Hi all, quick question. Should I be putting additives in with the petrol of my 1982 landy.
Thanks, Simon.

Do you know the history of the vehicle? Is it a petrol S3 standard landy engine? If yes and if you have been driving around for years what's the performance like.An original '82 engine will not be capable of taking unleaded fuel. If you know it's original and unconverted for unleaded then the answer is yes you should use an additive. Long term solution is to get the cylinder head re-done. Costs around £300-400.

I'd not bother. If you aren't doing big mileage it'll take years and years and years to wear the valve seats. The cost of additive just doesn't make sense.
If you are doing lots of miles, then it'll wear the seats quicker. But a replacement head is the proper answer (or just get a cheap used stock head and start over). But I'd still not bother, run it until it becomes an issue and solve it at that point. Will still likely be the cheaper way of doing it and a lot less hassle.

If the additive was not used and it should have been would there be a noticeable difference in the running?

Hi John S, don't know the history, looks like it was parked up from 2012 to 2015 when the person I bought if from acquired it. Performance seems OK to me, I will sit at 50 to 55 mph in overdrive. I doesn't start very well when hot and when I turn it off after a run the engine seems to kick over a couple of times after the key is off. Timing issue perhaps ?.
There are ongoing jobs to do but nothing drastic, good fun too my kids love it. When ever we go any where it's dad can we go in the land.
Thanks, Simon.

There was a big discussion on the series 2 club about this and the general consensus was the wear was minimal unless as said above you do a lot of miles at high speed. Just save up and buy an unleaded head if you'd feel safer doing so but you won't have any issues for a fair few years.

sounds like you have a little carbon build up on the head and piston crowns which is very common in a old rover. if you really want to you can get a upper cylinder lubricant and have a look on the label it should have written use in cars as a lead substitute.
i agree

Carbon build up is a possibility Kommer....but I have occasional over run on my nicely rebuilt Engine thats set up correctly.....I cure this by letting her idle for a couple of minutes after a long journey.....Alternatively you can buy and fit a fuel cutoff solenoid.......Chris
