Hey guys.
12 Cruze Eco (so 1.4L)
Manual transmission
62k miles
Maryland, USA
PCV diaphragm failed and valve cover gasket left me sitting the other morning. Throwing P1101 and P015B codes. Engine was smoking like a chimney so I went ahead and replaced the valve cover. Pulled the intake manifold and oil dumped out of the intake tube. I cleaned the intake, gaskets, sealed the hole left behind where the nipple used to be with some jb weld, and put everything back together and test drove it. Ran great.
The next morning, as I got on the interstate, I got a noticeable stutter/jerk at roughly 3500rpm. I commute 75 miles each way, and I pull some relatively steep grades on the interstate. This makes it a little tough to keep the rpm down, but I pulled the hills 20mph slower and a gear lower. Hills that I typically pulled on the higher side of 4th gear were tackled on the lower side of 3rd gear. I commuted back home with the same results this morning.
I checked plugs, they were white/ashy and all around .28. One or two were actually closer to .25 before I adjusted them. I pulled the corrugated hose from the turbo side to find that rubber "check valve" is also gone. I don't have Andrei's kit yet. I'm in the process of ordering it. Planning to just go with the v3. Am I overpressurizing the crankcase as boost backfeeds from that corrugated hose? That is about the only thing I can think of unless maybe the JB weld didn't seal entirely, but I'm fairly sure it did. Still searching. I apologize if it is here, but I'm not seeing it. Thanks in advance
