It looks very original and unmolested, even the original bag for the jack looks to be there.

Not really enough information to be sure what your query is tbh.

The VIN certainly appears to be a bit of an anomaly - the code letter for the engine (eighth letter - G) gives it as a 1.8 non-VVC (120), but the code letter for the transmission (ninth letter - B) is for a 1600 Manual (115). As it is a Rover Australia VIN plate (rather than a Rover Group one fitted at Longbridge), I wonder if someone has made a mistake when punching the VIN sequence onto the Australian plate? or was the Australia market 120 fitted with the 115 ratio gearbox? Does the VIN on the plate match the VIN stamped into the bodyshell? (should be to the rear of where the VIN plate is fitted I think), and the one which should be visible through the bottom corner of the windscreen?

You could try entering the full VIN (without the first three letters) into the relevant page on www.mg-rover.info - this should tell you what the car was entered on the build records as (if the VIN is correct).

Looks pretty good for a car parked outside in Perth for a number of years.
Would advise you to have the head gasket checked before buying, not that that is a deal breaker, but you can use it as a negotiating tool.
There are a couple of good specialists in the Perth area, pm me if you would like details.

it has the VVC engine, cant see the gear box ID plate, every thing about it looks like a 1.8 non VVC

the miss is on number 1 and 2 cylinder
there is no spark
as the spark is on these cylinders is supplied from two different coil packs i am at a loss
i would have thought if the coil pack was faulty it wouldn't work at all, yet half of each coil pack is working

i thought there might have been a member who might have been able to suggest some thing regarding the no spark problem

I don't have a VVC, but could it be that you put the new spark plug leads on the wrong coil pack?

As I’m sure you know each coil pack feeds 2 cylinders. One for cylinders 1 and 4 and the other for 2 and 3. This type of system works on the wasted spark principle, with each coil pack firing once per revolution, with both plugs attached to the coil pack sparking at the same time. One plug ignites the compressed mixture, while the other fires at the end of the exhaust stroke doing nothing and hence this is a wasted spark.

Unlike a conventional coil where one end of the coil is connected to chassis and the other end feeds the spark plug via the rotor arm, in a wasted spark system each end of the HT coil is connected to a spark plug. Therefore for 1 plug to spark so must the other one. The only way one plug can spark without its counterpart also sparking is for the high voltage to find its way to ground (chassis) via another path. This could either be internally to the coil pack or via the plug lead or plug connection breaking down. It would also be possible for a plug to fail or be fouled.

As your problem is on cylinder 1 and 2, with cylinder 1 being fed directly from the coil pack and cylinder 2 is fed by a plug lead from the other coil pack, you should be able to use a process of elimination to find where the problem is. First I’d swap the complete coil pack and plug leads around. Doing this should move the problem to cylinder 3 and 4. If this is the case I’d leave the coil pack where they are and swap the plug leads. If the problem now moves to 2 and 3, the issue is with the coil pack on 3 and the plug lead on 2.

If you do this mark the leads and coils before you start otherwise you’ll get confused.

well i swapped the leads, no change
so i swapped no 1 and 2 with the old leads and it runs like a clock

well, I bought the leads from Rimmer Bros and they sent me a new set, no trouble at all.
as this has been parked for a number of years, I want to change the timing belts.
I have watched some vids on you-tube and they are only on the none VVC engins.
I removed the timing belt cover, right hand side and found the timing marks are different to the ones I saw on the vids, so I need a engine manual.
any idea where I will get one ???
also any advice would be welcome
thanks
