How much oil....?

[aviologist]

So the old pile(MKII JettaTD) is still smoking a fair bit on most power settings. I have the smoke screw back to what looks like the factory settings and have not done any mods at all. The timing was checked and injectors pop tested.I don't mind a little but it is a bit much. So I was poking around and noticed  engine oil around the rubber hose from the turbo to the intake. My first thought is that it is blowing oil out the turbo seal but there is also a fair bit in the crankcase vent hose ( top of valve cover to the intake). Does this mean to much blowby? It doesn't seem to use oil and it only has 264,000km. If the turbo seal is fornicated then it would smoke a bit more I pressume but then I really am not to sure and thus the post. Some one must know more than I and hopefully shed some light on this for me. Maybe I should just sell it and be done with it......

So after doing some reading on this and other sites I find that it is a fairly normal occurance for there to be some oil in the intake. Apparently the oil seperator is not really up to the task of taking it all out and thats why there are those that add on a 'catch can' to keep it from getting to much. That sounds like more work and it is oil after all, it will burn! I have enough work just keeping it going every day let alone adding on stuff that were never ment to be there. As for the smoke....

Yeah, the oil is totally normal and nothing to worry about.  The VW engineers even listed it as a good thing in their SAE paper on these engines - it adds lubrication for the valves, decreasing valve seat wear.

Smoke - what colour, and what situation?  Before the turbo spins up? After it's going?

There isn't really a 'factory' setting with the smoke screw.  There's the setting a guy with a pump test bench will set it to, but that's highly dependent on the individual pump.  The collar on the screw is there to prevent you from cranking it in too much, but it isn't the "right" place for things to be set.  On my car if I bottom out the collar I'm leaving huge soot clouds behind me.

Try backing the screw out a tad and see if it improves things.  Like 1/8 of a turn at a time, tops...
