TL;DR cracked intake hose, was dumb and limped jeep to work. Should I replace my turbo?
Recently I was driving my 2006 tractor down the interstate when I suddenly lost all my boost and heard a small tornado start blowing under my hood (and a black one came out my exhaust pipe). I immediately shifted into neutral and let off the throttle. The noise stopped, the motor did not over heat, and the massive cloud of black smoke cleared up immediately.
I foolishly drove the Jeep the rest of the way to work since I was close but stayed off the throttle so the turbo would not spool up. I did not realize that if I had lost a turbo seal (as opposed to a cracked hose) it would have pumped all the oil out instantly. Lesson learned!
When I got the Jeep to the shop to assess the damage, I found exactly what I expected: a sizable crack in my intake side CAC hose (and a good bit of liquid oil).
After seeing all that in the intake hose I removed the passenger side hose aswell. I found about the same amount of oil in that hose as I had found on the driver side hose. No cracks, but it went straight to the trash along with the other hose anyway.
My turbo had a lot of wet oil in the exhaust port too.
I felt no play in the turbo shaft and was only about a quart low on oil (limped at least 20 minutes on that blown hose). Every bit of that missing oil seemed to be all over my driver side engine compartment, so I purchased...
- Samco hoses and T-clamps
- CCV assembly (it was leaking anyway)
- A lot of brake cleaner
I cleaned everything off, installed the new hoses, made sure the oil was topped off, and cranked the motor up. No weird noises, no clouds of smoke, and the turbo sounded fine when I blipped the throttle in park. I let the motor run for a few minutes, then checked the insides of the hoses for oil. Everything was dry, so I took a gingerly test drive for ten minutes or so. I still have no oil residue in the hoses (EGR delete and tune 15k back).
You guys think I am probably ok, or should I red-tag the Jeep and get a new turbo? Does all that liquid oil mean I have a leaking seal, or is that just because I had no boost pressure?
