While at for 9 hours I get two breaks I start it on each of these to see if itd help but it starts fine but then itll smoke when I get in it in the morning I dont really understand it. Also some times when I put my foot down hard it leaves a substantial amount of grey smoke behind I know diesels smoke in general :.
Ive checked for fault codes using forscan recommend by a helpfull member on here as was hoping it would of picked the miss up but nothing. I thought the injectors were leaking into the cylinders but surely it would act up all of the time ive also been thicking valve stem oil seals? Really dont know what else to do with it on an extremely tight budget so cant affird to take it into a garage so any help or advice would be greatly appreciated.
The car has a diesel chip on the injector rail I took it off but was still the same also has a pipercross air filter I didnt put these on it. Yeah it is also worse in damp conditions substantialy worse which is why I thought maybe glow plugs, its that much I cant see behind me when its started. Any idea on what I can do to test anything at home? What I was planning on was leave it over night and take the injectors out to see if I can see any fuel in the chambers but dont know if id be able to anyway willing to try anything right now to save the embarrassment nice looking car till its started I was also looking at terra clean but was advised if it is injectors it could make it worse.
I had this on my Corsa. Morning starts were very clean. But if left for a few hours, it'd chuck out loads of crap and judder, especially with a little increase in revs. The cause was 2-fold - the ECU needed updating to hold the glow plugs on longer, especially after standing between 1 and 10 hours. And the valve stem seals were needing investigation.
Valve stem seals expand when an engine is warm but if they're worn, they'll let a small amount of oil past and into the cylinder when they cool. Where the glow plugs weren't switching on because the car was used a few hours ago, it'd belch out a plume of bluish smoke and vibrate with a few revs. The blue plumes tended to be worse in the summer.
I would not advise doing anything to disturb the high pressure pipework unless there is a clear need. It is normally intended for one time use, due to the high integrity metal to metal seals.
And there is a risk of getting dirt or swarf into the injectors. Very small particles can damage seats and block internal orifices. If it was stem seals, you would notice the oil level dropping. And burnt oil smells bad, different to burnt or unburnt diesel. If you suspect the injectors, you could do a leak back test. Valve seals are utilized to keep the oil from riding down the valve stem and into the combustion chamber while the valves are letting air and fuel into the cylinder.
On top of this, piston rings are wrapped around the piston for an even tighter fit. This is most common in high mileage engines and is a sign that the bottom end has worn out.
It opens and closes, which keeps the intake free of oil. As auto manufacturers constantly push for better fuel economy, turbochargers have been finding their way into regular, everyday vehicles.
When a turbocharger goes bad, it will allow oil to get sucked into the combustion chamber. Glow plugs warm up the engine enough for the combustion of diesel fuel when a diesel engine is cold. Still pulls very strongly which I assume is a good sign Took it to my local garage who said it's fine and they can find no fault with it - I suspect they merely plugged in the computer and read the fault codes which were empty.
Some googling suggested either a blocked EGR valve or a split turbo hose but short of dismantling the engine I can't seem to work out a solid way to work out which it is. Any pointers? Is it using any oil? Well, the EGR valve is on the front left of the engine, and requires a couple of sockets and a screwdriver to undo the jubilee clip.
I cleaned mine out last week and it took about half an hour in total. Really easy to do. Jaskaran Gangster Joined: 19 Jan Posts: Had this problem on my brother's Corsa 1. So just got it replaced and it runs fine now. Sounds like an air intake issue to me. Whip the EGR valve off and give it a good clean. As said above, front left of the engine, remove the jubilee clip for the intake pipe, 2 nuts for the exhaust pipe to remove on the right, and a couple of nuts holding the valve to the engine.
Wear gloves and get some decent solvent to clean it. Consider fitting a blanking plate from a well known auction site - it won't cause any problems on a car. It could be a split intake hose - usually the one disconnected above. Get someone to rev the engine to about RPM and put your hand around the hose and you'll feel any leaks. The other place they can go is the pipe on the other side of the intercooler which is bound with wire.
Again, revving it should see help you find any problems.
