hi urm ive been in and out off this formum for a while and can i say its bloody usefull!
i have recently had alot of problems with my rocky, total loss of power poor starting and lots of whire smoke, upon talking to a friend on new years we managed to concluded that there was water in the system!
so i thoought nothing off it and off i went offroading as usual, coming down a steep hill to the bottom and through some rivvers and deep water, when i was going back up the hill, half way up my foot to the floor in low box (it was very steep) total loss of power! and the engine was below idel speed eben though my foot was to the floor. COCK!!!
i rolled bacvk down and eventaly got up with help of piss taking from friends any way back on the trailer and home, i took fuel tank of and completly shot, so new tank going and and hopefull it should start, run and frive one hell of alot better!
just thought u should know if any 1 has the same plroblem!
cheers henry
Blown it !
Its not water in the tank. You have blown a hole or cracked the cylinder head. At least expense it could be only a blown head gasket. Loss of power is due to no compression in the cylinders and not inclusion of water in the fuel. Water in fuel causes missfire.
Since you continued driving knowing the car was 'burning water', I suspect a hole has probably been blown through the cylinder head due to a hot spot ..... uncooled area. White smoke is a sign of water being drawn into the cylinders and burned with the fuel. The white exhaust is the steam. Water gets into the cylinders when the head gasket has blown a hole from a waterway into the clinder. Standing over night water/coolant drains into the cylinders and produces masses of 'white exhaust' on starting. When running the coolant continues to get sucked into the cylinders and 'burns' with the fuel producing 'white smoke'. Eventually a hot spot is created on the cylinder head and a hole gets blown through the cylinder head.
You say it has total loss of power. I suspect the cylinder head has cracked and loosing all compression.
PS .. have you checked the radiator coolant level and coolant bottle? I bet its empty of coolant.
thanks
upon checkin the cylinderhead it is totaly sound and the rad has not go down since i dropped the water out and anti freezed it.
so i still think its the fuel tank.
you say that there must be water in the fuel coming through the coolant, but surly if water is mixing with the diesel in the tank and it is bieng pumped into the injectors then this must be the same as having cooland in the injectors, the reason i came to the conclusion of it bieng the tank was in summer it is ok, as no water on longs grass or puddels ect, and when i was driving through the water coming back up the hill it would just die, but then find power, most probaly getting a bit of diesel to fire on and off it went until it did it again and so on!
i will put the new tank on after my exams and have see what difference it makes as the tank was totaly shot any way.
many thanks herny
Dilute Diesel
Common problem, water in the diesel tank, two main causes:
1/ water ingress from heavy wading when off roading, a warm tank will suddenly contract, if the tank is immersed in cold water, and the tank breather is submerged, this sucks in small quantities of water.
2/ The most common cause is condensation, this forms when the air in the tank cools and condensation builds up inside the tank, this forms into small droplets and runs down the inside of the tank and into the fuel. Fuel floats on the water, when climbing steep hills, water accumulating in the tank is sucked into the fuel line, this causes a loss of power when the water trap on the fuel filter is not emptied on a regular basis, or if a significant amount of water is sucked up.
SOLUTION - keep the tank as full as possible, this minimises the amount of air space in the tank, thus the amount of damp air which is in the tank. Drain the water trap on the fuel filter on a regular basis, this ensures you have maximum capacity in the filter for the water seperated from the diesel during filtration.
Water in Cylinders
All the info. provided by other members is good and could be the problem howebver if the water was very deep and you wernt using a snorkel or you allowed the exhaust to suck water in buy taking your foot off the power with the pipe beneath the water then the symptoms you decribe could be caused by a flooded engine although I would have expected it to cut out completely.
