine or no sunshine) warms up the car interior and the swimming pool evaporates converting...

Might be worth testing the viscous fan coupling to see if is faulty before buying a new one. This extract from my article on Viscous couplings # The first of two common fail conditions is when the fan does not speed up due to insufficient bond between the wheel and the housing resulting in...

Hello Dan, If you definitely saw the jet of water coming from the rubber pipe, then its probably also dripping upon the top of the rocker cover when the pressure is lower and you coincidently observed the coolant bubbling/boiling off where it runs onto the very hot cylinder head/block as it...

How wierd, no info as to the type of engine, fuel system or fuel? You have to provide more clues. I guess its a flapper, running on petrol and lpg and because its a temperature related fault, it is running too rich after it warms up. So the Coolant Temp Sensor or its connections are open...

Hello Arni, Its not clear to me whether your car is faulty or if the battery might be toast. Assuming the latter, you may want to consider testing it, which is possible with a simple multimeter and loading the battery with the lights and other electrical items on the car. All you need to...

Hello Gunny, You have probably developed a rogue air leak into the plenum, and this compromises the mixture below a sustainable ratio as the engine gets hot and the temp sensor stops any cold running enrichment. Your '88 system will be similar to the SD1 in many respects and you can find a...

hello fanatic, a 100ah battery will only deliver 100ah when its fully charged. 30 amps does seem a bit high for the items you mention being switched on, except perhaps you have got uprated h/l bulbs for example, and other items drawing power which have escaped your notice. so its a...

Dab some of the clear fluid up with a tissue. Set light to the tissue. If the tissue burns away including the fluid, its oil or fuel If the damp part of the tissue wont burn, its water If its water, and its clear, its condensation from the air conditioning system coming off the...

I noticed the phenomenom you describe recently and put it down to the same reason - fluid being trapped in the viscous when the car is parked up hot, and taking its time to disperse when next started. - usually less than a couple of minutes though. Also pressing a rolled newspaper against it...

Hello Smithy, Normally the viscous fan coupling turns at low speed induced by relatively low coupling forces between the housings. These extracts from my essay on them explains how and why they fail: "Viscous Fan Coupling (Clutch Fan) uses the unique properties of a silicone oil whose...

Hello Sean, Dont I know you from somewhere? I dont think I had your prior suggestion in mind when I made my observation, so, No! The point was to advise a person unfamiliar with agricultural suppliers who generally shops at normal Automotive outlets to purchase the best battery he can afford...

Hello Karl, First of all I had the temerity to wander into a diesel universe with tips to solve a Rover V8 problem, so I cant add much to you personal experience other than the observation regarding expelling all the air would be desirable.. I would not rely on the coolant system capacity...

Hello Rocky, you are not getting all the air out of the cooling system and this explains the excessive pressure as the water boils and you get all the voids filled with superheated steam. Folks have many methods of getting rid of air locks, find one that works and stick to it. Mine is...

Hello Vinny, Ignore any trolls and read the PDF from here to understand why Only the Rich can afford Cheap Batteries and then buy the best battery you can afford. On the other hand buy the cheapest battery you can get and check back in a years time for a re-read of the essay.

An engine idling off load at excessive rpm when put into gear, has to start turning the transmission torque convertor which in turn wants to get the car to move. - not easy from a dead stop with all that tonnage requiring forward motion. so the engine speed drops until the TC can get going. in...

Sorry Reg, you got me there, but I dont think its the same plenum. That name (plenum) also applies to any air reservoir and I reckon the one you identified is the one prior to the cabin air intake system. I've got a cabin intake "plenum chamber" on my car too. You need to get familiar with the...
