Im wanting to convert my 2002 V6 2.0 X type to lpg,but have been given lots of different stories regarding Valve seat recession.Anybody help?

If your 1997 Mitsubishi Starwagon has been converted to run on LPG (liquid petroleum gas) and is having trouble switching back to petrol, there could be a few different issues at play. Here are a few things you could try:

1. Check the LPG/petrol switch: Make sure that the switch is in the correct position for the fuel you want to use.
2. Check the fuel lines: Make sure that the fuel lines for the petrol and LPG systems are not blocked or damaged.
3. Check the fuel pump: The fuel pump may not be working properly, preventing the vehicle from switching to petrol.
4. Check the fuel tank: Make sure that the petrol tank is not empty and that there are no blockages in the fuel lines leading to the engine.

If none of these solutions resolve the issue, it may be necessary to have the vehicle diagnosed by a mechanic. They will be able to identify the cause of the problem and recommend the necessary repairs.

as lpg expands to around 200 times the liquid state it will be difficult to calculate as how you want it
the car has a liquid tank but the liquid is converted to gas in a converter on the manifold.
basically from experience an engine on lpg gets about 75% of the mileage as if it was on petrol for the same amount of lpg in litres
talk wit an accredited specialist automotive gas fitting shop and they may be able to give you a better idea
you can work it out by filling the lpg tank to shut off and setting the trip meter to zero and then when you have done say 100 klms refill the lpg tank to shut off and that will indicate how many litres were used in that 100 kilometers

the fact that it runs on fuel means that the electronics of the vehicle are all operational. The problem is the fuel selection process for he LPG. The converter for the lpg is prone to corrosion and failures internally so I would suggest that you have an accredited Auito gas specialist look at the gas system

It is normal. All LPG converted engines start with gasoline. Then when they reach 2000 rpm move on LPG system.
If you want to start directly with LPG must call a professional to modify your installation.

hi your issue is that your car which starts with petrol then switchies over to lpg for which youll already know ,but the problem lies within the cylindar heads as it can only be 1 of 3 things =1, your valve seals are worn excessively due to the lpg as that runs at a higher heat density which stretches the valves which in turn causes then to wear and that reduces the power ie lack off,as it puts the ecu into limp mode (safe to protect your engine) as its a common fault on ALL lpg conversions.as that is also the knock on effect with your master servo (brakes).as i fix approx 3/4 a month.
hope this help's to clarify what is wrong ok

YES, I have my 5.2L V8 GC with LPG just will need some few modifications in the air intake system.

AFTER...



and keep in mind that LPG tank location...




Good luck.

All LPG kits are custom to vehicles they are being installed on. The possible problems are the same with all models. They include Leaks, lose of Mileage and the obvious dangers of filling the tanks when needed. I will tell you this much, it is unlikely you will save any money converting to LPG as most conversions get far less mileage than they do on regular fuel. Also, a Conversion kit is a full conversion. Once installed you are not going to have the option of switching between the two when the LPG system fails. You would think with the faster burn rate you would have better acceleration in LPG vehicle and better Mileage since the Typical LPG fuel is a higher burning and cleaner burning fuel but in reality it it usually just the opposite in conversions and they have a tendency to vapor lock more often.

FILL IT UP FIRST ...DONT TRUST THE LIGHTS MAY BE A SELONOID GONE AND NOT LETTING THE LPG THROUGH

areas to check are the fuel pressures, fuel hoses, fuel crossover solenoid
It indicates that the ECM is receiving the correct information from the sensors to adjust for LPG but when crossed over to petrol signals from sensors are not as clear as they should be
This can be from a power drain to components caused by a faulty solenoid or relay that is reducing the voltage available to the sensors ( normally in the air intake system or the heated oxygen sensor in the exhaust manifold )
check all harness connections and wiring
if you are checking it all your self then a workshop manual that has all of the voltages for each sensor would provide help

we have solved this problem.
