Turbo replacement should take a weekend for a first timer w/ a mastercrap set & alldatadiy.com
Get the turbo replacement gasket set from your local stealership.
A Mechanic should take 2 hours
Make sure you have a Torx bit set awsell, if you need more room to work on the turbo, drop front bumper and remove upper radiator mounts and it will tilt forward enough to get a full arm in.
Other then that, dont let it intimidate you, just start pulling stuff off until the turbo drops.
The 1.4 is a dream to work on in the cruze. I could change out a stock turbo faster then a Subaru WRX owner can change his spark plugs
I used a 1/4" socket with wobble extensions of different lengths. The DP/cat can come off if need be just be sure to get the 3 flange bolts and the hidden bolt that holds it to the bracket on the engine.Does anyone know of a good way to get the manifold bolts off the bottom side of the exhaust manifold??? I am thinking at this point it would be wise to drop the whole exhaust system from the turbo back to the cat?
If you are talking about the crack running downward from the wastegate seat, then I think you can count on practically all of them having that crack there.ALSO note i am seeing a lot of cracked Turbos now
No need to remove the oil filter.Also might help overall to remove the oil filter to try and get the oil to drain back to the pan so less comes out the feed line and port.
