Blown head gasket?
Hello everyone. This is my first post here so I'm sorry if I'm doing something wrong.
So we just bought a 2005 Honda Civic for $1000. It only has 158k miles but it had a "radiator problem". We checked the codes and it had 53 of them. Most were due to a bad cam position sensor which we replaced but it was still idling very rough and felt sluggish. It still has 10 codes. All for o2 sensors/heaters and a faulty buckle.
We then proceeded to do a compression test with the results: 100, 95, 50, 100
After that I used the compression tester tube that screws into the sparkplug hole and hooked the compressor up to it after getting cyl #3 to TDC on the compression stroke. I brought the compressor up to 100 psi and the radiator started gurgling aggressively. There wasn't enough antifreeze to see it bubble but that's sure what it sounded like.
So I came to the conclusion after looking at other posts that it sounds like either a blown head gasket or a cracked head. Does that sound right?
Should I just pull the head and see?
