Blow-by issue

[Rich12247]

Just bought my a 1989 7.3idi. Previous owner tried installing turbo.Lots of oil coming out of exhaust side of turbo. Engine was resealed but piston rings were not replaced.

Do you get substantial blowby with engine running and oil filler cap removed? Exhaust color?

That's a strange looking intake hat & turbo setup--any brand markings?
I've never seen an oil feed line that wasn't wrapped in braided steel.

This only thing I see that had a name on it was the upper intake.it has banks on it. Looks like everything else was just pieced together parts.

If it has that much oil coming out of the turbo exhaust housing, oil must not be draining correctly from the turbo back to the engine.

And, how is the crankcase vented.

Or there's a bad seal in the turbo letting oil into the exhaust side.

I can't say about the turbo itself, but that's a first gen Banks set up where the intake hat has been cut off of the air cleaner.

Answer: looks like there’s a catch can coming from the driver side valve cover.

Yes, I have never seen this set up too. I’m planning on replacing the oil feed line. It’s a hydraulic hose.

The picture of your blow by out of the oil fill doesn't look very bad. These engines are designed with large ring gaps so they do have quite a bit of blow by.
