where does my oil go???

[Firebird69]

running my fairly new engine, I´m missing about 1l on 300km.
no leaks and no smoke out the exhaust

I´m dispaired...

(I´m running an AAN, 7A cams, 550 GT-K, 81,5 JE-Pistons, stock oil pump, 10W60 Castrol, 1,3 bar boost, ECU481)

you may check out the CO value... you may have som oilleak out the hot side of turbo....

wouldnt that cause white smoke though?

[Jamo]

Why are you using 10w60 out of interest?

[Firebird69]

the turbo is brand new...so that shouldn´t be it...
would you say pistons are a possibility? but would cause smoke also!?!?!?!
10W60 was a recommenation...and lots of 20VT are ran with it, why that question?

If you are 100% sure it does not smoke, then you have an oil leak somewhere.

No reason to run 10w60 unless it is very hot and you are getting very high oil temps.
I would say even for high temps you only need 10w50 .
The fact that you are getting through this much oil and it is the thick stuff is even more worrying.

The fact that you have a new turbo makes me think it is more likely this as I have seen a few 'new' turbos piss oil into the down pipe. The other thing to note is sometime they do it when cold when you not booting it so you don't see any smoke, then when there hot they leek less.
I would undo the downpipe joint and see what is going on after a cold start up and a few mins running.

Well, that sound like a good idea...It throws out a lot of grap, when I strat it from the cold...
I just did and had it running 3 mins...

strange thing is that I changed the turbo because of the oil leak and niw the same thing with a new one??????

[Firebird69]

and the stoff is a little oily but more like soot mixed with water...

My turbo was new and leaking oil in hotside, only found out because downpipe to middle section was loose and dripping small amounts of oil.

[Firebird69]

well...that would suck...
