off roading a RRC with LPG fitted

Hi all i have a 3.9 V8 auto RRC with Lpg conversion, it has twin under sill tanks, what sort of off roading can be done with this set up? also what would need to be fitted to be able to wade through fords and the "lakes" we get on our country roads round here?

Cheers
Shaun

Hi I have off roaded a RRC for the last 3 years with under belly tanks I do mostly anything i just keep an eye out for any where i might bottom out like going over the top on steep hills ...I have landed on the tanks it just pushed the floor up a bit
I have now fitted a 2in spring lift to give me a bit more room
as far as wading.. it goes as deep as a petrol one ie untill the dizzy or carpet gets wet. remember your ecu is on the floor under the drivers seat. and if the dizzy gets wet its harder to get going again on gas Before you start just have a look under and make sure no gas lines or fittings are exposed for damage they shouldnt be
My theory is the tanks are stronger than anything land rover ever made and if you do get a leak the gas evaporates immediatley
I hope this helps

Ok, cheers for the info Ken, do you have to waterproof the electrics on the LPG system too?
Thanks
Shaun

Hi every lpg conversion is different but on mine I have just smeared waterproof grease onthe solenoid terminals which on my car are underneath near the tanks
most have a plastic cover [which is a begger to get at] on one of the tanks over the guage although this is supposed to be watertight it is worth a look to make sure the covers on ok
the electronics if you have a change over switch should be inside the car
the rest is under the bonnet and if you get water up to the top of the engine the gas bits are the least of your worries

extenended axle breathers and a wading plug for the gear box are a good idea if your playing in water.

cool thanks for the replies fella's

keep reading this but landrover say no... I have a v8 auto..

Hmm...interesting as all i've heard on here and LR4x4 is that if going near water use axel breathers and box plug

just had another look at the owners manual and the auto doesn't need a plug but the manual does... no mention of breathers... are they easy to get hold of and fit?

Breathers for gearbox and transfer box will come up and be clipped to the bulkhead just behind the plenum, the front axle breather should come up and be clipped just below the left hand (near side) suspension turret. The rear axle breather should be tucked up under the body at the rear right hand side (off side).

Extending the breathers is no big deal, I used the "B&Q" kit (garden watering kit!), connectors were a bit tight to get in but a lot cheaper than buying a breather kit and it is totally a DIY job.

If you're planning on wading a V8 you might want to think about a snorkel. If you are going to try and run the thing underwater, remove each plug lead and fill the end caps with grease, seal dizzy cap with a bit of sealant. Again, remove leads from plugs and fill ends with grease. Swap your viscous fan for electric and make sure you can switch it off. Grease up the connections to your coil and/or place it in a protective plastic case (small ice cream tub).

You might want to move your ECU while you're at it.

Oh and get a long tow rope!!

That should keep you running in most stuff.

So have I, but ive done the axle breathers and got a wading plug.
Ive also had contaminated ep90 in both diffs because i didnt have extended breathers. I would suggest you get them (seeing as its so cheap and easy) but up to you...

the breathers looks like they are worth it but not sure on the plug... where would you put it if LR say it doesn't need one...

not sure if I am planning on wading... just big puddles I think

I need to sort tyres out first cos I am running n nearly not legal road tyres right now so will change them over the next few weeks for something a bit more brutal.. then off to some lanes first I think... shouldn't need to go deeper than a big puddle there I guess... if I enjoy myself then I'll come back to all this then... I'm just getting ahead of myself really...

I would say plug before the breathers my self. the plug just hand screws into the drain hole on the gear box housing, you dont need to lift the car or any tools. this has probbaly taken longer to read than to do! If you go through a puddle with more than about 3 inches of water slightly quick you could contaminate your transmision oil. Just put the plug in and at as you need it. the axle breathers is slightly more involed, and exteneding them is actually replcing the existing breathers which vent quite high up on the car already(hence the LR specified wading depth.)If you do searches on here you will find instructions and sources for these mods that will take less than a morning (even for a novice) and cost at most about £30 quid, which woll save you reapairs and replacements which will take a lot of time and money. I peronally bought a kit off ebay, but most people on here do it them selves and have posted how to guides on here.

thing is if LR say the auto doesn't need a plug presumably LR don't do a plug for the auto... so do you have to fabricate summat or can you buy one from somewhere... or is it the same as the manual...

and I am a little confused why LR say you don't need one if there's a big hole in the gearbox that one fits in..

Not quite sure of the size of the wading plug,do a search on here.If you pay more than about £1.50 you've got a dear one!
