It's sad to read this, Jay. Hope you pull it all together and week work. Had similar problem 10 years ago with Chrysler intrepid with lpg. Since this I don't use gas even in the lighter.have my zippo hehe. I know lpg make driving cheaper (especially Jeep) but I know personally at last 7 people who had same fire problem with gassed car and nobody on petrol . Good luck.

Cheers Jarek,

Its a fine line between if I spend a grand and get it sorted can I get another 2yrs motoring out of it, fairly trouble free.

Or What is it worth mullered a grand, then if I put another grand to that there isnt much Jeep / vehicle I can get for 2k.

Sorry to hear you are having problems with it Jay.

I recall we chatted about LPG a while back.

At this point, I'd pull all the plugs and do a compression test, then, assuming those numbers are OK, try a new set of plugs in there. Bit of a long shot really, but a badly flooded plug will never work properly again so worth a try at least.

I read that the 4.7 is an engine that has to have valve lube on LPG - did your installer include that?

jay140285 · « **Reply #29 on:** October 22, 2012, 04:04:56 PM »

Chris,

Already done it.

All new plugs in the following day, still no better, coils all swapped round to check those, still no better,

Yes it has the flash lube fitted and checked on a regular basis.

Pressure test done and its pressurising within seconds.

Are the 1 2 3 compression numbers a good match for the others in the engine?

Does sound like you've covered all the basics so maybe time to dig a bit deeper. The way it came on does sound a bit odd, mind.

Perhaps blown HG was a good call.....

Welcome to my world Jay, look inside yourself..... are you ready for a 51 plate focus

....... no ? thought so. The money is a very temporary short lived pain once you've got the WJ up and running again, trust me.

When we have started to think about it, it has been smokey (white) especially on start up, MPG has recently dropped and I had a coolant leak which now I know was obviously due to the increased pressure build up.

Dutch - Errrr no. WJ will be on the mend very very soon. All been well booked in for this coming Monday.

Sorry to hear about your woes Jay. If you dont mind me asking whats the quote for the fix

jay140285 · « **Reply #34 on:** October 23, 2012, 08:39:15 PM »

Around £600 to £700 mate.

Bubba · « **Reply #35 on:** October 23, 2012, 10:21:15 PM »

i honestly think this needs to go back to the lpg installer

I cant believe that the Bishop was actually right all along with his sermon on LPG

Kev,

I know what your saying, but surely they will just come back with wear and tear etc etc.

Bubba · « **Reply #38 on:** October 25, 2012, 05:05:06 PM »

after just 8 months ? harsh fuckers if they dint come at least part way

jay140285 · « **Reply #39 on:** October 25, 2012, 10:52:31 PM »

I will give them a call, whats the best line to go down in my discussions?

Panic mechanic! · « **Reply #40 on:** October 26, 2012, 05:03:45 PM »

I gave you a perfectly good jeep with no problems, you fitted lpg kit, now engine has blown headgasket, sounds to me like you set the lpg up wrong and too lean and engine has now over heated. ( don't mention going to france in it), mutter about going to see trading standards and they said you should approach them first.

Bubba · « **Reply #41 on:** October 26, 2012, 08:09:42 PM »

also nagging in a dark corner of the back of my head is cylinders 1 2 3 are showing misfire so thats both banks of engine if gaskets are gone thats awful bad luck compression on cylinders tested would make me more happy

Lukemagnum · « **Reply #42 on:** October 27, 2012, 08:21:14 AM »

Hopefully put your mind at rest. I think you'll find 1,2 and 3 are on the same bank. It's cylinder number not firing order.

Bubba · « **Reply #43 on:** October 27, 2012, 10:12:10 AM »

i hope you are correct as that would help alay my thoughts i have always referred to cylinders by firing order and assumed that was the norm as it had been even at work

Jonny Jeep · « **Reply #44 on:** October 27, 2012, 10:52:42 AM »

Left bank is odd numbers, right bank is even. It's both heads unfortunately.

Lukemagnum · « **Reply #45 on:** October 27, 2012, 02:10:06 PM »

I stand corrected.
My BMW counts 1 to 4 left bank 5 to 8 right, Chrysler obviously like to do things differently, my Jeep is the girlie version with only 5 pots in it, so I've not needed that info.
Looks like its down to old fashion compression testing.
Having said that, considering it's going in for major surgery and the likely cause of it, if it was mine I think I'd consider having both sides done anyway.

Good luck.

Bubba · « **Reply #46 on:** October 27, 2012, 04:53:09 PM »

if confirmed both heads would be the natural cource

jay140285 · « **Reply #47 on:** October 28, 2012, 01:52:57 PM »

When ever your free Kev, its here for you to do compression test then we can tow it to yours.

Jay, wondered about that: thought you couldn't tow a WJ..... permanent 4wd and all that jazz
