P38A Is it time to jump to LPG ? (4.6l Gems)

So long as you're not letting the fuel sit for weeks in the system you'll see no problem at all in any vehicle

That does it for me then, being a second car the old girl (with it's original steel tank) often sits for up to 4 weeks at a time.
Thanks for your input on the subject.
 
the lpg system on my 4.2 V8 supercharger I don't see a flash lube bottle anywhere in the engine bay on mine so going to presume it was never fitted

No issues with LPG in my 3.5EFi.
Never used flashlube.
Do run on petrol so it never sits in the tank for long & always on supermarket unleaded, rarely put more than £20 in at a time unless I'm doing long distance & LPG might be hard to find & I fill up with LPG & run on that until I have to switch to petrol.
Did a top end refurb a couple of years ago.
Bores fine.

A quick hand operated tool with fine paste very quickly showed the seats & valves were in good order.
TBH that was the one thing I was curious about but having run old engines on unleaded that were originally run on leaded & heard all the horror stories about rapid valve recession I do sometimes wonder if a lot of people just jump on the bandwagon with no experience of their own. My 1950 BSA 650 - cast iron head - did 30k miles after a full rebuild & when I had a look there was no wear to the valves & seats.

Thanks for that unleaded info, eases my worries about the valves on my old Toyota.:)
 
I used to run a D1 and a classic on lpg, Waste of time.
Constantly looking for where to fill up and always worried that I would run out when out in the sticks somewhere. Even though I had a full tank of petrol.
Very few garages have it now.
Costs the boot space that is very handy when needed.

Sounds a bit like running an electric car but without petrol as back up:eek:

1) Mine is a 3.5 EFI, but after my experience with LPG I'd never entertain a conversion again.
2) Not surprised, I used to run my WW2 Dodges & a Chev. truck on unleaded without problems, though like your Beezer they never needed high revs.

That's the main issue.
My range is around 180 miles.
Tanks under the sills so no boot issue.
No issues with them there as I don't extreme off road & for what I do - fishing & shooting - the diffs are at greater risk.
I think there may be an issue with air suspension & ground clearance but mine's too old for those.
A big tank across the boot would defeat the object for me as I make full use of the boot space & I'd not have converted in the first place.
Runs on petrol & apart from the cost I've never been bothered about lack of availability of gas.

Just had a quick look at one of the lpg apps (& rung a couple to check they've still got it) for the Cornwall run next month & still OK with the numbers which means I should be on gas there & back plus the running around.
Just as well, as the boat outboard's a 2 litre 2 stroke V6!
 
No,small hole drilled in the inlet manifold to take hose fitting, push on the hose mount the oil reservoir and top up with the lubricant,start engine and adjust the amount of oil being fed to the inlet manifold.
ah that's OK then thought might be a big job cause the SC on the top of the engine
 
Is that the "Sloper"? 750 single from memory.

Sloper 500 & 600.
Popular as sidecar outfits - albeit one of my friends had a wooden television box (minus tv!) bolted to the chassis of his 600.
TBF I had a chassis on my BSA with a tin bath bolted to it. In those days you could ride an outfit on L plates. :)
Didn't rebuild it as a solo until the late 80's having moved house a couple of times with it in bits & then used it as daily to & from work transport.
