Extreme engine smoke

What colour is the smoke, black, blue or white? The colour will help indicate possible causes.

It smoke coming from engine when you open hood or from exhaust?

Try and determine the most prominent colour, this is important, black over fuel, blue oil burning, white/Grey coolant in the combustion chamber.

First thing to do is make sure all levels are correct and get any leaks fixed, smoke out the exhaust is internal problems, if the engine oil is very much over filled this can smoke, check this first and correct the levels, start here.

Can't comment until the exact problem has been identified, sounds like this mechanic is not very sure about what he is doing, I think its time to find one that does.

Mark (mhpautos)

He should give it a good wash down first.

I would be getting a second opinion on this work now, as you said the engine has only 70K on it, there is no way it should be needing a re build, is this mechanic Benz trained? I would strongly suggest getting a second opinion as some of his opinions are a bit of a worry, regarding burning off excess oil and not washing down to check for leaks, all basic mechanical practice.

They should be able to give you a better diagnosis than what I have been reading, as for the re build, I would be getting the comps check do a leak down test and a vacuum test, checking oil pressures at specific engine speeds, this information will give them a better understanding of what is going on, as for just offering a full re build or a change over unit with out any real diagionstic work is not how I would be doing the job, either way it will cot a lot of money, if I w3as spending it I would want to know exactly what is going on, at least they can pull the heads and check for damage, but the tests mentioned will tell them a lot about what is going on inside the engine.

Get that second opinion, there are too many so called mechanics out there ready to empty your bank account, this bloke is sounding very suspicious indeed.

Mark (mhpautos)

What is is it with these blokes? Can't they give a sensible and accurate diagnosis? You tell them for me that they should be giving you a full description as to what has gone wrong, just saying the top end is gone is rather pathetic, and with this information they want you to spend thousands, what do they reckon it is Christmas or something. Try and get some details on what they believe is damaged.
