I've trawled the past threads for the last hour but can't find anything like my problem. On the way back from the National War Memorial Arboretum today my Td4 kept on losing power momentarily and blowing blue smoke. This happened every 100 yards or so, like I was touching the brakes, then blue smoke, then running fine.It wasn't too bad at first as I was doing around 60 so was more like a blip.But slowing down to 30mph for side roads this became more frequent. Couldn't make any speed and had to drop down the gears just to keep up momentum. Cars behind me backed off. Made it home and turned off the engine. Checked hoses-all slicone - and couldn't find any splits , cuts etc.Turned it over and it ran sweet . Revved it up and no smoke.But out on the road, same again, like I was applying the brakes every few yards,with big plume of blue smoke.
Turbo problem?

Fuel pressure I'm thinking? I had a similar thing happening with my Pajero which is totally different beast, but symptoms were the same. Anyway, it was a blocked fuel filter causing fuel starvation. This meant that as the pressure dropped, and car turned into a gert lumbering sasqwatch with asthma. Then if you stopped and just idled, enough fuel would get through and fill the filter and so you could drive off again until it ran out again. And so on...

Anyway, if the fuel pump was not delivering enough fuel, this could happen? Or intermittent fuel delivery from the pump?
 
Changed the filter - although old one seemed ok on removal, what I mean is that blowing through it the diesel came out in a good steady flow until it was empty. Seems to start ok now and drives nicer, so hopefully this has cured it. Thanks.
 
Cool, keep us updated if it works.

On my Paj, it went again and again, until I finally drained and cleaned out the tank and found an inline filter on the pickup that was clogged like a 90 year old's belly button. Cleaned the tank out and filter and all was good... It was due to accidently putting unfiltered waste veg oil in instead of clean stuff. Thankfully, shouldn't be a problem for you!

:eek:. Before it became stupidly expensive,I used to go to Asda and buy 30l of veg oil and fill my 110 on the car park. The look on people's faces was one of sheer horror and disbelief. I always topped the tank with diesel straight away, but eventually my high pressure fuel pump gave up the ghost. :D
 
Yeah, I used to do that, but the veg oil doesn't quite mix and you get some thicker oil at the bottom of the tank, which strains the pump, as you found. Best way was to mix in drums then leave a day or two then pump in. My method was to heat and stand to separate, then filter the used oil from my Chinese chippy mate's. Then put in a drum with petrol (5% IIRC) and some diesel in winter with cetane booster. Leave a couple of days with a shake every day. Then pump in. Did about 50k - 80k miles like that I'd imagine. I've still got about 19x 25L drums of unfiltered (but good) oil in the yard and my heating/ filtering big oil drum (which is also full of oil at the mo') complete with pump and filters in the shed, all of which will be on ebay soon. Might put an ad on here first...

If you're bored have a look here at my setup: The Mitsubishi Pajero Owners Club® :: View topic - My Waste Veg Oil filtration system

I also have a spare flat plate heater as in the last pics on page 3 for sale.

Rover Ron recommends changing them frequently, much more than Land Rover recommend.

Ah, that would explain why my Synergy 2 has now found a new lease of life aswell. Performance was down, but after changing the filter, it now drives great when it's switched on, setting 4.:D
