I have owned this car since July 2013, with ~110k miles. Someone broke a timing belt, and when I got it major top end work had been accomplished. It ran ok.
* ORIGINAL PROBLEM -> Car had too lean code 17544 (P1136)
Discovered inlet air hose was faulty - had come apart in several places (replaced)
Believed the head gasket failed (had not) due to unexplained oil leak, but replaced with AEB head and rebuilt / replaced. New timing belt, new water pump, new head gasket, etc etc, >180psi each cylinder compression.
Turbo had failed - bearings worn. Cracked exhaust housing. Replaced. Now boosting > 17 psi ref [email protected]
Probably need to adjust my wastegate.
In process of repairs, replaced several suspect vacuum lines. Double checked routing. Also replaced several parts in the vacuum assembly, that were suspect. Routing per original.
Not related, replaced all bushings, suspension
parts, motor, transmission, dogbone mounts. Car runs like new / straight / true.
Replaced turbo-back exhaust with 42dd 3" street legal including high flow cat. (DID NOT REPLACE O2 sensors, used original)Note that in a previous repair, I had several ABS codes mostly relating to G201 - replaced the ABS unit in its entirety about 10 months ago with a used unit, and it cleared all codes.
The pedal has never felt 'right' - immediately after starting the car, if I start at boost then try to brake, I have no power assist. I also note if I run on the highway with cruise control, I have to stomp on the pedal to get it to stop - no power assist.
