Question about 2001 Mercedes-Benz C-Class

Sprinter 313 black exhaust smoke

Our team van 2001 313cdi seems to make a lot of very sooty black exhaust, mostly under full throttle hen accelerating.
Air filter is clean, and fuel consumption doesn't appear appreciably affected. Emissions seem OK on the Mot too.
But it's a bit embarrasing, and tends to make anything being towed filthy.
Any ideas anyone?

Possibly the turbo check the hose from the turbo to the intercooler rad aslo check the blades of the turbo for catching the casing and for lift dont forget mercedes turbos have very slight lift anyway.

My 1992 Mitsubishi L300 van doesnt run properly. can i get answers?

Your van has a 4G60 series(62/63/64) engine, and is now 25 years old. Loss of power can be caused by many things at this age. Most likely is worn valve stems, leaking valves, and loss of compression. Could be a failing head gasket. The first step is do dry and wet compression test, then a leak down test. If there is a lot of blue exhaust smoke, the engine is burning oil (worn head or/and piston rings). If there's white smoke, its burning coolant, and you have a blown head gasket.

Assuming the rest of the van is adequately mechanically sound, the best approach is likely rebuilding the engine with new rings, possibly rebore for oversize pistons, and a re-manufactured head.

Would a faulty egr valve on my 02 PT Cruiser 2.2crd cause excessive black smoke and injector knock under full throttle....thanks

black smoke is over fueling and although the turbo appears to spin ok the vale variation actuator may not be operating correctly
there are vanes in the exhaust turbine housing that are altered to increase the exhaust gas flow onto the turbine blades for quicker acceleration and these vanes are operated by a vacuum actuator and rod by a sensor
the vanes are subject to extreme heat and can rust stuck open or the hose gets hard and cracks
s not allowing the vanes to work
I would be concentrating in this area before the EGR valve
run the fault codes as well to get a better idea of the possible fault as some systems only put the light on for extreme conditions in engine and transmission

My BMW 525i pcv tubes was broken replaced all cleaned the icv had a lot of smoke cleared up within a week .seemed to have fixed but now I have small trail of sooty smoke

As a general rule black smoke is soot from excess fuel, white smoke is either steam or a great deal of unburned fuel (mainly diesels) and blue or blue/grey smoke is burning oil.

A trail of sooty smoke would indicate too much fuel is entering the cylinders. Perhaps you have a dribbling injector or a faulty sensor or perhaps your injectors are old and worn with bad spray patterns.

At full throttle car doesn't want to accelerate. runs good just cruising around

Fuel or air restrictions. Filters first, then look at the catalytic converters.

1996 v6 chevy silverado idles fine but once you hit the throttle it's as if it's not getting enough fuel. Any suggestions? Catalytic converter maybe?

run fault codes and look for throttle position sensor problem. cat converter problems are apparent at high RPM's under load as the cat converter blocks the exhaust pipe.

Poor acceleration

As you haven't stated if its petrol or diesel, I can only give you a general check list. 1. fuel pressure/delivery rate/fuel pressure regulator. 2. fuel filter. 3. intake manifold air control solenoid. 4. air intake system/vacuum system - leaks/blockage. 5.air filter. 6. exhaust system/catalytic converter. 7. engine compression. 8. ignition system. 9. injectors. 10. engine management system - connections. 11. crankshaft position sensor. 12. evaporative emission (EVAP) canister. 13. Mass air flow sensor (MAF). 14. Throttle position (TP) sensor. 15. Engine/clutch/breaks condition. 16. Engine control module (ECM). It seems a lot to check, but that is the list given from a data sheet. Knock yourself out and have fun.
