My gttdi 150 diesel golf is exhausting through the inlet
My deisel golf is exhausting through the inlet, it is making a popping noise and is running flat, sounds like a big end bearing noise but its not, when you take anything off at the inlet side it sounds like a very deep pop,pop,pop.
egr has been checked,turbo is only 1 year old and original,
the garage seems to suspects something amiss with the valves,but i am not convinced,
it happend about 3 months ago for about 15 seconds then went off, the car goes like stink(very fit), but then my other half went on a journey and it came back on for quite a while in a very flat mode the put itself right, then the following day i then dropped her off, but had to pick her mother up, but when i pulled over it happened again and has not recovered,and is now in my friends service centre, could this be the syptoms of a sticky valve?

That depends on the amount added and the engine, yours would be 7 parts diesel to 1 part gas. I do not have the different effects on engines using different ratios of deisel to gas, I suspect the richer the mix ratio of gas to deisel, the more noticable the reactions will be. First off there are two immediate impacts of diesel fuel mixed with gasoline: the octane is lowered and the fuel vaporization is reduced. The lowered octane may cause the engine to knock. Some engines have knock sensors and the electronic controls that will adjust the timing and other engine conditions to try to control the knock. If the knock remains significant it can damage the engine by causing metal fatigue eventually leading to failure of critical parts like pistons, connecting rods, heads. Some very old engines (e.g. 1950's tractors) can accomodate lower octane, but the ones found in recent autos are normally running close to the knock threashold. The reduced volotitility caused by the added diesel will cause hard starting and will probably result in some unburnt hydrocarbons remaining in the exhaust gas from the engine; these may be reacted in the catalytic convertor causing it to overheat. A modern electronic controlled emission system controls the oxygen level in the exhaust gas going to the convertor so the significant increase in hydrocarbons with controlled oxygen may save the convertor, but will likely result in unburnt hydrocarbons exiting the exhaust. This will result in a smell and air pollution. Gas will also damage deisel fuel pumps as well.
My Golf GTTDI had the exact symptoms your describing a week ago. knocking/shaking, lots of smoke, lack of power. the Hydraulic lifters had stopped working and the camshaft/followers had become mis-shapen. Had the lifters&cam replaced and runs like a dream now....
they will go soft a bit when engine runs as the servo is applying a lot more pressure its normal ,make sure you have removed the rear brake drums and adjusted the back brakes up manually and the pedal will go hard and the handbrake will tighten up as well
Hi,if you want to make sure its your airflow meter,get a buddy with the same car and just test his in your car..(A.F.M is situated on the left,behind your battery is the filter box,the pipe connecting to the box is where it sits)
one thing more,i want to know the specified..intake and exhaust clearance of,honda v tech engine.model 2000. Honda city type Z edtion..thanks a lot.more power...
jack up the car and look at the exhaust system..If you cant see or feel any holes or leaks then it could be up on the exhaust manifold..a peugot should not sound like a V8 diesel. you really shouldnt be able to tell its diesel until you floor it
Sounds like the pipe/connection from the exhaust manifold to the EGR valve that is located at or near the throttle body has a leak. That would make a loud popping noise.
