Hummer H3For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.
I has an issue with engine oil leaking, I fixed it by removing the clog in the engine air outlet (near the check valve) after that all the previous problem are gone( smoky engine, oil leak)
the oil reached to the exhaust I have the feeling that the GPF is socked in oil and the engine air-intake area (throttle …etc)
Because i have to push the gasoline paddle to the end to get some power especially in offroad.
i need some advise and feedback how to fix and enhance my car strength
A focused explanation of vehicle history would be wise in getting possible assistance. example: 20xx hummer h3 200,xxx miles Trouble codes Related parts information Related repair information Items in question Etc.
GPF is an abbreviation for: Gasoline Particulate Filter, a device that reduces the amount of fine particulate emissions from gasoline-powered vehicles:
On this side of the pond we have Catalytic converters

I had a major issue in my beloved h3.
during a usual rough off-road trip in desert I retuned back then i found the radiator is mixed with transmission fluid. Unfortunately I had to rebuild the transmission and installed transmission radiator (truecole 30k btu).
Returning back to the subject,
i used wynns gpf cleaner but unfortunately the upstream o2 sensor was stuck three mechanics try to lose it up, but they couldn’t. anyway they open the catalyst then inject the cleaner. Then another issue appeared the upstream o2 sensor was not cleaned so misreading between the sensors appeared. I bought a new upstream sensor waiting to be installed. I have to figure away to remove the old sensor.
