you need some electraica switch cleaner.. and clean the end thats in the pipe between the air filter and the Turbo
as suggested before, clean air filter and passageways :thumb2
Then if as already mentioned its the cobwebs, try sticking in a jug of millers diesel power booster. As a cleaner that produces some excellent results.
One of our local taxi firms if a car fails or looks like its going to fail on emmisons stick some of that through on a mega dose. usually works. Shifts the crap :thumb2
Theres loads of support on various other diesel powered forum threads for this product but just to reintroduce an old discussion theres also support for chucking acetone in as a boost/cleaning agent :naughty
Black smoke is unburnt fuel, what also happens is because diesels run at a lower exhaust temperature especially round town, small amounts of unburnt fuel mix with the carbon on the inside of the exhaust, then when you give it some welly and the pipes get a rush of gas hotter than of late, this fuel is vaporised and comes out as black smoke, all normal unless the smoke continues, Rick
cheers daved i did just that and the smoke is no more.. at least it now seams theres noting wrong with my turbo:thumb2 and i never bought a maf:thumb2:thumb2
Refer to my earlier posts, injector cleaner does not work, full stop as you have now proven, the fact is nothing can dissolve carbon, and that is what most times is the cause of injector problems, others are dirt/water/overheating/deformation of injector elements, y
One thing thats just jogged the memeory cells mentioned to me this morning about this, does anyone remember the launch of Shell Power Plus in the 80's ??
That created quite a stir with its carbon and other cleaning properties :thumb2
It still is :dohIf it worked and was that good why is not still around. Rick
all i can say is ... i put injector cleaner in every 2 tank fulls ( red ex injector cleaner ) ..... after rick stripped the engine and i saw the amount of crap around the injector i ain't gonna be using it no more ..... but you pays your money and you makes your choice i s pose .
Fair point but seriously flawed as a decent evaluation how mucky were they before you put the stuff through ?
As a matter of fact I don't regard these products as a solution ie a liquid decoke. However they do seem to help. I'd be very interested in how solarman justifies his comments in the face of the alleged shell fiasco , the results of my experiment (which there was a lot more to) or the fact that retailers and manf are able to sell these things without comeback
:nenau
Due respect to Briggie, but he was looking at the general combustion area, and what all this is about is the injector internals, the most usual carbon problem with injectors is obstructed or partly obstructed nozzel holes which cause poor spray patterns and or carbon on the needle seat which cause poor atomization and dripping, there is no product that will cure these, the carbon in question is already subjected to to 2000 psi diesel fuel and I have had such injectors on the test bench subjected to much higher pressure with calibration fluid and never has it been possible to clear a blocked nozzel hole, mechanical methods are needed, I do not have a background in chemistry, but I have been dealing with all types of diesels for over 40 years, and my experience of most "mechanics in a tin" are completely negative, Rick
indeed daved , dont you just love how the group digresses threads :lol
