Engine/Transmission (1994 - 1998) Soot on turbo intake

[CGomulka]

I removed the intake hose from my BHAF when changing oil the other day, I noticed that there is some fine soot on the inside rim and compressor blades of my turbo. Is this normal or is it time for a new BHAF (or something else?) Thanks.

I have had soot on my intake for quite some time just figured the seals were starting to go. Now about 22k i think my bearings are going... . I would think about getting a rebuild kit and rebuild it if you think you can... I will rebuilding mine this week... Good luck, Marc

How did the rebuild go? I noticed soot and oil mixture on the compressor side of the my turbo. Is this normal? I have 196,000 miles on the engine with original OE turbo. Do I need to rebuild it?

i've seen oil/soot on the intake side caused by over oiling gauze type filters and exhaust leaks.

I've seen dust and Oil from over oiled filters that don't catch the fine dirt. I've got a Fleetguard BHAF and the turbo stays clean. I've seen friends trucks with hardly any miles on a new oiled filter that left stuff on the turbo. One had enough oil go into the tubing that when he added a box he couldn't keep the boot on any more.



I cut (not drilled) a hole in the end of mine and installed the stock filter minder which is how I determine when a new filter is needed.
