Hey all,

Trying to chase down an oil leak in a 2012 Chevy Cruze 1.4. Around a year ago the car starting leaking oil from what appeared to be multiple places onto the ground, and throwing a few check engine lights. After browsing the forum I determined the PCV valve in my intake had packed up and left town. I ordered the repair kit from Xtreme Revolution, installed it, and the codes and oil leak both cleared themselves. Fast forward to a year later, and the car is leaking oil again. It was leaking multiple drops from multiple points over the course of a night. I degreased and pressure washed the engine, and brake cleaned the spots I could not reach with the wand. I let the car run for a while, and noticed a drop forming at the oil cooler. I brake cleaned the spot and it returned minutes after. After browsing the forum I determined the oil cooler seals were the likely culprit. I ordered new gaskets from GM and installed them, along with a new turbo feed line. After this repair I brake cleaned the engine again. A week later I have more oil on the ground, and what appears to be oil leaks in multiple spots. I have attached photos of various spots where oil drops are forming. Oil is currently covering and dripping off of the check valve I installed, the starter, the oil cooler, the ac compressor, and is wet on nearly the entire bottom half of engine. Since the initial PCV issue was causing multiple leaks as well, I have began to look in that direction again. I smoke tested the intake to see if the screw used to block off the old pcv valve had failed. I smoked the intake using the new connection provided with the xtreme revolution kit where the hose coming off the new check valve connects to the top of the intake. I am not 100% this test was correct to determine if the screw had failed. I did not see any smoke making it through the screw/epoxy after popping off the corrugated hose. I have also checked the check valve at the turbo and it seems to be working as it should. Thanks in advance for any pointers.

For what’s its worth, after installing the fix kit I had to replace the intake manifold gasket. I chose to reuse it, bad idea. Whole back is the engine for coated in oil. Was dripping from the check valve like yours as well onto the starter

Thebigzeus, thanks for showing me that. I too reused the old intake manifold gasket when installing the pcv fix kit. I would say my next step should be replace the gasket, clean, and reassess.
