What was the engine like when it was last running ? I just put a squirt of additive in now and again only for piece of mind really and never had any issues, saying that it will probably pop when I take it out next lol
Evening Chaps. Before I go to mad on my 850 motor, I would like some feedback on valve seat issues. Is it common practice to renew the valve seats and valves to suit modern fuels?
In the good old days (about 5 years ago) it would have been thought fairly important to have new valve seat inserts, but a lot of experience since then shows that the economics of this are at best highly questionable.
Of course, if you are a total purist, then go ahead with new seats.... BUT... this is a very expensive and disruptive option even if you have the engine out, never mind if you don't, considering that you have the very practical alternative of just dosing from time to time with an additive.
Add to this the time factor - whereas running your daily driver for 20,000 miles a year on the 'wrong' fuel would certainly destroy your engine, running the Reliant engine (which is one of the most robust and abuse-tolerant little power units ever made) for just a couple of thousand miles a year, under most likely very gentle conditions (unless you are also fitting a turbo and running nitro... you're not? Thank goodness for that!) - and it will probably not be in your lifetime before you can detect any noticeable difference in operation of the engine.
Previously I would have left it at that - don't bother unless you have just won the lottery, just use an additive.
However, changing the valve seats "to use unleaded fuel" does rather assume that "unleaded fuel" today is the same as it will be next year and the year after. Of course, with first E5 and now E10 we know this isn't the case. And there's talk of even higher E numbers to come. And all of this could change what is the best valve seat to have.
There's little point in going to all the effort and cost of changing the seats only to find that later you have to do it all again!
Added to that, with the impending move to electric vehicles, it seems the availablility of *any* type of unleaded fuel is now being called into question.
You might find it worth watching this video from Harry's Garage - in which he talks about the likelihood of unleaded fuels being replaced by "synthetic, carbon-neutral" fuels - so again, what will be the right valve seats for *that* ?
So today my advice would be, just live with what you've got, and make the best of it with an affordable additive, because who knows what fuel changes are coming in the next ten years or so? And the law of sod says, if you spend a chunk of money on your engine, whichever route you choose will be the wrong one!
If you have a question your better of starting a topic in the main forum.

mybug: Anyone know the whereabouts of PTO 365M? It was mine back in the early 80s and some pix have surfaced here (apparently from ebay around 5 years ago) so is it still around?

karl: Andrea, just seen your post. if you're still looking try putting it in the for sale wants thread.

mybug: Searched and spooled through every image/video/old ad I can find on the internet, I'm thinking that PTO 365M is not around any more. May be resting in a shed, but given the small and tight-knit Bug community, I'd have thought that someone would know it.

heartnut: Quick question: If I fit a Lucas 15/16/18 alternator, is it true that it will heed fibreglass work to fit it as the body is bigger than the original generator?
