I have an s13 with a black top sr20det. Im getting some bluish smoke at idle but not all the time... I come up to a stop light and no smoke. the next stop light there is smoke. It is defiantly oil burning.

I just pulled off my turbo thinking it was that but the exhaust side does not look wet or black at all. Just a light tan color. It does have some side to side play as well as a tiny but of in and out play.

What would be your best guess at what is causing this smoke?

Also I found a kinked oil return hose and it has been replaced but was probably like that for a while

Is it still smoking since you replaced the oil return line?

/\ Yes it is... I dont think it is as bad but that could just be me. I can take some pics of the removed turbo if that would help. Like I said, the exhaust side of the turbo looks fine. a whitish tan color.

Also... I found a bunch of oil in the intake tube for the turbo. Could have come from the valve cover hose or the turbo seals... I dont know.

And I just took off my fmic and there was no sign of oil in it.

UPDATE: I did an oil change (15208-53J00 filter and 15w40 rotela T) and so far no smoke. I think it had 10w30 before. I know the manual says 10w30 but oh well. I have read many posts about people running other weights with no problems.

On to the outcome. NO SMOKE!!! So far im smoke free so I guess only time will tell. Hopefully the heavier oil will help with the small amount that was passing through the turbo seal. If not, s15 turbo it is.

Yeah that sounds like a classic turbo oil seal. The heavier oil will sometimes work but often you can get away with a restrictor on the oil feed if you have play. Any side to side play can wear the seals. Journal bearing turbos can usually survive a little less pressure especially since that extra pressure is just pushing oil past the seal anyways.

does anyone have more info on where I can buy and how to install a restrictor? I would think you could just buy a different banjo bolt with the smaller hole to restrict the oil. Is this true? I have been searching for about an hour for advice and will keep searching until I find it or someone answers here.

Thanks ahead of time for all your help
