MG RV8 Owners Tips
As the kilometres of our RV8's increase and the cars start to age (the youngest now being at least 25 years old) it is very important to share any information we have about our vehicles. Set out below are a few problems which have started to appear in the UK and no doubt will effect some Australian owners in the future.
As an obsessed RV8 owner I am continually searching for and gathering MG RV8 information, which I would now like to share with all fellow RV8 owners.
SUPPORT FOR RV8 ENTHUSIASTS FROM THE V8 REGISTER - MG CAR CLUB
From the launch of the MG RV8, the V8 Register of the MG Car Club has actively supported the RV8 and has produced a series of helpful service & maintenance notes with spares tips. The series has become very popular with RV8 Enthusiasts in the UK and overseas, and has just reached Note 258 in Volume 8.
Complete sets of the RV8 Workshop Note Series are available on CD in Word & PDF Formats.
Details of how to obtain copies of the Workshop Volumes, each with a comprehensive index and how to join the V8 Register can be obtained from the V8 Registrar, Victor Smith, at email@example.com or by Fax on +44 208 392 9673
The V8 Register was formed in 1978 by a group of MGBGTV8 Enthusiasts and has become the leading group for MGV8 Enthusiasts. The group includes MGBGTV8's, MGBV8 Conversions, Costello MGBV8's and MG RV8's with over 2800 members in the UK, Australia, New Zealand, Japan, South Africa, and across mainland Europe.
It is a group any MGV8 Enthusiast Should Join !
PROBLEM TIPS FOR RV8 OWNERS:
RV8's RE-IMPORTED FROM JAPAN:
It has been found all Ex-Japanese vehicles have their distributor vacuum advance pipes coming from the side of the plenim chamber.
This is seriously wrong as it causes constant vacuum to the distributor which inturn causes the timing to be fully advanced all the time.
To correct this the distributor vacuum tube is moved upstream to the nipple on top of the throttle butterfly chamber and the tee piece on the side of the
plenim chamber is then blocked off with the rubber cap from the butterfly chamber nipple or the Tee piece can be removed completely and the vacuum hose connected directly to the side of the plenim chamber.
After this conversion (which takes less than 5 minutes) the timing will now only advance when the throttle is opened.
Note: The first time the car is started after this procedure a brief automatic readjustment of the ECU will be noticed but this will then settle down quickly.
However if the ECU can not readjust to new vacuum advanced setup the timing will need to be reset, usually a few degrees before BTDC.

Workshop manual is a must for all RV8 owners and invaluable when working on your RV8. Clive Wheatley http://www.mgv8parts.com has reproduced the original workshop manual (hard copy) price £45.95 (GBP).
(NB. Clive Wheatley has invested an enormous amount of time and money into providing RV8 spare parts and we should all support him)
WIPER BLADE ADJUSTMENT:
Check the adjustment of your blades to ensure that the bottom corners do not interfere with the lower edge of the glazing rubber, the later being softer will end up with unsightly groves worn in it where the blade catches. (Bryan Ditchman's Tip).
CLUTCH MASTER CYLINDER CAP:
Removal of the clutch master cylinder cap can sometimes be very difficult, resulting in skinned knuckles or having to resort to the use of grips which will inturn deform the soft aluminium cap. For easy removal, invest in a "Zyliss Strongboy Jar & Bottle Opener" (definitely a recommended RV8 tool kit addition). (Bryan Ditchman's Tip).
DISTRIBUTOR CLAMP WRENCH:
For all those who have adjusted the timing on your RV8, you will have noted how difficult it is to reach (undo & tighten) the distributor clamp nut.
This operation requires a special Rover service tool, but there are other substitutes at a fraction of the price. This wrench with its special shaped long neck makes the job so much easier.
Below is a picture of the wrench I picked up for $35 Australian Dollars. The wrench is made by MECO and available in Australia through the Repco automotive stores.
PLASTIC COOLANT FILLER PLUG CORROSION
There has been a recent warning from the U.K. V8 Register to be aware the coolant filler plugs are corroding and causing coolant leaks. The plug in question is the black hexagonal plastic plug at the end of the high rise pipe used to fill the coolant system. The RV8 workshop notes 150 and 158 both cover this item and recommend replacement. The plug is the same as that used on the range rover. Original part number ARA240 but some suppliers supersede to KTP9401. ( UK V8 register workshop notes tip. )
Almost all RV8's have the dreaded alloy wheel corrosion. The only answer to this problem is a total wheel refurbishment. This requires the removal of tyres, valves and all studs. Refurbishment costs around 50 Pounds Sterling or $120 Australian ( or slightly less if the hub covers are not included) (Bryan Ditchman's Tip).
It has been found there is a small hole drilled at the lowest point in each exhaust pipe, between the silencer boxes. These holes become blocked up and require regular cleaning with a 1/8" drill bit. (Bryan Ditchman's tip).
EXHAUST MANIFOLD NUTS:
A regular check of the exhaust manifold nuts should be carried out as they have a habit of working loose. (Be careful not to damage Studs/Nuts through over tightening)
WINDSCREEN SURROUND CORROSION:
A windscreen rust problem has surfaced on some RV8's ( mostly those continually exposed to the elements ) ROVER UK have replaced these surrounds under warranty, if the problem occurred within the Warranty Period. The rust seems to mostly appear along the bottom rail. To help prevent this it is suggested applying a rust inhibitor (ie, fish oil) (odourless of course) between the windscreen glass and the rubber seal. The windscreen rubber can easily be lifted away from the windscreen glass with a screwdriver blade (however ensure the edges of the blade are nicely rounded and not sharp) the fish oil can then be sprayed into the crevice with the aid of a spray nozzle extension. Hopefully this will prevent moisture trapped between the windscreen rubber and surround from causing corrosion.
AREAS OF RUST & CORROSION:
The following areas have been found to be susceptible to rust and corrosion. In identifying these areas we must remember all Ex-Japanese RV8's have endured lengthy sea trips to and from Japan. Thus many RV8's shipped to and from Japan have covered more miles / kilometres on a boat than they have travelled on land. The significant exposure to salt air is one sure way to find corrosion weaknesses. The areas identified below are mostly small items and not major body panels ( ie wings sills etc ) as the body panels are all zinc coated. If corrosion is found or suspected it is recommended the effected areas be immediately treated and followed by a full rust prevention service.
* Front cross member
* Front header rail retaining strip on the hood
* Exhaust mounting hooks and brackets
* Expansion tank mounting bracket
* Top of petrol tank and sender unit
* Sill mounting brackets
* Rear hood surround under the rear screen
* Windscreen frame in general
* Inlet manifold gasket
* Headlamp retaining clips
* Starter motor terminals
* Alternator main terminals
* Bottom of heater box
* Hood frame pivot points
(Bryan Ditchman & Roger Parker tip)
NB. United Kingdom & European weather conditions are far more severe on motor vehicles than Australia's hotter and drier climatic conditions and tend to accelerate these corrosive problems. (ie. there is no salt laid on Australian roads)
RV8 ALARM SYSTEM REMOTE:
Needs watching, as there is no central locking system deactivated with a key, so if the transmitter is lost or stops working the system can only be deactivated with another correctly programmed remote.
So remember to renew batteries in the transmitter annually and keep spare batteries in the glove box. (Ron Armstrong tip)
All RV8's fitted with air conditioning should have the system run once a week for a few minutes to ensure the refrigerant fully circulates through the system. Failure to carry out this simple operation can and often leads to a failed air conditioning system. (Roger Parker tip)
RECOMMENDED FUEL FOR AUSTRALIAN RV8'S
Shell V-Power is a new generation High Density High Octane petrol that will optimise the performance of your vehicle, making it more responsive by providing power more smoothly, more quickly. With an octane rating of 98 it has the highest octane level of any petrol available in Australia.
With a Research Octane Number of 98, Shell V-Power exceeds the requirements of Australian Standard AS1876 -1990 and Amendment 1 of 11 July 1994 for premium unleaded petrol. This high octane together with high density and a new formulation enables optimum engine efficiency, improved engine responsiveness and better fuel economy. This makes Shell V-Power the preferred fuel for use in modern high compression and knock-sensor vehicles.
SUMMARY OF BENEFITS
The unique cleansing properties of Shell V-Power premium unleaded petrol care for your car's engine - regardless of age. Built up carbon deposits on inlet valves are removed and fuel injector, or carburettor systems are also kept in clean and in peak condition allowing the car's engine work the way it was meant to. This improves performance by keeping clean fuel injectors, carburettors and inlet valves and leads to consistently good gasoline/air mixture preparation, better combustion and better driveability. The result is better fuel economy and reduced maintenance.
Shell V-Power can be used in all petrol applications. Where engines that require the use of Leaded Petrol to protect valve seats, Shell V-Power should either be used for two fills in three or a valve seat recession additive should be used with every fill of Shell V-Power. Shell V-Power is dispensed through a blue marked hose which has a small diameter nozzle.
HEALTH & SAFETY
Shell V-Power petrol is a highly flammable liquid, classified as a Dangerous Goods Class 3 Packaging Group I for transportation purposes. Avoid contact with the skin and eyes, and breathing vapours or mists.For further guidance on product health and safety refer to the appropriate Shell Material Safety Data Sheet.

Since changing to Shell V-Power my RV8 has never ran so well, almost immediately I noticed smoother idling and improved acceleration.
My economy figures have also improved about 5%.
K & N AIR FILTER SERVICING
1. PRE CLEANING PREPARATION: Gently brush all crevices with a soft brush
to dislodge any dirt, then gently tap the filter.
2. SPRAY ON CLEANER: Spray K&N air filter cleaner into entire element and let
soak for at least 10 minutes.
3. RINSE OFF: Rinse off element with low pressure water (tap water ok). Always
flush from inside to outside.
4. DRYING: Always dry filter naturally, after rinsing shake off excess water & let
element dry out naturally.
* Do not use compressed air
* Do not use open flame
* Do not use heat dryers
NB. Excess heat will shrink the cotton fibre & compressed air will tear or blow holes in the element fibre.
5. CLEANING HINTS: Because elements are so expensive to replace ($120).
* No petrol to be used for cleaning
* No steam cleaning
* No caustic cleaning solutions
* No strong detergents
* No high pressure cleaning
* No cleaning solvents
Any of these products will cause damage to the cotton fibre filler plus hardening and shrinking the rubber end caps.
6. RE - OILING: When filter has thoroughly dried out naturally always use K&N
Air Filter Oil. The oil is sprayed down into each pleat, with one press per pleat.
On completion, wait 10 minutes and re-oil any spots you have missed.
A proper oiled filter will appear uniformally red in colour. Never use a K&N Air
Filter without oiling.
NB. K&N Filters are among the most expensive and when correctly cleaned will last for years and years. Skimping on the correct cleaning products can have serious consequences if the filter is ruined and requires replacement.
Some of the information contained in this section was gathered from the United Kingdom M.G. Car Club V8 Register publications. The articles were compiled and unselfishly shared by Bryan Ditchman, Roger Parker, Victor Smith and others for the benefit of all RV8 owners. Thank You.
NB. It is strongly recommended all RV8 owners should consider joining a MG
Car Club. Joining will entitle members to access the vast amount of
information available through the V8 Register. (ie. RV8 Workshop Notes
Series which are invaluable to any RV8 owner).
