Okay so around month ago I bought this 02 civic ex. No longer than a 3 weeks later I had to replace the head gasket and took it to a shop nearby. I've now had it back for a couple weeks and have noticed I'm losing oil or burning oil and I want to know what the possible causes could be. Any ideas would help. I know it could be a faulty head gasket or maybe it could be I need a rebuild. Please give me some other ideas

 

bad oil pump?

 

I have that same problem with my EM2 1.7 VTEC... I changed the head gasket and after about 1-2weeks I noticed that oil consumption was about 2 litres/1000km. I'm sure that the head gasket replacement was done with 100% quality. (I have been car mechanic more than 10 years.) There's not external leaks!

When I bought the car year ago, it was burning/eating oil but after Forte flush and oil change, it stopped and after the head gasket replacement it started again. I'm using Castrol magnatec 5W-40 oil.
