Hi I have the same problem I have a 1988 Isuzu 2 tonne truck with a 3.6l turbo diesel. I have dyno'd it twice and picked up 1.5 hp from 80hp to 81.6hp so I have actually noticed the increase in power but no noticeable increase in the fuel economy. What I am wondering is whether the cell I am using is the problem as I have tried from 5 amps through 25 amps in 2.5 amp increments and start to lose economy over 15 amps. I have just fitted a cell to my 2012 toyota corolla 1.8l petrol and filled the tank then drove 120 km and the fuel gauge is still reading above full, so it seems to be working but I will know more when the tank is empty. So I don't know why the diesel ins't working but they do sat 10 to 15% is what you get in gains. So keep trying.

Hi, try to hook up the hho gas hose into a vacuum line of the crank case (with t-connector) NOT directly b4 the turbo. That might help. Its not getting enough vacuum to "pull" the gas from the cell. How much hho production do you get right now? Greetings, ****

I have a 2005 Kia Sorento under excelliration it blow a lot of black smoke could it be the intercooler leaking as i check the oil regularly and it never uses any,


black smoke is over fuel and in a diesel with a turbo that indicates that
1 the turbo variable vanes are not adjusting to low rpm
2- the turbo turbine wheel is not spinning up
3-the intercooler or hoses are leaking boost air
4-- bad injectors -- squirting and not atomizing

Fixya. I have no idea how my question has related to a 2002 Montero. The car in question is a 2005 Pajero 3.2 turbo diesel. Same questions still apply.


You need to have the brakes bled. What happens is you pump up brakes and hold while another person unlooses brake line to lest out air in the brake fluid. Its down for all 4 brakes and then you will have a good brake pedal.

A 2004 E350 turbo diesel van 6.0 liter keeps getting airbound and shuts of


check for loose hose fittings -cracked fuel lines --leaks at the fuel filter gasket--leaks at the pump shafts . I would be looking at the filter gasket as it may be not be sealing properly. Check that the air equaliser valve at the top of the tank is not blocked and creating a vacuum in the tank

My 2006 Sprinter has over 30,000 miles and when going up long, steep slopes it slows down, but keeps running smooth. I did change the fuel filter recently and that did help but did not solve the problem. ...


YOU HAVE A AIR LEAK IN THE TURBO SYSTEM CK HOSE'S MY 2006 3500 SPLIT THE HOSE HIGH WHISTLING SOUND. LOW POWER / AND LIMP MODES TOO. ORDER THIS AND BINGO IF FIX IT . YES THE OLD TURBO RESONATOR HAD SPLIT TOO. I did not use the o-ring from the old part I found one 1 side down that fit tight around the new part. A loose o-ring is going to weak air too. Got mine on ebay.

My car wont start, 1997 vauxhall astra 1.7 turbo diesel


This sounds like a problem in the fuel shut off circuit. When you turn the key on, it energizes the fuel shut off solenoid on the injection pump. When you turn off the key, power is removed and the pump is moved by spring to the fuel off position. Check for power at this terminal when you are having a problem, ( with the key on) If no power then I would check the wiring and connectors from this connection to the Ignition key. I believe it is wired direct. That can be checked at http://www.alldata.com/products/index.jsp

subscribe3 and get a wiring schematic for the car and see if it is wired direct to the ign switch of from a relay, I am sure it is a connection problem if you have no power.

A 1.7 diesel even if turboed, is dead slow in any vehicle let alone a van. Enjoy the fuel economy

good luck

1985 B reg T3 Transporter 1.6 Diesel LHD


Does anyone know if it is possible to put a bigger engine in the T3 as at the moment we have a 1.6 not turbo diesel and we can only do 90 kmh . we thought that maybe another engine and a five speed gearbox but which one will go straight in and if we have to adjust anything what would we have to change to get a bigger engine in. I don't suppose there is any chance of putting a turbo diesel engine straight in? Also why do you not have T3 1985 listed > I had to put this under 1986,

Anyway we managed to tow the T3 1985 camper to a garage and the problem isn't that bad .
Because the belt was slipping it wasn't turning the pully fast enough to cool the engine which is also why the rev counter was eratic apparently.
We had a small hole in the top of the expansion tank which is where the water came from (which will be replaced) and apparently the bit of oil had come from what looked like the flywheel casing anyway the mechanic got some long nosed pliers and pulled out a plastic tube from it (behind the line of injectors ) he seems to think that somthing is missing that conects to it - what ? i'm not sure, as my French isn't that good.
