|The Rosdi Oil System|
The Rover SD1 camshaft & valve gear protection.
It is well known in motoring circles that Rover 2300 and 2600 SDI cars, produced between 1975 and 1987, all too frequently suffer from an expensive engine failure in the lubrication system a crucial problem for a fine car.
THE PROBLEM IS BASIC: TO THE ENGINE ITSELF: SIMPLY REPLACING COMPONENTS OR EVEN FITTING A MODIFIED HEAD DOES NOT BRING ABOUT A CURE, AND THE VULNERABILITY IS STILL PRESENT.
Who Cares? You should!!
The full cam carrier assembly alone costs over £500, and repair necessitatas complete disassembly, rebuild and the difficult resetting of the overhead camshaft and valve gear, together with the removal of the cylinder head to check for valve and piston damage so that, with labour, the overall repair cost is frequently in excess of £ 1000. If a new head is required, this would cost around an additional £600, so the better option might be a replacement engine-but this costs around £1200 (plus £120 if your own engine is damaged) plus more labour. Don't forget also that VAT must be added to these figures! Even if you bought secondhand parts and fitted them yourself, it would still cost several hundred pounds.
After all that, you still have a vulnerable engine wher the same thing could happen again!
So, what do you do? Bury your head in the sand and hope it never happens to you? Join the many who have lived to regret THAT decision!
But, you say, your car is "getting on a bit" so you'll throw it away if you get the trouble. Think Again; you probably bought the ROVER because there was no other comparable car available at such an attractive price, so you'll have to buy another and face the same risks again or pay more for something else that's not as good. It's still going to cost hundreds - in fact, even with a geriatric vehicle, you're probably nearing the £1000 figure again if you count what you're throwing away.
Sell it , perhaps for a decent price, hoping others are unaware of the problem? But they probably are that's why such a desirable vehicle without a ROSDI costs so little. If you are one of the lucky ones and are the proud owner of a later Rover worth several thousand pounds, you should need no persuasion to fit ROSDI protection.
Perhaps you've always wanted a Rover, looking longingly at the comfort and luxury of a Vanden Plas model, realizing what a good buy it would be if you weren't so worried by those dark tales of camshaft failures. Now you can buy it but, whatever you do, make sure it has a ROSDI or fu one yourself.
Some appointed garages are happy to discuss the problem, usually emphasising the dangers of poor maintenance. Non-attached garages, on-the-road servicemen and motoring organisation personnel are often more critical. Perhaps one should bear in mind the profits gained by selling expensive spare parts!
If you are one of the unfortunates who have had the problem, you'll now be wishing the ROSDI devices had been available earlier or that you'd fitted one when you first heard about them. If the car is still laid up, regrettably we can't do anything for you to avoid buying those costly spares - but at least you know what you must do as soon as the repairs are completed.
The solution is simple, despite the apparent inaccessibility of the lubrication passages leading to the camshaft and valve gear; these lie mainly beyond intervening cavities in the block, head or cam carrier. This also prevents routine checking of their condition during normal maintenance or even with new components fitted following an expensive failure (when serious lubrication system contamination is known to have been present which could easily give rise to Repetitive failures through the same cause).
Rosdi units and what they do
ROSDIWATCH: gives immediate warning of valve gear lubrication supply failure, enabling engine shut-down to PREVENT HUNDREDS OF POUNDS' WORTH OF DAMAGE. The sensing system operates completely separately from the normal engine oil warning light system, since this and the pump can be functioning perfectly and yet the camshaft and valve gear can be on the point of seizure.
