SOURCE: whine coming from engine in 1st and 2nd gear up to 3000 revs

sounds like turbo unbalanced, check oil feed pipe for turbo could be blocked or restricted. turbo should be reconditioned or renewed.

SOURCE: intercooler leak

Hi if your boost gauge is still showing that there is boost pressure, but you cant hear the turbo working. there are two hoses behind the engine by the turbo the thinner vaccume hose is right by the down pipe and can easily be damaged by the heat from the exhaust. or due to the heat it can stretch and slide out from under the hose clamps the best solution is to purchase a samco boost hose kit they cost around $220.00 to $240.00, and will most likley be on backorder for 6 to 8 weeks nomatter where you buy it from because the Mk IV gti is getting old and the demand isn't what it once was. the cheaper solution, and the solution I used on my car was to spend $1.79 on a 4 pack of hose clamps at the hardware store and reattatch the hose while I wait for my boost hose kit. it will also help to buy exhaust wrap tape wich insulates your downpipe and keeps heat away from your engine, and turbo hoses. I hoped this helped. If your boost gauge isn't showing any boost i am not sure what to exept examine the whole enging compartment while the engine is running and feel along all of the hoses looking for a leak. depending on your mileage on the car you could just need a new turbo charger. the cheapest I have found them is at www.kineticmotorsport.com a new borg warner K03 sport is $798.00 and about $40.00 more with the instalation hardware. they also have the K04, and K05 but you need to upgrade a lot of other engine componants to handle the larger boost.

SOURCE: white smoke from tail pipe

It often means that you are burning antifreeze. You asked if it needs antifreeze, have you noticed any leaking out of the reservoir tank while you are running it? Sometimes when the head gasket goes it will produce a passage for the antifreeze to pass from the capillaries into the combustion chamber. It is easy to check if you have an air compressor. Remove one of the rear sparkplugs and the radiator cap. Fill the radiator and then push some air into the sparkplug hole (get a good seal in case a valve is open). Repeat with all the cylinders and watch for air bubbles coming up into the radiator. If bubbles come up or fluid is pumped out, the head gasket is blown and must be replaced. It is more likely to happen at the back of the engine because it is farthest away from the fan and therefore gets less cooling. Also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings.

It could be the waste gate that controls the turbo boost. Check your lower inter-cooler tubing from the inter-cooler to the turbo just to double check and make sure it's all buttoned up. If it's the bearing, there would be lots of blue smoke from the tail pipe. Good luck and keep me posted.

When I'm driving my 03 20th anniversary gti as soon as the turbo starts I hear it breathing way to much air then I lose all power and the epc light is on help me please


your issue is a boost leak check all the boost pipes making sure the pipes are on properly and the clamps are fastened and seated and position correctly.start with the pipe from the airbox to the turbo. Then the pipes from the turbo to intercooler from intercooler to intake throttle body.

1992 Peterbilt 379 feels sluggish pulling load up hill and is blowing black smoke


have a turbo boost pressure test done under load on a chassis dyno
under load the boost should be right up
check for leaks in the intercooler hose fittings or cracks in the intercooler
black smoke under load indicates a faulty turbo or turbo air leaks.

Po299 turbo underboost problem


Check that the turbo's charge pipes aren't leaking anywhere. (The boost side, to the intercooler, to the manifold).

If they're not, check for exhaust leaks.

If that's not it, the turbo isn't functioning properly, or the wastegate (bypass valve) is stuck open.

Blows black smoke when running 2600 rpm and boost goes down


I assume its the 6.0L diesel...If so sigh......double sigh.. I had one of these...triple sigh. I need a bit more clarification. How many km on the engine/vehicle. Also, you say that it blows black smoke while running at a constant speed at 2600 rpm, or while you are accelerating to 2600 rpm. Also, when you say the boost goes down, does it decrease by itself, or when the throttle is let off. The boost naturally goes down when the throttle is released (not trying to be a ****, i dont know how much you know). However, if the boost is going down by itself, while the engine is under load (its not supposed to, it should stay constant) it could be a couple of things, which "can" contribute to black smoke. If there is a leak anywhere from the turbo to the intake of the engine, it will cause the engine to get less boost, which means less air into the cylinders, which means black smoke. Check all of the connectors/tubing coming from the turbo to the intercooler, and from the intercooler to the intake manifold and see if there are any problems. The more costly problems which results in boost going down, and black smoke, deals with a problem with the wastegate on the turbo (controls how much boost is produced, and when too much is being made, it will bleed off excess pressure). So if your wastegate is malfunctioning, your boost will go down and you will get black smoke cause the engine is not getting enough air. also, around 160km...80mi, the injectors "can" start to go on the 6.0L diesels....I would check the turbo for leaks, the tubing for leaks, and the intercooler for leaks (a big rock can punch a hole in radiators and intercoolers...intercooler will be in front of the radiator). I hope this helps

My 2001 td5 feels like the turbo boost is not coming in and it sounds like there is induction roar or fan noise,intercooler hoses have bee checked.


Can be two things.
1) Wastegate modulator - £20 solenoid that sits under the intake hose.
2) Wastegate actuator - £variable, not technically a spare, but may be able to buy one from a failed turbo at your local stealer. Mine had been worn through against the steel coil from the engine breather hose.

I have a focus 2litre zetec with a turbo conversion, it was producing 300 bhp at 17psi, had the turbo reconditioned as it was smoking now max boost on the guage shows about 12 psi.i have checked the boost...


The wastegate may be mal-adjusted now after fitting the new turbo, it sounds like it is shunting boost pressure down the exhaust thru the wastegate valve which is vacuum operated.

Boost problem


Check vacuum pump. Be sure lines are good all the way to to wastegate soleniod. be sure wastegate solenoid has power. Confirm rod is connected to solenoid and turbo wastegate.
Also check all plumbing for leaks.

Doesn't seem that the turbo is working


with the engine cold remove the turbo outlet hose and check for free rotation of the spindle. if it is ok check the wastegate capsule link arm mechanism is not seized as this is fairly common. if all is ok check the pipe work from the turbo outlet to the intercooler (lh side below airfilter headlaamp area) then from intercooler through up to inlet manifold. if all is ok, get a manual pressure gauge on the take off port at rear of inlet manifold should be a pipe blocked off with a rubber bung (lh side back of manifold) (lh side is gear box side of engine) drive car an see what the gauge reads. if it is registering boost then is often the manual boost transducer module on the right hand wheel arch by the cam belt cover that is not working so boost is there just does not register in the car.full boost is not achieved until car is at normal operating temp. if no boost turbo may need checking for wastegate operation or damage on the exhaust side. Hope this helps

Turbo


okay, for a 16g on a 2g you should get an install kit. its the easiest way to do it. you could also piece your own together. i would recomend getting one HERE .

for a complete step by step guide w/ pics, check out the VFAQ

now i hope your 16g came with a wastegate actuator because you can't use the one off of the T25. if it didn't come with one, you can use a 1g actuator off of either the 14b or the 13g.

now, the internal wastegate/wastegate actuator isn't adjustable.
for more boost, you can get a boost controller, or
if you want to increase your boost by 2-3psi you can remove the restrictor in the wastegate solenoid. here is a step-by-step guide for removing it.
(if you want to run more boost than that your gonna want to get larger fuel injectors first.)

if your just running a stock ecu, no tuning is required. but if you already have a tunable system (like DSM Link, E-manage, AEM or even a SAFC) it wouldn't hurt to adjust the tune a little.
