A friends P38 4.0 with LPG overheating......header tank empty......leaks apparent around the LPG mixer gubbins and a larger leak at (or close to) the bottom of air filter to inlet manifold connection gubbins (sorry about the description, but Im no expert...) Refilled the coolant (+/- 5 litres!!) and run engine on idle. some occasional bubbles apparent, but not continuous. Oil is clean in rocker cover. Engine came up to working temp and stayed there.??? Not driven it anywhere yet or called anyone out to it. Dont think its a head gasket problem as I know the LPG system uses the Hot coolant to vaporise the gas.....any suggestions? (apart from the obvious....) When engine was stopped, coolant "flowed" onto rocker cover and exhaust heat sheild producing clouds of steam.......cant see exactly where its coming from. Can any one point me towards a garage with P38 knowledge in Frodsham/cheshire area...?

I just took my hubs and everything off to replace the swivels on my '03 Td5 Defender......my hub nuts wernt that tight.....slackened off easily with a big box spanner and a bit of foul language....hope ive put them back on tight enough!!!!

Thanks for the input guys, unplugging the remote aerial and parking in a different spot (3m further away from the house)seems to have done the trick !! No sign of it waking up, no spurious alarms, and it was left for three days without draining. I'm happier with it now!!

Thanks for info, I've read various forums and websites on this subject, seems like the only sure fix is to buy the new reciever.........

Ive had spurious alarms and occasional flat batteries for a while now. And also heard various beeps and buzzes when working near the car (message:interior light on / off) Recently noted the faint glow of the P light on the gear shift is on most of the time. Read all about the radio interference keeping the car awake, or waking it up repeatedly. It all seems to be getting worse recently, flat battery replaced with a charged one this morning, bugger of a job getting alarm and immobiliser working with the emergency key code,disconnected the remote antenna on the back, finally got it going and went for a short run in it. All OK. Came to use it this evening......battery flat .......put recharged original battery back in, went for a longer run and have parked in a different position on the driveway, locked it on the key. Just checked and it seems to be asleep now (no red glow on the P), We'll see what happens in the morning. Anybody got any suggestions / advice (apart from selling the thing...)

There is if its chipped..............

My 4.0 V8 P38 averages 16mpg on gas but goes a bit further on petrol.....18mpg. I believe it goes down to single figures when towing a caravan, so I,ll keep using the 110 for that!!

I know on tdi's I've had the turbo inlet from intercooler was oily, I think its condensed vapors. I guess Td5's may be the same.....

Thanks Filip, mines an 01 model (02 registered) so its bosch, I set the gaps to 0.7mm. As I said it runs fine on LPG, I rarely use petrol now. (only a couple of mins for startup). The rough running at 30-40mph in top has gone now too. Thanks for info Mark

Just fitted NGK R BPR6ES standard plugs as recommended on another forum (cant remember which one now, but poster was happy with them in his 4.0 V8....). Gap is .75mm. Juddering between 30-40mph in top gear now gone!! The plugs I removed were NGK R PFR6N platinum, electrode very small and pointed. Changed the oil too, so now it roars like a tiger and runs smooth as a smooth thing....or maybe its psychological. Now all I have to do is remove the aerial for the remote, so the ECM doesnt stay awake all night and flatten the battery. Youve got to be mad to own any kind of landy. Cheers

Yummy, havent seen many large LR kits before....

Dont think it judders on petrol, Its a while since I ran on petrol!!!! Thanks for the info though, I'll see what plugs/gaps are currently fitted and fit the same again. (when the Mrs gets back from work in it!!) Thanks again

Thanks guys, I've had the car almost a year now, the leads look good (recent), Dont see a distributor-the leads disappear down the back of the engine. Really must read up on the engine and type of ignition system though!!! The LPG system is sitting on top of the engine so dont want to disturb that at the moment. I did have it serviced by a recognised agent a few months ago- he said fit good quality plugs and reduce the gap to 0.7mm !? Reading an on-line LR manual stated fit Champion RC11PYB4 plugs with 1.0mm gap, also not to adjust gap. I'm just going to change the oil/filter and check what the existing plugs are and what their gaps are at this time (unless I find any problems). One thing I have noticed is a misfire/juddering between 30-40mph when trying to accelerate (without kicking down)? Any thoughts on that? Once again, many thanks I'll let you know how I get on.

Hi, I have a 2001 4.0 V8 with a Tartarini LPG system and understand that the sparkplugs need regular checking/changing and they have a smaller gap than those running on petrol.(for a stronger spark?) What quality plugs should I use and what is the recommended gap.(I have heared about 0.7mm )? And should I be changing the leads at the same time? I'm new to the P38, V8's, and to the forum, and would like a little reassurance before I start fiddling with it!! Petrol engines always seem far more delicate than a diesel to me!!!! My other car is a Td5 110 G4 LE. Hope to hear from you experts soon Many thanks Mollydog
