Anyone Got A Lpg Converted Ls For Sale (Or An Ls To Convert)

[Bluesman]

part of the research i did before purchasing was spending some time on here which helped me understand issues and importance of lpg cert and em light, but it wasnt on at purchase and lexus confirmed vehicle was fine when inspected. so i feel i did what i could. incidently after purchase i found the vehicles previous owner was a respected forum member here adding to the comfort factor.

additionally the cert suggested the lpg system had been fitted at 60k miles 40k before i bought it, so its done 110k on lpg can't have been that much wrong with it.

you can only do so much research. and profess gas cant be the only people in the country that fit lpg properly ? im in nottingham.

id still go for another lpg hence my posting, thanks for the pm messages guys i may be in touch

Regards

Profess have opened a branch in Chesterfield that might be better for you, if not I know a really good guy in Peterborough. Mike

em light wasnt on when purchased, someone had cleared the EM Code and it had an lpg cert, when it came back on i got the car serviced, light went out, got the car lpg serviced it came back on after 500 miles, took it back to different lpg service centre who confirmed brcs system was set up correctly for vehicle, Back to lexus dealer who said em diag suggested it was running a little lean but within tolerances for its age/mileage. did 50k with out issue now done a total of 140k which i agree is about 100k less than id expect from my other lexus 400's ive had over the years.

LESSON: is prob to have the plugs and em checked on regular basis if your running LPG, incidently it had a lexus service 2 months ago but i elected to just do a "b" service. if you put the lexus approved titanium plugs in at service interval i guess i wouldnt have had the issue.

disappointed but not devastated, it appears it may be corrected by re-threading or is this a bad idea

If its hellicoiled (re threaded) the new plug should be OK as long as no damage has been done to the valves or piston. & the cause of the overheating sorted.

Hi Colin

Running lean with the light on is not within accepted params in my humble opinion - I have done 206K+ in a 430 and have usually put the Lexus plugs in. I would expect if it is running lean it will run hot. The Lexus dealer in Coventry was always great even with the conversion - I usually use an indi now and occasionally go back to Lexus for a special treat.

If the Lexus dealer say they can fix it then take their advice and guarantee - and don't pay if they don't fix it.

Bren

bren, that seems a reasonable assumption in the circumstances my technical knowledge extends to opening the bonnet and filling the washer bottle thats why I buy lexus ...

You are spot on Colin - I'm an engineer so understand some of the stuff - one of the main reasons to go to Lexus is you should be able to trust them. If they inspected and serviced my car (LPG or not) said it was OK and then it blew up I would have somebodies man vegetables on a skewer or need a pretty god explanation.

Good luck with the fix mate. I see in later posts people say go to Profess - well they may be good but as somebody else pointed out they are not in every town in the Country and there are other really good people out there converting cars. I would always try and go with a recommendation for a supplier and make sure that they have successfully converted the your model in the past.

Anyway back on subject is the OP interested in any of my two LS's?

cheers im gonna stick with 430's as ive found if theres a prod i can get the existing lpg system moved over at a reasonable price

cause of the overheating sorted is a good point, do you agree that this could be the lean running, id certainly want to see the condition of the other plugs, its my regular lexus dealer and id accept a guarantee on the work.

One of my pals had a 430 go bang - it was exhaust valve seat recession. The car had done 72K ish on LPG - no lights - it just started running a little rough - a compression test revealed the bad news. £5K from Lexus dealer or £2.5K from Toyoda for the head rebuild - they also recommended Flash lube :) Colin you may want to get your valves checked out before they carry out the repair - I assume they have already suggested this but........

I am with you but the problem with the LPG trade much like many other trades that are riddled with cowboys, how do you know they aren't any good, in the normal way of things you don't really know until you've spent your money and the problems arise, so until someone else comes along and demonstrates their professionalism as Leon at Profess has done you need to be very wary of all the others.

I think the future should be better for the LPG trade and customers alike. Car manufactures are producing ever more complicated engines and electronics the cowboys will throw the towel in because they just don't have the knowledge and this will show instantly by cars not running at all without the specialised knowledge for which you need to study for, and that's something they haven't got the brain for.

Ive got a quote from lexes dealership for the suggested helicoil and fix a reasonable sounding £700 quid, Given the advice i recieved here I asked the following questions:

Where are the Bits that melted away, rolling about in the cylinder/Engine ?

Condition of other plugs ?

Results of a compression test ?

Fantastic Colin - you asked them all the correct questions and got no answers. They need to bore-scope (put a camera down) each cylinder and check the condition of the valves etc - or take the head off (big bucks). But they need to find out what went wrong and if there is any damage - the bits went somewhere - even if they were vaporised then they are now in the exhaust - get an emission test done as part of the fix so you know your cats are OK. They probably are because any metal vapour will have condensed in the top end of the exhaust.

Keep pushing (nicely) and asking until you get sensible answers - try the service manager and then the dealership principle - point out they checked the car out and said it was OK. Always be nice and shame them into giving you good service if you have to :)

Bren

[mikesands]

Colin,

have you seen my other post - my guy has discovered what's wrong with mine. Sounds like a simple fix but only a cheap one if he can find a second hand strut.

I mentioned to my guy about your spark plug problem and that you might be interested in him swapping my engine into your car (that was before we knew he could fix mine). His reaction was the same as Lexus - it's definitely fixable and he's fixed them himself - doubt he'd charge anywhere near £700.

Anyway if you want mine it will still be going cheap even when he gets it fixed as I have now moved on.

my usual service manager is off sick at the moment, the toyota guy is doing his best holding the fort, he has full access to my history over more than 10 years. im in no rush ill post a photo of the damage if i ever get one. apparently the helicoil guy is prepared to remove the head in that quote as access to the cylinder in question is hampered by the installation of the LPG Ecu. Ive spoken to leon at profess about swapping out my lpg they are not interested in doing it chesterfield at the moment, but he's been following the thread and suggested some of the questions above (due credit goes in that direction).

Good news on the strut but at the moment i seem to be on the repair it track for mine, you get attached to these beasts

[Profess LPG LTD]

Hello Colin.

I think i must have mislead you to think that we are not interested in your vehicle.

That is not the case, I simply do not want to you to have additional costs to what you already have to pay now.

It may be the case that there is no issue with your LPG system at all. In my opinion, you should get your engine examined thoroughly, that does not mean take the head off. Toyota/Lexus can use the the flexicam to look at your valves and pistons etc. They can also take your centre box and manifold off to examine your CAT. Try to limit their spending or you will be left with a heavy bill and a non running vehicle. If you are going to spend £1000 to examine your vehicle, you may as well get a new engine.

If you need to have your LPG replaced by ours, I am more than happy to oblige. Whether it will be in Chesterfield or South Wales.

I wish you the best of luck.

Kind regards

Leon

Profess LPG LTD

[colinrobinson]

Leon, exact opposite I was very pleased with your advice and dont want you to get the wrong idea.

it may not have come over well i was referring to moving my brcs system to a new vehicle in the chesterfield branch which you explained you were not yet set up for.

[Profess LPG LTD]

Hello Colin.

Yes you are correct.

At present we are unable to service or provide repairs on any system other than AC Stag at Chesterfield.

Our technicians are fully trained and authorised AC Stag installers. They have the expertise to look at other types of systems but we are reluctant in letting them do so,due to them not having the parts on the shelf etc.

Here in Wales we service all types of kits at any time.

I hope this helps and i wish you the best of luck with your diagnostics.

Kind regards

Leon

[colinrobinson]

The initial diagnosis from lexus dealer (4 days on) , non standard and possibly incorrectly fitted Spark Plugs unable to meet the requirements of the engine, the plug was NGK , lexus approve and would have fitted denso platinum plugs. he also suggested that lpg burns hotter than fuel possibly contributing to the failure.

no visible deposits in cylinder so recommendation is to continue with helicoil and compression tests on all cylinders before continuing with further repair and plug replacement. ive requested all the removed plugs be retained, so ishould be able to confirm to you guys what was fitted.

Regards

Colin

[Profess LPG LTD]

Hello Colin.

NGK are a good make of spark plug. I cannot say they are the best for your vehicle, but they should not fail as drastically as described. LPG should not burn hotter than petrol if correctly mapped. It has a higher calorific value and RON which makes it burn longer.... The temperatures that Petrol and LPG create whilst being burned within the cylinder head could not melt a spark plug. Something more drastic has happened in my opinion, such as the cylinder was running lean or rich for too long. There is also the possibility of the plug not being fitted properly in the first place. If the plug was able to draw in air, you will have a rich mixture burning at all times.

Once again, I wish you the best of luck.

Kind regards

Leon

Heres the Update,

Thanks for the images my plug is in a worse condition but otherwise similar to the pictures you posted ill try and insert the image at the end of this post.

Ive had the helicoil and compression tests done, dismayed at the compression test results in PSI they are as follows:

windscreen end

190 psi 180 psi

145 psi 180 psi

155 psi 180 psi

155 psi 200 psi

As you can see all the left Cylinders look to be poor, Lexus engineer states they are in spec However the spec shows the min expected pressure to be 143 psi, and its 145 in the affected cylinder ! The fitted plugs were NGK bkr6eix-lpg 4 of em look to be in similar decent condition but the others while in tact look different.

The repair with replacement plugs and a single replacement coil was £850

the diagnosis was incorrectly fitted out of spec plugs, but having driven the car back from the dealers as soon as it switched to lpg the engine management light came on which i wasnt expecting, its going back tomorrow to get the fault code read.

how do i post the image(s) ? (Pm me an email address and ill email them if interested.)

Leon, whats your opinion re the compression results ?

[Profess LPG LTD]

Hello Colin.

A drop in compression by 25% is not a matter to take lightly.

Although Lexus have stated that 143 is their guideline of disrepair, it may only take 1 turn over of the engine to place it within that criteria.

In my opinion I would hold off from any repairs if they cannot guarantee any amount of miles on the repair.

Sorry to be the person that brings you the bad news but i feel that you should be looking at an alternative engine or a new motor.

Best regards

Leon

Profess LPG LTD.

[colinrobinson]

Leon cheers, thats my thoughts appreciate the frank opinion. they wouldnt guarantee any mileage either. time to look for a new one don't think its worth swapping the engine.

maybe a trip to chesterfield soon then as im now sure this wasnt LPG Related, the other half of the engine seems fine and its done the same mileage ... I wont accept any nonsense about engine warning light and chalk it down to a learning experience.

Regards
