Siena:
Does your Volkswagen LT have a year? What's the engine size??

eherbal:
i drive the lt 28 diesel. had the turbo removed .to maintain your turbo engine,let it idle for 1 min before switching off the engine. let it run for 3mins in the mornings before driving off.

emperoracro:

Pls what do u mean by a year?
About the engine size, are u refering to the physical size or what?

emperoracro:
This is d bus

oktawian:
First check the engine compression ...

emperoracro:
It should be
2.4 L D24T turbo I6 (1983-1992) (Diesel engine)

Currently its burning engine oil excessively, my mechanical advised me to ring the engine,i want to b sure before doin that. pls wat is your advice?

eherbal:
if it's burning excess oil. What color of smoke is coming out from the exhaust?

emperoracro:

Wen u first start d engine, it brings out a thick black smoke, wen u throttle hard, it turns whitish

eherbal:
Sorry bro. Im very sorry to say this, but you need to replace the engine.

emperoracro:

I know, but wat cud b d cause of this?
Am thinking of ringing it first, den use it for awhile bfor changing it, wat do u think

oktawian:
kazeem alert

Even if you will change the engine , what if this new engine will be in the same condition ?

Think, You want to change it even when you dont know how to check compression ?

Find some one who knows how to deal with the engines not kazeem.

Regards Oktawian

eherbal:
not a Bad idea if The gasket and rings used are original. anything short of that will see you going back to the mechanic village. I learnt a very bitter lesson from my mechanic. I advice you buy the gasket and rings yourself. MAKE SURE YOU'RE THERE WHEN THE PARTS ARE BEING FIXED PLSSSS.
Another thing? are you the one driving the truck yourself? I see it's a commercial one. it looks very neat.

emperoracro:


I just started using d bus mysef now,
Pls how do i know original gaskets and rings, any spec i sud look out for when buying?

oktawian:
How do you know if the turbo is not causing this smoke ?

First you wrote that you have problem with the power... then i saw that the engine is using lots of oil ...


Check the turbo first ! , take off inlet pipes that goes to the turbo and see how much oil is there ...
you could even take a picture and put it here.

eherbal:
you can take The pain ,go to aspamda market. Trade fair complex, abule pain. the spare parts section there should be able to render some help. everything shouldn't be more than 12 to 15k .I'll try and get you the name later

Thick black smoke on startup is normal if it clears within 15 seconds or so. That's diesel that wasn't burnt completely during startup. White smoke when you accelerate hard means a). coolant being burnt (not likely as your bus will most likely have water in the radiator now), b). unburnt diesel.
Scenario b will most likely be as a result of a million and one things. It will take a competent diesel mechanic to narrow it down (good luck finding one). If the fuel economy isn't too bad, you can drive it till it stops moving while saving up for a new engine. If you have the resources and the time, get it fixed. Since this is a commercial bus, I do not think you want it sleeping around in a mech workshop workshop when it it can be out there making some cool cash for ya. Like Siena said, it won't be an easy undertaking getting it fixed which is why many peeps go down the 'change engine route'. It's entirely my opinion though.

emperoracro:

Yh d black smoke clears almost immediately, what do u think about the turbo and ringing?

Siena:


What year was your VW LT manufactured?

As for engine size, I'm not asking you to grab a tape measure to get dimensions. I'm referring to the engine capacity. Surely, you must know what that is.

9icetoo:

I don't know how to test turbos of that model. I know turbos don't kick in until a certain RPM. I used a scan tool to check mine and boost pressure reported from the MAP sensor was within spec. ringing is a whole different ball game. The cylinder bores would have to be measured assuming it is suffering from low compression. Then what size of rings and pistons to be fitted would be determined from the measurements.
A mech can remove the turbo and inspect it to see if the turbines still behave as they should. Check for leaks in the turbo pipings as well if you are checking the turbo. Remember my earlier post though; if the fuel economy is still okay, you might as well continue driving the bus like that. Please note that diesel engines from your bus era were not particularly fast. In fact, they were slow pokes and took forever to get up to speed. So what you might think is sluggish acceleration might actually be normal.
